Arterial Blood Gas Analysis: as safe as we think? A multicentre historical cohort study

Short summary

Arterial punctures play an important role in diagnosing and assessing an acute ill patient. Arterial blood gas analysis provide information about pH, pCO2, bicarbonate, base excess, blood sugar level, electrolytes and haemoglobin concentration. Arterial and venous punctures are usually seen as harmless interventions without serious complications. Arterial punctures are mostly done in the a. radialis, also the a. brachialis or a. femoralis are used. Research has shown that complications are rare, although serious complications can occur.


Our main aim is to describe the short (within 7 days) term complications.
