摘要Background:Transvaginal oocyte retrieval is frequently followed by adverse events related to anesthesia and the procedure.Some research showed that transcutaneous electrical acupoint stimulation(TEAS)can relieve intraoperative pain and postoperative nausea.Objective:This study examined whether TEAS can alleviate pain and relieve adverse symptoms after oocyte retrieval.Design,setting,participants and interventions:Altogether 128 patients were randomly divided into the TEAS group and the mock TEAS group.The two groups received a 30-minute-long TEAS or mock TEAS treatment that began 30 min after oocyte retrieval.Main outcome measures:The primary outcome was the visual analog scale(VAS)pain score.Secondary outcomes were pressure pain threshold,McGill score,pain rating index(PRI),present pain intensity(PPI),VAS stress score,VAS anxiety score,and postoperative adverse symptoms.Results:The baseline characteristics of the two groups were comparable(P＞0.05).The VAS pain scores of the TEAS group were lower than those of the mock TEAS group at 60 and 90 min after oocyte retrieval(P＜0.05).The McGill score,PRI and PPI in the TEAS group were significantly lower than those in the con-trol group at 60 min after oocyte retrieval(P＜0.05).However,the two groups had equivalent beneficial effects regarding the negative emotions,such as nervousness and anxiety(P＞0.05).The TEAS group was superior to the mock TEAS group for relieving postoperative adverse symptoms(P＜0.05).Conclusion:TEAS treatment can relieve postoperative pain and postoperative adverse symptoms for patients undergoing oocyte retrieval.
