Effective Resuscitation Techniques for Newborns

Every minute counts when a newborn struggles to take their first breath. While most babies transition smoothly from the womb to the outside world, approximately 5% to 10% of newborn infants need help to begin breathing at birth, and about 1% require advanced resuscitative measures. Understanding neonatal resuscitation techniques isn’t just a clinical skill-it’s a life-saving competency that every healthcare professional working with newborns must master.

Why newborn resuscitation is unique 🔗

Neonatal resuscitation differs fundamentally from adult or even paediatric resuscitation because of the unique physiological transition from fetal to neonatal life. Before birth, the baby’s lungs are filled with fluid, and oxygen comes from the placenta. Within seconds of delivery, the newborn must clear this fluid, inflate their lungs with air, and establish independent breathing. When this transition fails, immediate intervention becomes critical.

Unlike older patients where cardiac problems often cause the need for resuscitation, in newborns, bradycardia is usually the result of inadequate lung inflation or profound hypoxemia. This is why ventilation-not chest compressions-is the cornerstone of neonatal resuscitation.

The initial steps: TABC approach 🔗

The mnemonic TABC stands for Temperature, Airway, Breathing, and Circulation-representing the systematic approach to newborn stabilisation.

Temperature control 🔗

Hypothermia compromises resuscitation significantly. Hypothermia at the time of admission increases the risk of morbidity and mortality in neonates, particularly preterm infants. Immediately after birth, the baby should be dried thoroughly, wet linens removed, and the infant placed under a radiant warmer. The ideal temperature targets range between 36.5°C and 37.5°C. For very preterm babies under 32 weeks’ gestation, wrapping them in plastic without drying helps maintain adequate body temperature.

Airway positioning 🔗

Proper positioning is essential for maintaining an open airway. The neonate should be laid on their back with the head in a neutral position-often called the “sniffing” position. Avoid flexing or hyperextending the neck, as this can obstruct the airway. The initial steps include clearing secretions only when necessary, particularly if copious secretions are present or if the airway appears obstructed.

Stimulation to breathe 🔗

Tactile stimulation can trigger spontaneous breathing. Rubbing the back and soles of the feet vigorously but not roughly can encourage respiratory effort. However, harmful practices like shaking, slapping, or hanging the infant by the feet should never be used. If the baby doesn’t respond within 5 seconds, move to ventilation immediately.

Assessment and monitoring 🔗

Continuous evaluation guides all resuscitation decisions. Heart rate is the most important vital sign in determining the effectiveness of resuscitative interventions. Healthcare providers should assess:

Heart rate: Auscultation with a stethoscope over the chest is the initial method. A heart rate below 100 beats per minute indicates the need for intervention, while below 60 beats per minute despite ventilation signals the need for chest compressions.

Respiratory effort: Look for crying, gasping, or absence of breathing. Gasping is not effective breathing and requires immediate intervention.

Oxygen saturation: Pulse oximetry should be applied to the right wrist or hand to obtain pre-ductal oxygen saturation, which represents cerebral blood flow oxygenation. Newborns normally have oxygen saturation around 60% at 1 minute of life, gradually increasing to 85% by 5 minutes.

Positive pressure ventilation: the critical intervention 🔗

Ventilation remains the primary method for providing support for newborn infants who are apneic, bradycardic, or demonstrate inadequate respiratory effort. Most newborns will respond to this single intervention.

Equipment for ventilation 🔗

Three main devices can deliver positive pressure ventilation:

Self-inflating bag: This device fills automatically and doesn’t require a gas source to function. It’s widely available and easy to use. However, delivering consistent positive end-expiratory pressure (PEEP) requires an additional valve attachment.

Flow-inflating bag: Requires a compressed gas source but provides better control over pressure delivery. It allows practitioners to feel lung compliance during ventilation.

T-piece resuscitator: T-piece resuscitators deliver controlled, consistent, and precise pressures independent of operator experience. International resuscitation guidelines recommend using a T-piece resuscitator when a gas source is available.

Mask selection and technique 🔗

International guidelines recommend that an appropriately sized infant face mask should cover the mouth and nose but not the eyes, and should not overlap the chin. Achieving a good seal with minimised leak is essential for effective ventilation. The masks are available in different sizes-typically size 0 for preterm babies and size 1 for term infants.

Ventilation should occur at a rate of 40-60 breaths per minute. Signs of effective ventilation include visible chest rise and an increasing heart rate. If the chest doesn’t rise, reposition the head, ensure a proper mask seal, clear the airway, or increase inflation pressure.

Oxygen considerations 🔗

Use of lower inspired oxygen concentration during neonatal resuscitation decreases short-term mortality in term newborns. Current recommendations suggest starting with room air (21% oxygen) for term infants and 21-30% for preterm infants. If the heart rate doesn’t improve with effective ventilation, increase the oxygen concentration. Once chest compressions become necessary, oxygen should be increased to 100%.

External cardiac massage: when ventilation isn’t enough 🔗

If a newborn has severe bradycardia with heart rate below 60 beats per minute despite effective ventilation for 30 seconds, chest compressions are indicated. Before starting compressions, ensure an advanced airway (endotracheal tube or supraglottic airway) is in place.

Two-thumb technique 🔗

The two thumb-encircling hands technique is preferable because it results in better peak systolic and coronary perfusion pressure. The rescuer encircles the infant’s chest with both hands, placing both thumbs over the lower third of the sternum, just above the xiphoid process.

Compression depth: Compress to approximately one-third of the chest’s anterior-posterior diameter-deep enough to generate a palpable pulse.

Compression-to-ventilation ratio: The ratio is 3:1, delivering 90 compressions and 30 breaths per minute-totalling 120 events per minute.

Coordination: Simultaneous ventilation and chest compressions are not recommended. Instead, pause briefly after every three compressions to deliver one breath. The person performing compressions should count aloud to maintain coordination.

Essential resuscitation equipment 🔗

Neonatal resuscitation requires specific equipment that must be checked and readily available before every delivery:

Suction equipment: Bulb syringe, mechanical suction with catheters (size 5, 8, and 10 French), and meconium aspirator for cases with meconium-stained amniotic fluid.

Ventilation equipment: Self-inflating neonatal resuscitation bag with masks for pre-term (size 0) and term (size 1) babies, oxygen source with flowmeter, and blender for oxygen concentration adjustment.

Intubation supplies: Laryngoscope with straight blades (sizes 00, 0, and 1), endotracheal tubes in various sizes (2.5mm for infants under 1kg, 3mm for 1-2.5kg, and 3.5mm for larger babies), and a stylet.

Medications: Epinephrine (adrenaline) at 1:10,000 concentration, volume expanders like normal saline, and supplies for umbilical venous catheter placement.

Medications in neonatal resuscitation 🔗

Drugs are rarely indicated in resuscitation of the newly born infant. When the heart rate remains below 60 beats per minute despite effective ventilation and chest compressions, epinephrine (adrenaline) becomes necessary.

Epinephrine administration: The intravenous or intraosseous dose is 10-30 micrograms per kilogram. If vascular access isn’t available, epinephrine can be given through the endotracheal tube at a higher dose of 50-100 micrograms per kilogram. The intravenous route is most effective.

Volume expansion: For newborns with suspected blood loss who aren’t responding to resuscitation, isotonic crystalloid or O-negative blood may be given in 10ml/kg boluses through an umbilical venous catheter.

When to consider stopping resuscitation 🔗

If all steps of resuscitation are effectively completed and there is no heart rate detected by 20 minutes, redirection of care may be discussed with the team and family. This difficult decision requires clear communication and compassion, allowing parents time to see and hold their baby when appropriate.

The importance of preparation and teamwork 🔗

Regular practice through interdisciplinary simulation helps teams work well together, enabling resuscitation team members to be comfortable performing all roles efficiently. Risk factors like preterm birth, fetal distress, meconium-stained amniotic fluid, or emergency caesarean section should alert the team to prepare for potential resuscitation needs.

Clear role assignment, equipment checks, and briefing about maternal and fetal risk factors should occur before every high-risk delivery. A well-prepared team with strong communication skills performs resuscitation far more effectively than individuals working in isolation.
