High Rates of Crush Syndrome Likely

  • Two to 15% of earthquake survivors in Haiti are likely to develop Crush Syndrome. Half of those survivors are likely to develop acute kidney failure. About 50% of those individuals will need dialysis.[1]
  • Crush Syndrome is unusual in American and European medical practice,[2] and it is unlikely Western medical doctors assisting in Haiti will have extensive experience with the condition.
  • Haitian rescue and medical personnel are unlikely to be able to meet the immediate, in-the-field or longer term management needs of survivors with Crush Syndrome due to extensive damage to facilities and lack of equipment.
  • Haitian health services need immediate support with IV triage units for trapped survivors and long term support through mobile dialysis units.
BACKGROUND:
Crush injuries and crush syndrome are common following entrapment in a structural collapse. Crush injury is “compression of extremities or other parts of the body that causes muscle swelling and/or neurological disturbances”. Lower extremity injuries account for most crush injuries (74%), with injuries to the upper extremities (10%), and torso (9%) are less typical.
[3]

Crush Syndrome includes localized crush injury along with systemic effects, first described in 1941 after study of London aerial bombing survivors.
[4] Crushing lasting more than 1 hour and/or sudden release of a crushed body part can cause the syndrome which includes rhabdomyolysis, a condition in which crushed muscles break down and release toxic muscle cell components into the blood resulting in kidney failure, heart rhythm abnormalities, metabolic abnormalities, and other organ dysfunctions.[5] When infections or other medical conditions complicate crush-related kidney failure, the mortality rate is near 55%.

Best practices for crush injuries in the field pre-hospital including providing intravenous fluids (IV) before releasing the crushed body part, especially if entrapment has been longer than 4 hours. Failure to recognize and treat Crush Syndrome is common,
[6] especially during rescue efforts by non-medical personnel, and typically increases the death rate.

Haitian Quake Status Updates

Caveat: Single internal source, not independently corroborated.

Update on US Embassy Status:
Internal sources confirm one American official killed in the earthquake. The US Embassy compound is operating. The US Embassy is the only foreign embassy in Haiti not severely damaged or destroyed. However, the former embassy building is severely damaged. Most embassy employee residences are destroyed or severely damaged

Update on Haitian Business and Government:
The President of Citibank in Haiti was severely injured and flown to Santo Domingo
The Parliament building and National Palace are destroyed.

Update on Lodging:
All hotels are damaged or destroyed.

Update on Hospitals and Heath Care:
All Hospitals in Santo Domingo are full. Most of the hospitals in Port au Prince are damaged or destroyed

Casualty Estimates:
Early estimations are 40,000 to 50,000 dead, but that number is likely to reach 100,000.

Haitian National Palace Destroyed; Psychological Damage Highly Likely

Haiti's 12 January earthquake badly damaged most governmental buildings in the nation's capital of Port-au-Prince. The Haitian National Palace, which like the US White House is the both the residence of the country's President and a symbolic governmental seat, collapsed.

According to research on neighborhood destruction in New Orleans after Hurricane Katrina[1], massive building destruction and deconstruction results in “wrenching” mental and emotional distress. Similar research conducted after the 1983 earthquake in Italy indicated that serious long-term psychological distress correlates directly with the severity of environmental damage and financial loss[2]. In addition, the care and respect with which destroyed buildings are managed following a disaster can either mitigate or worsen public distress.
