Abstract

PURPOSE:

The purpose of this study was to evaluate the effectiveness of ketorolac combined with local anesthetics for anorectal surgery.

METHODS:

From June 1998 through March 1999, 123 outpatients undergoing anorectal surgery were entered into a prospective, randomized, double-blinded study involving three treatment groups. All patients received intravenous sedation consisting of fentanyl and a propofol infusion, with a local anesthesia mixture of lidocaine, bupivacaine, and bicarbonate. Group A (41 patients) received placebo (saline) injections. Group B (41 patients) received 60 mg of intravenous ketorolac at the onset of the procedure, and Group C (41 patients) received 60 mg of ketorolac mixed with the local anesthetic. Data were analyzed using analysis of variance and chi-squared tests.

RESULTS:

All groups had similar demographic characteristics and operative procedures. Twenty-nine of the 123 patients were human immunodeficiency virus-positive. There was no difference in operative or anesthesia time. Anesthesia and fluids given were similar in across groups. A significantly higher percentage of Group A patients had pain (34 percent) and required additional oral analgesia (20 percent) in the Day Surgery Unit. Only 5 percent of Group B and Group C patients complained of pain, with oral analgesics given to 2 percent of Group B and none in Group C. Voiding difficulties were more common in Group A patients, one patient requiring catheterization.

CONCLUSION:

The addition of ketorolac (60 mg), either intravenous or injected with local anesthetics, reduces voiding problems and significantly decreases postoperative analgesic requirements in outpatients undergoing anorectal surgery.
