Situation: A nurse in the delivery room and newborn nursery of a provincial hospital receives newborns at birth and during the first days of life.

A newborn is born at 39 weeks of gestation through thick meconium-stained amniotic fluid. He is limp and not breathing. The nurse has dried him, positioned his head, and cleared secretions from his mouth and nose, but at 30 seconds of age he is still not breathing. Which action should come NEXT?

1. Intubate and suction the trachea before any breath
2. Give free-flow oxygen held close to his face
3. Start bag-and-mask ventilation with room air **✔ 정답**
4. Rub his back and soles for another 30 seconds

**정답: 3**

## 해설

A newborn who is still not breathing after drying, positioning, and clearing the airway needs ventilation started within the first minute of life. The DOH Essential Intrapartum and Newborn Care protocol, WHO basic newborn resuscitation, and the AHA/AAP guidelines agree on this step: bag-and-mask ventilation, starting with room air for an infant born at 35 weeks or later. Routine tracheal suctioning for meconium is not recommended because it delays ventilation.

Initial Assessment and the First Minute of Life

The newborn in this scenario presents with three critical findings: term gestation at 39 weeks, thick meconium-stained amniotic fluid, and a non-vigorous state characterized by limpness and apnea. After the initial steps of drying, positioning the head to open the airway, and clearing secretions from the mouth and nose, the infant remains apneic at 30 seconds of age. This is the decisive moment in the resuscitation algorithm.

When a newborn remains apneic or has a heart rate below 100 beats per minute after initial drying and airway clearing, positive-pressure ventilation must be initiated within the first minute of life. The priority is not further stimulation or suctioning, but establishing effective ventilation to expand the lungs and initiate gas exchange.

Why Bag-and-Mask Ventilation, Not Tracheal Suctioning

Historically, non-vigorous infants born through meconium-stained amniotic fluid underwent immediate endotracheal intubation and tracheal suctioning before any positive-pressure breaths. This practice was based on the theoretical concern that meconium below the vocal cords could be aspirated into the lungs during resuscitation. However, this approach has been abandoned in current guidelines.

The 2025 Korean Guidelines for Cardiopulmonary Resuscitation and the 2026 Singapore Neonatal Resuscitation Guidelines both reflect the international consensus: routine tracheal suctioning for non-vigorous meconium-stained newborns is no longer recommended because the delay in initiating ventilation causes greater harm—prolonged hypoxia and acidosis—than any theoretical benefit from removing meconium. The most effective way to clear meconium from the lower airway is to establish functional residual capacity and effective ventilation, which moves air past any meconium and allows the infant's own clearance mechanisms to work.

A retrospective cohort study comparing outcomes before and after the 2016 Neonatal Resuscitation Program guideline change found that non-vigorous neonates born through meconium-stained amniotic fluid did not have worse outcomes when routine endotracheal suctioning was omitted [4]. This supports the current approach of prioritizing ventilation.

Room Air as the Initial Gas Source

For a term infant at 39 weeks gestation, the initial gas for bag-and-mask ventilation is room air (21% oxygen). The European Resuscitation Council 2025 guideline and the Korean 2025 guideline both affirm that term and late preterm infants should begin resuscitation with room air, with oxygen supplementation guided by pulse oximetry and clinical response [1]. Starting with 100% oxygen exposes the newborn to unnecessary oxidative stress and is associated with increased mortality in some studies.

Why the Other Options Are Incorrect

| Option | Action | Why It Is Incorrect |
| --- | --- | --- |
| 1 | Intubate and suction the trachea before any breath | Delays ventilation; routine tracheal suctioning is no longer recommended for non-vigorous meconium-stained newborns. Intubation is reserved for infants who do not respond to bag-and-mask ventilation or require prolonged ventilatory support. |
| 2 | Give free-flow oxygen held close to his face | Free-flow oxygen does not provide positive pressure and cannot ventilate an apneic infant. It is appropriate for a breathing infant with cyanosis, not for apnea. |
| 4 | Rub his back and soles for another 30 seconds | Additional tactile stimulation is inappropriate once the infant has been dried and stimulated. Prolonged stimulation delays the critical intervention of positive-pressure ventilation. The infant is already at 30 seconds of age; ventilation must begin now. |

Clinical Application and Priority Sequence

The correct sequence in neonatal resuscitation follows a strict time-based algorithm. The initial steps—drying, positioning, clearing the airway, and stimulating—should take no more than 30 seconds. If the infant remains apneic or gasping, or if the heart rate is below 100 beats per minute, positive-pressure ventilation is initiated immediately. Key point! The most common reason a newborn fails to respond to initial steps is ineffective ventilation, not airway obstruction from meconium. Watch out! Do not confuse the historical practice of routine tracheal suctioning with current evidence-based guidelines. The 2025 and 2026 international guidelines consistently recommend initiating bag-and-mask ventilation with room air as the next step for an apneic term newborn, regardless of meconium staining [1][3].

The nurse should apply a properly sized mask to create a seal over the infant's mouth and nose, then deliver positive-pressure breaths at a rate of 40 to 60 breaths per minute, observing for chest rise and improvement in heart rate. Ventilation effectiveness is assessed by rising heart rate, not by the presence of breath sounds alone. If the heart rate does not improve within 30 seconds of effective ventilation, the resuscitation team should reassess mask seal, airway position, and consider advanced airway management.References (research sources)

## 임상 시나리오

Neonatal Resuscitation in Meconium-Stained Amniotic FluidPrioritize ventilation over suctioning in non-vigorous newborns
If a newborn remains apneic after drying, positioning, and airway clearing, initiate bag-and-mask ventilation within the first minute of life. For infants born at 35 weeks or later, start with room air.

Routine tracheal suctioning for meconium is not recommended, even in non-vigorous newborns, because it delays ventilation and does not improve outcomes.

CautionDo not continue stimulation beyond 30 seconds of apnea. Effective positive-pressure ventilation is the priority, not further suctioning or tactile stimulation.

## 핵심 개념

- **Positive-pressure ventilation** — Delivery of breaths via bag-and-mask to expand the lungs and initiate gas exchange in an apneic or bradycardic newborn.
- **Non-vigorous newborn** — A newborn with poor muscle tone, apnea, or heart rate below 100 bpm, requiring immediate resuscitation.
- **Meconium-stained amniotic fluid** — Amniotic fluid containing fetal stool, which may be associated with fetal distress but no longer mandates routine tracheal suctioning.
- **Room air resuscitation** — Initial gas source for bag-mask ventilation in term or late preterm newborns, per current neonatal resuscitation guidelines.
- **First minute of life** — The critical window after birth during which effective ventilation must be established for apneic newborns.
