Local anesthesia in hair transplantation.
BACKGROUND
Safe and effective use of local anesthesia is essential in hair transplantation.


OBJECTIVE
To review the agents and techniques of local anesthesia as applied to hair transplantation.


METHODS
Information was retrieved from texts, journal articles found by MEDLINE searches, and related references.


RESULTS
Agents, vasoconstrictors, maximum dosages, toxicity, and techniques are discussed.


CONCLUSIONS
Effective local anesthesia can be maintained throughout hair transplantation. Care must be exercised to minimize discomfort through proper technique and to minimize toxicity through judicious use of vasoconstrictors and nerve blocks and by monitoring total dosage. Constant monitoring for toxicity is required, as is early intervention in the unlikely event that warning signs should appear.
