Effect of pre-operative anxiolysis on postoperative pain response in patients undergoing total abdominal hysterectomy.
In a double blind, placebo-controlled trial, we have assessed the effects of pre-operative anxiolysis on postoperative pain scores in 112 ASA I-II women, aged 18-65 years, scheduled to undergo total abdominal hysterectomy. Subjects were randomly allocated to receive either oral diazepam 10 mg (n=56) or placebo (n=56) pre-operatively. Postoperative anxiety, pain scores, analgesic consumption, and sedation were evaluated at several time points during the first 24 h following surgery. Postoperative pain scores were found to be significantly higher in the diazepam group. Trait and state anxiety showed a significant effect on pain scores, independent of the treatment group. No difference was found between the groups in morphine consumption, but there was a significant reduction in morphine consumption with time.
