Brief summary
Postoperative nausea and vomiting (PONV) is particularly one of the most common complications after laparoscopic sleeve gastrectomy (LSG). It can lead to serious adverse events and delayed activity, and prolong the time of rehabilitation and discharge. Numbers of studies have been focused on identifying risk factors and therapies of PONV. Unfortunately, there' no consistent comments for PONV prevention in women after LSG. Notably, Zusanli (ST36) acupoint and anisodamine have been evidenced to treat various gastrointestinal conditions. The primary outcome of this study was to evaluate the impact of anisodamine injection in ST36 on PONV in women following bariatric surgery.
Detailed description
At the onset of this investigation, we have already identified several methodologic issues, such as the timing of the acupuncture intervention, sample size, perioperative anesthetic techniques, and appropriate control groups. All subjects were randomly assigned to the following two groups: ST36 acupoint injection group (bilateral ST36 acupoint injection with scopolamine); pharmacoprophylaxis group (bilateral ST36 injection with normal saline). The primary outcome of this study was the total incidence of PONV during the hospital and after the discharge. Participants were randomly assigned into different groups according to the computer-generated randomization sequence (http://www.randomization.com). Patients, surgeons, care givers, anesthesiologists, nursing staff, and outcomes assessor, were all blinded to the group assignment.
Interventions
ST36 is located on the lateral surface of leg, 3 cun distal to the lower border of the patella, 1 finger-breadth lateral to the anterior crest of the tibia, between the tibialis anterior muscle and the tendon of the extensor digitorum longus. (The breadth of patient's middle finger was the proportional unit of measure the cun, defined as the distance between the two medial ends of the creases of the interphalangeal joints when the patient's middle finger is flexed).

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative food and water intake time | Postoperative 1-3 days | Duration of eating and drinking after surgery |
| Pittsburgh sleep quality index | Before surgery and at postoperative 3 months | Pittsburgh sleep quality index will be used to evaluate quality of sleep. The higher score means the lower quality of sleep. |
| Gastrointestinal Symptom Rating Scale | Before surgery and at postoperative 3 months | Gastrointestinal symptom rating scale (GSRS) will be used to assess gastrointestinal function. The score ranges from 0 to 45. The higher score means poorer gastrointestinal function . |
| Hamilton depression rating scale | Before surgery and at postoperative 3 months | Hamilton depression scale (HAMD) will be used to assess depression. HAMD 24 item version score range 0-96. The higher score means the higher possibility of depression. |
| Hamilton anxiety rating scale | Before surgery and at postoperative 3 months | Hamilton anxiety scale (HAM-A) will be used to assess anxiety. Total score ranges from 0 to 56, the higher the score is, the more serious the anxiety is. |
| The MOS item short from health survey ,SF-36 | Before surgery and at the postoperative 3 months.The scale consists of 36 items,divided into 8 sections,score of each section ranges from 0 to 100, the higher the score is, the healthier is. | Concise health status scale |
| 15-item Quality of Recovery(QoR-15) | Postoperative 24 hours | QoR-15 will be used to evaluate recovery quality after anesthesia, including 15 items covering sleep, satisfaction, emotion and pain et. al,total score ranges from 0 to 150,the higher score means the higher quality of recovery. |
| Postoperative pain | At 0-24 and 24-72 hours after surgery | Patients will be asked about their pain level at rest and moving on a numeric rating scale (0=no pain,10=worst pain imaginable) . |
| Consumption of analgesics | During 3 months after bariatric surgery | Cumulative analgesic consumption after surgery |
| Ambulation time | Postoperative 1-3 days | Interval time of patients' transit from bed rest to ambulation after surgery |
| Postoperative hospitalization duration | 2 weeks after surgery | Days of hospital staying after surgery |
