Abstract

Due to the lack of motor sparing in adductor canal block and the analgesic effects postoperatively being on par with those of femoral nerve block, it is now regarded as a worthy substitute for femoral nerve block after knee surgeries. In this study, we tested the effectiveness of these 2 commonly used blocks by administering a standard dose of local anaesthetics to patients undergoing all knee surgeries, randomly assigning them to 2 groups, administering one block to each group, and monitoring the quadriceps' motor function and postoperative analgesia in both groups. Materials and Method: Study was done on sixty patients divided into two groups (FN and AC) randomly after getting clearance from Institutional Ethics Committee. For both blocks, 15ml of 0.5% Bupivacaine with 5ml of Epinephrine was given. Demographics of each patient, hemodynamic data recorded intraoperatively, pain score (VAS score), muscle power grading, rescue analgesia and complications were noted and statistically analyzed using various tests. Results: 60 patients in two groups- 30 in FN and 30 in AC were evaluated at T4, T5, T6 hours for FN were 3.80, 4.81, 5.6 and AC were 3.91, 5.87, 6.2 (p=0.001, 0.001, 0.032). VAS, rescue analgesia, patient satisfaction were not significant. Conclusion: Adductor canal block showed significant higher grade of strengthening of quadriceps muscle than femoral nerve block postoperatively in 4th, 5th and 6th hour.
