Blood Gas Analysis, Pain
Conditions
Brief summary
Arterial blood-gas (ABG) measurements are the gold standard to evaluate pulmonary gas exchange. However, arterial punctures are more painful than venous punctures and, in ICU patients, cause greater anxiety than tracheal aspiration. The only technique that has been shown to effectively reduce pain during arterial punctures is the subcutaneous injection of lidocaine. However, this technique is more time consuming and is poorly used. Topical anesthesia is widely used during arterial punctures despite the lack of proof of efficacy. While performing arterial punctures with small gauge needles is feasible, to the best of the investigators knowledge no studies have assessed the effect of needle gauge on arterial puncture related pain. The aim of the present study was to compare the pain experienced during arterial punctures performed with a 25 G or 23 G needle. The secondary endpoints were the characterization of the pain and the anxiety associated with the arterial punctures.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain experienced by the patient during arterial puncture | Less thant 60minutes after puncture | Evaluated using a Visual Analogue Scale for pain. Graduated from 0 to 100mm |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Anxiety before and after puncture arterial puncture | Before puncture and less than 60minutes after puncture | Evaluated using a Visual Analogue Scale for anxiety. Graduated from 0 to 100mm |
| Most painful moment of the arterial puncture | Less than 60minutes after puncture | Evaluated by a standardised questionnaire: The most painful moment was : A/ At needle insertion B/ During puncture C/ After puncture D/ While the puncture was repeated |
| Duration of arterial puncture | 10minutes | Time needed to perform the procedure will be evaluated using a chronometer. The number of seconds needed to collect the arterial blood gas will we recorded. |
