A meta-analysis of pneumatic tourniquet used in total knee arthroplasty / 中国组织工程研究

ABSTRACT

BACKGROUND: Pneumatic tourniquet can reduce the amount of bleeding during operation, but simultaneously, pneumatic tourniquet will bring perioperative adverse reactions. It is still controversial whether to use a pneumatic tourniquet during total knee arthroplasty. OBJECTIVE: To evaluate the effect and safety of pneumatic tourniquet in total knee arthroplasty. METHODS: We searched PUBMED, EMBASE, the Cochrane Library, CNKI, Wanfang before July 2017 for randomized controlled trials regarding the effect of pneumatic tourniquet in total knee arthroplasty. Data were extracted and analyzed by using Revman 5.3 software.RESULTS AND CONCLUSION: Totally 18 studies were included. Meta-analysis suggested that the use of pneumatic tourniquet could reduce the total amount of blood loss in the total knee arthroplasty, shorten operation time, but could increase postoperative pain and thrombosis incidence (P < 0.05). There was no statistically significant difference in HSS score and range of motion of the knee at 7 days after operation (P > 0.05). These results confirm that the use of a pneumatic tourniquet in total knee arthroplasty can reduce the total blood loss, shorten the operation time, but have no effect on knee function 7 days after total knee arthroplasty, but will increase postoperative pain and thrombosis incidence.
