A COMPARATIVE STUDY OF DEXMEDETOMIDINE AND MAGNESIUM SULFATE AS ADJUVANTS WITH ROPIVACAINE FOR SPINAL ANAESTHESIA IN INFRAUMBILICAL SURGERIES AND POSTOPERATIVE ANALGESIA

Abstract

Background Neuraxial anaesthesia is the most preferred technique for lower abdominal and lower limb surgeries. Dexmedetomidine is an agonist on the α2receptor found in the peripheral and central nervous system. Stimulation of the alpha receptors in the brain and spinal cord inhibits neuronal firing, causing hypotension, bradycardia, sedation, and analgesia
