Comparison of low-cost interventions for pain during radial arterial blood gas sampling in the emergency department: a three-arm randomised controlled trial
Abstract
Dear Editor,
I read with great interest the recent article by Taveekijakarn et al. evaluating the efficacy of 10% lidocaine spray and cryo-analgesia compared to standard chlorhexidine preparation for pain management during radial Arterial Blood Gas (ABG) sampling in the Emergency Department (ED).1 The authors should be commended for conducting a well-designed, pragmatic, three-arm randomized controlled trial in a high-volume ED setting, addressing a clinically relevant yet frequently overlooked issue in procedural care. [...]
