[Transcutaneous electrical acupoint stimulation relieves post-operative nausea and vomiting possibly by reducing serum motilin secretion in patients undergoing laparoscopic surgery].

OBJECTIVE: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) of different acupoint combinations on postoperative nausea and vomiting (PONV) and serum motilin (MTL) content in patients undergoing laparoscopic surgery, so as to provide evidence for clinical selection of suitable acupoint compatibility. METHODS: groups received TEAS (2 Hz/100 Hz, 3-8 mA) of the above mentioned acupoint (bilateral) groups for 30 min before the induction of anesthesia until the end of the operation. Patients of the GA control group received intravenous injection of Midazolam, Sufentanil, Propofol, Rocuronium Bromide, etc. The blood sample (4 mL) from the right median cubital vein was collected at the time of patient's entry, 12 and 24 h after surgery, respectively, for measuring MTL concentration by enzyme-linked immunosorbent assay. The incidence of early and late PONV and changes of PONV degree within 24 h after surgery were recorded. RESULTS: <0.05), suggesting a mild PONV in more patients undergoing TEAS. CONCLUSION: (two acupoints) group.
