Epidural anesthesia may be associated with increased postoperative complications in the elderly population undergoing radical cystectomy: an analysis from the National Surgical Quality Improvement Project (NSQIP) database.

BACKGROUND: Epidural anesthesia has been associated with a decrease in cardiopulmonary complications and a decrease in blood loss in orthopedic procedures. Its influence on the outcomes of patients receiving radical cystectomies is unknown. We aim to use the large national database from the National Surgical Quality Improvement Project (NSQIP) to examine whether postoperative complications may be affected by the use of epidural anesthesia during radical cystectomy. METHODS: Data were collected from the 2014-2016 participant user files of the NSQIP database. Patients receiving radical cystectomy were identified by CPT code and further stratified by anesthesia type. Demographics, length of stay, and 30-day complications including death were collected and analyzed using univariable and multivariable analysis. RESULTS: A total of 6448 patients met the inclusion criteria for analysis. Between 2014 and 2016, 5064 patients received general anesthesia only (GA) and 1384 patients received general and epidural anesthesia (GEA). Statistical analysis showed an overall increase in major complications (17.8% vs 18.5%) in the GEA group (p = 0.0046). Subgroup analysis showed major complications to be more likely in patients older than 75 years receiving GEA instead of GA (p = 0.0301). CONCLUSIONS: Elderly patients (age > 75) undergoing radical cystectomy may experience more major complications with the use of epidural anesthesia. This may be due to end-organ effects from the hemodynamic changes of epidural anesthesia which are poorly tolerated in the elderly population. Further single intervention epidural studies need to be performed to isolate the effects of epidural anesthesia on individual surgical procedures.
