Hemodynamic Effects of 2% Lidocaine with 1:80000 Epinephrine in Inferior Alveolar Nerve Block

Abstract

Introduction
Lidocaine plus epinephrine is the most common anesthetic drug used in dentistry which has important cardiovascular side-effects like increase in blood pressure and cardiac arrhythmia. The goal of this study was to evaluat cardiovascular effects of one cartridge of 2% lidocaine + 1:80000 epinephrine.

Methods and Materials
60 Cases without any systemic diseases who had been admitted for right and lower molar tooth extraction were studied. For all of them, inferior alveolar nerve was blocked with one cartridge of %2 lidocaine + 1:80000 epinephrine. Blood pressure and pulse rate were measured with Omron digital sphigmomanometer (model M4) and recorded in 5 stages (At the admit time until 10 minutes after injection), and compared with together.

Results
The findings of our study showed that injection of one Cartridge of 2% lidocaine + 1:80000 epinephrine has negligible effects on blood pressure and pulse rate.

Discussion
Because of the minimum cardiovascular effects of one cartridge of %2 lidocaine + 1:80000 epinephrine in healthy cases, it seems tobe safe for patients with mild cardiovascular disease.

Key words
Epinephrine, Lidocaine, Blood Pressure, Pulse Rate.
