Abstract

Aim:To study the post operative outcomes Adductor canal block and femoral nerve block in patients undergoing arthroscopic knee surgery with regard to their: duration of analgesia, quality of analgesia and total amount of rescue analgesia required in 24 Hrs. Methods:Sixty patients of American Society of Anesthesiology physical status I-II of both sexes, aged between 18 and 75 years, undergoing arthroscopic knee surgeries were included in this observation study conducted in the Department of Anesthesiology in Bone & Joint Hospital which is one of the associated hospital of Government Medical Collage Srinagar. After getting approval from Institutional Ethical Committee, written informed consent was obtained from all the patients before surgery. All patients were observed for 24 hr after the end of surgery. The intensity of post-operative pain was recorded for all the patients using on scale of 0-10 VAS score at 15min, 30min, 1 h, 4, 8, 12, 16 h, 24 h after surgery. Patients who reported VAS 4 or >4 were given injection Tramadol 50mg IV repeated once if required after 30 min. total analgesic consumption in 24 hrs was noted The patient’s satisfaction with the anesthetic technique was assessed on a scale of 1-5 where a score of 1 indicated strongly dissatisfaction and score of 5 strongly satisfied. Results:Visual analogue scale at different time intervals were statistically insignificantly between two study groups (Group FNB and Group ACB) p-value (p>0.05). The time to first request for analgesia ranged from 4 to 11 hours with a mean of 6.90±3.5 hours in group ACB, and 4-12 hours with a mean of 7.25±2.9 hours in group FNB. The statistical difference was insignificant among the study groups (p value >0.05). Regarding the post operative adverse effects observed among the two study groups. When compared statistically, the results were found not significant with a p value of >0.05. Conclusion:Bothadductor canal block and femoral nerve block provide good postoperative analgesia for the patients undergoing arthroscopic knee surgeries. However Adductor canal block preserved quadriceps musclestrength better than FNB, without a significant difference in postoperativepain
