Objectives To observe the clinical curative effect of Wuzhuyu acupoint on the treatment of gastrointestinal dysfunction in severe patients. Methods A total of 60 patients with gastrointestinal dysfunction were randomly divided into treatment group and control group, 30 patients in each group. The control group was treated with routine western medicine, and the treatment group was given the acupoint application of Wuzhuyu on the basis of routine treatment. The treatment last 7 days. The clinical efficacy was evaluated by observing bowel sounds recovery time, exhaust time and defecating time, enteral nutrition tolerability, gastrointestinal dysfunction score and acute physiology and chronic health evaluation (APACHE Ⅱ). Results The treatment group showd significantly shorter bowel sound recovery time and anal exhaust time than the control group (t value were 8.811, 5.538, 8.908, all P value <0.01). The enteral tolerance rate was 80.0％ (24/30), and the control group tolerance rate was 53.3％ (16/30). The tolerance rate of treatment group was significantly higher than that of control group (χ2=4.720, P=0.030). The Gastrointestinal dysfunction score and APACHE Ⅱ score in treatment group were significantly lower than control group (t value were 3.873,2.805,all P value <0.01). Conclusions The acupoint application of Wuzhuyu can promote the recovery of gastrointestinal function, increase the tolerance of enteral nutrition, and reduce the severity of the patient's condition and improve the prognosis of patients.
