Abstract
Objective
To analyze the radiological aspects of pulmonary atelectasis in newborns on
mechanical ventilation and treated in an intensive care unit, associating
the characteristics of atelectasis with the positioning of the head and
endotracheal tube seen on the chest X-ray, as well as with the clinical
variables.
Materials and Methods
This was a retrospective cross-sectional study of 60 newborns treated between
1985 and 2015. Data were collected from medical records and radiology
reports. To identify associations between variables, we used Fisher's exact
test. The level of significance was set at p < 0.05.
Results
The clinical characteristics associated with improper positioning of the
endotracheal tube were prematurity and a birth weight of less than 1000 g.
Among the newborns evaluated, the most common comorbidity was hyaline
membrane disease. Atelectasis was seen most frequently in the right upper
lobe, although cases of total atelectasis were more common in the left lung.
Malpositioning of the head showed a trend toward an association with
atelectasis in the left upper lobe.
Conclusion
Pulmonary atelectasis is a common complication in newborns on mechanical
ventilation. Radiological evaluation of the endotracheal tube placement
provides relevant information for the early correction of this
condition.
