Pediatric Gasping Patient: Non-Intubation Medical Management

1. Immediate Basic Airway Maneuvers

• Repositioning: Sniffing position (infants) or head-tilt/chin-lift to maximize airway patency. Children's larger occiput means neutral or slight sniffing posture is often ideal, not hyperextension.
• Jaw thrust if cervical spine injury is suspected.
• Oral/nasal airways (OPA/NPA): Stent open the upper airway in partial obstruction or depressed consciousness. Particularly useful in tonsillar/adenoidal obstruction.
• Suctioning: Clear secretions, blood, vomit promptly.
• Calm environment: In upper airway pathology (e.g. croup, epiglottitis), agitation worsens obstruction — keep child with parent, minimise distress.

"Signs of partial obstruction (sonorous or stridulous airway noises)... should prompt immediate basic airway maneuvers, including airway repositioning or insertion of oral and nasal airways to help stent open the upper airways." — Rosen's Emergency Medicine

2. Bag-Mask Ventilation (BMV)

• First-line rescue ventilation when child cannot maintain adequate breathing.
• Children with complete upper airway obstruction often respond well to positive-pressure BMV, which mechanically stents open a collapsible trachea.
• 2-person technique (one holds mask seal, one squeezes bag) improves efficacy.
• Caution: Children are prone to gastric insufflation (large stomach, low oesophageal tone) → consider OG/NG tube decompression if abdomen distends and impedes diaphragmatic excursion.
• Avoid cricoid pressure routinely — if used and chest rise is poor, release it.

3. Supplemental Oxygen & Preoxygenation

• High-flow oxygen via non-rebreather mask immediately.
• Nasal cannula 1–2 L/min/year of age (max 15 L/min) during any apnoeic interval maintains passive oxygenation (apnoeic oxygenation).
• Children desaturate rapidly — a sick infant may drop below SpO₂ 90% in <1 minute of apnoea. Meticulous preoxygenation is critical before any procedure.

4. High-Flow Nasal Cannula (HFNC)

• Delivers warmed, humidified oxygen at high flows; provides low-level CPAP effect, washes out nasopharyngeal dead space, reduces work of breathing.
• Evidence in bronchiolitis and respiratory distress in children — widely used as a step-up from standard O₂ before intubation.
• Literature supports use in paediatric respiratory distress (Mikalsen et al., referenced in Rosen's).

5. CPAP / BiPAP (Non-Invasive Positive Pressure Ventilation — NIPPV)

• CPAP: Rapidly pressurises and splints open the upper airway; reduces stridor and dyspnoea in upper airway obstruction; effective in bronchiolitis, acute asthma, pulmonary oedema.

  "CPAP can quickly pressurize and, in effect, splint open the upper airway to reduce stridor and dyspnea." — Murray & Nadel's Respiratory Medicine

• BiPAP: Adds inspiratory pressure support — useful when both oxygenation and ventilation are failing (e.g. status asthmaticus, neuromuscular disease).
• Paediatric masks/interfaces are available; cooperation can be a limiting factor in young children.

6. Heliox (Helium-Oxygen Mixture)

• Typically 70% helium / 30% oxygen blend.
• Helium's low density (~1/7 that of nitrogen) converts turbulent to laminar flow, dramatically reducing airway resistance in partially obstructed airways.
• Useful in: croup, subglottic stenosis, severe asthma, post-extubation stridor.
• Effect is lost below ~60% helium concentration (limits use when FiO₂ >40% is needed).
• Cochrane evidence: no more effective than racemic epinephrine or humidified O₂ for croup in reducing distress severity, but a reasonable bridge.

  "Heliox, typically a 70% to 30% mixture of helium to oxygen, can help decrease a child's work of breathing by increasing laminar flow in partially obstructed airways." — Rosen's Emergency Medicine

7. Cause-Specific Pharmacotherapy

8. Supraglottic Airways (SGAs) as Bridge

• Laryngeal mask airway (LMA) — can be placed without paralysis or direct laryngoscopy.
• Appropriate sizes available for all paediatric ages.
• Provides oxygenation/ventilation when BMV is inadequate and intubation not yet achievable.
• Not a definitive airway but a vital bridge.

9. Needle Cricothyrotomy (Last Resort)

• If BMV, SGAs, and intubation all fail (can't intubate, can't oxygenate), needle cricothyrotomy is the recommended invasive rescue in children rather than surgical cricothyrotomy (membrane too small).
• Provides temporary oxygenation only (jet insufflation) until definitive airway secured.
