Randomized Controlled Trial
Ethyl chloride spray, a local anesthetic in arterial blood gas sampling: A randomized, controlled, double-blinded study.
Arterial blood gas sampling provides useful information on respiratory parameters and acid-base balance. However, this procedure is painful and uncomfortable for the patient. Therefore, this study aimed to examine the analgesic efficacy of ethyl chloride spray compared to a placebo during radial artery blood gas sampling. ⋯ Ethyl chloride spray has analgesic efficacy in arterial blood gas sampling. Therefore, the use of this spray provides an analgesic effect on patients during arterial blood gas sampling performed in the emergency department.
