Flow Rate Considerations for Intraosseous Catheter Use

AbstractPurpose of ReviewThis review is intended to familiarize the clinician with considerations relevant to the expected flow rates associated with the clinical use of intraosseous (IO) infusion catheters. Relevant concepts include site of intraosseous insertion, device used, type and amount of infusion pressure provided, and complications that may affect flow through the IO device.Recent FindingsIntraosseous cannulation is increasingly used to provide emergent vascular access for patients with difficult vascular access, especially in situations when peripheral venous access is not readily available. Recent studies have focused on the various flow rates achievable at different anatomic insertion sites, especially at the proximal humerus, sternum, and proximal tibia sites. However, these rates may be influenced by a variety of factors, many of which are discussed in this review.SummaryThe flow rate achievable for fluids and medications through an intraosseous catheter varies widely, depending upon the device used, anatomic insertion site selected, type of medication or fluid being infused, and other features of the infusion kit. Clinicians should be familiar with the flow rates typically achievable with IO infusion devices, as well as factors that may influence the rate of flow realized with various fluids and medications.
