The CAlcium and VAsopressin following Injury Early Resuscitation (CAVALIER) Trial is a proposed 4 year, double-blind, mutli-center, prehospital and early in hospital phase randomized trial designed to determine the efficacy and safety of prehospital calcium and early in hospital vasopressin in patients at risk of hemorrhagic shock.
Resuscitation strategies for the acutely injured patient in hemorrhagic shock have evolved. Patients benefit from receiving less crystalloid in favor of blood transfusions with balanced ratios of plasma and platelets or whole blood resuscitation. These resuscitation practices are termed Damage Control Resuscitation and have been incorporated into resuscitation protocols in Level I trauma centers across the country. Damage Control Resuscitation represents standard practice for military and civilian trauma. Despite these changes, deaths from traumatic hemorrhage continue to occur in the first ho…
Inclusion Criteria: Prehospital Phase: Injured patients at risk of hemorrhagic shock being transported from scene or referral hospital to a participating CAVALIER trial site who meet the following criteria: 1A. Systolic blood pressure ≤ 90mmHg and tachycardia (HR ≥ 108) at scene, at outside hospital, or during anticipated transport to a participating CAVALIER trial site OR 1B. Systolic blood pressure ≤ 70mmHg at scene, at outside hospital, or during anticipated transport to a participating CAVALIER trial site Early In-Hospital Phase: Injured patients at a participating CAVALIER trial si…
