The rate of homologous blood transfusion (HBT) following primary total hip replacement (THR) can be as high as 30–40% and is not without risk. Postoperative blood salvage (POS) with
Clinical, haematological or economic benefits of post-operative blood salvage with autologous blood re-transfusion have yet to be clearly demonstrated for primary total hip replacement. We performed a prospective randomised study to analyse differences in postoperative haemoglobin levels and homologous blood requirements in two groups of patients undergoing primary total hip replacement. A series of 158 patients was studied. In one group two vacuum drains were used and in the other the ABTrans

We studied the use of autologous pre-donated blood transfusion in surgery for scoliosis in 45 patients who were divided into two groups; 27 who pre-donated autologous blood (group 1) and 18 who were planned recipients of allogenic blood (group 2). Normovolaemic haemodilution and intra-operative blood salvage was used in six patients in group 1 and three patients in group 2. The two groups did not differ significantly with respect to age, American Society of Anaesthesiologists score, mean operative time, number of vertebral segments fused, total blood loss, length of stay in intensive care and length of stay in hospital. The risk of requiring allogenic blood transfusion was found to be significantly less in group 1 (7.4% ν 88.9%, p <
0.001). Only 5.21% of autologous units were wasted. Although intra-operative blood salvage reduced the total blood loss in both groups, it did not affect the need for subsequent allogenic transfusion or reduce the number of pre-donated autologous units which were given (p <
0.67).

Intra-operative, peri-articular injection of
local anaesthesia is an increasingly popular way of controlling
pain following total knee replacement. The evidence from this study suggests that it is safe to use
peri-articular injection in combination with auto-transfusion of
blood from peri-articular drains during knee replacement surgery.
There is currently no consensus about the mean
volume of blood lost during spinal tumour surgery and surgery for metastatic
spinal disease. We conducted a systematic review of papers published
in the English language between 31 January 1992 and 31 January 2012.
Only papers that clearly presented blood loss data in spinal surgery
for metastatic disease were included. The random effects model was
used to obtain the pooled estimate of mean blood loss. We selected 18 papers, including six case series, ten retrospective
reviews and two prospective studies. Altogether, there were 760
patients who had undergone spinal tumour surgery and surgery for
metastatic spinal disease. The pooled estimate of peri-operative
blood loss was 2180 ml (95% confidence interval 1805 to 2554) with catastrophic
blood loss as high as 5000 ml, which is rare. Aside from two studies
that reported large amounts of mean blood loss (>
5500 ml), the
resulting funnel plot suggested an absence of publication bias.
This was confirmed by Egger’s test, which did not show any small-study
effects
(p = 0.119). However, there was strong evidence of heterogeneity
between studies (I2 = 90%; p <
0.001). Spinal surgery for metastatic disease is associated with significant
blood loss and the possibility of catastrophic blood loss. There
is a need to establish standardised methods of calculating and reporting
this blood loss. Analysis should include assessment by area of the
spine, primary pathology and nature of surgery so that the amount
of blood loss can be predicted. Consideration should be given to
autotransfusion in these patients. Cite this article:

Background: Autologous blood from reinfusion drains are commonly used after major joint arthroplasties with a view to decrease the heterologous blood transfusion requirement. The aim of this study is to find the effect of reinfusion drains on the difference in haemoglobin (Hb) level before and after total knee arthroplasties. Material and Methods: Between January 2001 and October 2003, 158 patients had total knee arthroplasty on one side. The type of thromboprophylaxis used was the same in all the patients. 74 patients had
We undertook a prospective, randomised study in order to evaluate the efficacy of clamping the drains after intra-articular injection of saline with 1:500 000 adrenaline compared with post-operative blood salvage in reducing blood loss in 212 total knee arthroplasties. The mean post-operative drained blood volume after drain clamping was 352.1 ml compared to 662.3 ml after blood salvage (p <
0.0001). Allogenic blood transfusion was needed in one patient in the drain group and for three in the blood salvage group. Drain clamping with intra-articular injection of saline with adrenaline is more effective than post-operative
Purpose: The purpose of this study was to use the thromboelastogram to determine whether
Introduction: Elective joint replacement patients routinely require transfusion following surgery. Haemoglobin must remain within red blood cells in order to be functional. The process of surgery and collection in the reinfusion drain may disrupt cell membranes resulting in non functional haemoglobin. The filtration and collection process does not eliminate free haemoglobin. This results in intracellular and free haemoglobin being transfused into patients giving false functional haemoglobin levels. Aim: To determine the proportion of intracellular haemoglobin in
Introduction: Total knee replacement commonly results in postoperative requirement of blood transfusion. Allogeneic blood transfusion carries transfusion related risks, continuing effort to reduce allogeneic blood transfusion is important. The purpose of this study was to asses the economic justification of the use of an

Introduction: A prospective analysis of the total blood losses (TBL) and the rate of blood transfusions was conducted for the unilateral primary TKA performed at our clinic from January 2008 to March 2009. A transfusion-sparing strategy was used, based on the use of the tourniquet, the intraoperative injection of tranexamic acid and the preoperative administration of erythropoietin for patients with hemoglobin baseline level less than 13 gr/dl. The formula of Gross and the values of Gilcher were utilized to calculate TBL and to estimate the blood volume of the patient. No

The entirety of the patient experience after contemporary total knee and total hip replacements in 2017 is markedly different from that encountered by patients just a decade ago. Ten years ago most patients were treated in a traditional sick-patient model of care and because they were assumed to require substantial hospital intervention, many cumbersome and costly interventions (e.g. indwelling urinary catheters, patient-controlled-analgesic pumps,
