عنوان انگلیسی Comparative Study of Dexmedetomidine versus Fentanyl as an adjuvant to Ropivacaine (0.75%) in Epidural Anaesthesia in Lower Limb Orthopaedic Surgery
چکیده انگلیسی مقاله Background: Dexmedetomidine and Fentanyl both possess hypnotic, sedative, analgesic properties and have been utilised as an additive in epidural anaesthesia. The purpose of this study is to compare the sedative and analgesic effects of Dexmedetomidine and Fentanyl when added epidurally with Ropivacaine (0.75%) during lower limb orthopaedic surgery. Methods: The study comprised of 60 patients, both male and female, aged 18 to 60, who had ASA classification I or II for tibia fibula surgery. Two groups of patients were split up at random: Group RD contains– Ropivacaine (0.75%) 15ml + Dexmedetomidine (1microgm/kg) 0.5ml + 0.5ml sterile water (Total volume-16ml) and Group RF - Ropivacaine 15ml (0.75%) + 1ml Fentanyl (1microgm/kg) (Total volume-16 ml). The epidural space was maintained 4 cm within and situated between L3 and L4 space. Investigations were conducted on parameters such as sensory and motor block features, sedation score, hemodynamic factors and pain assessment. Using the student `t` test, statistical analysis was performed using STATAIC13 software. Results: Onset of sensory analgesia at L1 and Complete sensory and motor blockage occurred much earlier in the RD group. Higher sedation scores and significantly prolonged postoperative analgesia was observed in RD group. Conclusion: Dexmedetomidine is a safer and more effective epidural adjuvant than fentanyl because it provides stable hemodynamics, extended post-operative analgesia, early onset and development of sensory and motor effects and sedation.
