There have been remarkable advances in anesthetic care in the last several decades. However, the recommendation to use urine output (0.5 mL/kg of body weight) to guide intraoperative fluid administration is rarely challenged. This study by Matot et al1 is an important contribution to the literature. Matot and colleagues convincingly suggest that patients undergoing laparoscopic gastric bypass are oliguric regardless of the amount of fluid administered. Furthermore, their data suggest that the cohort receiving less fluid may have better outcomes.
