Neonatal resuscitation

Did You Know?

• Face masks covering the infant's mouth and nose are often used in resuscitation; nasal prongs, tubes, masks, and laryngeal mask airway devices are also sometimes used.
• Birth asphyxia, a dangerous condition of oxygen deprivation, may begin before birth if the umbilical cord is compressed or tears during delivery.
• One serious complication of hypoxic damage is a brain injury known as neonatal hypoxic-ischemic encephalopathy.

Uses

Up to 10% of infants are born needing assistance to begin breathing, and after help many start on their own and are healthy. Breathing problems at birth are a high-priority emergency. Infants who are gasping, apnoeic, or have bradycardia with a heart rate below 100 beats per minute after birth should receive positive pressure ventilation using a manual ventilation device such as a self-inflating bag or a T-piece.

Training and certification

The most widely known certification is the Neonatal Resuscitation Program (NRP), started by the American Academy of Pediatrics. The course is offered to anyone involved in neonatal resuscitation, including nurses, physicians, respiratory therapists, and certified nursing assistants. It comprises 11 sections and a final skills assessment. Pediatric Advanced Life Support (PALS) also provides some neonatal resuscitation training. On-the-job training is another route. Helping Babies Breathe (HBB), developed by the AAP and partners, targets birth attendants in resource-limited settings, focusing on initial assessment, stimulation, and bag-mask ventilation within the first minute after birth.

Resuscitation guidelines

The International Liaison Committee on Resuscitation (ILCOR) publishes consensus recommendations for neonatal resuscitation. In 2020, its 4th recommendations reviewed 8 major topics including anticipation, initial assessment, ventilation, circulatory support, and post-resuscitation care. Initial evaluation uses the Apgar score: 7–10 at 5 minutes is normal, 4–6 intermediate, and 0–3 low; a score of 0–3 prompts resuscitation. Guidelines resemble pediatric life support but emphasize positive pressure ventilation (PPV) and updated ventilation rates. The 2020 ILCOR changes include ceasing oropharyngeal and nasopharyngeal suctioning for newborns with clear or meconium-stained amniotic fluid, avoiding sustained inflations longer than 5 seconds during PPV, administering intravenous epinephrine if heart rate remains below 60 beats per minute after optimized ventilation and chest compressions, and using umbilical venous catheterization as the primary vascular access route during delivery. Guidelines are assessed annually and developed with multiple organizations including the American Academy of Pediatrics.

Outcomes

Most neonatal deaths after resuscitation (roughly 75%) occur within the first week, with the vast majority within 24 hours, based on a mean Apgar score of 5.9. Outcomes vary widely; one Norwegian analysis of 15 studies found mortality up to 10% in high-income countries and up to 28% in low-income countries, with speed of intervention being a critical factor. High oxygen concentrations generate free radicals linked to reperfusion injury after asphyxia, and clinical trial evidence suggests resuscitation with air probably reduces death risk; the 2010 ILCOR guidelines recommend normal air over 100% oxygen. For preterm infants, higher versus lower oxygen concentrations show little difference in death or neurodevelopmental disability, though evidence remains uncertain. Gold-standard care includes placing neonates on a cooling blanket for 72 hours to minimize brain swelling, followed by an MRI about one week after hypoxic injury to classify brain damage severity, though one study found no significant correlation between MRI findings and developmental delay up to 2 years.
