Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Evaluation of Local Anesthesia Before Arterial Puncture for Blood Gas Analysis Randomized, Control Placebo Study

Detailed Description:

In an approach of continuous improvement of the quality of the care, this project joins logically after a reflection on the treatment of pain generated by the care in the department of Pneumology 1 / septic Thoracic and vascular Cardiac Surgery.

The arterial puncture for blood gas analysis is an act with aim diagnosis which allows to study gases of the arterial blood to watch the hematosis of the patient. This act appears at the top of the anticipated care as painful by the nursing teams.

In the literature, we find no study carried out with the eutectic mixture lidocaïne prilocaïne. Other local anesthetics and other local ways of administration were estimated and the results diverge as for the efficiency of a local anesthetic for the arterial blood sample at the level radial nerve. Finally authors showed a correlation between certain factors(mailmen) and the painful character of the arterial blood sample, without defining really of population.

In this context, it is necessary to estimate the interest of a local anesthetic before arterial sampling of blood by a study randomized in insu double and versus placebo.
