ABSTRACT

Introduction, definition, rationale and scope Dermatosurgery and Cosmetic dermatology procedures are being performed by increasing number of dermatologists. Most dermatosurgeries are performed in an outpatient setting and as day care surgeries, under local anesthesia. Hence, it is important to improve patient comfort during all procedures. These guidelines seek to lay down directives in the use of local anesthesia, outline the different local anesthetics, the mode of administration, complications arising out of such procedure and management of the same. Facility for administration of local anesthesia Local anesthesia is usually administered in the dermatologist's procedure room. The room should be equipped to deal with any emergencies arising from administration of local anesthesia. Qualifications of local anesthesia administrator Local anesthesia administrator is a person who applies or injects local anesthetic agent for causing analgesia. Procedures done under local anesthesia are classified as Level I office procedures and require the administrator to have completed a course in Basic Cardiac Life Support (BCLS). Evaluation of patients for topical or infiltrative anesthesia Details of patient's past medical history and history of medications should be noted. Allergy to any medications should be specifically enquired and documented. Patients for tumescent anesthesia need additional precautions to be observed as described in these guidelines. Methods of administration of local anesthesia Different methods include topical anesthesia, field block, ring block, local infiltration and nerve block. Also, it includes use of local anesthetics for anesthetizing oral and genital mucosa. Tumescent anesthesia is a special form of local anesthesia used in liposuction and certain selected procedures. Local anesthetic agents Different local anesthetics are available such as lignocaine, prilocaine, bupivacaine. The dermatologist should be aware of the onset, duration of action, side effects and drug interactions of these agents. Side effects of local anesthetics Various local and systemic side effects and complications arising from administration of local anesthetics have to be timely recognized and treated effectively. Skin testing prior to administration of local anesthetic is recommended.
