Comparison of ropivacaine vs combination of ropivacaine and dexmedetomidine in adductor canal block for postoperative analgesia after knee surgeries

Abstract

Knee surgeries, encompassing a spectrum from arthroscopic procedures to total knee replacement, are commonly performed to address a myriad of conditions such as ligament tears, meniscal injuries, osteoarthritis, and rheumatoid arthritis. ^[1] Knee surgeries are associated with severe post operative pain. Effective pain management is crucial not only for ensuring patient comfort but also for facilitating early mobilization, minimizing complications, and expediting recovery. In recent years, adductor canal block (ACB) has been introduced as a pure sensory nerve block for postoperative analgesia following knee surgery.^[3] but also for facilitating early mobilization, minimizing complications, and expediting recovery. This study seeks to compare the efficacy, safety, and outcomes of using ropivacaine alone versus ropivacaine-dexmedetomidine combination in adductor canal block for postoperative analgesia in knee surgeries. By evaluating parameters such as pain scores, patient satisfaction, and incidence of adverse events, this study aims to provide insights into the relative merits of each analgesic regimen in the context of knee surgeries.
