RESUMEN
Objective To evaluate the effect of acupuncture combined nerve block for surgery using meta-analysis.Methods We searched the data of randomized controlled trial (RCT) in Pubmed,Cochrane library,Embase,CNKI,VIP and Wanfang from the construction of database to May 2017.All RCTs that met the standards of acupuncture combined nerve block for patients undergoing surgery were collected.The meta-analysis was performed by Review Manager 5.3.Results Five trials containing 382 patients were included in this meta-analysis.Compared with nerve block alone,the pooled data showed that acupuncture combined nerve block reduced the fluctuation of intraoperative blood pressure (MD=-13.62,95％CI-15.41--11.84,P＜0.001) and heart rate (MD=-6.49,95％CI-8.61--2.36,P＜0.001),and VAS scores 8 h (MD=-1.07,95％CI -1.38--0.75,P＜0.001),12 h (MD=-1.11,95％CI-1.30--0.93,P＜0.001) and 24 h (MD=-0.15,95％ CI-0.25--0.04,P =0.006) after operation in the experimental group.Conclusion Acupuncture combined nerve block possibly improves the hemodynamic parameters and postoperative pain of patients undergoing surgery.
