Ultrasound Guided Arterial Puncture

Not Applicable

Completed

• Conditions: Arterial Puncture
• Interventions: Procedure: Ultrasound guided arterial puncture; Procedure: Conventional arterial puncture technique

• Registration Number: NCT01660724
• Lead Sponsor: Odense University Hospital

Brief Summary

The main purpose of the study is to evaluate whether the routine use of ultrasound guided arterial puncture can increase the proportion of patients who only needs one puncture attempt in order to successfully extract enough blood to make an arterial blood gas analysis, when ultrasound guided arterial puncture is compared to conventional arterial puncture technique.

Arm && Interventions

Group	Intervention	Description
Ultrasound guided arterial puncture	Ultrasound guided arterial puncture	Patients randomised to the this arm has arterial puncture performed using simultaneously ultrasound in order to guide the passage of the syringe from the patient's skin to the artery
Conventional arterial puncture technique	Conventional arterial puncture technique	Patients randomised to the active comparator arm has arterial puncture performed using the conventional technique

Primary Outcome Measures

Name	Time	Method
The proportion of patients who only needs one puncture attempt in order to successfully extract enough blood to make an arterial blood gas analysis	up to 1 hour after arterial puncture

Secondary Outcome Measures

Name	Time	Method
Time used for arterial puncture	up to 1 hour after arterial puncture
Patient corporation	up to 1 hour after arterial puncture	Patient corporation is subjectively estimated by the physician performing the arterial puncture. The degree of patient corporation are assessed on a scale from 1 - 5, where 1 is very poor patient corporation and 5 is perfect patient corporation.
Pain Scores on the Visual Analog Scale	Up to 1 hour after arterial puncture
Number of attempts before successfully acquiring arterial puncture	up to 1 hour after arterial puncture
