Infiltration with lignocaine and adrenaline in adult tonsillectomy

Abstract

In a trial on 84 adult patients undergoing tonsillectomy, a subcapsular injection of 10 ml 0.5% lignocaine with adrenaline [epinephrine, A] halved the blood loss and made dissection easier. A significantly higher systolic pressure and heart rate in the injected patients were thought to be due to the systemic effects of A.
