Abstract: Objective To explore clinical effect of pernasal intubation intervention in adhesive intestinal obstruction.Methods A total of 200 patients with adhesion intestinal obstruction were selected from our hospital, and the patients were divided into two groups: control group and experimental group, 100 patients in a group. The patients of control group underwent conventional treatment (nasogastric tube gastrointestinal decompression), those of experimental group got intervention combined with conventional treatment. Comparison was made in the drainage flow in three days after treatment, exhaust time, remission time of abdominal distension and pain, the clinical therapeutic effect and complications (perforation, bleeding, narrow, transit operation) between two groups.Results The drainage flow and exhaust time, abdominal distension, abdominal pain relief time in treatment group were better than those in control group (P<0.05).The clinical cure rate of experimental group was significantly higher than that of control group (89% vs 58%,P<0.05).The incidence of complications in experimental group were less than those of control group (9% vs 21%,P<0.05).Conclusion Pernasal intubation intervention for adhesive intestinal obstruction showed obvious clinical effect, quick remission of symptoms, higher cure rate,but fewer complications, so the method may be used widely in clinic.
