ABSTRACT:
The cardiac function in a sample of cardiovascular patients was investigated by echocardiography during dental treatment using local anaesthesia . The anaesthetic used was 2% lidocaine with 1 : 100 , 000 epinephrine , which is now considered by many authors as a safe concentration . It was found at the end of the study that the cardiac output , stroke volume , heart rate , ejection fraction as well as other parameters were , unexpectedly , enhanced and increased in cardiovascular patients . These parameters were not changed in normal healthy patients . It was concluded , hence , that lidocaine 2% with adrenaline 1 : 100,000 should be used with causion in cardiovascular diseased patients .
