Intubation in Pierre Robin syndrome


Pierre Robin Sequence (PRS) is a collection of physical characteristics of a newborn that includes micrognathia (small jaw), glossoptosis (tongue falls to back of throat), and airway obstruction . The incidence of PRS varies from 1:5000-1:85,000. Although most patients with PRS have a cleft palate, it is not a requirement for the diagnosis. Pierre Robin is thought to be secondary to a fixed fetal position in utero that inhibits appropriate mandibular growth. Pierre Robin infants often present with feeding dysfunction, failure to thrive, and respiratory distress. PRS may present as an isolated sequence or may be associated with a syndrome. The most common syndromes are Stickler, velocardiofacial (22q,11.2 deletion), fetal alcohol syndrome, and Treacher-Collins Syndrome. If mild airway obstruction is present, airway function can be improved with prone positioning and placement of nasopharyngeal airway with resultant forward placement or mechanical bypass of the tongue. Approximately 25-50% of PRS patients will require surgical intervention, including tongue-lip adhesion, mandibular distraction osteogenesis (MDO), or tracheostomy for airway management as well as gastrostomy tube placement for feeding management.

Airway management in an uncorrected PRS patient can be a potentially difficult undertaking that should be performed in a center that is comfortable with difficult pediatric airways. Nasal intubation is preferred for both tongue-lip adhesion and MDO. While the most conservative approach to securing the airway is an awake fiberoptic intubation, numerous publications discuss successful mask induction with asleep intubation. Marston, et al. described successful ventilation after mask induction in 100% of their 33 patients with the aid of naso- or oro-phargyneal airway. Direct laryngoscopy (DL) was successful within two attempts in 37% of the infants; subsequent flexible fiberoptic bronchoscopy was successful in the remainder of the patients. Several airway techniques have been described to assist in the difficult airway for the patient with PRS. These techniques include LMA, fiberoptic scope, shikani scope, Airtraq, and Air-Q scope. An LMA can also be placed in an awake or an asleep infant with PRS to ventilate and then to guide a fiberoptic intubation. Alternative intubation methods with a videolaryngoscope (Glidescope) may also be useful.
