开腹手术后麻痹性肠梗阻发生危险因素分析

目的对开腹手术后麻痹性肠梗阻发生的危险因素进行分析。方法回顾性分析2011年1月至2014年12月730例接受开腹手术治疗患者临床资料,采用回归分析方程确定麻痹性肠梗阻发生的危险因素。结果开腹手术患者并发麻痹性肠梗阻发生率为5.6%。单因素分析显示年龄≥60岁、手术时间≥3 h、低蛋白血症、肠粘连范围广、疾病恶性程度和术后白细胞计数≥10×109/L患者麻痹性肠梗阻发生率高,差异具有统计学意义(χ2=5.452、5.295、10.365、9.527、4.905、10.442,P0.05)。多元回归分析显示腹部手术史、手术时间长、肠粘连范围广和无肠道准备是开腹手术后麻痹性肠梗阻发生的危险因素(P0.05)。结论腹部手术史、手术时间长、肠粘连范围广和无肠道准备是开腹手术后麻痹性肠梗阻是麻痹性肠梗阻发生的危险因素,临床工作中应当对上述患者予以干预。

Risk factors of paralytic ileus after open abdominal surgery

Objective To analyze the risk factors of paralytic ileus after open abdominal surgery . Methods We retrospectively analyzed the clinical data of 730 patients who underwent open abdominal surgery from January 2011 to December 2014.Regression analysis was made to determine the risk factors of postoperative paralytic ileus . Results The incidence of paralytic ileus was 5.6% after open abdominal surgery.Univariate analysis showed that paralytic ileus was associated with age ≥60 yr, operation time≥3 h, hypoalbuminemia , extensive adhesion of intestine , malignant disease and postoperative leukocyte count ≥10 ×109/L (χ2 =5.452, 5.295, 10.365, 9.527, 4.905, 10.442 respectively, P <0.05). Multiple regression analysis showed that risk factors of paralytic ileus after open abdominal surgery included history of abdominal surgery , long operation time, extensive adhesion and no bowel preparation (P<0.05). Conclusion History of abdominal surgery , long operation time , extensive adhesion and no bowel preparation are risk factors for paralytic ileus after open abdominal surgery .
