Comparative Analysis of Fentanyl and Dexmedetomidine as Adjuvants With Lignocaine in Intravenous Regional Anesthesia for Upper Limb Surgeries

Abstract

Bier's block, or intravenous regional anaesthesia, is typical for upper limb surgery. Tourniquet discomfort remains a major issue with IVRA, hence adjuvants should be investigated to increase patient satisfaction and comfort. Fentanyl and dexmedetomidine are compared in IVRA for upper limb procedures in this study. A randomised controlled trial included 55 elective upper limb surgery participants. Patients were randomised to Group B (lignocaine and dexmedetomidine) or Group A (lignocaine and fentanyl). Analgesia quality, tourniquet pain, postoperative pain, time to obtain analgesia, and total consumption were assessed. In this study, both adjuvant combinations entanyl plus Lignocaine or dexmedetomidine and Lignocaine—provided excellent or good anaesthesia in most patients (84 percent in Group A and 76 percent in Group B). Group A had less tourniquet pain (mean 1.8) than Group B.
