Anesthetic management of retinoblastoma patients is unremarkable in most
cases. Patients are most often babies and laryngoscopic procedures for
intubation are usually easy. However, we recently experienced two cases
with retinoblastoma with whom tracheal intubation was accomplished with
difficulty. We report the two cases with a review of all 5-year records of
retinoblastoma (rbl) in our institution. The cases we experienced recently
were all patients with rbl with deletion of the long arm of thirteenth
chromosome (13q-). In the 5-year review, the incidence of the difficult
intubation was significantly higher (P < 0.05) in rbl with 13q- (4/11)
than in rbl without 13q- (0/147). In our experience macroglossia was noted
for the difficulty in the intubation. We assume that some patients with rbl
will be cases of difficult intubation even to cannot ventilate-cannot
intubate level when the results of their chromosomal analysis show a
deletion on the thirteenth chromosome.
