Hemodynamics in Helicopter Emergency Medical Services (HEMS) Patients Undergoing Rapid Sequence Intubation With Etomidate or Ketamine.

Background: Rapid sequence intubation (RSI) is performed by helicopter emergency medical services (HEMS) providers to establish airway control. Common induction agents are etomidate and ketamine, both touted to have relatively stable hemodynamic profiles. Limited data comparing these medications in the air medical setting exist.

Absent Inferior Vena Cava Leading to Recurrent Lower Extremity Deep Vein Thrombosis in a United States Marine.

Introduction: Anomalies of the inferior vena cava (AIVC) are rare but well-recognized anatomic abnormalities that can lead to clinically significant deep vein thrombosis (DVT) in a subset of otherwise healthy patients. This report illustrates an uncommon congenital anomaly that military clinicians should consider when evaluating unprovoked DVT in young patients.
