“…In a patient with wide glottic opening, controlled ventilation through a relatively small size endotracheal tube should be preferred and in a child with narrow glottic chink, DLCVC may be chosen. Two third of the patients (24 of 36) in the study had grade I obstruction only and probably not very narrow glottis chink. Hence, successful use of this device in large number of children with narrow glottic chink needs further evaluation.…”
