Evaluation of Efficacy of Cryotherapy for Skin Anesthesia During Arterial Puncture

Versailles Hospital200 enrolled

Overview

the purpose of this study is to evaluate the cryotherapy effect by vapocoolant spray to reducing pain during puncture for artérial blood gas

Blood gas analysis by arterial puncture is the Gold Standard in the assessment of a patient's acidbase status and oxygenation. This procedure, which can be repeated depending on the clinical condition of patient, is however associated with a potentially painful experience for patients. The known anesthetic properties of cold can be an interesting alternative to evaluate in the reduction of pain induced during arterial puncture for gas analysis in critically il patients.

Outcomes

Primary Outcomes

Pain during arterial puncture

Pain will be assessed with the visual analog scale (numeric value go 0 to 100 millimeters and representing intensity of pain from "no pain" to "worst pain imaginable"(1)

Time frame: immediately after puncture

Secondary Outcomes

Ease to performing Arterial Blood Gas (ABG) sampling

Ease to performing ABG sampling will be evaluated by i)the number of punctures necessary to obtain a sample of at least 1ml of arterial blood, ii) the delay between the first arterial puncture, and obtaining a sample.

Time frame: immediately after puncture
