→ 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.
