Periarticular Infiltration (Bupivacaine, Adrenaline, Magnesium Sulphate And Dexmedetomidine) For Postoperative Analgesia In Total Knee Arthroplasty- A Cases Series Study
Periarticular Infiltration (Bupivacaine, Adrenaline, Magnesium Sulphate And Dexmedetomidine)
Background: Total knee arthroplasty is a major surgery associated with severe pain and delayed rehabilitation. Good quality analgesia with minimum side effects is required for post-operative rehabilitation and influences overall outcome of patients. Material And Methods: All patients were given spinal anaesthesia. Intraoperatively, all patients received periarticular infiltration with solution of bupivacaine, adrenaline, dexmedetomidine and magnesium sulphate and normal saline. Post-operatively all patients received intravenous diclofenac sodium 75 mg 12 hourly. Postoperative pain using VAS score, sedation using Ramsay sedation score and hemodynamic parameters were observed. Result: The mean VAS score for pain was <2 during the first 48 hours and provided good analgesia to the patients. During the post-operative period hemodynamic parameters remained comparable to baseline and all patients were co-operative, oriented and tranquil. None of the patient developed any side effects. Conclusion: Local infiltration with bupivacaine, adrenaline, dexmedetomidine and magnesium sulphate can be used along with intravenous diclofenac sodium in patients undergoing total knee arthroplasty and is effective, safe and reliable multimodal pain regimen.
