Abstract
Systematic laryngotracheoscopy, carried out in 50 premature or on-term infants after prolonged intubation gave the following results: 13 cases presented no laryngeal impairment, 1 case bore acute lesions, 13 showed discreet late sequelae, 21 more marked sequelae without respiratory difficulty, and 2 presented severe subglottic obstruction. We were able to establish a significative correlation between the severity of the lesion, the weight of the newborn, and the diameter of the tube put into place. In fact, the late laryngeal sequelae were in general more pronounced in children of feeble birth weight. This is explained by the fact that the smaller the newborn, the relatively bigger is the diameter of the tube, because no intubation material below 2.5 mm in diameter is available commercially.
