摘要目的：探讨直肠指力刺激法在防治胸腰椎骨折术后便秘患者中的应用效果。方法将不同节段的胸腰椎骨折术后80例患者随机分为实验组和对照组各40例。实验组早期采用直肠指力刺激直肠，配合常规肠道护理，对照组采用常规肠道护理。结果两组首次排便间隔时间、排便所需时间比较，差异均有统计学意义( P<0.01)，即实验组优于对照组。对照组便秘发生率占65%，实验组便秘发生率占30%，两组比较，差异有统计学意义( P<0.01)。结论对不同节段的胸腰椎骨折患者术后定时采用指力刺激法，能刺激腰骶部排便反射，促进排便，降低便秘的发生。

abstractsObjective To observe the efficacy of finger stimulation in rectum for prevention of postoperation constipation in patients with thoracic-lumbar fracture. Methods A total of 80 postoperative patients of thoracic-lumbar fracture were randomly divided into experimental group and control group with 40 cases each. Both groups received rou-tine intestinal nursing, and the patients of experimental group underwent finger stimulation in rectum at early stage. Results There were significant differences in interval time and cacation time by t test ( t=7. 003 and t=12. 60 , P<0. 01) . The constipation rates of experimental group and control group were 30% and 65% respectively, which was significant different compared by χ2 test (χ2=9. 825, P<0. 05) . Conclusions After surgery, finger stimulation in rectum for patients with thoracic-lumbar fracture can stimulate the defection reflex, promote cacation, and reduce the rate of constipation.
