The standard of care for treatment of burn injury is to inject a solution of epinephrine under the skin of the injured site in order to reduce blood loss during skin grafting. This solution of epinephrine has been shown to have effects on the body outside the donor site. Some people have increases in heart rate and blood pressure. We will study the effect of a phenylephrine solution in place of an epinephrine solution to control blood loss. We think that phenylephrine will help decrease blood loss and not change blood pressure or heart rate.
