Background:
Extubation is a more challenging medical practice than intubation, and countermeasures against it are similar to those described in the Difficult Intubation Guidelines, but problems cannot be overcome by completely the same methods. We predicted difficult extubation in a pediatric patient with left recurrent laryngeal nerve paralysis and devised an extubation method.
Case presentation:
The patient was a 2-year-and-8-month-old boy scheduled for cleft palate repair. Concomitant cardiac anomaly and first and second branchial arch syndrome-associated facial malformations, such as mandibular micrognathia and auricular malformation, were observed. He had a past medical history of difficult intubation and respiratory arrest on a catheter test under intravenous sedation at 4 months old. Left recurrent laryngeal nerve paralysis was discovered on preoperative examination of the cleft palate, based on which difficulty in postoperative extubation was predicted. A catheter for tracheal tube exchange proposed by the extubation guidelines of the Difficult Airway Society (DAS) was placed, endoscopic examination was performed while inducing spontaneous breathing and swallowing reflex by an otolaryngologist, and the tube was removed while movement of the tissue around the glottis was visually evaluated. The patient was managed in an ICU after extubation, and both the systemic and respiratory conditions were favorable.
Conclusions:
Extubation and airway management could be safely performed by devising extubation while conforming to the DAS guidelines.
