Efficacy of Continuous Epidural Analgesia versus Total Intravenous Analgesia on Postoperative Pain Control in Endovascular Abdominal Aortic Aneurysm Repair : A Retrospective Case-Control Study

Abstract EN

We reviewed our experience to compare the effectiveness of epidural analgesia and total intravenous analgesia on postoperative pain control in patients undergoing endovascular abdominal aortic aneurysm repair.

Records of 32 patients during a 2-year period were retrospectively investigated.

TIVA group (n=18) received total intravenous anesthesia, and EA group (n=14) received epidural anesthesia and sedation.

Pain assessment was performed on all patients on a daily basis during rest and activity on postoperative days until discharge from ward using the numeric rating scale.

Data for demographic variables, required anesthetic level, perioperative hemodynamic variables, postoperative pain, and morbidities were recorded.

There were no relevant differences concerning hospital stay (TIVA group: 14.1 ± 7.0, EA group: 13.5 ± 7.1), perioperative blood pressure variability (TIVA group: 15.6 ± 18.1, EA group: 14.8 ± 11.5), and perioperative hemodynamic complication rate (TIVA group: 17%, EA group: 14%).

Postoperative pain scores differed significantly (TIVA group: 5.4 ± 0.9, EA group: 1.8 ± 0.8, P<0.001).

Epidural anesthesia and postoperative epidural analgesia better reduce postoperative pain better compared with general anesthesia and systemic analgesia, with similar effects on hemodynamic status.
