Efficacy and safety of the “Xingnao Kaiqiao” acupuncture technique via intradermal needling to treat postoperative gastrointestinal dysfunction of laparoscopic surgery: study protocol for a randomized controlled trial

摘要

Xingnao Kaiqiao acupuncture involves needling of the Neiguan (PC6), Renzhong (DU26), and Sanyinjiao (SP6) acupoints. The technique has a significant clinical effect in many neurological diseases. In the present report, we have developed a protocol for a scientific trial to analyze whether Xingnao Kaiqiao can be used to treat gastrointestinal dysfunction after laparoscopic surgery. In this context, we intend to execute a double-blind, randomized controlled trial to assess the efficacy and safety of Xingnao Kaiqiao acupuncture via intradermal needling. This will be a single-center, double-blind, randomized controlled clinical trial. It has been designed on the basis of the Consolidated Standards of Reporting Trials (CONSORT 2010) guidelines and the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). The subjects will be recruited from among inpatients scheduled for laparoscopic surgery at the Department of Minimally Invasive Surgery, Tianjin Nankai Hospital, Tianjin, China. Using random numbers generated in SPSS 19.0, the recruited subjects will be allocated to either the “Xingnao Kaiqiao” group or the sham stimulation group. A specially appointed investigator will be in charge of the randomization. Xingnao Kaiqiao via intradermal needling (or sham needling) will be administered 6?h after laparoscopic surgery, and then every 12?h for a total of six sessions, each of which will last 3?min. The subjects will undergo their first evaluation shortly before the first treatment (6?h after laparoscopic surgery); evaluations will be repeated every 12?h until a total of seven evaluations have been completed. The primary outcome will be the time until the first postoperative flatus. The secondary outcomes will be: the time until the first postoperative defecation; levels of abdominal pain, abdominal distension, and nausea; blood ghrelin level; occurrence of vomiting; psychological status; and quality of life. This upcoming randomized clinical trial was designed as a standardized method to assess the efficacy and safety of Xingnao Kaiqiao acupuncture using intradermal needles on PC6, DU26, and SP6 in the treatment of gastrointestinal dysfunction after laparoscopic surgery. We aim to provide evidence and thus improve the clinical application of this technique. Chinese Clinical Trial Registry, ChiCTR-IOR-17010763 . Registered on 2 March 2017.
