Urinary output has been used as a measure of adequate renal perfusion during anesthesia and surgery. In this study, 40 consecutive patients undergoing elective aortic reconstruction were studied to determine whether intraoperative urinary output was predictive of postoperative renal function as measured by blood urea nitrogen (BUN) and creatinine concentrations on postoperative days 1, 3 and 6, or 7. Pulmonary capillary wedge pressures or central venous pressures were kept at or above preoperative values. All patients received 22.5 g of mannitol IV prior to aortic crossclamping. No significant correlation was noted between either mean intraoperative urine output or lowest hourly urine output and postoperative BUN and creatinine concentrations. Complete interruption of renal blood flow in nine of the 40 patients had no significant effect on the correlations. Consequently, intraoperative urine output does not appear predictive of postoperative renal insufficiency in patients undergoing elective aortic reconstruction. |
