Postoperative pain is a special type of acute pain of a great repercussion in the health sector. Its optimal control in proctologic procedures and of perineum is a real challenge. Its appropriate treatment may to relief suffering allowing an early mobilization and to shorten the hospital stay. Objectives: to identify the usefulness of opioids in postoperative surgery in proctologic anesthesia. Method: A prospective, comparative, double blind and experimental study was conducted to choice the dose of intrathecal morphine to be used for postoperative analgesia in patients underwent proctologic surgery in the Service of Anesthesia and Resuscitation of the "Dr. Salvador Allende" Clinical Surgical Teaching Hospital during 2009. Sample included 210 randomized patients divided into three groups according the dose of morphine administered: I Group (74 patients) received 3 µg/Kg; II Group (68 patients) received 4 µg/Kg and III group (68 patients) received 5 µg/Kg. Results: The mean value in hours of analgesia length in I group was of 11,97 ± 1,67 DS, in the II group it was of 21,54 ± 2,29, and in the III group, it was of 21,4 ± 2,03. Pruritus had the higher incidence as adverse effect, followed by urinary retention, nauseas and vomiting. Conclusions: Dose of 4 µg/Kg seems to be the more recommendable for the postoperative analgesia using intrathecal morphine in proctologic surgery if we take into account the analgesia length and the adverse effects found in our study.
