Randomized Controlled Trial
Evaluation of haemodynamic changes in hypertensive patients during tooth extraction under local anaesthesia.
This study was conducted to determine the changes in blood pressure and the pulse rate of patients with controlled hypertension having dental extraction under local anaesthesia utilizing 2% lignocaine with adrenaline, and to evaluate whether these changes in blood pressure were are attributable to addition of adrenaline. ⋯ 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.
