Increasing the Safety Profile of Follicular Unit Extraction by Eliminating the Use of Bupivacaine and Nerve Block: Experience from a Tertiary Care Center of North India

INTRODUCTION: Follicular unit extraction (FUE) is a safe and effective procedure in the hands of an expert. Side effects, particularly those which can lead to significant morbidity or mortality, are unacceptable as the procedure is done purely for cosmetic reasons. Any modification that decreases the risk associated with the procedure should be promoted. AIM AND OBJECTIVE: The study was conducted to determine whether FUE can be carried out effectively with the elimination of nerve blocks and bupivacaine from the procedure. MATERIALS AND METHODS: The study was conducted in 30 patients suffering from androgenetic alopecia. The donor areas was anesthetized using lignocaine with adrenaline just below the area to be harvested. The anesthetic was injected intradermally resulting in the development of wheals in continuity, forming a linear line. From our previous experience, we found intradermal administration of lignocaine to give better anesthetic effect as compared to subcutaneous administration, although the former is more painful. This was followed by injection of tumescent into the donor area and donor harvesting, which lasted for a couple of hours. The recipient area was anesthetized using a similar technique of linear injection of anesthetic just ahead of the proposed hair line. RESULTS: The total amount of lignocaine with adrenaline consumed during the surgery ranged from a minimum of 6.1 ml to 8.5 ml, with an average of 7.6 ml. The average duration of the entire surgery was 6.5 h, ranging from 4.5 to 8.5 h. None of the patients experienced any pain during the entire surgery, and there were no significant side effects related to anesthetic administration in any patient. DISCUSSION: We found lignocaine with adrenaline to be a very safe and effective anesthetic agent for field block anesthesia in FUE. The exclusion of bupivacaine and nerve blocks from the procedure of FUE can further increase the safety of the procedure, particularly for beginners and in cases where the area to be covered is not extensive (Norwood–Hamilton grades 3, 4, and 5).
