What is going on here?

IO when IV line is not accesible or patient is obese or there is massive bleed you want iv infusion quick and also in children and its like cannula it has colors just like cannula for children its pink yellow so there is no confusion in it

Intraosseous access

Proximal tibial IO for fast infusion access.

Intraosseous infusion

🩺 Intraosseous (IO) access is an emergency vascular access technique in which a needle is inserted into the medullary cavity of a bone, allowing rapid administration of fluids, blood products, and medications when intravenous access cannot be obtained quickly. Indications Cardiac arrest Hemorrhagic or septic shock Major trauma Status epilepticus Any critically ill patient when IV access cannot be established within 60–90 seconds or after 2 failed IV attempts Common insertion sites Proximal tibia (most common in children) Proximal humerus (preferred in adults during resuscitation due to higher flow rates) Distal tibia Sternum (with dedicated devices) What can be given through IO? Crystalloids Blood products Vasopressors Epinephrine Antibiotics Calcium Any medication that can be given IV Contraindications Fracture of the target bone Previous IO attempt in the same bone within 24–48 hours Infection or burn over the insertion site Bone disorders affecting integrity (e.g., Osteogenesis imperfecta) Prosthetic joint near the insertion site Complications Extravasation Compartment syndrome Osteomyelitis (rare) Growth plate injury (children) Fat embolism (rare) Fracture High-yield facts IO access is as effective as IV access for most emergency medications. It can usually be established in under 1 minute. Conscious patients require a lidocaine flush before infusion because marrow infusion is painful. IO access is a temporary bridge and should generally be replaced with definitive IV or central venous access within 24 hours. Classic exam pearl A patient in cardiac arrest has had two unsuccessful peripheral IV attempts. The next best step is immediate intraosseous access rather than delaying resuscitation for central venous catheter placement.
