Children undergoing intrahospital transport are at risk for adverse events. This study used perioperative adverse event data reported to a patient safety organization to identify pediatric anesthesia transport-associated adverse events. A small proportion (5%) of pediatric anesthesia adverse events were associated with transport, but the majority of events were deemed preventable and one-third resulted in patient harm. Cardiac arrest and respiratory events occurred most frequently and largely affected very young children (<6 month). A previous WebM&M discussed a perioperative respiratory event in a pediatric patient during intrahospital transport.
