Learn about the key principles and approach to managing hemoptysis in the emergency department. Topics include differentiating hemoptysis from pseudohemoptysis, the use of tranexamic acid, suctioning blood from the airway during intubation, the role of bronchoscopy, and how hemorrhage control strategy changes with pulmonary embolism. The podcast also discusses preparations and equipment for managing hemoptysis, the utility of CT scans and point-of-care ultrasound, and various strategies for intubation and airway management. Additionally, it covers the importance of reliable suction, alternative options if inadequate, and the approach and interventions for managing hemoptysis.

Identifying the Source of Bleeding: Distinguishing Hemoptysis
When dealing with hemoptysis cases, it is important to first determine the source of bleeding. Clinical clues such as a history of coughing before blood appears, the appearance of the blood itself, and observing if there is blood dripping from above can help differentiate between upper airway, lower airway, or gastrointestinal sources of bleeding. A nasopharyngoscopy or video bronchoscopy can provide further visualization of the airway and help identify the bleeding site.
Characteristics and Management of Massive Hemoptysis
Massive hemoptysis is a respiratory emergency caused by the patient drowning in their own blood. The key focus is on maintaining the patient's airway and preventing hypoxia. Rapid sequence intubation (RSI) using a laryngoscope and proper patient positioning helps secure the airway. Suctioning large volumes of blood is essential, and specialized tools like the DeCanto suction catheter or a maconium aspirator can aid in effective suctioning. In extreme cases where blood obstructs the view, a supraglottic airway can provide temporary oxygenation while definitive measures are taken.
Tools and Techniques for Airway Management
When managing massive hemoptysis, using a large single-lumen endotracheal tube is recommended. Double-lumen endotracheal tubes and bronchial blockers are generally not necessary and can complicate the procedure. Good suctioning tools, such as the DeCanto suction catheter or a maconium aspirator, are crucial to clear the airway of blood. Maintaining proper patient positioning during intubation and having access to a powerful suction system are key components for successful airway management.
Initial Assessment and Notifying the Per Team
In the emergency setting, when faced with a patient experiencing massive hemoptysis, the first priority is to quickly assess if immediate airway management is necessary. If the patient is unable to control the amount of blood through coughing, immediate intubation may be required. Simultaneously, it is important to notify the appropriate medical professionals and teams, such as the Per Team (if available), pulmonology, CT surgery, radiology, and interventional radiology. This coordinated approach ensures that the necessary experts are alerted and can be involved in the patient's management.
Determining Safety for CT Scan and Airway Management
After initial steps have been taken, including reversing coagulopathy and administering nebulized TXA, the decision must be made regarding the safety of sending the patient for a CT scan with an unprotected airway. If the patient is deemed safe, they can proceed to the CT scan with someone accompanying them. However, if safety is a concern, alternative approaches must be considered. This may include intubation followed by CT, attempting a bronch in the bedside, or bypassing the CT scan and proceeding directly to interventional radiology. Ultimately, the decision should be made collaboratively, taking into account the patient's specific condition and stability.
Key principles and approach to management of both non-massive and massive hemoptysis with Dr. Scott Weingart and Dr. Bourke Tillmann, who answer questions such as: What are the factors to consider in the decision to intubate patients with massive hemoptysis? How can one reliably distinguish hemoptysis from pseudohemoptysis? What is the evidence for tranexamic acid in patients with hemoptysis? What are the best strategies for suctioning blood from the airway to improve visualization during endotracheal intubation in crashing hemoptysis patients? What is the role of bronchoscopy and how should it be integrated into the hemoptysis management algorithm? How does one's hemorrhage control strategy change when pulmonary embolism is the underlying diagnosis? and many more...
