Evaluation of haemodynamic changes in hypertensive patients during tooth extraction under local anaesthesia.

Abstract

The haemodynamic changes induced by injecting 2% lignocaine with adrenaline in patients with controlled hypertension during tooth extraction is within normal range and is not different from that induced by 2% lignocaine without adrenaline. We consider it essential that all precautions to prevent inadvertent intravascular injection be undertaken by the care provider.
