ABSTRACT
A randomized trial was undertaken to reassess the effectiveness of mannitol in preventing postoperative renal impairment in patients with obstructive jaundice. The study included 31 patients with obstructive jaundice (bilirubin, 3 mg/dl or higher) randomly allocated in two groups to receive (n = 17) or not receive (n = 14) preoperative mannitol. Sixty-five percent of patients had a creatinine clearance below 70 ml/min before surgery. Serum bilirubin and bacteribilia had no relation with preoperative renal function. No relation was found between serum bilirubin value and the percentage fall in postoperative creatinine clearance. Compared with the preoperative values, the postoperative creatinine clearance was significantly impaired in the mannitol group (p = 0.03) and remained almost unaltered in the no-mannitol group. Three patients (9.7%) died of acute renal failure; two were in the mannitol group and one was in the no-mannitol group. Serum fibrin degradation products were not sensitive markers for impending renal failure. There was no significant difference in postoperative serum sodium concentration or in the urinary sodium excretion. Administration of mannitol did not improve the postoperative renal function of jaundiced patients, nor did it prove beneficial in preventing renal failure. Our results suggest that severe disturbances of body-fluid compartments may be the basic mechanism underlying kidney dysfunction in obstructive jaundice and that further water depletion induced by mannitol may indeed prove detrimental.
