目的:评价番泻叶联合甘露醇进行肠道清洁对多层螺旋CT肠道成像的影响.方法:回顾性收集2011年6月-2012年6月在我院行多层螺旋CT肠道成像检查的炎性肠道疾病患者52例,根据肠道准备方法将患者分为对照组(22例)和观察组(30例).两组患者在检查前12 h禁食,对照组患者在检查前12 h给予中药材潘泻叶20 g加500 ml开水浸泡半小时服用,然后再次加入500 ml开水浸泡半小时服用,同时饮清水1 000 ml;观察组患者在检查前1 d早餐后2 h采用中药材番泻叶10 g加500 ml开水浸泡服用,中餐后2 h再次加入500 ml开水浸泡服用,晚餐后2 h口服10%甘露醇500 ml,同时饮清水1 000 ml.两组患者服药后直至大小便排出清水样无粪时采用多层螺旋CT肠道成像检查.比较两组患者肠道清洁有效率、成像质量、不良反应发生率.结果:观察组患者肠道清洁有效率为100%,显著高于对照组的81.82%,差异有统计学意义(P<0.05);观察组患者成像质量优良率为96.67%,显著优于对照组的81.82%,差异有统计学意义(P<0.05);观察组患者腹痛腹胀、恶心呕吐、肠黏膜损伤等不良反应的发生率均显著低于对照组,差异有统计学意义(P<0.05).结论:番泻叶联合甘露醇是多层螺旋CT肠道成像检查中有效的肠道准备方法,肠道清洁效果好、成像质量高,且不良反应发生率较低.“,”OBJECTIVE:To evaluate the effects of Sennae Folium combined with mannitol for bowel cleaning on multi-slice spiral CT bowel imaging. METHODS:52 patients receiving multi-slice spiral CT imaging examination in our hospital during Jun. 2011 to Jun. 2012 were collected retrospectively,and then divided into control group(22 cases)and observation group(30 cases) according to the methods of bowel preparation. Both groups fasted for 12 h before examination. Sennae Folium 20 g soaked in boiled water 500 ml for half an hour was given to patients in control group 12 h before examination,and then was soaked in boiled water 500 ml again for drinking and other pure water 1 000 ml was also given to patients. Sennae Folium 10 g soaked in boiled wa-ter 500 ml was given to patients in observation group 1 d before examination and 2 h after breakfast;soaked in boiled water 500 ml again 2 h after lunch;10% mannitol 500 ml and pure water 1 000 ml were given to patients after supper. Both groups received multi-slice spiral CT bowel imaging until the patients defecated watery stool after medication. The effective rate of bowl cleaning, image quality and the incidence of ADR were compared between 2 groups. RESULTS:The effective rate of bowel cleaning was 100% in observation group,which was significantly higher than that of control group(81.82%),with statistical significance(P<0.05). The excellent and good rate of imaging quality was 96.67% in observation group,which was significantly better than that of control group(81.82%),with statistical significance(P<0.05). The incidence of ADR as abdominal distension,nausea,intestinal mucosa damage in observation group were significantly lower than those of control group,with statistical significance (P<0.05). CONCLUSIONS:Sennae Folium combined with mannitol is effective method to prepare enteric multi-slice spiral CT imaging exam-ination,and perform good bowl cleaning effect,high image quality and low incidence of ADR.
