A Comparison of Kidney Function After Nephrectomy in Living Donors Under Sevoflurane and Desflurane Anesthesia
Living-donor kidney transplantation has been considered as the best treatment for patients with end-stage renal disease (ESRD). Kidney donation from living donors has been performed widely under their noble humanity and a belief that donation would not harm the donor. Although the overall evidences proposed that living kidney donor have medical outcomes similar to those in general population, several reports have demonstrated the potential risks for development of hypertension, proteinuria, and ESRD. Thus, all efforts should be concentrated on ensuring their safety and preserving the function of their remained kidney during anesthesia maintenance.
Inhaled anesthetics have been frequently used for the induction and maintenance of general anesthesia. The metabolism of certain inhaled anesthetics can produce inorganic fluoride, which may be directly nephrotoxic through impairments of renal concentrating ability. The typical inhaled anesthetics commonly used nowadays are sevoflurane and desflurane. The defluorination of sevoflurane can results in increased serum inorganic fluoride ion concentrations, but any neprhotoxic effect of sevoflurane has not been proven yet in human. On the other hand, desflurane is extremely resistant to defluorination, and desflurane does not appear to be nephrotoxic.
The inhaled anesthetics which are currently used in general anesthesia have no clinical evidence of nephrotoxicity, but the possible risks cannot be excluded entirely, especially in the patients who one kidney is donated. The purpose of the current retrospective, single center study was to evaluate and compare postoperative renal function of living kidney donor after nephrectomy under sevoflurane or desflurane anesthesia, and make evidence-based recommendations of proper inhaled anesthetics for anesthesia of living kidney donor.
|Study Design:||Observational Model: Cohort
Time Perspective: Retrospective
- Postoperative renal function of living kidney donor after nephrectomy under sevoflurane or desflurane anesthesia [ Time Frame: Participants will be followed for postoperative period, approximate 1 week through chart review. ] [ Designated as safety issue: No ]We collect laboratory data of the patients which were underwent at preoperative period and during postoperative periods. The laboratory data includes hemoglobin (Hb), hematocrit (Hct), platelet, prothrombin time (PT), albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), creatinine (Cr) and estimated glomerular filtration rate (eGFR) which was calculated by the Modification of Diet in Renal Disease (MDRD) formula with age, gender, race, and serum creatinine as variables.
