title: [Efficacy of preventing postoperative nausea and vomiting after thyroid tumor surgery by TAES at neiguan (P1): a clinical observation].
abstract: OBJECTIVE
  To observe the clinical efficacy of transcutaneous acupoint electrical stimulation (TAES) combined intravenous injection and/or Neiguan (P6) injection with droperidol in preventing and treating post-operative nausea and vomiting (PONV) after thyroid tumor surgery.
  
  
  METHODS
  Recruited were 120 female patients who underwent selective thyroid tumor surgery were randomly assigned to the control group, the TAES group, the IV group (intravenous injection of droperidol), and the P6 group [Neiguan point (P6) injection of droperidol], respectively, 30 cases in each group. Thirty min before anesthesia induction, 2 mL 0.9% normal saline injection was intravenously injected to those in the control group. Patients in the TAES group received TEAS at bilateral P6 points. 2.5 mg (1 mL) droperidol added in 1 mL 0.9 normal saline was intravenously injected to those in the IV group and injected at bilateral P6 points of those in the P6 group. The occurrence and severity of PONV were observed within 0 - 6 h and within 6 - 24 h after operation in each group.
  
  
  RESULTS
  Compared with the control group, the incidence and the severity of PONV within 0 - 6 h and within 6 - 24 h after thyroid surgery were significantly reduced in the three treatment groups (P < 0.05). There was no statistical difference in the incidence or the severity of PONV among the TAES, IV and P6 groups (P > 0.05).
  
  
  CONCLUSIONS
  TEAS at P6 could dramatically reduce the occurrence and the severity of PONV after thyroid tumor surgery. Besides, it got equivalent effect to that by intravenous injecting droperidol or by injecting droperidol at P6.
