Comment to On-demand use of peripheral arterial catheters outside the Intensive Care Unit: Development and retrospective evaluation of an internal protocol for insertion and management

To the authors knowledge, this is the first article describing the insertion and management of ACs for on-demand utilization outside the intensive care unit. The safe and effective use of this technique could be clinically relevant in patients requiring multiple ABG without need of invasive monitoring; it also allows the reduction of both artery sticks and workload of health care providers. However, clinical studies are needed to confirm the validity of the proposed treatment, especially the use of the most appropriate securement system and the most effective solution for locking catheters.
