Orthopaedic patients hospitalized for surgery or confined to bed are at high risk for constipation. To determine if wheat bran ingestion would result in more stools, less laxative use, and a lower incidence of constipation after orthopaedic surgery, 16 orthopaedic patients were randomly assigned to experimental and control groups for 7 days. The study concluded that those experimental subjects who ate more wheat bran did have more bowel movements and requested fewer laxatives.
因手术住院或卧床的骨科患者便秘风险很高。为了确定摄入麦麸是否会使骨科手术后的患者排便增多、减少泻药使用并降低便秘发生率，16名骨科患者被随机分为实验组和对照组，为期7天。研究得出结论，摄入较多麦麸的实验组受试者排便次数确实更多，且使用泻药的次数更少。
