About

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

Full description

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.
