Efficacy of Adding Clonidine to Bupivacaine 0.25% Versus Plain Bupivacaine 0.25% Infiltration in Scalp Blocks for Supratentorial Craniotomy.

Background Scalp blocks help attenuate hemodynamic responses and provide analgesia in neurosurgical procedures. Clonidine, an alpha-2 agonist, has been known to enhance the duration of analgesia when used as an adjuvant in peripheral nerve blocks. Our aim was to evaluate the efficacy of adding clonidine 2 mcg/kg to bupivacaine 0.
