Evaluation of Efficacy of Cryotherapy for Skin Anesthesia During Arterial Puncture (SNOW)

Evaluation of Efficacy of Cryotherapy for Skin Anesthesia During Arterial Puncture for Blood Gas in Critically Ill Patients. SNOW Study

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

Study Overview

• Status: Completed
• Conditions: Cryotherapy Effect
• Intervention / Treatment: Device: Cryotherapy

Detailed 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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: cryotherapy group; cryotherapy by vapocoolant spray is applied on skin for 4 to 10 seconds ( or up to skin whitening) to 15 centimeters distance with sweeping action before ABG	Device: Cryotherapy; patients recieving cryotherapy for skin anesthesia for artérial blood gas
Placebo Comparator: control group; water spray is applied on skin for 4 to 10 seconds to centimeters distance with sweeping action before ABG	Device: Cryotherapy; patients recieving cryotherapy for skin anesthesia for artérial blood gas

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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 Outcome Measures

Outcome Measure	Measure Description	Time Frame
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
