RESUMO
Introduction: Pain is a complex subjective sensation that is difficult to quantify in a repeatable manner. Surgical pain is observed to be more intense post-surgery and then fades in the next 24 h. Epidural anesthesia/analgesia is the most widely used technique for lower limb surgeries because of its good sensory and motor block property, reduces stress response, and maintains sufficient spontaneous respiration and hemodynamic stability. Materials and Methods: The study looked at 100 individuals between the ages of 20 and 60 who underwent elective lower limb surgery and were classified as ASA I and II. The patients were split into two 50-person groups. The adverse effects of nausea, vomiting, respiratory depression, urine retention, and pruritus, as well as the quality and duration of postoperative analgesia, were investigated. The patient was monitored for 48 h after surgery. Results: A total of 100 patients were included in the study, where the least age of the patient was 19 years and the greatest age was 75 years. In group T, maximum patients belong to the age group of 26–35 years, whereas in group F maximum patients belong to the age group of 36–45years. In group T, 41 (82%) were males and 9 (18%) were females. In group F, 37 (74%) were males and 13 (26%) were females. Conclusion: Our findings show that epidural tramadol and epidural fentanyl are equally effective, except for fentanyl’s shorter duration of action. Fentanyl also has a moderate sedative effect, which is beneficial in the postoperative period.
