ObjectiveWe compared the effectiveness of nerve blocks (regional anaesthesia, [RA]) versus local anaesthesia (LA) to treat face and hand wounds. Emergency physicians who had not previously used nerve blocks administered the anaesthesia based on anatomic landmarks.MethodsThis prospective observational open study was conducted at a military teaching hospital emergency department (ED) between May 1, 2013 and January 31, 2014. All patients requiring treatment of facial or hand wounds were included. The primary outcome was anaesthesia effectiveness 15minutes post-administration. We also recorded the number of injections sites, injected volume, pain of administration, operator comfort, and complications. Lidocaine anaesthesia without epinephrine was used.ResultsOf the 1090 treated patients, 617 patients were included in the analysis: 316 with hand wounds and 301 with facial wounds. Overall, 130 wrist blocks and 63 facial blocks were performed. RA effectiveness was comparable to that of LA: for facial wounds, RA=88.9% versus LA=89% (P=0.86); for hand wounds, RA=82.2% versus LA=90.1% (P=0.15). RA groups had significantly fewer injections than the LA groups, and less anesthetic was injected in the facial RA group. The pain of anaesthesia administration and operator comfort was similar. There was no complication during the 9-month data collection period.ConclusionFacial and wrist nerve blocks are easy to administer and as efficient as local infiltrations, plus they require fewer injection sites, and, for facial RA, less anesthetic. Their teaching and use should be more widespread in EDs.Copyright © 2018 Société française d'anesthésie et de réanimation (Sfar). Published by Elsevier Masson SAS. All rights reserved.
