basal atelectasis

basal atelectasis

The collapse of basally oriented lung tissue, a common post-operative complication, which is associated with mucus retention due to poor pulmonary clearance, and secondary infection.

Clinical findings
Dyspnoea, tachycardia, pyrexia, cyanosis, pain on coughing, reduced expectoration, secondary bacterial infection, reduced chest movement especially on affected side, basal dullness, crepitation on breathing.

Imaging
Opacity of involved segment, mediastinal shift to affected side.

Risk factors
Abdominal distension, emphysema, intubation, irritation from anaesthetics, mechanical trauma to airways, muscle weakness, obesity, opiate use for pain, post-operative drowsiness, pregnancy, smoking, wound pain.
