Perioperative anesthetic management for laparoscopic kidney donation.

OBJECTIVES: To report a single-center experience about the perioperative and anesthetic management of laparoscopic living kidney donation. PATIENTS AND INTERVENTIONS: Subjects undergoing laparoscopic (n = 39) (performed between April 2000 and August 2002) and traditional "open" kidney donation (n = 27) received a standard balanced anesthetic technique. However to counterbalance the reported abdominal insufflation-related kidney dysfunction, laparoscopic donors were administered an extra intravascular volume loading with colloid and crystalloid starting on the night before surgery. RESULTS: Laparoscopic donors underwent longer procedures with lower estimated blood losses (P =.0001), were intraoperatively administered higher amounts of intravenous fluids (P <.01), showed less postoperative analgesic requirement (P <.0001), shorter intensive care unit and overall hospitalization (P <.001), quicker resumption of solid oral intake (P <.01), and full return to work (P <.001) with no difference in the postoperative complication rate. Diuresis resumed intraoperatively in all recipients and early graft function did not differ between the two groups, although the serum creatinine declined earlier, but not significantly, in those receiving kidneys procured by the traditional method. No difference was seen in graft rejection rates. DISCUSSION AND CONCLUSIONS: Laparoscopic kidney donation does not require a particularly complex or expensive anesthetic management or approach; as it has been suggested that intra-abdominal hypertension coming from CO(2) insufflation inside the donor's peritoneal cavity may threaten graft function, during laparoscopic kidney donation it is advisable to adopt a strategy for "renal protection." Thus, when a laparoscopic kidney donation is performed at our center, a multidisciplinary approach is commonly adopted based on three key points: perioperative positive volemic balance in donors; intraoperative urinary output of at least 100 mL/h; inflation with an abdominal pressure not exceeding 12 mm Hg.

Perioperative management for laparoscopic kidney donation.

AIM: To report a single centre's experience in the perioperative management of live kidney laparoscopic donations. METHODS. DESIGN: comparative analysis of all laparoscopic kidney donations performed between April 2000 and August 2002 and a corresponding number of "traditional surgery" donors from a historical series. SETTING: kidney transplant centre of a teaching hospital. INTERVENTIONS: 39 and 27 subjects undergoing respectively laparoscopic and traditional "open" kidney donation were studied. A standard balanced anesthesiological technique was used in both groups but, to counterbalance the reported abdominal insufflation-related kidney dysfunction, laparoscopic donors were administered an extra intravascular volume loading with colloids and crystalloids starting from the night before surgery. RESULTS: Laparoscopic donors underwent a longer procedure with a lower estimated blood loss (p=0.0001) and were intraoperatively administered with a higher amount of intravenous fluids (p<0.01); they showed less postoperative analgesic requirement (p<0.0001), a shorter ICU stay and overall hospitalisation (p<0.001), a quicker resumption of solid oral intakes (p<0.01) and full return to work (p<0.001) with no difference in the rate of postoperative complications. Diuresis resumed intraoperatively in all recipients and early graft function did not differ in the 2 groups although serum creatinine declined earlier, but not significantly, in those receiving kidneys by the traditional method. CONCLUSION: Kidney laparoscopic donation does not require a particularly complex or expensive anaesthetic management or approach; it is advisable to adopt strategies to counterbalance laparoscopy-associated abdominal hypertension.
