CAlcium and VAsopressin Following Injury Early Resuscitation (CAVALIER) Trial

Summary

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.

Eligibility

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 site at risk of hemorrhagic shock who meet the following criteria:

1A. Systolic blood pressure ≤ 90mmHg and tachycardia (HR ≥ 108) at scene, at outside hospital, during transport, or in emergency department of a participating CAVALIER trial site

OR

1B. Systolic blood pressure ≤ 70mmHg at scene, at outside hospital, during transport, or in emergency department of a participating CAVALIER trial site

AND

2.Blood/blood component transfusion initiated in prehospital setting or deemed clinically indicated within 60 minutes of arrival at the enrolling trauma center

AND 3. Clinical team deems Operating Room for major hemorrhage control procedure (e.g., laparotomy, thoracotomy, vascular exploration or extremity amputation) indicated within 60 minutes of arrival at the enrolling trauma center

AND

4\. Anticipated admission to intensive care unit (ICU)
