The Medical Consequences of an Earthquake. Trauma, Crush Injuries, Infectious Disease and Stress Disorders: A Population-Based C
Posted Jan 14 2010 1:50pm
Count on the science of medical epidemiology to leave no manmade or natural disaster go unexamined. Examples include the medicalization of nuclear war, inquiries into the risks associated with depletion of the ozone layer and more recent alarming reports on 9-11 and global warming. Given the epic tragedy unfolding in Haiti, the Disease Management Care Blog wondered if a) earthquakes were also a topic in the medical literature and, if so, b) what it could tell us about them from a population-based health perspective.
The answers are yes and lots.
It looks like there are four stages to a disaster like this.
2. What follows next are the crush injury victims who are pulled out of the rubble. Survival with chest or abdominal trauma is relatively uncommon, so once again, it'll be these victims limbs that require treatment. Laying in one position and being unable to move for hours or days with or without crush injuries can also lead to considerable swelling or the arm or leg, which often necessitates 'fasciotomies,' i.e., surgically opening the skin (explanation and picture) to accomodate the swelling. This allows this edema to run its course without squeezing off the local blood supply. These injuries can also lead to the release of high amounts of muscle protein into the blood stream (called 'rhabdomyolysis'), which is toxic to the kidneys. Avoiding kidney shut-down (failure) involves complicated medical treatment which is often out of the reach of first responders. If the failure turns out to be permanent as the hours to days unfold, the lack of access to dialysis is a death sentence for those victims who are otherwise joyously rescued alive from the rubble.
Despite the initially insurmountable logistics, this can be the Obama Administration's finest hour. Based on what the DMCB is reading, their planning should emphasize finding, assembling and equipping local 'first responders' who can supply first aid in the streets. In addition, medical experts with knowledge of treating trauma and, in particular, orthopedic injuries are critically needed right now. They should be followed by other surgeons as well as health providers that can manage the rhabdomyolysis and, if possible, provide emergency dialysis. Planning for camps should be starting by now to head off the risk of overcrowding, poor sanitation and communicable disease; vaccines should be on the way and special services for HIV and TB need to be arranged, along with mental health services.
The DMCB hopes and prays for the brave people of Haiti.
