The Impact of Epidural Analgesia on Perioperative Morbidity or Mortality after Open Abdominal Aortic Aneurysm Repair

BACKGROUND: Epidural analgesia (EA) is frequently used as an adjuvant to general anesthesia (GA) for improved postoperative analgesia and reduced rates of cardiac, pulmonary, and renal complications. However, only a few studies have examined EA-GA specifically during open abdominal aortic aneurysm (AAA) repair. The effects of EA-GA specifically during open AAA repair regarding postoperative outcomes are unknown. This study was performed to evaluate postoperative outcomes in patients undergoing open AAA repair with EA-GA versus GA alone.

METHODS: We performed a retrospective analysis for patients undergoing surgery between January 1, 2014 and December 31, 2016 using the National Surgical Quality Improvement Program (NSQIP) database. Propensity score matching was used to establish cohorts for analysis. Multivariable logistic regression was performed to determine significant perioperative outcomes for each anesthesia type. A total of 2,171 patients underwent open AAA repair in our date range; we excluded emergent and ruptured AAA. A total of 2,145 patients were included in our analysis, of whom 653 patients received EA-GA and 1,492 patients received GA only.

RESULTS: Major postoperative outcomes included mortality, pulmonary cardiac and renal complications, infections, thrombosis, and blood transfusion requirement (including Cell-Saver usage). Additional overall outcomes included hospital length of stay, return to the operating room, and readmission. Patients in EA + GA and GA alone groups were comparable regarding demographics, functional status, and comorbidities. Decreased odds of readmission was observed in EA + GA compared with GA (0.49, 95% CI [0.28-0.86]; P = 0.014); and increased odds of receiving a blood transfusion was observed in those who underwent EA + GA (1.63, 95% CI [1.23-2.14]; P = 0.001). No difference was observed between patients who had an AAA repair with EA + GA versus GA alone with regard to mortality, return to operating room, major pulmonary, cardiac, renal, or infectious complications.

CONCLUSIONS: EA + GA was not associated with decreased mortality or decreased rates of major postoperative pulmonary, cardiac, or renal complications. EA + GA was associated with increased transfusion requirements and decreased rates of hospital readmission.
