[Endotracheal intubation for a neonatal patient complicated with Arnold-Chiari malformation using a Pentax airway scope with a neonatal-type INTLOCK blade (ITL-N)].

: Several previous reports have established the Pentax Airway Scope (Pentax AWS, S-100, HOYA-PENTAX, Tokyo, Japan) as an efficient tool for endotracheal intubation in adult patients. To date, however, there are no reports on its use with the INTLOCK blade for neonatal and pediatric patients. In this case, we performed tracheal intubation using a Pentax AWS attached to a neonatal-type INTLOCK blade (ITL-N) twice, 1 day and 10 days after birth, in a neonatal patient complicated with Arnold-Chiari malformation. The patient weighed 2.2 kg and was 47 cm tall. The first operation consisted of the repair of a meningocele ; the second was for the insertion of an indwelling Ommaya reservoir. We initially attempted tracheal intubation using a Miller's laryngoscope in the first operation and a Macintosh laryngoscope in the second, but we could not achieve tracheal intubation with either of these instruments. Upon switching to a Pentax AWS with an ITL-N, however, we successfully achieved tracheal intubation in both operations. Further research is needed to facilitate the effective use of the Pentax AWS in such cases.
