A Randomized Controlled Trial on the Effect of Needle Gauge on the Pain and Anxiety Experienced During Arterial Puncture

Not Applicable

Completed

• Conditions: Blood Gas Analysis; Pain
• Interventions: Procedure: 25Gauge; Procedure: 23Gauge

• Registration Number: NCT02320916
• Lead Sponsor: University Hospital, Rouen

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.

Arm && Interventions

Group	Intervention	Description
25Gauge	25Gauge	Arterial blood puncture will be performed using a 25Gauge needle
23Gauge	23Gauge	Arterial blood puncture will be performed using a 23Gauge needle

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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.
