ABSTRACT

Objective: To study the clinical, radiographic, and endoscopic features of persistent atelectasis in pediatric patients on the basis of the radiological course 24 hours after bronchoscopic selective aspiration.
Design: Retrospective, longitudinal, descriptive, and observational.
Location and date: Pediatric Pulmonology and Chest Surgery Department at the Instituto Nacional de Pediatría in Mexico City, between January 1990 and January 1993.
Material and Methods: The clinical and radiographic files of patients with persistent atelectasis were selected. The following information was recorded: age, sex; and a history of the following: prematurity; hyaline membrane disease; previous neck, abdomen or chest surgery. Duration both of mechanical ventilation and atelectasis, location of atelectasis, and radiographic changes 24 hours after bronchoscopy, i.e. without resolution, partial resolution or total resolution. Information was described both graphically, and numerically. The variable “radiological evolution” was used as explicative variable; when the variable response was continuous, a two-tailed one-way analysis of variance was performed, with α=0.05.
Results: Forty three patients with persistent atelectasis fulfilled the selection criteria. There was no improvement in 13 patients; there was partial resolution, in 27, and total resolution, in three. No statistical differences were found in terms of age, atelectasis or mechanical ventilation duration. Due to the small sample size, the rest of the variables could not be compared statistically.
Discussion: The diagnosis was established by means of the bronchoscopic study. Selective aspiration partially or totally solved the atelectasis in 30 of 43 patients.
