Findings and Conclusion To our knowledge , this is the first meta- analysis to compare the clinical results between PAT and a control in joint replacement patients .
This meta- analysis has proven that the use of a PAT reinfusion system reduced significantly the dem and for ABT , the number of patients who require ABT and the cost of hospitalization after total knee and hip arthroplasty .
This study , together with other previously published data , suggests that PAT drains are beneficial .
Background Total hip or knee arthroplasty is an elective procedure that is usually accompanied by substantial blood loss , which may lead to acute anemia .
As a result , almost half of total joint arthroplasty patients receive allogeneic blood transfusions ( ABT ) .
Many studies have shown that post-operative auto-transfusion ( PAT ) significantly reduces the need for  ABT  , but other studies have question ed the efficacy of this method .
Comparative analysis of the benefits of autotransfusion of blood by a shed blood collector after total knee replacement
Introduction Joint replacement is associated with massive blood loss . Various techniques have been used to avoid the use of allogeneic blood . One of the techniques used is postoperative salvage and reinfusion of shed blood that was found to reduce the use of banked blood with its potential risk . Material s and methods We prospect ively studied 365 patients who underwent knee joint replacement ( TKR )  and were divided in two groups . Group A ’s shed blood ( SureTrans System ) was collected ( n=194 ) and reinfused and group B ’s was not ( n=171 , “ controls ” ) . Hemoglobin levels before and after the operation were recorded . Results Allogeneic blood requirement for TKR decreased by 65 % in group A compared to group B. The packed cell/patient index dropped from 0.91 to 0.29 in group 2A . Statistical analysis yielded the odds ratio for blood replacement , a “ predicting formula ” for blood replacement depending on hemoglobin levels , and a cutoff point for a patient ’s receiving blood replacement . Conclusion We recommend using this system in TKR for decreasing allogeneic blood replacement and potential associated risks . The predicting formula for blood replacement may be a helpful tool when making a decision of whether or not to use the collector system and for whom
