This study was performed to compare the patient acceptability and the efficacy of two different agents for bowel preparation prior to double contrast barium enema. One-hundred and ninety-four outpatients were randomized to have either two sachets of Picolax or two bottles of Fleet Phospho-soda and restricted to clear fluids on the day prior to their examination. Patients answered a short questionnaire before their enema. The decubitus films were assessed for faecal residue and bowel coating by three observers blinded to the type of preparation used. There was no significant difference in faecal residue nor in the bowel coating between the preparations. However patients found Picolax significantly easier to take, being better tasting and provoking less nausea and vomiting than Fleet Phospho-soda.
本研究旨在比较两种不同药物用于双重对比钡灌肠前肠道准备时患者的可接受性及疗效。194名门诊患者被随机分为两组，分别服用两包聚乙二醇电解质散或两瓶磷酸钠盐灌肠液，并在检查前一天限制饮用清流。患者在灌肠前回答一份简短问卷。由三名对所用准备药物类型不知情的观察者对卧位片的粪便残留和肠壁涂布情况进行评估。两种药物在粪便残留和肠壁涂布方面无显著差异。然而，患者发现聚乙二醇电解质散服用起来明显更容易，味道更好，引起的恶心和呕吐也比磷酸钠盐灌肠液少。
