The hourly urine volume and urine concentration of seven patients undergoing major abdominal surgery were measured during the operative and postoperative periods. From these, the hourly osmolar output was calculated. The results show that the osmolar output, 700 mOsm/day, in the peri-operative period is less than that of a 70 kg man consuming a normal 2000 calorie diet. Calculation of the osmolar output might help in the differentiation of postoperative oliguria and renal dysfunction.
在手术期和术后期间，对七名接受腹部大手术的患者的每小时尿量和尿浓度进行了测量。据此计算出每小时的渗透量。结果显示，围手术期每700毫渗透摩尔/天的渗透量低于一名体重70公斤、摄入正常2000卡路里饮食的男性的渗透量。计算渗透量可能有助于鉴别术后少尿和肾功能障碍。
