Abstract

PURPOSE: The aim of this study was to evaluate the effectiveness of local anesthesia compared to spinal anesthesia and the usefulness of pentothal induction before infiltration of a local anesthetic agent.
METHODS
A concurrent non-randomized prospective study was conducted on 52 patients who underwent a hemorrhoidectomy. For the spinal anesthesia (SA) group (n=29), 0.5% heavy bupivacaine (Marcaine(R)), 5 mg (1 ml), was used, and for the local anesthesia (LA) group (n=23), pentothal, 3.3 mg/kg, was administrated intravenously prior to infiltration of a mixture of local anesthetics (2% lidocaine, 14 ml, with 0.5% bupivacaine, 7 ml).
RESULTS
There were no differences between the two groups in terms of operating time, postoperative pain, headache, urinary difficulty, nausea or vomiting, pain-free interval after operation, analgesic requirements, and patient's or surgeon's satisfaction. Postoperative ambulation was earlier in the LA group than in the SA group.
CONCLUSIONS
Local anesthesia after pentothal induction can be used effectively for a hemorrhoidectomy and may be a safe alternative to spinal anesthesia.
