Tissue Necrosis as a Rare Complication of Local Anaesthesia - A Case Series

Lignocaine, amongst all the local anaesthetic agents, is the most common agent used in dentistry and in the field of oral surgery. Local anaesthesia is very effective, safe and simple to use. Rare complications related to it are reported.

We present a case series of patients with sloughing and necrosis of tissue allegedly caused due to administration of contaminated local anaesthesia. All the patients had a history of extraction by same practitioner at same time duration and centre.

The patient was diagnosed with post-anaesthetic tissue necrosis.

All the cases presented in this report were managed conservatively.

On 2-month follow-up, the lesion healed and was replaced by healthy tissue.

Risk factors should be well assessed and precautions must be taken before administration of lignocaine to avoid the adverse outcome.
