Clinical Trial Summary

Postoperative nausea and vomiting(PONV) refers to at least one nausea, retching or vomiting after operation, or any combination of the above symptoms. The incidence of PONV in high-risk patients can reach 61%-79%. PONV can not only cause dizziness and headache, but also cause disturbance of acid-base balance of water and electrolyte, wound dehiscence, formation of incisional hernia, aspiration, and aspiration pneumonia, leading to prolonged hospitalization, increased medical expenses, and reduced surgical satisfaction. At present, the guidelines for prevention and treatment of PONV and the consensus of experts suggest that identifying high-risk patients according to Apfel risk score ≥3 points, reducing baseline PONV risks, and implementing multimodal PONV prophylaxis. However, the incidence of PONV in high-risk patients is still as high as 20% even if 2-3 drugs are combined used for prevention and treatment. It is difficult to further reduce the incidence of PONV by adding different kinds or dosages of drugs, while drug-related side effects are increasing gradually. Acupuncture (electroacupuncture, transcutaneous electrical acupoint stimulationTEAS, transcutaneous electrical nerve stimulation, etc.) is a safe, effective, non-toxic side-effect non-drug treatment method. A large number of studies have confirmed that acupuncture can reduce the incidence of PONV, and it is expected to become an important supplement to drug treatment of PONV, but there are quality defects such as small sample size, inaccurate intervention and so on. At the same time, most acupuncture studies aim to compare the efficacy of PONV with drug therapy, without considering the clinical situation, using acupuncture treatment based on drug standard treatment to further reduce the incidence of PONV, thus limiting the clinical application value of acupuncture. On the basis of standardized drug prevention and treatment of PONV, TEAS will be used to further reduce the incidence of PONV and promote rapid recovery of patients. This study will strongly demonstrate that acupuncture can break through the bottleneck of drug treatment and provide evidence for the application of acupuncture in modern perioperative clinical medicine.


Description:

This study intends to carry out a high-quality clinical research with design specifications, large sample, multi-center, evaluator blinded, randomized and controlled methods. From September 1, 2019 to October 30, 2020, patients undergoing laparoscopic non-gastrointestinal surgery under general anesthesia will be recruited, based on the combination of dexamethasone and 5-HT3 antagonist, the efficacy of TEAS stimulation Neiguan (P6) and Zusanli (ST36) in the prevention and treatment of PONV will be verified. In TEAS group, bilateral P6 and ST36 TEAS intervention after removal tracheal intubation and on the first day after surgery, a total of 2 times, 30 minutes each time, 2/10 Hz low frequency sparse wave, 6-9 mA. The patients will be given maximum intensity stimulation at all points during the intervention.To ensure the blindness of the evaluator, the time of evaluation will be on the afternoon of the first and the second day, and the 30 days after the operation, and three evaluations will be made. The main indicators are the incidence of PONV 24 hours after operation, and the secondary indicators are the quantitative indicators of PONV and the indicators of rapid recovery after operation.

Outcome

Type Measure Description Time frame Safety issue
Primary Incidence of PONV within 24 hours Whether or not nausea or vomiting happens 24 hours after surgery
Secondary The first nausea the time point of the first nausea. 24 hours after surgery
Secondary The first nausea's Visual Analogue Scale the Visual Analogue Scale of the first nausea : the Visual Analog Scale (VAS) is a 10 cm line with anchor statements ,on the left (no nausea) and on the right (extreme nausea). The patient is asked to mark their current nausea level on the line. The examiner scores the VAS by measuring the distance in either centimeters (0 to 10) or millimeters (0 to 100) from the "no nausea" anchor point. 24 hours after surgery
Secondary The first vomiting the time point the first vomiting 24 hours after surgery
Secondary The first vomiting's Visual Analogue Scale the Visual Analogue Scale of the first vomiting : the Visual Analog Scale (VAS) is a 10 cm line with anchor statements ,on the left (no vomitting) and on the right (extreme vomiting). The patient is asked to mark their current vomiting level on the line. The examiner scores the VAS by measuring the distance in either centimeters (0 to 10) or millimeters (0 to 100) from the "no vomiting" anchor point. 24 hours after surgery
Secondary Total nausea frenquency in postoperative 24 hours the total nausea times of the subjects 24 hours after surgery
Secondary The Visual Analogue Scale of nausea in postoperative 24 hours the Visual Analogue Scale of nausea in postoperative 24 hours : the Visual Analog Scale (VAS) is a 10 cm line with anchor statements ,on the left (no nausea) and on the right (extreme nausea). The patient is asked to mark their current nausea level on the line. The examiner scores the VAS by measuring the distance in either centimeters (0 to 10) or millimeters (0 to 100) from the "no nausea" anchor point. 24 hours after surgery

The patient is asked to mark their current vomiting level on the line. The examiner scores the VAS by measuring the distance in either centimeters (0 to 10) or millimeters (0 to 100) from the "no vomiting" anchor point. 24 hours after surgery
Secondary 40-itemquality of recovery score The quality of postoperative life recovery was assessed by questionnaire.
