摘要

设计和开发了一套全自动(PC兼容)的软件和硬件分析系统，以快速、客观地分析结肠压记录。人工和计算机对8小时的结肠压迹进行了48个10分钟周期的分析，分析了平均振幅、活动%持续时间、运动指数、峰值数和活动指数等变量。方法之间的一致性良好:(偏差-0.5 mmHg;(36.8) (2 SD，约定限度);-5.8 ~ 4.8, 95%偏倚CI;0-289，两种方法值的平均范围)，活动持续时间%:(-0.9;(13.4);-2.9至0.9;0-100)，运动指数:(-55;(2072); -356 to 245; 0-26,220), number of peaks: (-20; (91); -44 to 3.5; 1-211), and activity index bias -5.2 mmHg. min; (127.3); -23.7, to 13.2; 0-2159. The time taken for manual analysis was 889 minutes compared with 14 minutes for the automated system. Fully automated analysis of colonic pressure records is fast, objective, and shows good agreement with labour intensive manual analysis. Previously acquired data can be reanalysed using new definitions and criteria. Widespread use of the technique could introduce uniformity in colonic pressure record analysis. In addition this wave form analysis system can be adapted to record and analyse pressure data from other regions of the gastrointestinal tract.
