Prompt mobilisation after the Fracture neck of femur surgery is one of the important key performance index (‘KPI caterpillar charts’ 2021) affecting the overall functional outcome and mortality. Better control of peri-operative blood pressure and minimal alteration of renal profile as a result of surgery and anaesthesia may have an implication on early post-operative mobilisation. Aim was to evaluate perioperative blood pressure measurements (duration of fall of systolic BP below the critical level of 90mmHg) and effect on the post-operative renal profile with the newer short acting spinal anaesthetic agent (prilocaine and chlorprocaine) used alongside the commonly used regional nerve block. 20 patients were randomly selected who were given the newer short acting spinal anaesthetic agent along with a regional nerve block between May 2019 and February 2020. Anaesthetic charts were reviewed from all patients for data collection. The assessment criteria for perioperative hypotension: Duration of systolic blood pressure less than 90 mm of Hg and change of pre and post operative renal functions. Only one patient had a significant drop in systolic BP less than 90mmHg (25 minutes). 3 other patients had a momentary fall of systolic BP of less than 5 minutes. None of the above patients had mortality and had negligible change in pre and post op renal function. Only one patient in this cohort had elevation of post-operative creatinine levels but did not have any mortality. Only 1 patient died on day 3 post operatively who had multiple comorbidities and was under evaluation for GI cancer. Even in this patient the peri-operative blood pressure was well maintained (never below 90mmHg systolic) and post-operative renal function was also shown to have improved (309 pre-operatively to 150 post-operatively) in this patient. The use of short-acting spinal anaesthesia has shown to be associated with a better control of blood pressure and end organ perfusion, less adverse effects on renal function leading to early mobilisation and a more favourable patient outcome with reduced mortality, earlier mobilisation, shorter hospital stay and earlier discharge in this elderly patient cohort

Introduction. Despite recent national advances in the care for the hip fracture patient, significant morbidity and mortality persists. Some of this morbidity is attributable to the analgesia provided in the hospital setting. The National Institute of Clinical Excellence recommends the use of simple oral analgesia including opioids, with fascia-iliac blocks used as an adjunct. Literature review reveals a paucity of evidence on this topic. The aim of this study was to evaluate the efficacy of fascia iliac blocks through analysis of pre and post-operative opioid usage, post-operative delirium, time to bowel opening and naloxone use. Methods. A retrospective study was performed between September-December 2013. Inclusion criteria were determined. 41 patients who received spinal anaesthesia alone and 41 patients who received spinal anaesthesia and a fascia-iliac block were included. Results. Patients who received a fascia-iliac block received significantly less post-operative and total analgesia (p=0.04, p=0.03), had lower rates of delirium (p=0.03) and those patients which were discharged directly home had a shorter inpatient stay (p=0.03). No patients who received a fascia-iliac block needed naloxone to reverse opioid toxicity, whilst two non fascia iliac block patients did. Conclusions. Fascia iliac blocks either given in A&E or at the time of spinal anaesthesia are a useful adjunct to provide analgesia in the hip fracture patient. The John Radcliffe hospital aims to incorporate fascia-iliac blocks into the care pathway for the hip fracture patient

Background. Adequate pain management is mandatory for patients' early rehabilitation and improvement of outcome after total knee arthroplasty (TKA). Conventional pain management, consisted of mainly opioids, has some adverse effects such as dizziness and nausea. Motor blockade occasionally resulted from epidural analgesics. A novel multimodal analgesic strategy with peripheral nerve block, peri-articular injection (PAI) and intravenous patient controlled analgesia (IVPCA) were utilized for our patients receiving TKA. In this study, we compared the clinical efficacy and adverse effects in the group of multimodal analgesia (MA) or epidural analgesia alone. Methods. One hundred and eighteen patients undergoing TKA with spinal anesthesia were enrolled. Patients of TKA received either our protocol of multimodal analgesia or patient controlled epidural analgesia (PCEA) alone. MA included ultrasound guided nerve block in femoral and obturator nerves before spinal anesthesia, and PAI mixed with NSAID, morphine, ropivacaine and epinephrine, as well as IVPCA after surgeries. The analgesic effect with numeric rating scale (NRS) and occurrence of adverse effects, including motor blockade, numbness, postoperative nausea/vomiting (PONV), and dizziness were recorded for all patients. Results. Thirty-one patients received MA, and eighty-seven patients received PCEA. No significant difference of NRS in MA and PCEA group within 24 hours after surgery either in rest (0.2 ± 1 compared with 0.22 ± 0.98; p = 0.930) or motion (0.40 ± 1.56 compared with 0.31± 1.23; p = 0.764). MA group sustained lesser motor blockade than PCEA (6.45% compared with 22.98%; p = 0.028) beyond 24 hours after surgery. The occurrence of numbness is lower in MA group (18.52%) compared with PCEA group(43.33%) (p=0.031). No statistic difference of PONV and dizziness is noted between two groups. However, there is a trend that lesser PONV and dizziness occurred in MA group than PCEA group. Conclusion. TKA patients receiving either MA or PCEA have adequate analgesic efficacy after surgeries. MA group has a lower incidence of motor blockade and PONV than PCEA. This multimodal analgesia proposed here has shown patients' safety and improved pain control after TKA, decreased narcotics use and their associated side effects. Besides, lesser motor blockade and adequate pain relief may encourage patient's early rehabilitation

Introduction and Objective. Osteoarthritis of the knee joint is common in old age population in every part of world. Pain is the major source of disability in patients with osteoarthritis of the knee joint. Subchondral bone marrow is richly innervated with nociceptive pain fibers and may be a source of pain in patients with symptomatic degenerative joint disease. Current therapy for managing bone marrow oedema is core decompression (CD), combining core decompression and injection of hydroxyapatite cement or autologus chondrocyte supplementtion. But all of this work has been done in femoral head and authors documented good result with minimal complication. There are various studies in literature suggesting treatment to repair BME by restoring support and relieving abnormal stresses with accepted internal fixation and bone stimulating surgical techniques in relieving knee OA pain. In this study, we present efficacy of knee arthroscopy with adjunctive core decompression and supplementation with structural scaffold to improve self-rated visual analog scale (VAS) pain scores, rate of conversion to arthroplasty, and patient satisfaction levels. Materials and Methods. The study included patients aged between 40 and 75 years old, with pain in the knee for at least six months, associated with high-signal MRI lesion on T2 sequences, on the tibia or femur. Trephine was used as the bone decompression instrument. Trephine has a diameter of 8–10 mm and operation with trephine requires that a cortical incision window be made prior to decompression treatment, thus necessitating strict disinfection. This procedure was done under spinal anesthesia. After diagnostic arthroscopy, decompression was done under C –ARM in desired area on MRI. After decompression, defect was filled with Poly ester urea's scaffold impregnated with BMAC. Results. Patients were assessed using the visual analog pain scale and the KOOS score, one week before surgery and one, three, six, 12, and 24 weeks after the procedure. MRI images were analyzed Lesions were mapped and measured in the axial, coronal, and sagittal views to plan the injection site and the trajectory of the cannula used for the procedure. Radiographs using anteroposterior, profile, and Rosenberg views of the knee and lower limb were performed to classify the lesion according to the Kellgren-Lawrence classification and to assess lower limb alignment. Evaluation using the KOOS showed a mean total score in the preoperative period of 38.44 points and of 60.7, 59.08, 56.92, 64.40, and 71.36 points at one, three, six, 12, and 24 weeks after surgery, respectively. In the VAS assessment, mean was 7.8 points preoperatively and 2.8, 2.6, 2.5, 1.3, and 0.5 points in the same periods. Conclusions. Hence it can be Concluded that this new innovative technique has provided significant improvements in the parameters of pain and functional capacity in the short-term assessment

Background. Acute pain following total knee replacements (TKRs) is associated with higher peri-operative opiate requirements and their side effects, longer hospital stay and lower patient satisfaction (Petersen 2014). It may also be associated with higher rates of chronic pain at 1 and 5 years (Beswick 2012). We present a novel technique using combination of Local Infiltration Anaesthesia (LIA) with PainKwell infusion system (Bupivacaine 0.5 @ 4mls and 6mls/hr) to improve pain management following TKRs. Methods. Between October 2015 and March 2016. 110 patients undergoing primary TKR were prospectively studied. All patients studied had spinal anaesthesia (SA) with diamorphine. Demographics between the two groups were similar. Group 1. SA plus LIA plus traditional multimodal analgesia. 32 patients. Group 2. SA plus LIA plus PainKwell for 48 hours rate 4mls. 38 patients. Group 3. SA plus LIA plus PainKwell for 48 hours rate 6mls. 40 patients. Results. Visual analogue pain scores demonstrated a significant difference at 8hrs, 12hrs, 24hrs and 48hrs between group 1 and 3; p<0.05. There was also a statistical difference in opiate usage at 24 hours between the three groups with group 3 using significantly less opiates compared to group 1. There was least consumption of opiates in group 3 patients across all study periods. Conclusions. This study reported that SA plus LIA and PainKwell system was effective in reducing pain following TKRs. It also demonstrated that the technique of SA plus LIA plus PainKwell for 48 hours at a rate 6mls/hr reduced opiate usage by 50% and pain by 30% for these patients. Implications. This technique may help improve rehabilitation and shorten hospital stay following total knee arthroplasties

Background. Pain control following knee replacement (TKR) surgery is often poor. Moderate to severe pain is often reported in the first 48 hours following surgery requiring opiate analgesia. The Local Infiltration Anaesthetic (LIA) technique has been described as a method to reduce post operative pain. In this study we report on our experience using LIA in addition to the PainKwell system (Peak Medical) of continuous infusion intra-articularly, of 0.25% bupivacaine at 4–5 mls/hour for 48 hours post surgery. The PainKwell catheter is placed in the knee joint during surgery. Methods. Between the June 2012 and Sep 2012, 62 patients undergoing primary TKR were prospectively followed up. All patients studied had spinal anaesthesia (SA) with diamorphine. Group 1. GA. No LIA and no PainKwell. 20 patients. Group 2. SA plus LIA plus PainKwell for 48 hours post operatively with catheter placed anteriorly under the patella. 21 patients. Group 3. SA plus LIA plus PainKwell for 48 hours post operatively with catheter placed posteriorly in the knee joint. 21 patients. Results. The patients without LIA or PainKwell required more morphine in the first 12 hours postoperative period than the other groups. Seventy percent (n=14) of these group 1 patients required 10mg morphine following TKR compared to only 2% (n=1) of patients requiring 10mg of morphine when LIA and PainKwell as used. The increased morphine requirement continued for 48 hours postoperatively in group 1, whereas none of the patients in groups 2 or 3 required morphine after 36 hours. Fewer patients suffered from nausea and vomiting or urinary retention in the group with LIA and PainKwell

Patients undergoing total knee arthroplasty (TKA) experience significant post-operative pain. We report the results of a new comprehensive patient care plan to manage peri-operative pain, enable early mobilisation and reduce length of hospital stay in TKA. A prospective audit of 1081 patients undergoing primary TKA during 2008 and 2009 was completed. All patients followed a planned programme including pre-operative patient education, pre-emptive analgesia, spinal/epidural anaesthesia with propofol sedation, intra-articular soft tissue wound infiltration, post-operative high volume intermittent ropivacaine boluses with an intra-articular catheter and early mobilisation. The primary outcome measure was the day of discharge from hospital. Secondary outcomes were verbal rating pain scores on movement, time to first mobilisation, nausea and vomiting scores, urinary catheterisation for retention, need for rescue analgesia, maximum flexion at discharge and six weeks post-operatively, and Oxford score improvement. The median day of discharge to home was post-operative day four. Median pain score on mobilisation was three for first post-operative night, day one and day two. 35% of patients ambulated on the day of surgery and 95% of patients within 24 hours. 79% patients experienced no nausea or vomiting. Catheterisation rate was 6.9%. Rescue analgesia was required in 5% of cases. Median maximum flexion was 85° on discharge and 93° at six weeks post-operatively. Only 6.6% of patients had a reduction in maximum flexion (loss of more than 5°) at six weeks. Median Oxford score had improved from 42 pre-operatively to 27 at six weeks post-operatively. The infection rate was 0.7% and the DVT and PTE rates were 0.6% and 0.5% respectively. This multidisciplinary approach provides satisfactory post-operative analgesia allowing early safe ambulation and discharge from hospital. Anticipated problems did not arise, with early discharge not being detrimental to flexion achieved at six weeks and infection rates not increasing with the use of intra-articular catheters

Objectives

We have increased the dose of tranexamic acid (TXA) in our enhanced total joint recovery protocol at our institution from 15 mg/kg to 30 mg/kg (maximum 2.5 g) as a single, intravenous (IV) dose. We report the clinical effect of this dosage change.
