Introduction. The correction of paediatric scoliosis is a surgical procedure in which substantial bleeding occurs, and which historically has been associated with high levels of blood transfusion. Transfusions are associated with risks of infection, allergic reactions, volume overload and immunosuppression. The purpose of our study was to evaluate the efficacy of a care pathway implemented at St Thomas' hospital over ten years with a focus on minimising the need for blood transfusions. A Spinal Surgery Care Pathway was developed including: nurse-led clinics facilitating pre-operative haemoglobin optimisation; intra operative cell-salvage, the use of tranexamic acid, and a transfusion criteria awareness programme. Methods. We reviewed the records of all patients 18 years of age or younger undergoing spinal corrective surgery between 2000 and 2010. Collating data from the surgical records and haematology laboratory, we identified the proportion of patients requiring transfusion and the respective volume of blood or blood products transfused. Results. 534 spinal procedures were undertaken on patients over the decade of interest. Over this time, the proportion of patients requiring transfusion reduced from 83.3% in 2000, to 6.4% in 2010 (p < 0.001); a consistent year on year reduction was witnessed between 2005 and 2010. In those requiring transfusion, the volume of packed red cells transfused fell from a mean of 7.7 units in 2000, to 1.5 units in 2010 (p < 0.001). These results were despite an increase in posterior fusions, associated with higher bleeding, from 50.0% to 79.4% over the same time period. Conclusion. Over ten years, we have demonstrated that the implementation of a multifaceted, multidisciplinary pathway together with challenging cultural attitudes to blood transfusion, can dramatically and sustainably reduce the need for blood transfusion and the risks associated therewith. These data lends weight to the adoption of such a care pathway in paediatric scoliosis surgery

Abstract. Background. Blood transfusion requirement after primary total hip replacements (THR) and total knee replacements (TKR) was found to be related to increased post-operative complications rate and length of hospital stay. Pre-operative haemoglobin level remains the single most important factor determining the requirement for post-operative blood transfusion. Methods. We carried out a local retrospective audit of 977 THRs and TKRs in 2019. Pre-operative and pre-transfusion haemoglobin levels for transfused group of patients were recorded. Results. A total of 977 patients had THRs and TKRs of which 34 (3.5%) had blood transfusions. From the 437 THRs, 24(5.5%) had bloods transfusions of which 19 were female. From the 540 TKRs 10(1.8%) were transfused, 9 were female. The average length of stay (LOS) for those transfused was 6.8 days and the average LOS for our trust is 3.2 days. Conclusion. The incidence of blood transfusion after primary THR or TKR was 3.5% in 2019. The majority of patients who received post-operative blood transfusion were found to have pre-operative haemoglobin level below 12 g/dl representing 61.7% of all the transfused patients. Transfused patients had more than double the average expected length of stay. The incidence of blood transfusion and associated risks can be improved by early detection and proper management of pre-op anaemia. Pre-assessment clinic has got a pivotal role but needs reminding of pre-op haemoglobin management strategies.

Shoulder replacement surgery is a well-established orthopaedic procedure designed to significantly enhance patients’ quality of life. However, the prevailing preoperative admission practices within our tertiary shoulder surgery unit involve a two-stage group and save testing process, necessitating an admission on the evening before surgery. This protocol may unnecessarily prolong hospital stays without yielding substantial clinical benefits. The principal aim of our study is to assess the necessity of conducting two preoperative group and save blood tests and to evaluate the requirement for blood transfusions in shoulder arthroplasty surgeries. A secondary objective is to reduce hospital stay durations and the associated admission costs for patients undergoing shoulder arthroplasty. We conducted a retrospective observational study covering the period from 1st January 2023 to 31st August 2023, collecting data from shoulder arthroplasty procedures across three hospitals within the Aneurin Bevan University Health Board. Our analysis included 21 total shoulder replacement cases and 13 reverse shoulder replacement cases. Notably, none of the patients required postoperative blood transfusions. The mean haemoglobin drop observed was 14 g/L for total shoulder replacements and 15 g/L for reverse shoulder replacements. The mean elective admission duration was 2.4 nights for total shoulder replacements and 2 nights for reverse shoulder replacements. Our data indicated that hospital stays were extended by one night primarily due to the preoperative group and save blood tests. In light of these findings, we propose a more streamlined admission process for elective shoulder replacement surgery, eliminating the need for the evening-before-surgery group and save testing. Hospital admissions in these units incur a cost of approximately £500 per night, while the group and save blood tests cost around £30 each. This revised admission procedure is expected to optimise the use of healthcare resources and improve patient satisfaction without compromising clinical care

This study aimed to identify factors associated with increased rates of blood transfusion in patients with adolescent idiopathic scoliosis (AIS) treated with posterior spinal fusion (PSF). A retrospective case-control study was performed for AIS patients treated at a large children's hospital between August 2018 and December 2020. All patients with a diagnosis of AIS were evaluated. Data on patient demographics, AIS, and transfusion parameters were collected. Univariate regression and multivariate logistic modeling were utilized to assess risk factors associated with requiring transfusion. Odds ratios (OR) and 95% confidence interval (CI) were calculated. Surgeries were done by three surgeons and thirty anesthesiologists. To quantify the influence of anesthesia practice preferences a categorical variable was defined as “higher-transfusion practice preference”, for the provider with the highest rate of transfusion. A total of 157 AIS patients were included, of whom 56 were transfused RBC units (cases), and 101 did not receive any RBC transfusion (controls). On univariate analysis, the following variables were significantly correlated with receiving RBC transfusion: “higher-transfusion practice preference,” “administration of crystalloids,” “receiving fresh frozen plasma (FFP),” “receiving platelets,” “pre-operative hemoglobin,” “cell saver volume,” and “surgical time.” On multiple regression modeling, “pre-operative hemoglobin less than 120 g/L” (OR 14.05, 95% CI: 1.951 to 135.7) and “higher-transfusion practice preference” (OR 11.84, 95% CI: 2.505 to 63.65) were found to be meaningfully and significantly predictive of RBC transfusion. In this cohort, we identified pre-operative hemoglobin of 120 g/L as a critical threshold for requiring transfusion. In addition, we identified significant contribution from anesthesia transfusion practice preferences. Our multivariate model indicated that these two factors are the major significant contributors to allogenic blood transfusion. Although further studies are required to better understand factors contributing to transfusion in AIS patients, we suggest standardized, peri-operative evidence-based strategies to potentially help reduce variations due to individual provider preferences

Prior to the introduction of steroid management in Duchenne Muscular Dystrophy (DMD), the prevalence of scoliosis approached 100%, concomitant with progressive decreases in pulmonary function. As such, early scoliosis correction (at 20-25°) was advocated, prior to substantial pulmonary function decline. With improved pulmonary function and delayed curve progression with steroid treatment, the role of early surgery has been questioned. The purpose of this study was to compare the post-operative outcomes of early versus late scoliosis correction in DMD. We hypothesize that performing later surgery with larger curves would not lead to worse post-operative complications. Retrospective cohort study. Patients with DMD who underwent posterior scoliosis correction, had pre-operative pulmonary function testing, and at least 1-year post-operative follow-up, were included; divided into 2 Groups by pre-operative curve angle – 1: ≤45°, 2: >45°. Primary outcome was post-operative complications by Clavien-Dindo (CD) grading. Secondary outcomes included: age at surgery, forced vital capacity (FVC), steroid utilization, fractional shortening (FS) by echocardiogram, surgery duration, blood transfusion requirements, ICU length of stay (LOS), days intubated post-operatively, hospital LOS, infection, curve correction. Two-tailed t-test and chi-square testing were used for analysis of patient factors and CD complication grade, respectively. 31 patients met the inclusion criteria, with a mean total follow-up of 8.3±3.2 years. Steroid treatment (prednisone, deflazacort) was utilized for 21 (67.7%) patients, for a mean duration of 8.2±4.0 years. Groups were comparable for steroid use, FVC, echo FS, and age at surgery (p>0.05). Primary curve angle was 31.7±10.4° and 58.3±11.1° for Groups 1 and 2, respectively (p 0.05). Surgery duration, ICU LOS, days intubated, hospital LOS, were also not different between Groups. For the entire cohort, however, the overall complication rate was higher for patients with steroid treatment [61.9% vs 10%, respectively (p=0.008)], the majority being CDII. Neither FVC nor echo FS were different between Groups at final follow-up (p=0.6; p=0.4, respectively). Post-operative complication rates were not different for early and late scoliosis correction in DMD. In general, however, patients undergoing steroid treatment were at higher risk of blood transfusion and deep infection. Delaying scoliosis correction in DMD while PF is favourable is reasonable, but patients with prior steroid treatment should be counseled regarding the higher risk of complications

Limited strong data exists in current literature comparing the 90-day morbidity and mortality following general or spinal anesthetic in patients who underwent total hip or knee arthroplasty, especially between matched cohorts. Because of this, there continues to be an ongoing debate regarding the risks and benefits of using general versus spinal anesthetic for patients undergoing elective total hip arthroplasty (THA) or total knee arthroplasty (TKA) for end-stage osteoarthritis. The Alberta Bone and Joint Health Institute (ABJHI) database was searched to identify all patients who underwent either primary THA or TKA between April 2005 and December 2015. Those identified were matched 1:1 based on age, sex, type of joint replacement (THA or TKA), American Society of Anesthesiologists (ASA) score, and anesthetic type. Patients were stratified into two groups based on whether they received a general anesthesia (GA) or a spinal anesthesia (SA) at the time of their index surgery. Perioperative complications (medical events, mechanical events, deep infection, need for blood transfusion), length of stay (LOS), 30-day readmission, and 90-day mortality were compared between cohorts. Included in this study are 5,580 patients who underwent THA and 7,712 patient who underwent TKA. All were successfully matched based on similar categorical criteria (THA, 2,790 matched-pairs, TKA, 3,856 matched-pairs). Following stratifications of cohorts, no statistical differences were appreciated between patient baseline demographics. Patients who underwent GA showed a trend towards higher 90-day mortality, however no statistical differences were found between anesthetic type on rates of 90-day mortality following either THA or TKA (THA, p = 0.290, TKA, p = 0.291). Considering this, patients who underwent THA with SA experienced fewer 90-day complications (medical events, p = 0.022, mechanical events, p = 0.017), needed fewer blood transfusions (p < 0 .001), and required shorter LOS (p = 0.038). Moreover, patient who underwent TKA with SA had fewer blood transfusion (p < 0 .001), 30-day readmission rates (p = 0.011), and fewer deep infections (p = 0.030) that required additional surgery compared to those in the GA cohort. Regardless of surgery performed, patients in the SA cohorts were more commonly discharged home without requiring additional support (i.e. home care). General anesthesia during THA and TKA appears to be associated with increased 90-day morbidity and more frequent need for allogenic blood transfusion. No statistical difference in 90-day mortality is reported between cohorts for either THA or TKA, yet a trend is appreciated favoring SA. Surgeons who commonly perform these surgeries should consider the added benefits of spinal anesthesia for those patients who are candidates

Patients undergoing Joint Arthroplasty received a significant proportion of blood transfusions. In this study, we compared the risk of Deep Infection, and Superficial Infection post operation following Primary Total Hip or Knee replacement in blood-transfused and non-blood-transfused patients. Cohort of patients who underwent primary total Hip or Knee Arthroplasty from April 2012 to March 2015 in Alberta. Patient characteristics, comorbidity, received blood transfusion were collected from electronic medical records, operating room information systems, discharge abstract database, provincial clinical risk grouper data. Deep Infection and Superficial Infection were captured from Provincial Surgical Site Infection Surveillance data. Deep Infection include deep incisional and organ/space infections. Logistic regression analysis were used to compare Deep Infection and Superficial Infection in blood-transfused and non-blood-transfused cohorts, and risk-adjusted for age, gender, procedure type, and co-morbidities. Our study cohort contains 27891 patients, with mean of age at admission was 66.3±10.4, 57.5% female, 49.3% had 1 or more comorbidities. 58.8% underwent Knee Replacement. 11.1% received blood transfusion during hospital stay (Total Hip Replacement (THR) =13.1% and Total Knee Replacement (TKR) =9.7%,). 1.1% had Deep Infection (THR=1.4% and TKR=0.9%) and 0.5% had Superficial Infection (THR=0.5% and TKR=0.5%). Blood-transfused patients got 1.7% Deep Infection and 1.0% Superficial infection. Non-blood-transfused patients got 1.0% Deep Infection and 0.5% Superficial infection. Controlling for age, gender, procedure type, and co-morbidities, the odds of Deep Infection were 1.6 times higher for blood-transfused patients than for non-blood-transfused patients (adjusted odds ratio [OR]=1.6, 95% confidence interval [CI] [1.2–2.2], p=0.004). The odds of Superficial Infection were 2.0 times higher for transfused patients (adjusted OR=2.0, 95% CI [1.3–3.0], p=0.002). Blood transfusion increases Deep Infection and Superficial Infection post-surgery following Primary Total Knee or Hip Replacement. This finding suggests to reduce the unnecessary blood transfusion for patients considering Joint Arthroplasty. Reducing the blood transfusion will save the inpatient cost and decrease the infective complications post-surgery in Hip or Knee Arthroplasty patients

Wound complications are common in patients with soft tissue sarcomas (STS) treated with surgical excision. Limited data is available on predictive factors for wound complications beyond the relationship to neo-adjuvant or adjuvant radiotherapy. Likewise, the association between blood transfusion, patient comorbidities and post-operative outcomes is not well described. In the present study we identified the predictive factors for blood transfusion and wound complications in patients undergoing surgical resection of soft tissue sarcoma from a national cohort. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients who underwent surgical resection of a STS from 2005 to 2013. Primary malignant soft tissue neoplasms were identified using the following ICD-9 codes: 171.2, 171.3 and 171.6. Patients treated with both wide excision and amputation were identified using the current procedural terminology (CPT) codes. Prolonged operative time was defined as greater than 90th percentile of time required per procedure. A multivariable logistic regression model was used to identify associations between patient factors and post-operative wound complications (superficial and deep surgical site infections (SSI), and wound dehiscence). A similar regression model sought to identify prognostic factors for blood transfusion and associations with post-operative outcomes. A total of 788 patients met our inclusion criteria. Of theses, 64.2% had tumours in the lower limb, 23.1% patients had tumours in the upper limb, and 12.7% patients had pelvic tumours. Six hundred and forty patients (81.2%) underwent surgical excision; 148 (18.8%) patients had an amputation. Multivariable logistic regression modeling identified American Society of Anaesthesiologist (ASA) class 3 and 4 (OR=2.3, P=0.03; OR=8.3, P=0.001, respectively), amputation (OR=14.0, P<0.001) and prolonged operative time (OR=4.6, P<0.001) as significant predictors of blood transfusion. Radiotherapy (OR=2.6, P=0.01) and amputation (OR=2.6, P=0.01) were identified as predictors of superficial SSI, whereas ASA class 4 (OR=6.2, P=0.03), prolonged operative time (OR=3.9, P=0.012) and return to the operating room (OR=10.5, P<0.001) were associated with deep SSI. Male gender (OR=1.8, P=0.03), diabetes (OR=2.3, P=0.03), ASA class 3 (OR=2.4, P=0.003), amputation (OR=3.8, P<0.001) and steroids (OR=4.5, P=0.03) were identified as predictors for wound dehiscence and open SSI. A national cohort demonstrates that male gender, diabetes, chronic steroid use, higher ASA score and radiotherapy are associated with an increased incidence of wound complications. One in twenty-three patients undergoing resection of an STS will require a blood transfusion, and this risk is correlated with amputation, prolonged operative time and increased ASA score. Strategies to decrease the risk of blood transfusion and wound complication should be considered for these patient groups

INTRODUCTION. The efficacy of tranexamic acid (TXA) to reduce blood loss in various surgical procedures has been proven. However, there is little data about the effect of TXA on blood loss, rate of blood transfusion and thromboembolic events during periacetabular osteotomy (PAO). The reduction of blood loss during PAO promotes postoperative mobilization and reduces the risk of complications, associated with blood transfusions. The aim of the following study was to determine, if TXA can reduce both blood loss and the rate of blood transfusions. In addition we analyzed whether TXA was associated with an increased risk of thromboembolic events. METHODS. A consecutive series of 96 PAO procedures was reviewed to compare the groups immediately prior to and following the routine implementation of TXA. The TXA group received a continuous infusion of TXA with a rate of 10mg/kg/h. The outcome was blood transfusion rate, total blood loss, length of hospital stay, and thromboembolic events. RESULTS. The rate of autogenic and allogeneic blood transfusion decreased from 62.5% to 12.5% (p<0.001) between the non-TXA and TXA group. The average blood loss (1.9 l ± 0.9 vs. 1.5 l ± 0.7, p <0.01) was significantly reduced in the patients receiving TXA. No cases of postoperative thromboembolic events were identified in either group. The hospital stay was reduced from 10 days to 9 days in the TXA group. DISCUSSION AND CONCLUSION. The utilization of TXA reduced the transfusion rate and blood loss after PAO, without additional adverse effects such as an increased rate of thromboembolic events

Hemorrhage and transfusion requirements in spine surgery are common. This is especially true for thoracic and lumbar fusion surgeries. The purpose of this papersi to determine predictive factors for transfusion and their effect on short-term post-operative outcomes for thoracic and lumbar fusions. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients that underwent lumbar or thoracic fusion surgery from 2010 to 2013. Univariate and multivariate regression analysis was used to determine predictive factors and post-operative complications associated with transfusion. A total of 14,249 patients were included in this study; 13,586 had lumbar fusion and 663 had thoracic fusion surgery. The prevalence of transfusion was 35% for thoracic fusion and 17.5% for lumbar fusion. The multivariate analysis showed that age between 50–60 (OR 1.38, CI: 1.23–1.54), age between 61–70 (OR 1.65, CI: 1.40–1.95), dyspnea (OR 1.11, CI: 1.02–1.23), hypertension (OR 1.14, CI: 1.02–1.27), ASA class (OR 1.73, 1.18–1.45), pre-operative blood transfusion (OR 1.91, CI: 1.04–3.49), and extended surgical time (OR 4.51, CI: 4.09–4.98) were predictors of blood transfusion requirements for lumbar fusion. While only pre-operative BUN (OR 1.04, CI: 1.01–1.06) and extended surgical time (OR 4.70, CI: 3.12–6.96) were predictors of transfusion for thoracic fusion. In contrast, higher pre-operative hematocrit was protective against transfusion. Patients transfused who underwent lumbar fusion had an increased risk to develop superficial wound infection, deep wound infection, venous thromboembolism, myocardial infarction and had longer length of hospital stay. Patients transfused who underwent thoracic fusion were more likely to have venous thromboembolism and extended length of hospital stay. However, mortality was not associated with blood transfusion. This study used a large database to characterise the incidence, predictors and post-operative complications associated with blood transfusion in thoracic and lumbar fusion surgeries. Pre- and post-operative planning for patients deemed to be at high-risk of requiring blood transfusion should be considered to reduce post-operative complication in this population

Extended patient waiting lists for assessment and treatment are widely reported for planned elective joint replacement surgery. The development of regionally based Elective Orthopaedic Centres, separate from units that provide acute, urgent or trauma care has been suggested as one solution to provide protected capacity and patient pathways. These centres will adopt protocolised care to allow high volume activity and increased day-case care. We report the plan to establish a new elective orthopaedic centre serving a population of 2.4 million people. A census conducted in 2022 identified that 15000 patients were awaiting joint replacement surgery with predictions for further increases in waiting times. The principle of care will be to offer routine primary arthroplasty surgery for low risk (ASA 1 and 2) patients at a new regional centre. Pre-operative assessment and preparation will be undertaken digitally, virtually and/or in person at local centres close to the where patients live. This requires new and integrated pathways and ways of working. Predicting which patients will require perioperative transfusion of blood products is an important safety and quality consideration for new pathways. We reviewed all cases of hip and knee arthroplasty surgery conducted at our centre over a 12-month period and identified pre-operative patient related predictive factors to allow us to predict the need for the perioperative transfusion of blood products. We examined patient sex, age, pre-operative haemaglobin and platelet count, use of anti-coagulants, weight and body mass index to allow us to construct the Imperial blood transfusion tool. We have used the results of our study and the transfusion tool to propose the patient pathway for the new regional elective orthopaedic centre which we present

Background. There is growing clinical and policy emphasis on minimizing transfusion use in elective joint arthroplasty, but little is known about the degree to which transfusion rates vary across US hospitals. This study aimed to assess hospital-level variation in use of allogeneic blood transfusion in patients undergoing elective joint arthroplasty, and to characterize the extent to which variability is attributable to differences in patient and hospital characteristics. Methods. The study population included 228,316 patients undergoing total knee arthroplasty (TKA) at 922 hospitals and 88,081 patients undergoing total hip arthroplasty (THA) at 606 hospitals from January 1, 2009, to December 31, 2011, in the Nationwide Inpatient Sample database, a 20% stratified sample of US community hospitals. Results. The median hospital transfusion rates were 11.0% (interquartile range, 3.5% to 18.5%) in TKA and 15.9% (interquartile range, 5.4% to 26.2%) in THA. After fully adjusting for patient- and hospital-related factors using mixed-effects logistic regression models, the average predicted probability of blood transfusion use in TKA was 6.3%, with 95% of the hospitals having a predicted probability between 0.37% and 55%. For THA, the average predicted probability of blood transfusion use was 9.5%, with 95% of the hospitals having a predicted probability between 0.57% and 66%. Hospital transfusion rates were inversely associated with hospital procedure volume and directly associated with length of stay. Conclusions. The use of blood transfusion in elective joint arthroplasty varied widely across US hospitals, largely independent of patient case-mix and hospital characteristics

Surgery for DDH is one of the common paediatric orthopaedics procedures in a tertiary care paediatrics hospital. There are no uniformly agreed guidelines about the pre-operative work up related to blood transfusion in DDH surgery. This leads to lack of uniformity in practice, sometimes causes cancellations of operations on the day of surgery (due to no cross matched blood available) and on other occasions wastage of the cross matched blood. The aims of our study were to know the incidence of perioperative blood transfusion in a series of DDH operations and to determine what types of operations/kids have more chances of needing a blood transfusion peri-operatively. We included all children who had surgery for DDH between April 2009 and October 2012 in our institution. We found out which of these children had blood transfusion peri-operatively and reviewed their notes to determine any trends in transfusion requirements. 165 children had operations for DDH during the study period. This included operations ranging from hip open reduction to Ganz osteotomy. 6 out of 165 (4%) were transfused blood. Children needing blood transfusion tended to be older and had multiple hip operations previously. Only 3 (2 during Ganz and 1 during bilateral hip reconstruction) of these 6 children needed intra-operative blood transfusion. None of the under 4 years old children needed intra-operative blood transfusion. We conclude that children for unilateral primary hip operations for DDH do not need pre operative blood cross match. A group and save is enough in these cases

Background. One-stage bilateral total hip arthroplasty (THA) is twice as invasive as unilateral THA. Therefore, increases in bleeding, postoperative anemia, and complications are a concern. The purpose of this study was to investigate hemoglobin values and the use of autologous and allogenic blood transfusion after one-stage bilateral THA. Methods. Twenty-nine patients (7 men and 22 women; 58 hips) were treated with one-stage bilateral THA. The mean age of subjects at the time of surgery was 60.6 years. The average body mass index for patients was 21.7 kg/m. 2. The diagnoses were secondary osteoarthritis due to developmental dysplasia of the hip (n=25) and avascular necrosis (n=4). All patients had donated 800 ml of autologous blood in 2 stages preoperatively (1 to 4 weeks apart). All patients took iron supplements starting from 5 weeks preoperatively. For all patients, the procedure was performed under general anesthesia in the lateral decubitus position via a posterolateral approach. Intra-operative blood salvage was not used. Suction drains were inserted subfascially. As a general rule, pre-donated autologous blood was transfused back to the patients intra- or post-operatively. Allogenic blood transfusion was performed when clinical symptoms of anemia occurred (hypotension, low urinary output, tachycardia, etc.) rather than using a preset blood threshold (hemoglobin level <8 g/dl). To determine changes in blood pressure following surgery until the next morning, systolic and diastolic blood pressure were measured at 3-hr intervals. Results. The mean duration of surgery was 67.4 min for the procedure on the side that was operated on first, 32.7 min to change to the other side, and 68.4 min for the procedure on the other side. The mean blood loss was 576.1 ml. Hemoglobin values at baseline, at the time of autologous blood donation, and on the first day after surgery were 13.2, 12.7, and 8.7 g/dl respectively. Hemoglobin values were significantly different between the 2 weeks before surgery and the first day after surgery. Systolic and diastolic blood pressure were the lowest 3–6 hrs postoperatively (mean, 86/55). Blood reinfusion using autologous blood was performed for all patients. The allogenic blood transfusion rate was 25.0% (range, 2–8 units). In terms of complications, one patient developed an arrhythmia on postoperative day 5. This was the patient for whom autologous blood donation could not be performed due to pre-existing anemia. This patient also had right-sided sciatic nerve palsy. Discussion. With respect to one-stage bilateral THA, Gie showed that allogenic blood transfusion rate with or without autologous blood donation was 42% and 87% respectively. The allogenic blood transfusion rate was 25.0% in our study. Establishing a procedure to perform surgery in a shorter time period may further reduce the rate of allogenic blood transfusion. Although not used herein, intraoperative blood salvage may also be considered. Conclusions. In one-stage bilateral THA, autologous blood donation is effective in managing perioperative anemia and reducing the rate of allogenic blood transfusion. Perioperative blood management based on individual patients' situations are important for the safe performance of one-stage bilateral THA

Introduction. Distal femur fractures have traditionally been stabilized with either lateral locking plate or retrograde intramedullary nail. Dual-plates and nail-plate combination fixation have the theoretical biomechanical advantage, faster union and allows patients to weight bear immediately. The aim of this study is to compare single vs combination fixation, and evaluate outcomes and complications. Method. We retrospectively reviewed all patients over 60, admitted to Christchurch Hospital, between 1st Jan 2016 and 31st Dec 2022, with an AO 33A/33B/33C distal femur fracture. Patient demographics, fracture characteristics, operation details, and follow up data were recorded. Primary outcomes are union rate, ambulatory status at discharge, and surgical complications. Secondary outcomes include quality of reduction, operation time and rate of blood transfusions. Results. 114 patients were included. (92 single fixation, 22 combination fixation). Baseline demographic data and fracture characteristics did not differ between the cohorts. There was no difference in the rate of union or time to union between the two cohorts. Combination fixation patients were allowed to weight-bear as tolerated significantly more than single fixation patients (50% vs 18.9%, p=0.003). There was no difference in length of hospital stay, transfusion, complication and mortality rates. Medial translation of the distal articular block was significantly lower in the combination fixation cohort (1.2% vs 3.4%, p=0.021). Operation time was significantly longer in the combination fixation cohort (183mins vs 134mins, p<0.001). Discussion. The results show no difference in achieving union or time to union, despite better quality of fracture reduction with dual fixation. This differs to previously published literature. The clear benefit of combination fixation is immediate weight-bearing. As expected, operation times were longer with combination fixation, however this did not translate to more complications. Conclusion. Combination fixation allows earlier weight bearing, at the cost of longer operation times

Abstract. Introduction. There is paucity of evidence in predicting outcomes following cervical decompression in patients in octogenerians with cervical myelopathy. Our aim is to analyse the predictive value of Charlson comorbidity index (CCI) on clinical outcomes in this group. Methods. All patients age >80 years who underwent cervical decompression+/−stabilisation between January 2006-December 2021 at University Hospitals of Derby & Burton were included. Logistic regression analysis was performed using JASP. Results. Total 72 patients (n=32 male, n=28 female). Mean age 83.44 ± 3.21 years. 67 patients underwent posterior decompression+ stabilisation & 5 patients had posterior decompression alone. Mean CCI was 5; graded moderate in 32 (44%, CCI=<4) and severe in 40 (55.5%, CCI>4). Mean age and preoperative Nurick grade was similar between moderate and severe groups. Postoperative Nurick grade improved equally in both groups by 0.67 and 0.68 respectively (p=0.403). Mean LOS 16±16.12 days. 5 complications in the moderate group (21.8%) and 8 complications in severe group (21.6%); wound infection (n=7), other infection (n=2), electrolyte derangement (n=2), AKI (n=1), blood transfusion (n=1) and early death (n=3) (p=0.752). 1 early postoperative death <30 days occurred in the moderate group (4.3%) whereas 2 occurred in the severe group (5.3%) (p=0.984). No patients with moderate CCI required nursing home discharge whereas 7.9% of severe patients required this. Conclusion. Both groups benefitted from neurological improvement postoperatively, low 1 year mortality. No difference in hospital stay, complication rate and early mortality between both groups. More patients with severe CCI require nursing care after discharge than those with moderate CCI

To compare the efficacy of intra-articular and intravenous modes of administration of tranexamic acid in primary Total Knee Arthroplasty in terms of blood loss and fall in haemoglobin level. This randomized controlled trial was conducted from 12th May 2017 to 11th May 2017. Seventy eight patients were included in the study. Patients were randomly divided into group A and B. Group A patients undergoing unilateral primary total knee replacement (TKR) were given intravenous tranexamic acid (TXA) while group B were infiltrated with intra-articular TXA. Volume of drain output, fall in haemoglobin (Hb) level and need for blood transfusion were measured immediately after surgery and at 12 and 24 hours post operatively in both groups. The study included 35 (44.87%) male and 43 (55.13%) female patients. Mean age of patients was 61±6.59 years. The mean drain output calculated immediately after surgery in group A was 45.38±20.75 mL compared with 47.95±23.86 mL in group B (p=0.73). 24 hours post operatively, mean drain output was 263.21±38.50 mL in intravenous group versus 243.59±70.73 mL in intra-articular group (p=0.46). Regarding fall in Hb level, both groups showed no significant difference (p>0.05). 12.82% (n=5) patients in group A compared to 10.26% (n=4) patients required blood transfusion post operatively (p=0.72). Intra-articular and intravenous TXA are equally effective in patients undergoing primary total knee arthroplasty in reducing post operative blood loss.

The aim of this study was to determine the incidence, annual trend, perioperative outcomes, and identify risk factors of early-onset (≤ 90 days) deep surgical site infection (SSI) following primary total knee arthroplasty (TKA) for osteoarthritis. Risk factors for early-onset deep SSI were assessed. We performed a retrospective population-based cohort study using prospectively collected patient-level data from several provincial administrative data repositories between January 2013, and March 2020. The diagnosis of early-onset deep SSI was based on published Centre for Disease Control/National Healthcare Safety Network (CDC/NHSN) definitions. The Mann-Kendall Trend Test was used to detect monotonic trends in early-onset deep SSI rates over time. The effects of various patient and surgical risk factors for early-onset deep SSI were analyzed using multiple logistic regression. Secondary outcomes were 90-day mortality and 90-day readmission. A total of 20,580 patients underwent primary TKA for osteoarthritis. Forty patients had a confirmed deep SSI within 90-days of surgery representing a cumulative incidence of 0.19%. The annual infection rate did not change over the 7-year study period (p = 0.879). Risk factors associated with early-onset deep SSI included blood transfusions (OR, 3.93 [95% CI 1.34-9.20]; p=0.004), drug or alcohol abuse (OR, 4.91 [95% CI 1.85-10.93]; p<0.001), and surgeon volume less than 30 TKA per year (OR, 4.45 [1.07-12.43]; p=0.013). Early-onset deep SSI was not associated with 90-days mortality (OR, 11.68 [0.09-90-58]; p=0.217), but was associated with an increased chance of 90-day readmission (OR, 50.78 [26.47-102.02]; p<0.001). This study establishes a reliable baseline infection rate for early-onset deep SSI after TKA for osteoarthritis through the use of a robust methodological process. Several risk factors for early-onset deep SSI are potentially modifiable or can be optimized prior to surgery and be effective in reducing the incidence of early-onset SSI. This could guide the formulation of provincial screening programs and identify patients at high risk for SSI

Introduction. Total knee replacements (TKR) are among the commonest operations performed in orthopaedic practice. Literature review showed that 10-30% of patients who underwent TKR needed 1-3 units of blood. Tranexamic acid (TXA) has been popularised as an effective way to reduce blood loss and subsequent blood transfusion. Our aim was to investigate the value of TXA in reducing blood loss and blood transfusion after TKR and other clinical outcomes such as deep venous thrombosis (DVT), pulmonary embolism (PE), ischaemic heart diseases and mortality. Patients and Methods. A systematic review and meta-analysis of published randomised and quasi-randomised trials which used TXA to reduce blood loss in knee arthroplasty were conducted. Results. 18 clinical trials were considered suitable for detailed data extraction. There were no trials which utilised TXA in revision TKR. Blood loss. Fourteen studies (885 patients) were eligible for this outcome. Using TXA significantly reduced postoperative blood loss by an average of 203.64.65 ml (P-value <0.00001, 95% CI -177.44-229.84, I2 =89 %) and total blood loss by an average of 591.44 ml (P-value <0.00001, 95% CI -646.82-536.06, I2 =78 %). Blood transfusion. Sixteen studies (1085 patients) were eligible to measure the effect of TXA on blood transfusion after TKR. TXA led to a reduction in the proportion of patients who required blood transfusion (RD -0.34, P-value <0.00001, 95% CI -0.38-0.29, I2 =65). Other outcomes. There were no significant differences in the length of hospital stay, DVT, PE, mortality, wound haematoma or infections between the study groups. Conclusion. TXA appears effective and safe in reducing blood loss and allogeneic blood transfusion in primary TKR

Total hip and knee arthroplasty is known to have a significant blood loss averaging 3–4 g/dL. Historically, transfusion rates have been as high as 70%. Despite years of work to optimise blood management, some published data suggests that transfusion rates (especially with allogeneic blood) are rising. There is wide variability between surgeons as well, suggesting that varying protocols can influence transfusion rates. Multiple studies now associate blood transfusions with negative outcomes including increased surgical site infection, costs, and length of stay. Preoperative measures can be employed. Identify patients that are at increased risk of blood transfusion. Smaller stature female patients, have pre-operative anemia (Hgb less than 13.0 gm/dl), or are undergoing revision or bilateral surgery are at high risk. We identify these patients and check a hemoglobin preoperatively, using a non-invasive finger monitor for screening. For anemic patients, iron administration (oral or IV) can be given, along with Procrit/Epogen in select cases. Insurance coverage for that medication has been challenging. Intraoperative measures that have been linked to reduced postoperative transfusions include regional anesthesia and intraoperative hypotension (mean arterial pressure <60mm/hg). Lowering the surgical time by practicing efficient, organised, and quality surgery, along with leaving a dry field at the completion of surgery can reduce blood loss. Tranexemic acid (TXA) is an antifibrinolytic agent that has been shown to be effective, reducing average blood loss by 300 cc per case. There are multiple different administration protocols: IV using either a weight-based dosing 10–20 mg/kg or standardised dosing for all patients. Our current regimen is 1 gm IV preoperatively, 1 gm IV in PACU. Topical TXA can be used, usually 2–3 gm mixed in 50–100 cc of saline, sprayed in wound and allow to soak for 3–5 minutes. Oral administration is attractive for ease of use and reduced cost, standard oral dosing is 1950 mg PO 2 hours prior to surgery. The American Association of Hip and Knee Surgeons, in collaboration with the American Association of Orthopedic Surgeons, American Society of Regional Anesthesiologists, and the Hip & Knee Society have developed a Clinical Practice Guideline with 8 recommendations for TXA as follows: All individual formulations are effective at reducing blood loss – strong; No method of administration is clearly superior at reducing blood loss and the risk of transfusion; The dose of IV or topical TXA does not significantly affect the drug's ability to reduce blood loss and risk of transfusion; Multiple doses of IV or oral TXA compared to a single dose does not significantly alter the risk of blood transfusion; Pre-incision IV TXA administration potentially reduces blood loss and risk of transfusion compared to post-incision administration; Administration of all TXA formulations in patients without history of VTE does not increase the risk of VTE; Administration of all TXA formulations in patients with a history of VTE, MI, CVA, TIA, or vascular stent does not appear to increase the risk of VTE; Administration of all TXA formulations does not appear to increase the risk of arterial thrombotic events; Postoperative measures to reduce transfusion rates include changing transfusion triggers. Instead of treating a “number”, use lower thresholds and employ safe algorithms established. In conclusion, a comprehensive blood management program can reduce transfusion rates to less than 3% for THA and 1% for TKA and facilitate outpatient total joint arthroplasty
