Background and Aim: Patients with femur fractures need a simple, easily accessible regional nerve block that can be performed supine without patient movement. Quadratus lumborum, femoral nerve, and fascia iliaca compartment blocks are the main methods. Dexmedetomidine will be tested in a fascia iliaca compartment block to position femur fracture patients before spinal anesthesia. Material and Methods: This study compared the analgesic effects of Bupivacaine plain and Dexmedetomidine in Fascia iliaca compartment block before spinal anesthesia in fracture femur surgery patients. Patients were split into two groups: Group A patents (n=37): 40 ml, 0.25% inj. Plain and injected Bupivacaine. In FICB, progressive injections of 1μg/kg body weight dexmedetomidine were given after a negative aspiration test. Group B patents (n=37): 40 ml, 0.25% inj. Bupivacaine plain was progressively infused after a negative FICB aspiration test. Fentanyl total, onset time to sensory block, number of patients requiring IV Fentanyl. Requirement, Start with rescue analgesia. Total rescue analgesia needed in 24 hours and baseline, positional, and postoperative VAS values were recorded. Results: The mean onset time to sensory block (min) was 13.29 ± 2.05 in Group A and 17.83 ± 1.04 in Group B. (P <0.001) Group A had a mean Fentanyl need of 34µg, while Group B had 38µg (P > 0.05). There was no significant difference in Mean EOSP Score between Group A (2.32 ± 0.47) and Group B (1.86 ± 0.54). (P > 0.05) Group A had a substantially longer time to first analgesic request (8.02 ± 1.21) than Group B (5.27±0.65). (P < 0.001). Conclusion: Dexmedetomidine (1µg/kg) to 0.25% Bupivacaine improves FICB onset and reduces discomfort during spinal anesthesia for elective orthopaedic procedures.
