Intraoperative high-dose epinephrine infiltration in cleft palate repair.

Objective: Local infiltration of epinephrine before surgical procedures is a well-accepted technique to promote vasoconstriction. Typically, the dose of epinephrine is limited by the co-administration of local anesthetic as well as the risk for arrhythmogenesis and hemodynamic changes. In addition, some controversy exists regarding the acceptable dose of epinephrine given to children.
