RESUMEN
@#Objective To analyze the efficacy of no-touch technique and traditional technique in drawing great saphenous vein during coronary artery bypass grafting. Methods We searched the literatures on no-touch technique versus traditional technique in drawing great saphenous vein during coronary artery bypass grafting in PubMed, Cochrane Library, Chinese Journal Full-text Database, Wanfang database between January 1997 and November 2017. Jadad scale was used for quality verification. RevMan 5.0 was used for analysis. Results Six studies were included. Jadad scale for both 6 randomized controlled trials was 5 points. Meta-analysis showed that there was no statistical difference in postoperative mortality between the two groups with RR=0.68 and 95%CI 0.11 to 4.11(P=0.67). There was no statistical difference in leg wounds with RR=1.46 and 95%CI 0.23 to 9.16 (P=0.68). There was no statistical difference in short-term cardiogenic death with RR=0.33, 95%CI 0.10 to 1.03 ( P=0.06). The no-touch group’s long-term cardiogenic death was significantly lower than the traditional group withRR=0.36, 95%CI 0.16 to 0.79(P=0.01). Postoperative no-touch group’s short-term patency rate was significantly better than that of the traditional group with MD=3.08 and 95%CI 1.58 to 5.99 (P<0.01). The long-term patency rate in the no-touch group was also higher than that of the traditional group withMD=3.08 and 95%CI 1.58 to 5.99 (P<0.01). Conclusion Compared with the traditional group, the no-touch group increases postoperative long-term survival rate, short-term and long-term patency rate.
