【Abstract】 Objective To study the effect and the prognosis of mother and infant of the insertion type intestinal obstruction catheter in treatment of pregnancy simple intestinal obstruction. Methods 36 patients of pregnancy simple intestinal obstruction received therapy from February 2018 to August 2019 in our hospital were selected as research objects. They were divided into the observation group and the control group by the random number table, each group had 18 cases. On the basis of routine treatment, the control group was given routine indwelling nasogastric tube for gastrointestinal decompression, and the observation group was given inserting intestinal obstruction tube for gastrointestinal decompression. The 24hour clinical efficacy, clinical indicators and maternal and infant outcomes in the two groups were compared. Results The 24hour clinical efficacy of the two groups was 88.89% and 72.22%, respectively. The difference was not statistically significant(P＞0.05). The 24hour drainage volume in the observation group was significantly higher than those in the control group. The abdominal pain disappearance time, anal exhaust time, defecation time and hospitalization time were significantly shorter than those in the control group［（578.55±187.30）mL vs（330.71±102.61）mL，（2.64±0.73）d vs（4.04±0.85）d，（1.84±0.49）d vs（2.46±0.61）d，（2.35±0.44）d vs（3.04±0.58）d，（5.31±0.86）d vs（6.60±1.15）d］（P＜0.05）. There was 14 patients (77.78%) were discharged after treatment in the observation group. There was 10 patients (55.56%) were discharged after treatment in the control group. The difference was not statistically significant(P＞0.05). Conclusion Compared with the traditional indwelling nasogastric tube, the insertion type intestinal obstruction catheter can effectively shorten the symptom relief time and hospitalization time in patients with simple ileus during pregnancy, and improve the drainage volume. It is still necessary to consider the individual situation of patients and choose the most effective treatment to ensure the safety of mothers and infants.
