Penetrating Chest Trauma Flashcards
What is the pathophysiology of Hemothorax/Pneumotherax ?
Blood or air has accumulated in the pleural space
What has happened to the lung in Hemotherax/Pneumotherax ?
It has collapsed
What are signs & symptoms of Hemothorax/Pneumothorax ?
- SOB
- Increased HR
- Diminished breath sounds on the affected side
- Less movement on the affected side
- Chest pain
- Cough
What will show up on the X-ray in a client with either a Hemothorax/Pneumothorax ?
Hemothorax = Blood (Hem) Pneumothorax = Air (pneumo)
What is Subcutaneos emphysema ?
Air trapped in the tissue (usually neck, face, and chest)
- feels like rice crispies (crepitus)
What is the Tx for Hemotherax/Pneumothorax ?
- Thoracentesis
- Chest tube
- Daily chest x-ray
What is the Pathophysiology of Tension Pneumothorax ?
Pressure has built up in the chest/pleural space and has collapsed the lung
(pressure pushes everything to the opposite side - medicinal shift)
What does Tension Pneumothorax cause ?
Mediastinal shift
If the trachea is deviated due to mediastinal shift, what is it ?
An Emergency!
What are the causes of Tension Pneumothorax ?
- Trauma
- Too much PEEP (ventilator settings)
- Clamping a chest tube
- Inserting central venous lines
- Taping an open pneumothorax on all 4 sides without an air valve
What are signs and symptoms of a Tension Pneumothorax ?
- Subcutaneous emphysema
- Absence of breath sounds on one side
- Asymmetry of thorax
- Respiratory distress
- Cyanosis
- Distended neck veins, or JVD
Tension pneumothorax can be what ? and why ?
Fatal
as accumulating pressure compresses vessels –> decreases venous return –> decreases cardiac output
What is the Tx for Tension Pneumothorax ?
- Large bore needle is placed into the 2nd intercostal space (by the PCP) to allow excess air to escape
- Treat the cause (chest tubes will be inserted)
Open pneumothorax is also known as what ?
Sucking chest wound
What is the Pathophysiology of an Open Pneumothorax (sucking chest wound) ?
Opening through the chest that allows air into the pleural space
