Bronchospasm
PED-05
Diagnosis
May have:
- ↓ EtCO2
- Upslope stage III EtCO2
- ↑ airway pressures
- ↓ SpO2
Non-Intubated
If severe, consider intravenous epinephrine 1-2 MICROgrams/kg IV (MAX 1 mg) or 10 MICROgrams/kg subcutaneous/intramuscular (MAX 0.5 mg)
Administer supplemental oxygen
Auscultate the chest, differentiate from stridor/extrathoracic airway obstruction
Consider inhaled albuterol (with spacer) 2.5-5 mg. If severe, 5-20 mg/hr inhaled
Consider chest radiograph
Consider IV steroids: methylprednisolone 1mg/kg IV (MAX 60 mg) or dexamethasone 0.15-0.25 mg/kg (MAX 16 mg)
If severe, consider ICU and/or advanced airway management
Consider DDx
Intubated
If severe, consider epinephrine 1-2 MICROgrams/kg IV (MAX 1 mg)
Consider inhaled albuterol 4-10 puffs as needed
Consider deepening anesthetic
Auscultate the chest
- Equal breath sounds?
- Endobronchial ETT?
- Wheezing?
Check the ETT
- Kinked?
- Secretions/blood in the ETT? Need for suctioning?
If needed, give ketamine 1-2 mg/kg IV
Consider IV steroids: methylprednisolone 2mg/kg IV (MAX 60 mg) or dexamethasone 0.15-0.25 mg/kg (MAX 16 mg)
Consider chest radiograph
For refractory bronchospasm, consider magnesium 50-75 mg/kg (MAX 2 grams) bolused over 20 minutes, (CAUTION, may cause hypotension)
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
