Intraosseous infusion (IO) is the process of injecting medication, fluids, or blood products directly into the bone marrow; [1] this provides a non-collapsible entry point into the systemic venous system. [2] The intraosseous infusion technique is used to provide fluids and medication when intravenous access is not

2023年6月5日 · Intraosseous (IO) vascular access refers to the placement of a specialized hollow bore needle through the cortex of a bone into the medullary space for infusion of medical therapy and laboratory tests.

2025年3月4日 · The intraosseous (IO) device is a life-saving tool used to provide rapid vascular access in emergency situations. It is a safe and effective technique for infusing medications, fluids, and blood products in critically-ill individuals who do not have a peripheral IV line.

This topic will discuss intraosseous (IO) infusion in children and adults, including indications, contraindications, and techniques according to device. Other forms of venous access are discussed separately:

Intraosseous (IO) access can be obtained using manual or drill-inserted devices for insertion of specialised needles; IO access uses the medullary space as a non collapsible entry point into the systemic venous system

2023年1月5日 · IO access has higher first-attempt success rates than IV access in cardiac arrest. Of IO sites, the tibial IO site is associated with the least number of complications. Pharmacokinetics of drugs comparable when administered IO versus IV.

2023年8月20日 · Intraosseous access (IO access) involves inserting a catheter into the medullary space of a long bone, providing access to the systemic vasculature. Like intravenous access, IO medications can bypass first-pass metabolism and have maximum bioavailability.

Intraosseous (IO) vascular access can be life-saving. Though more expensive than intravenous (IV) catheters, emergency response teams should have access to and training on using IO access devices.

IO infusion is a rapid and safe method for obtaining parenteral access in patients with difficult venous access. Pioneered in 1922 by Drinker and colleagues [4], this access was not used to benefit peripheral IV until the 1980s.

2024年11月7日 · Intraosseous (IO) devices—inserted by punching a needle loaded on a trocar into the tibia or femur—can be placed more easily than IV catheters, leading to faster injection of epinephrine. On the other hand, infusion speed and distribution of epinephrine into the systemic circulation might be slower with intraosseous delivery.
