Objective To study the effects of modulated medium frequency electrotherapy and nursing interventions on postoperative adhesive intestinal obstruction. Methods A total of 42 adhesive intestinal obstruction patients treated from January 2017 to October 2019 in our hospital were selected and randomly assigned to two groups, with 21 cases in each group. The control group took routine therapy and nursing care; the observation group took medium frequency electrotherapy and comprehensive nursing interventions. Nursing effects between the two groups were probed. Results The exhaust time, initial bowel sound time, and gastrointestinal recovery time in the observation group were significantly shorter than those in the control group (P<0.05); the watery stool time and gastric fluid clearance time in the observation group were also shorter than those in the control group (P<0.05); the total effective rate in the observation group (95.24%) was significantly higher than the rate in the control group (76.19%， P<0.05). Conclusion Applying modulated medium frequency electrotherapy and nursing interventions to patients with postoperative adhesive intestinal obstruction can improve gastrointestinal function and treatment prognosis, showing significant clinical effects.
