[70% glucose solution: clinical usefulness for postoperative management of anuric patients]

Hemodialysis is necessary for postoperative management of the patients with bilateral renal tumor or chronic renal failure, but taking into account the heavy burden imposed upon the patients, use of postoperative hemodialysis should be kept to the minimum. As one bottle (300 ml) of 70% glucose solution contains 840 cal, two bottles per day (its volume is nearly equal to intensive perspiration) is enough in calorific value. This 70% glucose solution was found useful for the management of patients with acute renal failure. Because the postoperative state of anuric patients is similar to the state of acute renal failure, this time we studied the clinical usefulness of a 70% glucose solution for the postoperative management of these patients. We administered 600 ml of a 70% glucose solution to three postoperative patients, who were operated on for bilateral renal tumor, bilateral renal pelvic tumor, and renal tumor with lung metastasis and who had been on chronic hemodialysis. The rate of blood urea nitrogen increase was very low, and hyperkalemia was not seen. We concluded that a 70% glucose solution was useful to delay the start of hemodialysis and to lessen its frequency, which suggests that it is useful to improve the postoperative course of anuric patients.
