The effects of spinal anesthesia vs epidural anesthesia on 3 potential postoperative complications: pain,urinary retention,and mobility following inguinal herniorrhaphy

This study was conducted to determine the effects of spinal (n = 113) vs epidural (n = 31) anesthetic techniques on 3 common postoperative complications: pain, urinary retention, and mobility for patients undergoing inguinal herniorrhaphy. The study design was a retrospective chart review. Data were collected on 144 subjects who underwent herniorrhaphy between January 1 and December 31, 1999, had an ASA classification of I to III, and were older than 18 years. The local anesthetics used to provide spinal anesthesia were 5% lidocaine, 0.75% bupivacaine, and 1% tetracaine solutions. The anesthetics used to provide epidural anesthesia were a solution of 2% lidocaine with epinephrine or 3% chloroprocaine with epinephrine. Results revealed that pain was not significantly different between the 2 anesthetic groups (P = .65); however, subjects in the epidural anesthesia group were able to ambulate (P = .008) and void (P = .02) sooner than subjects in the spinal anesthesia group. This study demonstrates that epidural anesthesia results in less urinary retention and earlier mobility than spinal anesthesia in men undergoing inguinal herniorrhaphy. Minimizing postoperative complications is essential in order for the nurse anesthetist to provide a satisfactory anesthetic experience. This study's findings suggest that epidural anesthesia optimizes recovery for the patient undergoing inguinal herniorrhaphy.
