[Difficult Airway Management in a Low Birth Weight Infant Using an Upper Gastrointestinal Endoscope]
Insights
An upper gastrointestinal endoscope successfully enabled tracheal intubation in a low birth weight infant with a difficult airway. This approach provided clear visualization, overcoming challenges from congenital anomalies and secretions.
Area of Science:
- Pediatric Anesthesiology
- Neonatal Intensive Care
- Medical Device Technology
Background:
- Difficult airway management in neonates presents significant challenges.
- Congenital anomalies like Goldenhar syndrome can complicate airway visualization.
- Standard intubation techniques may be insufficient in complex neonatal cases.
Observation:
- A 1.8 kg neonate with micrognathia and facial clefts required surgical repair.
- Direct laryngoscopy and the Pentax Airway Scope failed to visualize the larynx.
- Copious secretions and a narrow oral cavity further impeded intubation attempts.
Findings:
- An upper gastrointestinal endoscope, with insufflation and suction, provided excellent visualization of the vocal cords.
- Successful nasotracheal intubation was achieved using the gastrointestinal endoscope.
- This device proved effective in a case of Cormack-Lehane grade 4 difficulty.
Implications:
- Upper gastrointestinal endoscopy is a viable rescue technique for neonatal difficult airway intubation.
- This method offers a valuable alternative when conventional tools fail.
- Enhanced visualization and secretion management are key benefits for neonatal airway procedures.
Abstract:
We report a successful tracheal intubation in a low birth weight infant with difficult airway by using an upper gastrointestinal endoscope. A 1-day-old female weighing 1.8 kg having micrognathia, lateral facial cleft, and bilateral microtia suggestive of Goldenhar syn- drome complicated with total anomalous pulmonary venous connection was scheduled for surgical repair of duodenal atresia. Awake intubation was planned because of anticipated difficult intubation. Direct laryn- goscopy with Miller blade (size 0) after intravenous lidocaine did not visualize the larynx or epiglottis (Cor- mack-Lehane grade 4). After several failed attempts at intubation using BURP procedure, Pentax Airway Scope? equipped with a neonatal-type Intlock* (ITL- N) was tried but a good view of the larynx was not obtained because of the narrow oral cavity and copious secretion. After failed attempts with Airway Scope?, an upper gastrointestinal endoscope was inserted into the oral cavity and equipped insufflation and suctioning of the secretion were utilized, which provided a good view of the vocal cords and enabled nasotracheal intu- bation. An upper gastrointestinal endoscope could provide a good view of the larynx by using insufflation, and suc- tioning, and can be one of the useful devices for tra- cheal intubation of difficult airway.
