in Disasters:

Lessons learned and

applied

For the Renal Disaster Relief Task Force

(RDRTF)

International Society of Nephrology (ISN)

Médecins Sans Frontières (MSF)

Management of crush-related

injuries after disasters

1

DISASTER

Sudden calamities

producing extensive

damage, loss and

distress

• Natural

– Earthquakes

– Landslides

– Avalanches

– Hurricanes

– Tornadoes

• Man-made

– War

– Mining

– Tunnel collapse

– Terrorism, torture









GLOBAL SEISMIC HAZARD MAP









• Californian fault

• The whole Mediterranean

• South-East Asia

• The Far-East

• Tehran Science, 2000; 288: 661-5.

MAN-MADE DISASTERS









Sudden collapse of an eight-story building:









80% die instantly

10% minor injuries

7/10 develop

10% major injuries

Crush syndrome

Ron et al, Arch Intern Med, 1984









3

Crush syndrome =

muscular destruction

after trauma



Rhabdomyolysis =

Disintegration of striated

muscles with release of

muscular content



Myoglobulin =

18,000 D oxygen carrier,

filtered by the glomerulus,

may obstruct the tubules









Crush Syndrome History

First described in

German literature in

victims of Messina

earthquake of 1909



WW I Germans

noted traumatic

rhabdomyolysis

(military medical

literature)

FOLLOWING DISASTERS:

CRUSH SYNDROME



the second most frequent cause of death

(following direct trauma) Ukai, Ren Fail,1997









RENAL DISASTER

Solez et al, KI, 1993









THE ARMENIAN EARTHQUAKE

• Death toll: 25,000 ?

• Crush cases: 600 ?

• Many crush pts. died due to lack of dialysis



Help not effective

Need for preplanned logistic organization







RENAL DISASTER RELIEF TASK FORCE

Solez et al, KI, 1993









7

The natural disaster is the catastrophe

that everyone sees. People rarely see the

arrival of overmanned, unorganized

assistance groups, each with its own

game plan, whose first question is “ where

do we eat and sleep?”

Pierre Pradier

Directeur- Général

Médeçins du Monde

RENAL DISASTER RELIEF

TASK FORCE (RDRTF): AIMS

• To offer material and personnel support in

any mass disaster where renal problems

are prevalent

• The RDRTF has lists of volunteers

(nephrologists/intensivists, nurses,

technicians)

• The RDRTF has a stock of hardware

(dialysis machines, RO-systems) to be

dispatched in case of disasters









MAJOR LOGISTIC STEPS FOLLOWING AN EARTHQUAKE

US Geological services – earthquake detection

GLOBAL COORDINATION (A)









Chairman RDRTF





Initial estimation of number of Advance scouting

crush syndrome victims nephrologic team







Local key person







Reporting local conditions /

assessing magnitude of the problem

LOCAL COORDINATION (B)









Anticipation of the needs for support

(i.e. medications, blood products)





Inform RDRTF Branch Chairman (international support)

Inform local authorities (national support)





Support is offered, if needed









9

MAJOR POINTS OF

ATTENTION FOR TASK FORCE

INTERVENTIONS









SEVERITY ASSESSMENT

• Intensity of the disaster

• Population density of the region,

Many factors contributive • Structural characteristics of buildings

• Timing (moment) of disaster

• Efficacy of rescue activities

Noji et al., 1990; Nadjafi et al., 1997









Gujarat Earthquake: Bam Earthquake: September 11 terrorism

Death: 19,727, Cr.:35 Death: 26,000; Cr.: 124 Death: >3,000; Cr.: 1

Viroja et al, WCN Abstracts, 2001 Argani et al, JASN, 2004 Goldfarb and Chung, Am J Med, 2002

RATIO DIALYZED/DEATHS (x 1,000)



Location Country Year Ratio

Spitak Armenia 1988 9.0-15.4

Northern Iran Iran 1990 3.9

Kobe Japan 1995 24.6

Marmara Turkey 1999 28.1

Chi-Chi Taiwan 1999 13.3

Gujarat India 2001 1.7

Boumerdes Algeria 2003 6.6

Bam Iran 2003 3.7

Kashmir Pakistan 2005 2.4

Yogyakarta Indonesia 2006 <0.1









MEDICAL INTERVENTIONS AT THE DISASTER FIELD

(For Prophylaxis of Crush Syndrome)



EARLY FLUID ADMINISTRATION

IS OF VITAL IMPORTANCE !



(1 L / hr saline)



• After the rescue alkaline solution

• Adequate urine response ⇒ + mannitol 8 - 12 L/day

• Less aggressively (4 - 6 L/day) if monitoring indufficient

• CVP measurements

Better and Stein, NEJM, 1990 Vanholder et al, Kidney Int, 2000









11

STATUS OF LOCAL HEALTH FACILITIES /

TRANSPORT POSSIBILITIES - I



Hospitals are damaged









• Field hospitals??

“de novo dialysis units” • Not useful for crush?

⇒ impractical









STATUS OF LOCAL HEALTH FACILITIES /

TRANSPORT POSSIBILITIES - II



• Aftershocks may further damage hospitals

• Keeping positions open for untransportable cases

• Locally treated patients have a higher risk of mortality

Kuwagata et al, 1997



Transport of victims in disaster conditions may be problematic









Administer potassium binders before transportation !









12

Supplementation of

MEDICAL MATERIAL and PERSONNEL



International relief ≠ functional help



• Guatemalan e. ⇒ 90% drugs useless (unsorted) Seaman, Injury, 1990

• Armenian e. ⇒ 70% useless (expired or damaged) Auiter, Lancet, 1990





International personnel support ⇒ useful or harmful



Local / Global integrated responses are mandatory !
