You are working at a Level 1 Trauma Center; a 35-year-old female arrives via EMS from the scene of a motor vehicle accident. She was an unrestrained passenger, ejected 50 feet. She was hypotensive and hypoxic on scene with concern for head injury with a GCS of 7. She is clearly in shock on arrival with weak pulses, clammy skin, and a BP of 80/50mmHg, HR 140, sats 85%.  She is intubated, a chest tube is placed on the left (with improvement in O2 sats to 95%), and a pelvic binder is placed for suspected pelvic fracture. eFast demonstrates free fluid in the pelvis. Massive Transfusion Protocol (MTP) has been activated appropriately, and despite rapid delivery of 4 units Packed Red Blood Cells (PRBCs), 2 units of Fresh Frozen Plasma (FFP) and 1 pack of Platelets, she remains hypotensive, with presumed hemorrhagic shock. The patient is destined for the OR, but you ask yourself, in traumatic hemorrhagic shock, is there a role for vasoactive agents?

Shock is defined as circulatory failure leading to decreased organ perfusion.  In a shock state there is an inadequate delivery of oxygenated blood to tissues that results in end-organ dysfunction.  Effective resuscitation includes rapid identification and correction of inadequate circulation.  the finding of normal hemodynamic parameters (i.e. normal blood pressure) doe not exclude shock itself.  In this 17 minute and 26 second video, I will review the management shock - part 2b (Dobutamine, Milrinone, Vasopressin, Angiotensin II, & Selepressin).

The newly published 2015 AHA guidelines recommend that: “In IHCA, the combination of Vasopressin, Epinephrine, and Methylprednisolone and post-arrest Hydrocortisone as described by Mentzelopoulos et al. maybe considered; however, further studies are needed before recommending the routine use of this strategy (Class IIb, LOE C-LD)” Mentzelopoulos et al. [2][3] have published two separate randomized, double-blind, placebo-controlled studies out of Greece examining the role of this Vasopressin, Steroid, and Epinephrine (VSE) cocktail. These studies looked at in-hospital cardiac arrest for patients and enrolled patients immediately with non-shockable rhythms or patients in refractory VFib/VTach. The first study included 100 patients from a single center, while the second study included 268 patients from multiple centers.
