Typically infrarenal 

When ruptured – need blood, but allow for permissive hypotension – call for your aorta team

  • Heart blocks

Mobitz Type II and 3rd degree block need AICD/pacer

  • SVT

Vagal maneuver —> Adenosine (6, 12, 12) if hemodynamically stable

If unstable, synchronized cardioversion

  • Lefort fractures

3 types

Type III may have CSF rhinorrhea

Avoid NG tube placement

  • Chest tube output for OR indication

1500cc of output right away (~20cc/kg)

200 cc an hour for 3 hours (~3 cc/kg)

  • Boorhave syndrome

Hammans crunch

Massive vomiting or iatrogenic (most common)

Most common symptom is dyspnea

Most common EKG finding is sinus tachycardia

Most specific finding on EKG Is S1Q3T3, T wave inversions in the anterior leads

  • Status Epilepticus

Midazolam (can be given IM or intransal (great option for patient who doesn’t have access))

Lorazepam, Diazepam

Keppra (40-60 mg/kg IV. (Max dose of 4500 mg)), Fosphenytoin
