Purpose: to remove the word

“RESUSCITATION” from your vocubulary.

Or at least as you have used it in the past

RESUSCITATION

Historic Concept

• “Get the patient in shape so that surgery will be tolerated”

• This is an URBAN LEGEND

TraumaTrauma(Abandon this concept)

What is RESUSCITATION ?

Historic Concept

• Assure an airway

• Control Bleeding

• Raise the BP (? Towards normal or HIGHER)

TraumaTrauma

OVER

FluidsHow Much (1963-1995)

• 2 LARGE BORE IVs

• 3 liter LR (or NS) in ambulance

• 3 liter LR (or NS) in ER

• “If a little bit is good a lot is better”

• Massive transfusion protocols

• End Points vague

TraumaTrauma

Historic Approach

• 20th Century Algorithm– Replace blood with

crystalloid in 3:1 ratio

– No concern for impact on bleeding

RESUSCITATION ?

Historic How Accomplished ?

• Position

• Dressings & tourniquets

• Medications (vasoactive)

• Fluids, LOTS of fluids

TraumaTrauma Lots of Complications

Fast FORWARD to

the PAST

TraumaTrauma

Examine the PATIENT

TraumaTrauma

Recognize the patient in need of EMS or EC, or OR

“Intervention”

…and who does NOT need it

TraumaTrauma

Less than 4% of ALL trauma patients actually need or

benefit from “Resuscitation”

(Whatever that is)REALLY

TraumaTrauma

Problems

NEW

Classification

MEDICAL DISASTER RESPONSE

More than 90% of ALL

trauma patients need NO

“Resuscitation”

TraumaTrauma

Some foundations for “resuscitation”

TraumaTrauma

William Shakespeare

TraumaTrauma

…..or not so new

“ ..to stop his wounds, lest he do bleed to death.”

Shakespeare, The Merchant of Venice, Act IV, Scene I

1597

Stop the Bleeding – Go to OR

Stop the Bleeding

Walter Cannon

TraumaTrauma

Cannon – World War I

"The injection of a fluid that will increase blood pressure has dangers in itself. Hemorrhage may not have occurred to a marked degree because the blood pressure has been too low to overcome the obstacle offered by a clot.“

Less Resuscitation is Best

WWI lessons

• Cannon – JAMA

• “It is wasteful of time, resources and people to give fluid prior to operative control of hemorrhage.”

WW IIOffice of the

Surgeon General

TraumaTrauma

Office of the Surgeon General, U. S. Army

WWII lessons• 2 reports• “BP should not be elevated and

fluid not given till operative control of bleeding”

• Do not pop the clot and loose precious blood

1954-1960CPR

External Cardiac Compression

(Elan, Safar, Kouwenhoven)

TraumaTrauma

Fluid 3:1 Rule

• DALLAS

• Original studies

–Shires, 1963

• Described three isotope model

• Showed extracellular repletion with crystalloid essential for survival

So? Does it work for trauma?

NotReally

TraumaTrauma

The Three to One Rule

• Original studies – Shires, 1963

• Described three isotope model

• Showed extracellular repletion with crystalloid essential for survival

Fluid 3:1 Rule

• Developed in “controlled hemorrhage” model

• NEVER tested in people

• Pre-dated EMS and Trauma Systems

• Became “doctrine” without any class I, II, or III data

RESUSCITATION ?

Historic Assessment

A - ALL IVs FULL Flow

B – BP higher than normal

C – Chart Looks good

TraumaTraumaNOW Call Surgeon

AMAZING-Patient’s surgery

DELAYED until “resuscitated” in EMS,

EC, or ICU

TraumaTraumaThis is a NO NO

HISTORIC

• Vietnam experience

• Approach to hypotension was 2 large caliber IVs

• Give crystalloid as rapidly as possible.

And NEW Problems happened

Resuscitation CoursesATLSACLSPALS

(12 others)Almost identical cirriculum

Teach ABCs

Encourage FLUID bolus

Lots of Urban Legends

TraumaTrauma

“Fill the tank”“Fluid Challenge”

Commonly quoted phrases

TraumaTrauma

Three Peaks in Mortality

LethalMOF

Early “resuscitation”

Pop the Clot

Early fluid type DOES effect Death & MOF

Residual, quiet continuing questions

(Did not join bandwagon)

TraumaTrauma

1960s “aggressive fluid administration in uncontrolled hemorrhage resulted in increased mortality”

Shaftan GW, Chiu CJ, Dennis C, Harris B. Fundamentals of physiologic control of arterial hemorrhage. Surgery 1965; 58: 851-856.

Milles G, Koucky CJ, Zacheis HG. Experimental uncontrolled arterial hemorrhage. Surgery 1966; 60: 434-442.

Permissive Hypotension

• 1980s and 1990s- rodent & swine models of hemorrhagic shock

• Aggressive fluid resuscitation in uncontrolled hemorrhage resulted in increased mortality & morbidity

1994BIG BOMB

Keeping the BP low saves lives – Do NOT POP

the CLOT

Permissive Hypotension

• 1994 – 1st clinical evaluation offluid restriction in uncontrolledhemorrhage

Mattox: Immediate versus delayed fluid resuscitation for hypotensive patients with penetrating torso injuries. N Eng J Med. 1994;331:1105-9

Permissive Hypotension(Bickel et al)

598 patients with penetrating torso injury & systolic BP ≤ 90 mmHg in prehospital setting

Patients randomized to receive high-volume fluids, or fluids delayed until patient in OR

Permissive Hypotension

• Results:– Group Divisions

• Delayed: n=289• Standard fluids: n=309

– Survival:• Delayed: 70%• Standard fluids: 62%

– Complications:• Delayed: 23%• Standard fluids: 30%

patient going from Ambulance dock to the OR

or ICU

FluidsWHAT KIND?

• Ringer’s Lactate• Normal Saline• Dextrans, Starches, Gelatin, Albumin• Hypertonic solutions• Designer fluids• Blood & blood products• Hemoglobin substitutes

TraumaTrauma

Crystaloids

Advantage• Readily available• Inexpensive• Repleats

intravascular & interstitial volume

• Encourages Urinary flow

Disadvantage

• Does not stay in vasculature

• Need LARGER volumes

• Edema

• Inflammation

TraumaTrauma

Non-Protein Colloids

Advantage• Readily available• Equal to protein

colloids (?)

Disadvantage• Expensive• Coagulopathy• Long half life• RES activation• Short dwell time• Anaphalaxis• Cross Match

problems

TraumaTrauma

Protein Colloids

Albumins

5% human serum albumin

25% human serum albumin

Gelatins – Not available in US

FluidsHow Much (2012)

• Check for pulse & CNS• If absent- give fluid bolus (25

ml) until pulse (or CNS) returns• Use Blood & Plasma (1:1)• Have defined end points

-? NIR, Base Deficit, Lactate, (NOT BP)

• Markedly limit (or NO) LR & NSTraumaTrauma

Permissive Hypotension

Systolic BP <80 mm Hg

“Pop the Clot” @ 80/-

Low MAP is tolerated - compensatory flow and metabolism Fluid infusion rate not to exceed 45 ml/min (no benefit to faster rates - even if systolic BP is ~ 40 mm Hg)

Permissive Hypotension

• Elevation of BP to pre-injury levels (absent definitive hemostasis) is associated with:

– Progressive and repeated re-bleeding

– Hypoxemia from excessive hemodilution

BALANCED

Major NEW Lesson

• Replace blood loss with (FRESH) blood

• Match blood with FFP (1:1)

• For each unit of blood – give 1 unit of platlets (1:1:1)

• RESTRICT crystalloidTraumaTrauma

Summary• Novel “New” Concepts WORK

• Abandon the word Resuscitate

• Keep treatment–Functional

–Simple

–Effective

• Stop hemorrhage

Hurdsfield, NDJanuary 15, 1992

“There is nothing more difficult to take in hand, nor perilous

to conduct, nor more uncertain in its success than

to take the lead in introduction in a new order of
