Total body water and total body potassium were studied in 14 patients submitted to proctocolectomy six to 10 years after they had been provided with a continent ileostomy. Total body water was determined with an isotope dilution technique using tritiated water as a tracer. Total body potassium was determined by counting the gamma radiation from the naturally present nuclid 40K in a total body counter. The results were compared with 'normal values' produced by multiple regression analysis of data from 476 healthy controls which had been published earlier from the same laboratory. The investigations showed no signs of water or potassium depletion in patients with continent ileostomies.
对14例在接受可控性回肠造口术后6至10年接受直肠结肠切除术的患者进行了总体水和总体钾的研究。采用以氚水为示踪剂的同位素稀释技术测定总体水。通过全身计数器对天然存在的核素40K的γ辐射进行计数来测定总体钾。将结果与同一实验室先前发表的476名健康对照者数据的多元回归分析得出的“正常值”进行比较。研究表明，可控性回肠造口术患者没有水或钾缺乏的迹象。
