Abstract

The pain after a hemorrhoidectomy is widely feared by many patients who are mostly still treated with oral/intramuscular narcotics to control their pain postoperatively. In an effort to decrease posthemorrhoidectomy pain by applying newer methods of analgesia, a prospective trial was conducted to investigate the postoperative analgesic effect of Tarasyn(R) (ketorolac tromethamine) injected into the internal sphincter muscle at the time of the hemorrhoidectomy. Tarasyn(R) is a nonsteroidal anti-inflammatory drug introduced for intramuscular injection to control postoperative pain. It's action is peripheral. Therefore, it seems appropriate to inject it directly into the anal sphincter muscles when these are exposed during anorectal procedures. A total loading dose of 60 mg(2 cc, 30 mg/ml) of ketorolac was used intraoperatively. It was injected intramuscularly locally after completion of hemorrhoidectomy. Postoperative pain after a hemorrhoidectomy can be safely controlled in a patient by using newer methods of pain control, including supplemental use of the nonsteroidal analgesic ketorolac, which allows early release of the patient, the day of surgery by diminishing the postoperative pain in our study group. Another important advantage of a local injection of ketorolac was the elimination of urinary retention.
