Assessment of effect of intra-articular Ropivacaine for postoperative analgesia in arthroscopic knee surgeries
Sher Singh Negi

Background: Arthroscopic knee surgery in people with degenerative knee disease is the most common ambulatory orthopaedic procedure, and the ninth most commonly performed ambulatory procedure overall. Ropivacaine causes reversible inhibition of sodium ion influx, and thereby blocks impulse conduction in nerve fibres. Hence; the present study was undertaken for assessing the effect of intra-articular Ropivacaine for postoperative analgesia in arthroscopic knee surgeries. Materials & methods: A total of 40 patients scheduled to undergo arthroscopic knee surgery were enrolled. All the patients were randomized into two study groups; Group 1 (Control Group) and Group 2 (Intra-articular Ropivacaine group). Pre-anaesthetic evaluation was done in all the patients on the evening before surgery. Complete demographic details of all the patients were obtained. Complete haematological and biochemical profile of all the patients was obtained pre-operatively. All the patients underwent arthroscopic surgeries according to their respective groups. Continuous monitoring of hemodynamic parameters was done. Postoperatively Visual analogue scale was used for evaluating the requirement of postoperative analgesia. Results: While comparing statistically, it was observed that significant higher variation in the heart rate was seen among the patients of the control group in comparison to the study group. While comparing statistically, significant results were obtained. In the present study, mean time to first postoperative analgesic requirement among the patients of control group was found to be 99.5 minutes while among the patients of the study group was found to be 241.8 minutes. While comparing statistically, significant result were obtained. Conclusion: Intra‐articular dose of ropivacaine enhanced the duration of postoperative analgesia significantly without any adverse effects. However Key words: Ropivacaine, Analgesia, Knee surgery
