A term newborn (38 weeks gestation) is delivered vaginally after an uncomplicated pregnancy. At 1 minute of life, the infant has a heart rate of 95 bpm, is cyanotic centrally, has weak cry, some flexion of limbs, and grimaces to suctioning. What is the most appropriate next step in management?

Question

Accepted Answer

C. Initiate positive pressure ventilation with 21% oxygen and reassess at 15 seconds. ## Clinical Assessment The 1-minute APGAR score in this scenario is: - Heart rate 95 bpm = 1 point - Central cyanosis = 1 point - Weak cry = 1 point - Some flexion = 1 point - Grimace response = 1 point **Total APGAR = 5 (moderately depressed)** ## Neonatal Resuscitation Algorithm ```mermaid flowchart TD A["Newborn delivered"]:::outcome --> B{"Term gestation?

Dry, warm, suction"]:::action B -->|"No to any"| D{"Apneic or

Improving?"}:::decision G --> I I -->|"Yes"| J["Continue PPV, wean O₂"]:::action I -->|"No"| K["Increase O₂ to 40%
Check technique"]:::action ``` ## Key Point: **APGAR 4–6 = Moderately depressed → Initiate PPV with 21% oxygen (room air).** This infant meets criteria for PPV: - Central cyanosis despite being term - Weak cry (inadequate respiratory effort) - Bradycardia (95 bpm is borderline low for a newborn at 1 min) ## High-Yield: **Oxygen titration in neonatal resuscitation:** - Start with 21% O₂ (room air) for term infants - If no improvement in 15 seconds and HR remains < 100, increase to 40% - Reserve 100% O₂ for persistent bradycardia or non-responsive cases - Avoid hyperoxia in preterm infants (risk of retinopathy of prematurity, bronchopulmonary dysplasia) ## Clinical Pearl: **The 15-second reassessment rule:** After initiating PPV, reassess HR, respiratory effort, and color at 15 seconds. If HR ≥ 100 and improving, continue PPV and gradually reduce FiO₂. If no improvement, escalate oxygen concentration and check technique. ## Mnemonic: **APGAR scoring: Appearance, Pulse, Grimace, Activity, Respiration** - 0–3 = Severely depressed (immediate resuscitation) - 4–6 = Moderately depressed (PPV with 21% O₂) - 7–10 = Normal (routine care) [cite:NRP 8th Edition]
