→ Embalming Tissue Gas- Training Video

Embalming tissue gas training
Embalming Tissue Gas -Training Video from Your Mortuary Magic Store on Vimeo.

Twas the night after Christmas,
and all through the night,
there was bacteria growing causing great fright,
they call it tissue gas and for good reason,
we share our training for tis' the season,

"Embalm the Nightmare like a Dream"

→ Human Pressure Cooker - Physical Science & Embalming

The abdominal evomo has made its way into our reading content. That stinks! For those of you who do not know what this is—the abdominal evomo refers to belly gas. First and foremost, if you haven’t read about what to do with an air pressure system, please refer back to our previous article.
For those that have read, let us get down to where it comes from and why it’s growing. The Clostridium Perfringens bacteria is present in approximately 80% of food poisoning deaths. Oddly enough, keeping food clean is a real challenge in our world, and when we age our body has a difficult time fighting things off. When we die from gas build-up or food poisoning, the death will mimic a heart attack. If there is a history of heart disease in the family (pretty much a guarantee, as “cardiopulmonary arrest” is the most commonly used immediate cause of death among physicians), there might be a doctor in the house willing to sign off that this death was heart related. However, do not be fooled. The presence of Clostridium generally goes hand-in-hand with fecal matter within our intestines. The bacteria is common enough that upon death, its presence will double every five minutes. Coincidentally, upon our death the body enters a state known as algor mortis, which refers to our temperature rising for a short time following death. Heat, as we know in chemical reactions, supplies energy and increases the number of reactions. In simple terms, if we heat fecal matter, we will produce more gas than if we left it alone. If you thought it wasn’t going to get worse, well, get ready. As the gas becomes trapped within the abdomen, forming a abdominal evomo, the air or gas compresses and pressurizes. Within our current understanding of chemistry, pressurized matter can reduce the energy needed for reaction. This can be best understood by the cold boiling process. To be put simply, if you pressurize fluid enough it can be brought to a boil without even becoming hot. As applied to our example, gas can be produced more and more rapidly every second.
As this process continues, the migration of this bacteria into the vascular system becomes more real. Once inside the vascular system, the bacteria will eat the sugar and fats, producing more and more gas and odor. Every step of the way, there will be a barrier of vapor lock left in its wake until it reaches the brain. If the bacteria arrives at the brain, we have a true case of embalmer’s nightmare. Due to the sugary and fatty tissue of the brain, the bacteria will produce large volumes of gas which will distort the facial tissue of the deceased, making it near impossible to restore. So with understanding this process and how it happens, it serves us well to remember to never allow the abdomen to rise higher than the chest. Read on for the rest.

Much like a UFO, specific cases yield many questions unanswered for embalmers. Furthermore, what we are able to detect with our eyes often still limits us from gathering all the details we need to do the best job. It was once said that an embalmer’s greatest disappointment or regret is never having the ability to get the same person twice. Hopefully as we grow together, we are able to keep good enough records and data to still advance and improve our capabilities.
While performing case analysis, it is essential that the embalmer is attentive to potential fluid or air obstruction which will prevent fluid traveling throughout the vascular system. Air obstructions might be regarded as the highest priority for the embalmer’s attention. Permitting the complete escape of air is the optimal result, however, we often can fall short of this expectation. Persistent channeling to release air may be necessary as the embalming process progresses. Often, a trocar is used to permit the escape of gas; however, this can often lead to just an intermittent release of gas. Following up the initial escape of gas with forceps or scissors can make an easier path for gas to travel through, despite what other obstructions may be present.
If air remains within the path of travel, fluid by nature has a very difficult time overcoming this obstruction. As fluid travels upstream against gravity without any air present, its ability to travel well is significantly impacted. When air is present in the vessel between fluid, a circumstance known as vapor lock occurs. This is great cause for concern, as truly there is no way to overcome this distribution issue without force, otherwise known as pressure. To even better understand this, know that air has the ability to compress, making it more and more challenging for a fluid to try to overcome it. We have already explained the negatives of a high internal pressure of the arterial system, so now we have the present problem of how we overcome vapor lock without also sacrificing the appearance of the deceased. We will cover the methodology that has been proven to overcome the embalmer’s nightmare, but you will have to keep reading. For now just remember, if its air, it stinks, so do what you can and let it loose!
