女性盆腔CT扫描前肠道准备提速的方法探讨

A methodological study on elevating the velocity of intestinal tract preparat ion before CT scan of pelvic cavity

目的通过对女性盆腔CT扫描前肠道准备方法的改良,与传统的盆腔CT扫描前的肠道准备方法进行比较,评价改良法对盆腔肠道准备时间缩短的意义。方法选择22岁～55岁之间B超诊断为卵巢或子宫占位性病变、没有任何心血管疾病和肺、肝、肾功能不全的54例病人,随机分为实验组采用改良方法准备肠道,对照组采用传统的方法准备肠道,观察盆腔肠道充盈完好所需的时间,进行统计学处理。结果实验组盆腔肠道充盈完好的平均时间为164min,对照组平均时间为513min,经统计学处理,两组病人在盆腔肠道充盈时间上有显著性差异,P<0.01。结论本研究表明,盆腔肠道采用改良方法准备平均可缩短时间349min,这不仅减轻了患者的身心压力,给患者带来了极大方便,而且简化了医护人员的工作程序。这种盆腔肠道改良提速方法效果好,安全、迅速,在临床CT诊断上有重要价值。

Objective Through comparing the consumed time of traditional method and modified method during complete fill of pelvic cavity and intestinal tract before CT scan, to assess the significance of modified method in shortening CT examination time. Methods Fifty-four femal patients （aged 25 ～ 55 years ）with ovarian or uterine space-occupying lesions those were diagnosed by ultrasound but without pulmonary, hepatic and renal disfunction were selected and randomly divided into the following two groups： experimental group（n = 27） underwent modified method and control group（ n = 27） underwent traditional method . The consumed time of the both methods for completely filling pelvic cavity and intestinal tract was observed and analyzed statistically. Results The consumed time for completely filling pelvic cavity and intestinal tract in experimental group ranged fron 150 minutes to 180 minutes, mean, 164 minutes, while that in control group ranged from 480 minutes to 540 minutes , mean, 513 minutes. There was statistic difference in the both groups （ P 〈 0.01 ）. Conclusion Compared with traditional method, modified method shortened the consumed time for completely filling pelvic cavity and intestinal tract by 349 minutes so that it can not only relieve the physical and psychic pressure of the patients but can simplify the working process of the doctors and nurses. This modified method is effective, safe, and quick in the diagnosis of femal pelvic cavity diseases and therefore it is worth clinically wide application.
