Introduction: Phentanyl if one of the more used drugs to produce analgesia after its intrathecal administration, especially in association with local anesthetics. Decrease of postoperative pain is the rule of a proper evolution since it is observed that this only fact reduce problems in different organs and systems, especially in elderly patient. Objectives: To determine behavior of intradural dose of Phentanyl associated to Bupivacaine in these patients. Material and Methods: We performed a prospective observational study of index cases in 100 patients. Four groups were created including 25 patients each, proceeding as follow: Group A: no-Phentanyl. Group B: 12.5 ?g of Phentanyl. Group C: 25 ?g of Phentanyl. Group D: 50 ?g of Phentanyl. In all groups we used Bupivacaine (0.5%-7.5 mg) as local anesthetic. Variable used were: age, sex, surgery, side effects or intraoperative complications and postoperative analgesia. Results: The more frequent age group was between 60 and 70 years. There wasn't a significant difference regards sex; orthopedic surgery of lower limbs, and the urologic one were the more frequent in a similar number, side effects and complications were seen according to an increase in Phentanyl dose; pruritus, drowsiness and bradycardia had the greatest incidence. There wasn't respiratory depression, vomiting and urinary retention. Conclusions:Analgesia quality was increased according to a rise of Phentanyl dose.
