Evaluation of Renal Function at 24, 48, and 72 Hours and 3 Months After Transplant: Comparison of 3 Anesthetic Techniques.

Background: General anesthesia is the conventional management of renal transplant, and its evolution has revolved around the development of new drugs; however, a group of patients meet conditions for neuraxial anesthesia, because of their comorbidities, who are at greater risk of complications with general anesthesia and are not favorable to grafting.

Methods: We conducted a controlled clinical trial of 109 renal transplant recipients where renal function was evaluated at 24, 48, and 72 hours and 3 months after transplant, and we compared regional, general anesthesia with inhaled anesthetic and total intravenous anesthesia. It was performed for 1 year, and serum creatinine, urea nitrogen, and electrolytes were evaluated. During the intraoperative period central venous pressure, mean arterial pressure, vasopressors, fluid therapy, diuretics, surgical time, anesthesia, hot and cold ischemia, immunosuppressants, and antihypertensives were evaluated. They were analyzed with χ independence and 1-way and 2-way repeated measures.

Results: The type of anesthesia was associated with hemodynamic stability (P = .018), the use of vasopressor (P = .005), and fluid therapy (P = .011). A value of P = .005 was found for central venous pressure at discharge from the operating room, and preincisional mean arterial pressure (P = .015) was among the types of anesthesia. Creatinine, blood urea nitrogen, sodium, and potassium were statistically significant over time (P < .001) but showed no difference between types of anesthesia.

Conclusion: There is no difference between anesthetic techniques and clinical results over time. The personalized anesthetic technique will improve the neuroendocrine response and surgical stress, decrease the need for vasopressors and analgesics, and reduce complications.
