Clinical Trial Summary

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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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)	immediately after puncture
Secondary	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.	immediately after puncture
