[ Effects of transcutaneous electrical stimulation of auricular Shenmen point on postoperative nausea and vomiting and patient-controlled epidural analgesia in cesarean section ] . OBJECTIVE To investigate the effects of transcutaneous electrical stimulation of auricular Shenmen point on postoperative nausea and vomiting and patient-controlled epidural analgesia in cesarean section . METHODS After IRB approval and informed consent , one hundred and eighty singleton primiparas undergoing elective cesarean section , in Qingdao Municipal Hospital , and Qingdao Hiser Medical Center , from November 2011 to March 2012 , were randomly assigned to three groups : transcutaneous electrical stimulation of auricular Shenmen point group ( group A , n = 60 ) , transcutaneous electrical stimulation of auricular Eye point group ( group B , n = 60 ) and control group ( group C , n = 60 ) . Women of group A received transcutaneous electrical stimulation of auricular Shenmen point ( frequency 1.5 HZ ) at the time of preoperation , 4 , 10 and 22 hours of postoperation for 30 minutes . The strength was controlled by themselves . Women of group B received stimulation of auricular Eye point as group A . Women of group C received pressurization and connected line were the same with group A , but without electrical stimulation . The following indexes was observed : the incidence of postoperative nausea and vomiting ( PONV ) for 48 hours ; the rate of metoclopramide ; the visual analogue scale ( VAS ) score of rest pain , uterine contration pain and dynamic pain at the time of postoperation for 6 , 12 , 24 and 48 hours ( T ( 1 ) -T ( 4 ) ) ; the total number and effective compressions number of patient-controlled epidural analgesia ( PCEA ) ; the dose of analgesia mixture ; the anal exhaust time ; the volume of postoperative bleeding for 6 hours of postoperation and the other side effects . RESULTS Compared with group B and group C , the incidence of PONV , the rate of metoclopramide , the VAS score at the time T ( 1 ) -T ( 4 ) , the total number and effective compressions number of PCEA , the ratio of the total number with effective compressions number and the dose of analgesia mixture were decreased in group A ( P < 0.05 ) , but no difference compared group B with group C ( P > 0.05 ) . The anal exhaust time and the volume of postoperative bleeding for 6 hours of postoperation were no difference in the three groups ( P > 0.05 ) . No other side effects were observed . CONCLUSION Transcutaneous electrical stimulation of auricular Shenmen point can reduce the incidence of PONV and improves analgesia effect of PCEA in postoperation of cesarean section .
