Local anesthetics.
Emergency physicians often rely on the use of local anesthetic agents to relieve patient discomfort, and research continues in an effort to develop new agents with improved anesthetic qualities. Eventually, a nontoxic, rapidly acting agent may become available that could provide profound anesthesia of long duration when applied topically to intact skin or wounds. Until the "perfect" agent is developed, physicians can help the patient by making knowledgeable choices regarding local anesthetic techniques. By choosing topical agents when appropriate and buffering agents to be infiltrated, using courteous techniques of injection, and being cognizant of potential adverse reactions, the physician can turn a potentially unpleasant and frightening situation for the patient into a positive experience that promotes satisfaction and cooperation.
