Remote Damage Control: Civilian Experience in

the Pre-Hospital Setting

No Disclosures

Objectives

•  Indications for treatment with blood products for traumatic hemorrhagic shock in the pre-hospital setting

•  Monitoring devices used for coagulopathy and shock •  Therapeutics utilized in these patients for pre-hospital

treatment of casualties •  Evacuations of long durations compared to rapid ones •  Methods of implementation to improve rapid

incorporation of recently initiated changes in practice

Remote Damage Control Resusc

•  Austere/rural environment patients •  Modified transfusion strategy •  Different than those with scene/pre-hospital time < 30

minutes •  Limited resources available •  Lack of plasma availability •  40% of the population, 60% of the trauma mortality

•  Current treatment options for uncontrolled hemorrhage in this environment are very limited

•  >75% of combat fatalities occur in the field

Hartford Consensus February 2013

•  Leaders in law enforcement, EMS, military and the American College of Surgeons

•  Recommendations for civilian organizations to improve survival during active shooter scenarios

•  Stress “the importance of early and definitive hemorrhage control to maximize survival in the victims….”

Hartford Consensus THREAT •  T - Threat suppression •  H - Hemorrhage Control •  RE - Rapid Extraction to safety, •  A - Assessment by medical providers •  T - Transport to definitive care

Coagulopathy on Presentation

•  An initial INR ≥ 1.5 reliably predicts those military casualties who will require MT.

•  Pts who have a significant injury present with a coagulopathy.

•  Severity of injury and mortality is linearly associated with the degree of the initial coagulopathy.

Background

MacLeod JBA et al. Early Coagulopathy Predicts

Mortality in Trauma J Trauma 2003

Brohi K et al. Acute Traumatic Coagulopathy

J Trauma 2003

By the time of arrival at the ED, 28% (2,994 of 10,790) of trauma patients had a detectable coagulopathy that was

associated with poor outcome

Background

de Biasi et al. Early Coagulopathy Predicts Mortality in Trauma

Transfusion (Epub, Accepted 2010)

Mortality was associated with worse Plasma Deficit &

The efficacy of the Plasma Repletion occurs within hours

DoD Learned About Thawed Plasma

•  Thawed plasma is FFP that is kept for up to 5 days at 4°C •  This product should be present upon arrival of the casualty in

the ED •  should be used as a primary resuscitative fluid started in the ED

•  This approach not only addresses the metabolic abnormality of shock, but initiates reversal of the coagulopathy present in the ED.

•  Thawed plasma is used in theater •  The DoD Level 1 trauma center uses this product

•  Decreases waste by 60-70%

Early Use of Blood in the Pre-hospital Setting

•  Mayo Clinic Experience •  1993-96 retrospective review •  Criteria: Hgb<10, shock, hypotension after

resuscitation •  ~2100 helicopter flights, 94 patients received

PRBC’s (4%, 91% interfacility transfer) •  48% trauma patients, 25% GI bleed, 38% AAA •  Hgb increased from 8.9 to 10.2 after 2 PRBC •  No transfusion reactions or complications •  Average 12 u PRBC after admision •  Age of RBC is < 14 days

Air Med J 1998 Zietlow and Berns

Age of Blood and Procoagulant Microparticles

•  Historically, PCMP increases with age of blood

•  52 trauma patients vs 22 volunteers •  Higher PCMP with injury; no difference

between transfused (n=19)/not transfused •  24 hour PCMP decreased with transfusion

•  No decrease if no transfusion •  Difference widened with increasing transfusion

Catchment Area

Rationale Coagulopathy & the “Golden

Hour”

•  Trauma Induced Coagulopathy (TIC) predicts mortality

•  Plasma and RBC resuscitation should occur early in the hemorrhagic / coagulopathic pt

•  Catchment area / Rural location provides geographic obstacles

•  Regional plasma deficiency

Protocol – ED Phase •  Thawed Plasma Program •  Developed in Feb 2008 with input from:

- Blood Bank Team - Transfusion Medicine - Medical Transport - Trauma, Critical Care and General Surgery

•  Initial 9 months were restricted to in-hospital Emergency Department use

•  Medical and Surgical emergencies - Safety concerns - Utilization of resources

•  Product immediately available in the Trauma Resuscitation Area: - 4 units thawed plasma (A+) - 4 units PRBCs (0 negative)

•  Order of transfusion for trauma patients was: •  2 units PRBC •  2 units thawed Plasma •  2 units PRBC •  2 units thawed Plasma

Protocol – Helicopter Phase

pRBC + Plasma 1.  Hypotension (single reading

of systolic blood pressure < 90mmHg)

2.  Tachycardia (single reading of heart rate ≥ 120)

3.  Penetrating mechanism 4.  Point of care lactate ≥ 5.0

mg/dl 5.  Point of care INR ≥ 1.5

Indications for PRBC and Plasma administration in adult trauma patients

Plasma Alone 1.  Point of care INR ≥ 1.5 2.  Stable Hemodynamics

Waste Prevention Division of Transfusion Medicine monitors

usage

- Thawed plasma is removed from the satellite blood refrigerator on Day #3 and sent to the Operating Theater for immediate use.

Mayo Helicopter Transfusion Criteria

RESULTS

•  5 for hemorrhage •  3 required massive transfusion (> 10 units/24 hours)

•  5 pts transfused for history of trauma and coumadin use

•  All 4 deaths were in this group

•  All pts entered into protocol required ongoing blood product transfusion after arrival to the hospital.

Group A Plasma Transfusion Discussion

•  Emergency plasma use is increasing

•  Limited access

•  “New” universal

donor resulted in 97.6% reduction in AB plasma use

Group A Plasma Transfusion Discussion

•  Group A plasma has equivalent outcomes to group AB •  Incompatible transfusions occurred •  No hemolytic reactions •  Similar mortality •  Similar immunogenic complications

•  Limitations

•  Small comparison group

•  Type II error potential

•  Post-hoc analysis

CRASH-2 Study Lancet, Online Article, 2010

•  Prospective, randomized controlled trial •  20,211 patients •  TXA significantly reduced all cause mortality from 16.0% to

14.5% •  TXA significantly reduced death due to bleeding from 5.7% to

4.9% 43

Beilman Study •  Over a 15-month period, seven Level I trauma centers in

the USA enrolled 383 patients, 50 of whom developed MODS

•  StO2 below 75% indicates serious hypoperfusion in trauma patients

•  78% of patients who developed MODS, and 91% of patients who died, had StO2 below 75% in the first hour

•  Trauma patients who maintained StO2 above 75% within the first hour had an 88% chance of MODS-free survival

Current Status •  All 3 Mayo helicopter bases carrying 3 PRBC

and 3 thawed plasma •  All 3 use same transfusion triggers •  All 3 use i-Stat INR and ABG cartridges •  All 3 carry TXA; uses similar triggers but has

some limitations for use •  Just added StO2 as a trigger •  Limited waste at all 3 sites •  No crystalloid for those with hemorrhage •  Tourniquets and Combat Gauze on all 3 ships

The Future •  Freeze dried plasma? •  Whole blood? •  Platelets? •  Prothrombin complex concentrates?

Why Freeze Dried Plasma?

Remote Damage Control Resuscitation!

Implementation of Change •  Consensus •  Review of the literature and our own data •  Practicality and safety are first order of

business with best interest of patient in mind •  Continuous monitoring of program •  Education of all health care providers •  Willingness of blood bank and transfusion

medicine to consider novel use of products

Overall System Results •  Current era (2011) compared to the era

before pre-hospital plasma •  Referrals up (838 vs 998*) •  ISS up (9 vs 12*) •  Mortality same (2.5% vs 2.2%) •  Observed decline open abdomen (under study) •  Observed decline in massive tx (under study) •  Arrival TEG improved? (under study)

Summary •  Trauma patients die from shock •  Our job is to limit preventable trauma death •  First, identify the patient in shock •  Pre-hospital resuscitation with plasma can

prevent the trauma induced coagulopathy and limit the risk of death due to hemorrhage

•  Making dried plasma available in the rural and pre-hospital/austere environment will save lives

Thank You!
