STAT CXR for Acute Respiratory Distress Elizabeth A. Lendermon
Clinical History • 44 yo white female • Multiple previous suicide attempts • Admitted after ethylene glycol ingestion • Initially intubated and mechanically ventilated but extubated and txd to floor on HD#8 • ARF 2o to ATN requiring intermittent HD • RLL PNA with blood cultures positive for pansensitive Acinetobacter and Strep. pneumo
Recurrent Respiratory Distress • Course c/b respiratory distress requiring return to MICU and attributed partially to volume overload with plan for aggressive diuresis and pulmonary toilet • 4 days after return to floor, pt. with continued tachypnea and O2 sat of mid 80’s on 100% vapotherm, no breath sounds on right • Differential dx included • PE • Pulmonary edema • Atelectasis
Diagnosis • Atelectasis on right secondary to mucus plugging • On bronchoscopy, mucus plug filling right mainstem bronchus from level of carina and extending into bronchus intermedius • Per report increased bilateral pleural effusions, right greater than left
Radiographic Features of Lung Collapse • Increased opacification of hemithorax in the setting of tracheal/mediastinal deviation toward the opacification • May see hyperinflation of adjacent lobes or elevation/ depression of hilum • RUL> upperward displacement of minor fissure • RML> minor and major fissures displaced toward each other, no mediastinal shift, can lose right heart border • LUL> aortic arch prominent • RLL/LLL> silhouetting of hemidiaphragm
Differential DX • Differential dx of chest opacification includes: • Consolidation • Pulmonary edema • Pleural effusion • Other alveolar filling processes (hemorrhage, ARDS) • Atelectasis • Extrathoracic stuff • Differential dx for this case: • Opacification 20 to new infiltrate or pleural effusion or both • Atelectasis 20 to pleural effusion or mucus plugging
