Difficult airway in a syndromic child: Pierre Robin, Treacher Collins, cleft palate
Stem
An 11-month-old girl, 8 kg, with Pierre Robin sequence and Stickler syndrome is scheduled for cleft palate repair. As a neonate she needed prone positioning and a nasopharyngeal airway; she still snores and obstructs when supine and asleep. She has never had an anesthetic. Her mandible is small and receding, and the cleft is wide.
Question
How will you secure her airway?
Ideal answer
HeadlineI expect difficult mask ventilation and laryngoscopy, so I keep her breathing spontaneously until I know I can ventilate, with an SGA ready as rescue and conduit.
- Second anesthesiologist, ENT and difficult-airway cart present, because both ventilation and laryngoscopy may fail: nasal and oral airways, SGAs, video laryngoscope, flexible bronchoscope, tracheostomy kit.1,2
- Inhalational induction, spontaneous ventilation, then an IV, because maintaining spontaneous ventilation is critical; jaw thrust or a nasal airway lifts the tongue off the pharynx.1
- Video laryngoscope, or fiberoptic through an SGA, because direct laryngoscopy rarely succeeds first time in these children; I limit attempts.3,4
- SGA for rescue oxygenation if intubation fails, then decide to wake her or proceed.4
- Extubate fully awake, minimal opioid, monitored bed, because postoperative obstruction is the main risk.1
Breaking down the answer
- Multilevel obstruction — glossoptosis at the oropharynx, base-of-tongue and epiglottic collapse lower down, sometimes laryngomalacia or subglottic disease;1 that is why I review the bedside nasolaryngoscopy and ask what position relieves her.
- Age changes the answer — nonsyndromic Pierre Robin often improves with mandibular catch-up growth; Treacher Collins gets harder with age as the face grows dysmorphic.2 Changes if: a prior anesthetic record, which is the best predictor I have.
- PeDI numbers — in 1018 difficult pediatric intubations, first-attempt success was 3% by direct laryngoscopy, 54% fiberoptic and 55% video; complications followed more than two attempts and weight under 10 kg.3
- When to give a relaxant — ESAIC/BJA advise neuromuscular block when spontaneous breathing is not necessary;4 once I can mask-ventilate easily, paralysis improves conditions. Changes if: ventilation is marginal, then she keeps breathing.
- Associated syndromes — over half have an associated syndrome or anomaly, most often Stickler or 22q11 deletion;1 a murmur gets an echocardiogram before elective surgery.
- Intraoperative trap — the surgeon's mouth gag can kink or displace an oral RAE tube; I watch peak pressure and capnography each time it opens.
Follow-up question
She is extubated awake. Twenty minutes later in recovery she has stertor, retractions and a saturation of 84% on face-mask oxygen, and she is drowsy after morphine. What do you do?
Follow-up answer
HeadlineUpper-airway obstruction after palate repair, worsened by opioid; I call for help and the airway cart and tell the surgeon.
Jaw thrust and lateral or prone positioning, CPAP with 100% oxygen, and a nasal airway or traction on the tongue stitch after agreeing with the surgeon, since the palate repair is fresh. I titrate naloxone if opioid is contributing. If she does not improve quickly, I reintubate with the same technique that worked, through an SGA if needed, and send her to intensive care. In a two-center cohort, 15% had adverse events, 40% of them in recovery.5
Pitfalls that cost points
- Planning an adult-style awake fiberoptic: an infant cannot cooperate, so "awake" means spontaneously breathing under inhalational anesthesia.
- Forgetting eye protection in Treacher Collins, where lid colobomas leave the cornea exposed during a long intubation.2
- Assuming the airway is easy because the cleft palate is now closed; repair reduces airway space.
Rapid-fire
Q: What is the Pierre Robin triad? A: Micrognathia, glossoptosis and airway obstruction; cleft palate is present in up to 90% but is not required.1
Q: How often does Treacher Collins include a cleft palate? A: About 40%; obstructive sleep apnea from multilevel obstruction is common.2
Q: Commonest adverse events after palatoplasty? A: Hypoxemia 9.2% and upper-airway obstruction 6.3%; nasal stent placement and prolonged emergence predicted events.5
Q: Surgical options for neonatal obstruction? A: Tongue-lip adhesion, mandibular distraction osteogenesis, which often keeps the child intubated for days, or tracheostomy for severe multilevel disease.1
Q: What confirms the tube in an infant? A: Clinical assessment plus an end-tidal CO2 waveform.4
