Topical Anaesthesia to Reduce Pain Associated with Carpal Tunnel SurgeryFrom the Department of Orthopaedics, Kings Mill Hospital, Sherwood Forrest Hospitals NHS Trust, Nottinghamshire, UK Correspondence: Dr TM Lawrence, Flat 15, Dukes Wharf, Wharf Road, Castle Boulevard, Nottingham, NG7 1FX, UK. Tel.: +44-1159123662; E-mail: tomlawrence75{at}hotmail.com This randomized, double-blinded study assessed the effectiveness of a topical anaesthetic, eutectic mixture of local anaesthetics (EMLA), in reducing pain associated with carpal tunnel release performed under local anaesthetic. Fifty-six patients undergoing carpal tunnel release under local anaesthetic were randomized into either EMLA (n=29) or placebo (n=27) groups. Visual analogue pain scores were obtained for needle insertion, injection of anaesthetic and surgery itself. Pain scores were significantly less for needle insertion (P=0.001) and injection of anaesthetic (P=0.0005). Scores related to surgery were also lower in the EMLA group, but this did not reach statistical significance.
