Comparative Study of Postoperative Analgesia by Spinal Anaesthesia Alone v/s Spinal Anaesthesia with Femoral Nerve Block with 0.5% Bupivacaine in Arthroscopic Anterior Cruciate Ligament Reconstruction

Objectives primary objective of this study was to evaluate postoperative analgesia in patients undergoing ACLR with spinal anaesthesia alone or combined with FNB and the secondary objectives were to assess the first analgesics request in the postoperative period in 2 group and adverse events. Method 70 patients were randomly divided into 2 groups GA (n =35) received spinal anesthesia and GB (n = 35) received spinal anesthesia and FNB. Results There was no difference between both groups regarding demographic, clinical and surgical variables. Mean pain scores were higher at 10 hours in GA, At 10 hrs in group A (total 35 patients) 21 (60 %) patients had moderate pain, 13 (37 %) patients had severe pain and 1 (3 %) patient felt mild pain while in group B (total 35 patients) 2 (5.7 %) patients had no pain, 22 (62.8 %) patients had mild pain, 8 (22.9 %) patients had moderate pain and 3 (8.6 %) had severe pain. Mean time for analgesic request in group A is 6.771.37 hrs and 10.911.93 hrs in group B. There were no serious adverse event except quadriceps muscle weakness. Conclusion in this study it is concluded that postoperative analgesia for ACLR was more effective with combination of spinal anaesthesia + FNB as compared to spinal anaesthesia alone.
