Cardiovascular response to epinephrine-containing local anesthesia in patients with cardiovascular disease.

OBJECTIVE
The purpose of the present study was to examine the safety of epinephrine-containing local anesthesia for use on patients with cardiovascular disease.


STUDY DESIGN
Twenty-seven patients with cardiovascular disease were studied. The cardiac functional capacity of 9 patients was New York Heart Association class I; 11, class II; and 7, class III. Hemodynamic responses to intraoral injection of 1.8 mL of 2% lidocaine with 1:80,000 epinephrine were measured with impedance cardiography.


RESULTS
Systolic blood pressure and heart rate increased by 4.1% and 5.1%, respectively, immediately after the lidocaine-epinephrine injection. Consequently, rate pressure product increased by 10.0%. Cardiac index increased by 14.2%, and total peripheral resistance decreased by approximately 10%. No patient complained of cardiac symptoms. There were no significant differences in hemodynamic responses related to the extent of the cardiac functional capacity.


CONCLUSION
We concluded that lidocaine-epinephrine was safe and had few, if any, hemodynamic consequences in patients with cardiovascular disease.
