It can be seen with a normal trace in a healthy term baby, but with an abnormal trace it signals possible hypoxia. The main neonatal danger is meconium aspiration syndrome, so care relies on continuous monitoring, a neonatal team at birth and careful airway handling. ## What you must remember - **Grading:** thin or thick meconium. Thin meconium is more common, while thick meconium is the stronger warning sign for aspiration. - **Significance:** passage of meconium in a cephalic term fetus with a normal CTG is often benign, whereas meconium with an abnormal trace needs urgent assessment. - **Meconium aspiration syndrome:** respiratory distress from inhaled meconium, which may occur after in utero gasping in a hypoxic fetus. - **Monitoring:** continuous electronic fetal monitoring is preferred once meconium is seen, so that changes in the trace can be acted on. - **At birth:** a neonatal team should attend, and a non-vigorous baby receives standard resuscitation steps with positive pressure ventilation if apnoeic or heart rate is under 100 per minute. - **Routine suction:** routine tracheal intubation and suction is no longer recommended, in vigorous or non-vigorous babies; it is reserved for a suspected airway obstruction (NRP since 2015). - **Amnioinfusion:** not used routinely, and considered only in selected cases under local protocol. ## A response plan from liquor to newborn airway When meconium is seen, the decision rests on the trace and on the newborn's condition at birth. The steps below put the team in a clear order, from the first sight of meconium to the handover to neonatal care. 1. **Note the colour and thickness.** Record whether the liquor is light, thin or thick meconium at membrane rupture and at each later examination. 2. **Assess the fetal trace.** A reassuring trace in a cephalic term baby allows labour to continue with close monitoring. 3. **Escalate on an abnormal trace.** Category II or III findings prompt the usual steps for fetal compromise, including reassessment, maternal repositioning and consideration of delivery. 4. **Alert the neonatal team.** For thick meconium, paediatric support should be present at the birth. 5. **Plan the airway at birth.** Assess tone, breathing and heart rate, and keep the baby warm. Start ventilation promptly if the baby is not breathing or the heart rate is low, and suction the trachea only if the airway looks obstructed. 6. **Admit and observe the baby.** A baby with significant aspiration, respiratory distress or a low Apgar score is transferred to neonatal care for ventilatory support as needed. ## Where the exam tries to catch you Meconium questions test whether the candidate reads the trace before reacting to the colour of the liquor, and whether the neonatal airway is handled correctly. - **Trap:** assuming all meconium means fetal distress — **Correct:** meconium with a normal trace in a cephalic term fetus may be benign, and the CTG decides the response. - **Trap:** suctioning the trachea of every baby born through meconium — **Correct:** routine tracheal suction is not recommended, even in a non-vigorous baby, who is resuscitated by standard NRP steps; tracheal suction is for suspected airway obstruction. - **Trap:** confusing meconium aspiration syndrome with transient tachypnoea — **Correct:** meconium aspiration is a syndrome from inhaled meconium that can need ventilatory support, so it is not managed by observation alone. ## Frequently asked questions ### Is meconium-stained liquor always a sign of fetal distress? Meconium-stained liquor is not always a sign of fetal distress, because it can be seen with a normal trace in a term cephalic baby. The fetal heart trace decides the response. Meconium with an abnormal trace indicates possible hypoxia and needs urgent assessment. ### What is meconium aspiration syndrome? Meconium aspiration syndrome is respiratory distress in a newborn caused by inhaled meconium, often after in utero gasping in a hypoxic fetus. It can cause airway obstruction, chemical pneumonitis and pulmonary hypertension. Management needs neonatal support, and ventilation may be required. ### Should the trachea be suctioned routinely at birth in meconium-stained liquor? Routine tracheal suction of a newborn born through meconium is not recommended, whether the baby is vigorous or not. A non-vigorous baby gets standard resuscitation, with ventilation if apnoeic or the heart rate is low, and tracheal suction only for suspected obstruction. Older textbooks still describe routine intubation. ### Is amnioinfusion used for meconium-stained liquor? Amnioinfusion is not used routinely for meconium-stained liquor. It may be considered in selected cases, such as thick meconium with a concerning trace, according to local protocol. The evidence is limited, so it is used with caution. ### Which babies born through meconium need neonatal care? Babies born through meconium who are non-vigorous, have respiratory distress or have a low Apgar score need neonatal care. A paediatric team should attend the birth of a baby with thick meconium. Close observation follows for signs of aspiration.
