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

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6月5日 · Intraosseous (IO) access is a fast and reliable route to give medications and infusions of any type. This activity reviews IO access, explains how to place an intraosseous device, and reviews how it can be used effectively by …

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. Indications for establishing IO access include:

Tibial Interosseous IV’s Contrast injection through a tibial IO-IV. Immediate diffusion within the marrow cavity. Rapid drainage into the popliteal vein (arrow).

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.

2023年9月24日 · Humeral and tibial intraosseous (IO) vascular access can deliver resuscitative medications for out-of-hospital cardiac arrest (OHCA), however the optimal site is unclear. We examined the association between IO tibia vs. humerus as the first-attempted vascular access site with OHCA outcomes.

2023年1月5日 · 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.

Tibial IO access has the highest first-attempt success rate and the quickest time for achieving vascular access during out-of-hospital cardiac arrest when compared with peripheral intravenous...

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 .
