Arterial Puncture
Conditions
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.
Interventions
PROCEDUREUltrasound guided arterial puncture
Arterial puncture is performed using simultaneously ultrasound in order to guide the passage of the syringe from the patient's skin to the artery
PROCEDUREConventional arterial puncture technique

Design outcomes
Primary
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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 | — |
