Efficacy of transcutaneous auricular acupoint Shenmen stimulation for relieving pain,nausea and vomiting in breast cancer patients undergoing mastectomy
Objective To observe the efficacy of transcutaneous self-controlled electrical stimulation at auricular acupoint Shenmen for relieving pain,nausea and vomiting in breast cancer patients undergoing mastectomy.Methods Eighty breast cancer patients undergoing surgical treatment in Longhua Hospital between October 2022 and March 2023 were randomly divided into ta-SMS group and control group with 40 cases in each group.Patients in ta-SMS group received 30 min electric stimulation at auricular Shenmen point before anesthesia and after entering the anesthesia recovery room,then every 3 h after returning to the ward.The heart rate(HR),mean blood pressure(MBP)and bispectral index(BIS)were recorded in both groups.The incidence of nausea and vomiting at 24,48 and 72 h after surgery were recorded in both groups.Postoperative VAS pain score,total number of analgesic pump compression and serum 5-hydroxytryptamine(5-HT)levels before and after operation were compared between the two groups.Results The incidence of nausea and vomiting in ta-SMS group was significantly lower than that in the control group within 72 h after surgery(P<0.05).There was no significant difference in VAS scores at 24,48 and 72 h between the two groups(P>0.05).The total number of patient-controlled intravenous analgesia(PCIA)compression and the total consumption of analgesics in ta-SMS group were significantly lower than those in the control group(P<0.05).There was no difference in serum 5-HT level between the two groups before operation(P>0.05);while the serum 5-HT levels in ta-SMS group were significantly lower than those in the control group at 24,48 and 72 h after surgery(P<0.05).Conclusion Transcutaneous electrical stimulation at auricular acupoint Shenmen can reduce the incidence of nausea and vomiting after breast cancer surgery and relieve patients'pain,which are associated with the down-regulation of 5-HT.
