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.

Randomized Controlled TrialPain perception during transabdominal chorionic villus sampling: a randomized trial comparing topical ethyl chloride anesthetic spray and lidocaine injection.
Background: Chorionic villus sampling is an important invasive procedure used for early antenatal genetic testing that can be associated with anxiety and fear of pain. Pain analgesia prior to chorionic villus sampling can be offered with subdermal lidocaine; however, lidocaine injection itself is associated with pain. Our objective was to determine whether administration of topical ethyl chloride anesthetic spray is associated with decreased pain perception during transabdominal chorionic villus sampling compared to 1% lidocaine subdermal injection. ⋯ There was no significant difference in pain scores before or after the procedure. Conclusion: During transabdominal chorionic villus sampling procedures, topical ethyl chloride anesthetic spray is associated with a higher distribution of pain scores as compared to 1% lidocaine subdermal injection, which suggests higher levels of pain. Clinical trial registration: This trial is registered with clinicaltrials.gov (NCT03140293). https://clinicaltrials.gov/ct2/show/NCT03140293?term=NCT03140293&rank=1.
