title: Perioperative fluid management in kidney transplantation: is volume overload still mandatory for graft function?
abstract: Kidney transplantation is now recognized as the treatment of choice for patients with chronic renal failure. Despite the extension of indications to patients suffering severe hypertension, ischemic heart disease, and chronic heart failure, the worldwide results are superb. However, perioperative cardiac complications occur in 6% to 10% of transplanted patients. Aggressive intraoperative volume expansion is still recommended to maximize graft functional recovery (up to 30 mL/kg/h, central venous pressure [CVP] > 15 mm Hg), but patients with preexistent cardiac disease or poor myocardial function are exposed to the risk of fluid overload, acute respiratory failure, and prolonged ventilation. Among the last 90 cases performed at our institution, good functional recovery of the graft was present in 94% of the patients within 2 weeks, despite a much more conservative intraoperative hydration policy (crystalloids 2400 +/- 1000 mL, 15 mL/kg/h, CVP 7-9 mm Hg). Graft failure which occurred in 5 patients was significantly correlated only with donor age, while perioperative cardiovascular complications had been present in 9 cases (10%) who were coronary artery disease patients (55%). Age above 50 years was the only significant risk factor. Supranormal volume loading is probably not always warranted in kidney transplantation.
