Acupuncture has been used as a medical technique in China for at least 2,000 years. More recently, it's also been extensively used in managing headache, chronic back pain, and PONV in USA. ST36 acupuncture is reported to be an effective preventive treatment for postoperative nausea and vomiting (PONV). However, It is not clear if it could efficiently prevent PONV in female patient who has underwent bariatric surgery. 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. 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 with a computer-generated randomization sequence (http://www.randomization.com). Patients, surgeons, anesthesiologists, nursing staff, and the research assistant, were all blinded to the group assignment.
Postoperative nausea and vomiting (PONV) is particularly distressing although it is not a fatal postoperative complication. 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 laparoscopic sleeve gastrectomy. 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.
