Case Reports in Pulmonology
|November 29, 2023
Summary
This case study shows a novel use of cryoprobes for clearing blood clots from chest tubes in a patient with COVID-19 pneumonia. This technique successfully restored chest tube function and resolved a persistent pneumothorax.
Area of Science:
- Pulmonology
- Critical Care Medicine
- Interventional Pulmonology
Background:
- Chest tubes are crucial for managing pneumothorax, but can become occluded.
- COVID-19 pneumonia can lead to complex respiratory complications, including pneumothorax.
Observation:
- A 72-year-old male with COVID-19 pneumonia developed recurrent pneumothorax despite chest tube placement.
- Standard chest tube interventions (flushing, suctioning) failed to restore patency.
- Flexible bronchoscopy revealed bilateral chest tube occlusion by blood clots.
Findings:
- A cryoprobe, guided via a flexible bronchoscope, was used to remove obstructing blood clots from the chest tubes.
- Successful clot removal restored chest tube patency.
- Resolution of the pneumothorax was achieved following the intervention.
Implications:
- Flexible bronchoscopy with cryoprobe technology offers a potential solution for refractory chest tube occlusion.
- This approach may be valuable in managing complex pleural space disorders, particularly in critically ill patients.
- Highlights innovative applications of bronchoscopic tools in critical care settings.

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
