Background: Local anesthetic drugs, by disrupting nerveconduction lead to a temporary numb into the specific area ofthe body. The present study was conducted to compare twodifferent anesthetics and their effect on heart rate in children.Materials & Methods: The present study was conducted on82 children age <18 years of both genders. Patients weredivided into 2 groups of 41 each. Group I received 2%lidocaine with adrenaline 1: 80000 and group II received 3%Mepivacaine. In both groups heart rate was recorded beforeand after injection and compared.Results: Out of 82 patients, males were 42 and females were40. Heart rate was 76.2 beats/ min before and 84.1 beats/ minafter injection. In group II, heart rate was 81.5 beats/ minbefore and 82.7 beats/ min after injection. The difference wassignificant (P< 0.05).Conclusion: There was more change in heart rate afterinjection of lignocaine with adrenaline, whereas mepivacainedid not alter heart rate.
