Meconium-Stained Nonvigorous Newborn at a Health Center
A 39-week infant is born at a health center after an uncomplicated second stage. The amniotic fluid is thickly meconium-stained. At 30 seconds after birth, the baby is limp, not crying, and has no respiratory effort; the heart rate is 70 beats/min. The health center has a radiant warmer, dry towels, a 250-mL self-inflating bag with masks, suction, and oxygen, but no intubation equipment, no CPAP, and no neonatal intensive care unit. The nearest hospital is 35 minutes away. The midwife is alone with a nursing aide. The mother is stable but anxious and asks why the baby is not crying.
1. Describe your actions in the first 60 seconds. Include what you would do about the meconium and what you would not do.

First 60 seconds: place the baby on the radiant warmer, dry thoroughly with warm towels, discard the wet towels, position the head in a sniffing position, clear the mouth and nose only if secretions are obstructing breathing, and stimulate by rubbing the back or soles. Assess breathing and heart rate.
Meconium: do not routinely intubate and suction the trachea for a nonvigorous meconium-stained newborn. Suction the mouth and nose only if visible meconium is blocking the airway. Do not slap, dunk in cold water, or delay ventilation to suction.
Ventilation: because the baby is apneic with a heart rate of 70, start positive-pressure ventilation with a self-inflating bag at 40–60 breaths/min, using room air initially. Watch for chest rise. If there is no chest rise, reposition the head, check the mask seal, suction the mouth and nose, and consider a pneumothorax. Reassess the heart rate after 60 seconds of effective ventilation.
Reasoning: the priority is effective ventilation, not tracheal suction. The heart rate and chest rise determine whether ventilation is working.
2. After 60 seconds of effective ventilation, the heart rate is still 60 beats/min. What is your next intervention, and how would you give epinephrine if the heart rate remains below 60 after another minute?

Next intervention: start chest compressions because the heart rate is below 60 despite effective ventilation. Use the two-thumb technique, compress one-third of the chest depth, and coordinate three compressions with one breath: 90 compressions and 30 breaths per minute. Increase oxygen to 100%.
Reassessment: check the heart rate every 60 seconds and minimize interruptions. If the heart rate is still below 60 after 60 seconds of compressions with effective ventilation, give epinephrine 0.01–0.03 mg/kg IV via an umbilical venous catheter or intraosseous needle. If no vascular access is available, give 0.05–0.1 mg/kg via the endotracheal tube, although absorption is unreliable.
Reasoning: compressions are indicated only after ventilation is effective, because most newborn bradycardia is caused by hypoxia. Epinephrine is reserved for persistent bradycardia despite good ventilation and compressions. Continue compressions until the heart rate is above 60.
3. The baby responds, with a heart rate of 130 and spontaneous breathing. What post-resuscitation care and transfer decisions are needed?
Read the worked answer
Post-resuscitation care: keep the baby warm but avoid overheating; monitor respiratory rate, heart rate, oxygen saturation, perfusion, and glucose. Give vitamin K and eye prophylaxis when stable. Support breastfeeding or give expressed milk if the mother is stable. Watch for grunting, retractions, apnea, seizures, or poor feeding, which suggest meconium aspiration syndrome, hypoglycemia, or hypoxic-ischemic injury.
Transfer: refer to the hospital for observation even if the baby looks well, because complications can appear hours later and the health center has no neonatal intensive care. Stabilize before transport: keep warm, secure the airway and breathing, check glucose, and document the resuscitation times, interventions, and response.
Reasoning: a good response to resuscitation does not rule out aspiration or brain injury. The midwife's responsibility continues through safe transport and clear handover.
