Effects of Transcutaneous Acupoint Electrical Stimulation on Intestinal Obstruction After Gastrointestinal Surgery

Study Overview
=================
Brief Summary
-----------------
Postoperative intestinal obstruction (POI) is one of the most common complications in the gastrointestinal surgery. Compared with the conventional control group, transcutaneous acupoint electrical stimulation(TEAS) is possible to reduce the incidence of POI and accelerate the rapid recovery of the gastrointestinal tract.

Detailed Description
-----------------
Participants will be randomly assigned, in a 1:1 ratio, to receive TEAS or Blank treatment (acupoints selection are same with the experimental group, connect stimulator for patients, but not don't give stimulus). The randomization sequence will be computer-generated, and randomization will be performed in blocks and will be stratified according to participating center. TEAS will be performed in a series of time periods after operation. Time of first fart and food-taking ,time of have normal diet after the transplantation will be recorded. The participation of each patient is scheduled for 30 days.

Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: TEAS group<br>Choose several acupoints,give 2/10 hz dilatational wave stimulation.Complete the 30 minutes intervention after extubation and 1-3 days after surgery.Give a health education on the first postoperative day. | Device: transcutaneous acupoint electrical stimulation<br>* Transcutaneous acupoint electrical stimulation is same to the traditional Chinese medicine acupuncture treatment,treat diseases by stimulate different acupuncture points.<br>|
| Experimental: no TEAS group<br>The choice of acupoints are same with TEAS group,tape over the electrode but don't give electroacupuncture stimulation,the others steps are same with TEAS group. | Device: no transcutaneous acupoint electrical stimulation<br>* the choice of acupoints are same with TEAS group,tape over the electrode but don't give electroacupuncture stimulation.<br>|
