For how long can an intraosseous (I/O) access be maintained?

Intraosseous (I/O) access is a critical procedure used in emergency situations to provide rapid vascular access, particularly when traditional intravenous (IV) access is difficult or impossible. The correct duration for maintaining an intraosseous access is up to 24 hours. This time frame is based on the understanding of the physiology of bone marrow, where the intraosseous needle is inserted.

Maintaining I/O access for 24 hours is considered a safe and effective window, allowing for the administration of necessary fluids and medications while minimizing the risk of infection or complications associated with prolonged use. After this period, the intraosseous access should be reassessed, and if ongoing vascular access is required, it is often transitioned to a more stable form such as a peripheral or central line.

Understanding the limitations on the duration of intraosseous access is crucial for patient safety and effective management in emergency settings.
