Description
A topical anesthetic is defined as superficial loss of sensation in conjunctiva, mucous membranes, or skin, produced by direct application of local anesthetic. Gels or ointments are effective for pain relief caused by a laceration or abrasion. The duration of topical anesthesia might depend on the type and amount applied, but is usually about half an hour. The effects of topical local anesthetic agents are enhanced when the mucosal surface is dry; therefore, surfaces should be adequately dried prior to administration. Topical anesthetic agents are generally concentrated to facilitate infiltration; hence, they should be applied as a thin layer over a small area to avoid toxicity. Topical Anesthetic Cream
