A meta-analysis on the efficacy and safety of autologous drainage blood reinfusion in total knee arthroplasty / 实用医学杂志

ABSTRACT

Objective To assess the efficacy and safety of autologous drainage blood reinfusion in total knee arthroplasty(TKA). Methods Computers were used to search the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and VIP. The randomized controlled trials (RCTs) of autologous drainage blood reinfusion and vacuum suction without reinfusion after TKA were collected. And the results were analyzed by using the software RevMan5.1. Results Eight RCTs met the criteria for meta-analysis. Use of autologous drainage blood reinfusion significantly reduced the average amount of units of homologous blood transfusion, the length of hospital stay, and the number of patients requiring homologous blood transfusion. The rates of DVT formation and incision infection did not differ significantly between the two groups. Conclusions Autologous drainage blood reinfusion is a safe, effective procedure with less blood transfusion and medical cost. It can lower volume of allogeneic blood transfusion , shorten length of hospital stay, and avoid occurrence of complications.
