How to Cure a Corpse


If you’ve ever smelled a decaying corpse, you’ll appreciate the science of embalming. Nothing smells worse than a body in the full throes of decomposition. It’s a mélange of horrific odors: the gut-churning stench of putrid flesh mixed with a rank sweetness that clings to your mucous membranes. It’s a fetid gift that keeps on giving.

During my tenure as a firefighter/paramedic, we were often called to “check on the wellbeing of a patient.” In other words, “Grandpa hasn’t answered his phone in over a week. Can you guys swing by and check a pulse?”

As we’d pull up to the residence, we’d scan for newspapers. An accumulation on the front lawn was always a bad sign, as was a mailbox stuffed to overflowing. We’d approach the front door and pause to take a deep whiff. We could usually diagnose death by its odoriferous calling card (or as the medical examiners refer to it, the “smell of job security”).

So if a single body is capable of producing such rank odors, imagine a battlefield strewn with dead soldiers, their bloated bodies exploding under a scorching summer sun. Those were the conditions under which embalming first took hold on a grand scale.

But first, a quick retrospective… The Egyptians were embalming over eight thousand years ago as part of their intricate mummification process. After removing the brain and internal organs, the body was immersed in natron, a salt solution that would desiccate the tissues. Once the body was dried out, which usually took about a month, the wrapping of the body would commence. Egyptians believed a person’s soul would eventually return to his body, so it was only proper to preserve it for the soul’s homecoming. Unfortunately, only the wealthy were afforded proper mummification; the poor, they simply dunked in salt and hoped for the best.

Fast forward thousands of years to the bloody battlefields of America’s Civil War. It’s the 1860s and our nation is at war with itself. Union and Confederate soldiers are busy blasting each other to smithereens, resulting in a plethora of dead bodies that have no chance of keeping fresh for the long trip home. Mass graves were the usual solution. Large pits were dug and the bodies were laid to rest and quickly covered.

But as in so many realms of science, necessity was the mother of invention. Enter Dr. Thomas Holmes.

Dr. Holmes was a captain in the Army Medical Corps, assigned to Washington, D.C. He was the first to
practice embalming, which he achieved by injecting his “patients” with an arsenic solution that retarded the ravages of decomposition. His talents soon captivated President Lincoln, who was so enamored of the practice that he assigned Holmes and the Quartermaster Corps to provide embalming for Union soldiers and officers killed in battle. Holmes went on to embalm over four thousand before chucking his military career for a lucrative private practice.

So what is embalming and how is it achieved? Let’s explore.

Today, arsenic has been replaced by a formaldehyde solution (despite being deemed a carcinogen). Not only does it preserve the body, it also disinfects it. Disinfecting the corpse makes for safer handling; preserving the corpse makes it more appealing for those wishing to view the dead. It also provides a larger window in which to make funeral arrangements, freeing the undertakers from playing beat-the-clock against putrefaction.

Before the body is embalmed it is laid out, washed, and shaved, if necessary. The eyes are kept shut using eye caps, small plastic disks that are slipped under the eyelids. Perforations on the disks hold the lids in place, since nothing says “creepy” like a staring corpse. The mouth is closed with tacks that are placed in the upper and lower jaws and held together with wires. A special cream is then applied to the lips to hold them in place and prevent chapping.

Now the embalming can commence.

The embalming fluid enters the body via an incision into an artery; usually the carotid in the neck. A small pump holds the solution and is attached to the artery by a hose. A separate hose is inserted into a large vein, usually the femoral near the groin, and will empty into a nearby drain. The fluid (about three gallons) is pumped into the artery and circulated throughout the body, forcing out the blood and infusing the cells, before exiting through the hose in the vein. The process is complete when the entire blood volume is replaced by formaldehyde.

Idiot Alert!! There's a new trend in getting high: soaking cigarettes and joints in formaldehyde, which, when smoked, bring on hallucinations. Unfortunately, this also brings on seizures and coma, so play it safe and DON'T SMOKE ANYTHING!

But I digress... The incisions are closed and the pump removed, but one last step remains. A hollow tube formally called a trocar, which is attached to a suction unit, is inserted into the abdomen. With the flip of a switch, the gasses and liquids produced during early decomposition are magically sucked away and the belly is then flushed with a preservative. Now the body is properly embalmed and the technicians, wielding their combat-ready makeup kits, can move in to restore the corpse to its former lifelike splendor.

So now you know what awaits you, should you choose the traditional route of an open casket funeral. As for me? Harvest my organs, if possible, and throw me on the barbie. I’ve never been one for fuss and muss.

Here's a great book on the subject of all things "corpse."
