Tension Pneumothorax
PED-25
Diagnosis
May see:
- Unilateral breath sounds
- ↑ HR
- ↓ SpO2
- ↓ BP
- Tracheal deviation
- Mediastinal shift
Perform immediate needle decompression, then chest tube placement
Needle decompression, 2nd rib space superior to 3rd rib, mid-clavicular line
- 14-16g angiocath for teens/adults
- 18-20g angiocath for infants/children
Stop N2O; increase O2 to 100%
Secure airway with endotracheal tube
Reduce positive ventilation pressure
Consider CXR, Lung Ultrasound, transillumination to confirm diagnosis
Administer vasopressors for circulatory collapse
Chest tube insertion, 5-6th intercostal space, mid-axillary line
If no improvement in hemodynamics after a rush of air, consider:
- Needle decompression of contralateral side
- Presence of pneumopericardium
- Scan both lungs with ultrasound or transillumination to evaluate for alternate side or insufficiently decompressed pneumothorax
Consider DDx
Crisis Management (If Severe)
Notify surgeon, call for help and code cart
Call for Transesophageal Echocardiography
Start chest compressions
Give epinephrine 10 MICROgrams/kg IV/IO
If cardiac arrest, go to CARDIAC ARREST
Consider ECMO
Differential (Partial)
- Pneumothorax on contralateral side
- Pneumopericardium
Lung Ultrasound Instructions
- High frequency probe, place longitudinally on chest, 2nd intercostal space. Slide probe downwards to observe pleural sliding
- If see pleural sliding, 100% positive predictive value no pneumothorax
- If no pleural sliding, consider pneumothorax, ARDS, fibrosis, acute asthma
