This study aims to improve the safety and quality of **tracheal intubation** (placing a tube into the windpipe to help someone breathe) in children who are in intensive care units (ICUs) or emergency departments (EDs). These procedures can be risky and may have serious consequences. The study will look at how these procedures are done in different hospitals and compare them through a network called **NEAR4KIDS**. By collecting and comparing this data, the study hopes to make these procedures safer.

**Eligibility:** The study includes cases where children of any age need advanced airway procedures in the pediatric, cardiac, or neonatal ICUs, delivery rooms, or EDs. This includes putting a tube in their windpipe, placing a special mask, or emergency surgeries to open the airway. It does not include procedures in operating rooms.

• The study aims to improve care for children needing advanced airway procedures.
• It involves collecting and comparing data from multiple hospitals.
• Children receiving these procedures in operating rooms are not part of this study.
