Infiltration with lignocaine and adrenaline in adult tonsillectomy

In a trial of 84 adult patients undergoing tonsillectomy, a subcapsular injection of 10 mls 0 . 5 per cent lignocaine with adrenaline 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 adrenaline.
