Brief Summary
Intraarterial cannulation is important for continuous blood pressure monitoring and blood gas analysis throughout the surgical procedure and in intensive care patients. Ultrasonography (USG) has gained popularity in vascular cannulations and facilitates intraarterial interventions. Radial artery is one of the most preferred arteries. Our aim in this study is to compare proximal and distal radial artery cannulations by USG in terms of procedural success, procedure time and complications.
