Topical anaesthesia for repair of minor lacerations

One hundred traumatic skin wounds were sutured under topical anaesthesia using a solution of lignocaine, adrenaline, and cocaine, and the effectiveness of the anaesthesia produced was assessed on a behavioural scale. The procedure was tolerated well by 63 patients, poorly by 11, and in 26 the response was uncertain. The response correlated well with age and with the field of anaesthesia measured from the wound margin. No toxic reactions were observed.
