This study will be carried out in neonates cared for in two settings: (i) neonatal or pediatric intensive care units and (ii) the medical regional pediatric transport system (SMUR) In the intensive care units, this study is designed as a prospective observational study to collect around-the-clock bedside data on all painful or stressful procedures performed in neonates admitted to the participating units. All 16 tertiary care centers, Neonatal Intensive Care Units (NICUs) and Pediatric Intensive Care Units (PICUs) in the Paris Region will participate. Since this is an observational study no changes in the standard of care will be carried out. During the first 14 days of admission to the participating units, prospective data will be collected on all neonatal procedures causing pain, stress, or discomfort with the corresponding analgesic therapy. 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 of endotracheal intubations will also be carried out.
