目的 :为了满足直肠癌根治手术位式要求 ,最大限度地保证患者舒适和安全。方法 :将施行直肠癌根治术患者 172例 ,随机分为两组 ,A组 (手测法 )采用拇指、中指法测试固定脚架高度 ,示指、拇指法测试固定脚架外展角度 ;B组采用 (目测法 )传统方法。观察两组摆位时间 ;双侧脚架摆放高度、角度是否均衡 ;术后随访患者舒适情况。结果 :两组摆位时间经 STATA软件统计分析 ,t=- 2 1.0 1,P<0 .0 1;双侧脚架高度、角度固定后测试结果 ,χ2值分别为 18.0 5、2 4.5 2 ,均 P<0 .0 1;术后随访 ,A组 87例患者舒适率达 99.85 % ,B组 85例舒适率为 90 .5 9% ,经四格表精确概率法检验 ,P<0 .0 5。提示手测法优于目测法 ,摆位后双侧脚架固定均衡 ,而且省时、省力 Objective: In order to meet the requirements of radical operation of rectal cancer, to ensure maximum patient comfort and safety. Methods: A total of 172 patients undergoing radical resection of rectal cancer were randomly divided into two groups. Group A (hand test) used the thumb and middle finger method to test the height of the fixed stand, Using (visual method) the traditional method. Observed two sets of positioning time; bipod placement height, angle is balanced; patients were followed up for comfort. Results: The two groups of position time by STATA software statistical analysis, t = - 2 1.01, P <0. 01; bipod height, angle after the test results, χ2 values ​​were 18.0 5,2 4.5 2, All patients were followed up. The comfortable rate of 87 patients in group A was 99.85%, and the comfortable rate of 85 patients in group B was 90.59%. The accuracy was tested by four tables, P <0. 0 5. Tip hand measurement is better than the visual method, after setting a fixed balance of bilateral tripod, and save time and effort
