→ Diffusion- Chemical Science & Embalming

To be up front, do NOT consider this to be the greatest source of information about chemistry.  In fact, failing in a chemistry class among students a couple years older than I was the beginning of my chemistry education.  Let this instead be the most practical explanation of "diffusion" and why it matters to embalmers.

Diffusion, at a basic understanding, can be described as a process where molecules are evenly dispersed over time. This transport will happen from an area of high concentration to low concentration. Gravity and edema is a fitting example any embalmer can understand. Consider gravity and its affect on water retained in the body. In this example we can expect fluid to be retained in the legs.  Logically the greatest volume or concentration of fluid would be at the lowest parts of the legs. If we would elevate the legs into the air, fluid would move from a high concentration area to a lower concentration area.  To be more specific, fluid would move from the legs towards the abdomen. In science we describe this process as diffusion.

There are many factors which can influence diffusion.  Understanding these factors assists the embalmer to apply the most effective techniques.  For instance, temperature is a way to influence diffusion.  It is also a reason many experts suggest using warm water within the fluid solution. On the micro level, molecules when cold move the slowest, while molecules hot move the fastest. The movement or lack there of aides and inhibits the transport of molecules which occurs during the diffusion process. This is part of the challenge which many embalmers face during extreme refrigerated cases.

Several other factors contribute to our complete understanding of diffusion. Permeability of cell walls can be drastically affected by polar ions such as calcium, chloride or salts.  Talking permeability, smaller molecules will have an easier time passing as compared to larger molecules. Also, thicker walls are harder to pass while thinner walls are easier to pass. Considering all of this, we wouldn't be able to pass anything without force.  We measure force as pressure. Pressure is a quantitative measurement of force which can be taken at any site or location. As in our example, legs elevated, we are using gravity to generate negative pressure in the low fluid concentration area ( abdomen ) and generate positive pressure in the high fluid concentration area ( legs ). Similarly under injection we are using the pump motor to force fluid and generate postive pressure against the vascular wall. As the pressure increases, the speed at which fluid ( high concentration ) diffuses into the low concentration areas ( the tissues ) increases.

Do you agree having covered temperature, pressure and permeability as it relates to diffusion benefits embalmers? In my opinion, the preservation of not only the deceased but also the art and science of embalming depends on it. Diffusion is what embalmers today count on to saturate and restore tissue for viewing purposes.

→ Embalming Methodology- Old School

For our purposes we are calling this embalming technique, "Old School".  For those embalmers who know it, the name is out of respect for those still using it.  With respect for the the veterans of the profession, some young embalmers have learned why this old trick should never be forgotten.

The method is simple really, this is one of my personal favorites for apparent difficult cases (cases you'd expect to raise more than one vessel). Make a selection of an artery.  Be sure NOT to rupture any vessels in the process. If one should break, take care to use a locking forcep to restrict drainage. Incise the artery and insert a cannula, my preference is to utilize a Director Cannula to obtain access to the aorta.  This is helpful to reduce the possibility of post embalming swelling.

Estimate the deceased total body weight and take note.  Begin to inject without drainage the total body weight in ounces (you most likely will not need to inject the entire solution). For this method to work well, your pressure setting must be high (at least greater than 20) and it is wise to heavily restrict your rate of flow (trickle treat folks).  Take notice of the superficial vessels as an indication of fluid distribution.  Continue injection so long as swelling does not occur and until adequate firmness is achieved.  Massage during and after injection and apply warm water over the deceased (this accelerates the firming effects, heat provides ATP for the RXN).  Adequate and thorough aspiration following injection is very important as this will serve as the only means to remove blood from the body.

For best results consider handling these cases with a higher index solution or even waterless. For waterless cases, consider using the Pressure Pump Injector. This hand pump permits high pressure injection with ease-one bottle at a time-with trigger control.

This high pressure style embalming method we call "Old School" more than makes up for its distribution limitations with exceptional diffusion (high to low-low to high concentration). Embalming text supports heavily drainage being overated, we won't agree entirely.  We acknowledge the importance of drainage to achieve a lifelike appearance.  With that being said "Old School" remains as a tried and tested approach every embalmer can count on.

→ Waterless Embalming- Theory & Practical Application

Theory

Practical Applications Include: Decomposition / Edema / Trauma or Restoration Cases
Within the bounds of our topic, I must share the words of a great mentor who often said-
“ An embalmers ability is not well demonstrated or established with cases with little difficulty- it can be quantifiably measured by the progress made in times of trial and failure. ”
When or how might an embalmer make the determination to go waterless? The first step would be to judge not simply the case at hand, but also yourself. To be true and honest with the skills you possess is necessary to understand the limitations of your own capabilities. Second, how compromised is the case you are called to serve? A very clear indicator for me, as an embalmer, is the signs of marbling. Marbling is the apparent darkened discoloration of the superficial venous system. With this condition, one can reasonably expect the venous system in its decomposed state to have changed. Expect the expected- weaker vessel strength and decreased ability, or complete loss of the ability, to return blood or fluid (drainage).
Signs of decomposition should not be the only qualifier. For our purposes, we might also add cases of edema or restoration-that require rapid firmness. If we compare our most straightforward embalming cases with our more difficult cases, what can we learn? Would we agree that most straightforward cases required a lower chemical concentration and had significantly greater distribution to vessels as compared to the difficult cases. Having developed a case intuition or case analysis skill, the embalmer is provided the opportunity to adjust their method. Based upon the results presented- is it not reasonable to believe there might be a correlation between distribution and chemical concentration? If we accept these results and are honest with our limitations, we can grow. For as Jake Huard said, “To achieve we must believe”. If we continue to develop this belief, we might suggest that an increased chemical concentration can do well to compensate for poor distribution. When employed properly, results will show that this is true. Mastery of this skill requires a broad knowledge of the various difficult cases.
Edema is known to challenge even skilled embalmers. It is well known by expert embalmers, to adjust their fluid concentration to account for the added water. By estimating the volume of retained fluid- embalmers deduct this value from the water added to their fluid mixture. While the higher concentration of fluid enters the tissue- chemical concentration decreases. Though the concept is fairly straightforward, this is truly an art as much as a science.
In closing, trauma may be one of the greatest challenges an embalmer can face. Repairing tissue without first preservation could fail even the most skilled restorative artists. By experiencing the challenge of restoring poorly preserved tissue, restorative artists can learn to advantage their work with greater preservation.
