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 available or not feasible.

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 · An intraosseous (IO) device is a life-saving tool used to provide rapid vascular access in emergency situations where intravenous (IV) access cannot be obtained or is likely to delay treatment. The IO device consists of a hollow-bore needle that is placed through the cortical bone and into the medullary canal with the aid of an assisting device.

When intraosseous access (IO) is the best option for vascular access, clinicians and emergency care professionals rely on the BD ® Intraosseous Vascular Access System—the confident choice for delivering fluids and medications safely during …

2023年1月5日 · Survival outcomes are, at best, comparable in OHCA patients who receive IO vs IV access. Intraosseous vascular (IO) access is an established rapid, safe, and effective alternative for peripheral intravenous drug delivery. The AHA recommends IV as preferred site of access; however, if unable to obtain IV access, then IO access is acceptable.

When IV access cannot be achieved, IO access is safe, reliable, and quick. It can be accomplished in 30 to 60 seconds and even faster with an IO gun. This is especially helpful in pediatric emergencies when time is critical.

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

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: (See "Emergency and elective venous access in children" and "Peripheral venous access in adults".)

Intraosseous (IO) delivery of emergency medications during cardiac arrest provides safe and rapid access when intravenous (IV) injection is not available 1–4. The American Heart Association and European Resuscitation Council present IO access as an acceptable alternative during resuscitation when peripheral intravenous (PIV) access is ...

The IO access allows rapid fluid administration to provide the required volume resuscitation in patients in shock. The IO flow rate may reach up to 150 mL/min in either the tibial or humeral route when the pressure bag is inflated up to 300 mm Hg .
