Background: Moderate to severe pain develop after knee surgery results prolong hospital stay and delay return to normal daily activities. Various analgesic modalities have been used for postoperative analgesia in patients undergoing knee surgery. Both femoral nerve block (FNB) block and fascia iliaca compartment block (FIB) are used routinely for postoperative pain relief in patients undergoing knee surgery. Objectives: To compare the efficacy of postoperative analgesia of FNB & FIB in postoperative period among patients undergoing knee surgery under sub- arachnoid block. Methods: This Randomized Clinical Trial was performed in Combined Military Hospital (CMH), Dhaka from July 2020 to December 2020. Forty patients scheduled for routine knee surgery under sub-arachnoid block belonging to ASA class I, II and III were included in the study and randomly divided into two groups with 20 patients in each group. At the end of surgery, In Group A (n= 20) femoral nerve block was employed & in Group B (n=20) fascia iliaca compartment block was employed. Results: Significant relief of pain occurred in recovery room in group B than group A (3.67±0.802 vs 4.3±0.877; p<0.05). This improvement was noticed in group B at 6 and 24 hours follow up (p<0.05 in all follow up). Post-operative analgesic consumptions was also lower in group B at 1, 12 & 24 hours follow up (p<0.05 in all follow up). Demographic characteristics were similar across the two groups in terms of age, sex, BMI and ASA grading (p>0.05 in all cases). No significant difference was noted in both pre-operative, post-operative and recovery room heart rate (p>0.05) and mean arterial pressure (p>0.05). Complication was similar in both groups. Conclusion: Fascia iliaca compartment block (FIB) for management of post-operative analgesia in knee surgery is more effective than femoral nerve block (FNB).
