ST36 Acupoint Injection With Anisodamine for Postoperative Nausea and Vomiting

July 13, 2022 updated by: hui hou, The Second Hospital of Anhui Medical University

Zusanli (ST36) Acupoint Injection With Anisodamine for Postoperative Nausea and Vomiting in Women Following Bariatric Surgery: A Single-center Study

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.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Placebo Comparator: Conventional treatment group
Patients in the placebo group will receive bilateral ST36 injection with normal saline 1ml/point
Procedure: ST36 acupuncture
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).
Experimental: ST36 acupoint injection group
Patients in the experimental group will receive bilateral ST36 injection with anisodamine 1ml/point
Procedure: ST36 acupuncture
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).
