In the medical regional pediatric transport system (SMUR), neonates transported during the 2-months study period, will have all their procedures recorded in a specific data collection form. Demographic data, type of respiratory support, sedative and analgesic drugs administered concomitantly or pre-procedure, and conditions related to each procedure (type, hour of the day, operator, parental presence) will be collected. We'll also record repeat procedure attempts for procedures requiring more than one attempt before successful completion. The use of specific pre-procedural analgesia will be noted for each procedure. A real-time assessment of pain induced by each procedure will be carried out by unit staff using the DAN scale. A detailed record of conditions and neonate tolerance of endotracheal intubations will also be carried out.
