Ultrasound Guided Arterial Puncture

Ultrasound Guided Arterial Puncture: a Prospective, Blinded, Randomised Controlled Trial.

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
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

Outcome Measure	Measure Description	Time Frame
Time used for arterial puncture		up to 1 hour after arterial puncture
Patient corporation	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.	up to 1 hour after arterial puncture
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
