1. Arterial embalming:
It involves the injection of embalming chemicals into the blood vessels, usually via the right common carotid artery. Blood and interstitial fluids are displaced by this injection and, along with excess arterial solution, are expelled from the right jugular vein and collectively referred to as drainage. The embalming solution is injected with a centrifugal pump and the embalmer massages the body to break up circulatory clots as to ensure the proper distribution of the embalming fluid. This process of raising vessels with injection and drainage from a solitary location is known as a single-point injection.
In cases of poor circulation of the arterial solution additional injection points (commonly the axillary, brachial or femoral arteries, with the ulnar, radial and tibial vessels if necessary) are used. The corresponding veins are commonly also raised and utilized for the purpose of drainage. Cases where more than one vessel is raised are referred to as multiple-point injection
2. Cavity embalming:
It refers to the replacement of internal fluids inside body cavities with embalming chemicals via the use of an aspirator and trocar. The embalmer makes a small incision just above the umbilicus (two inches superior and two inches to the right) and pushes the trocar in the chest and stomach cavities to puncture the hollow organs and aspirate their contents. He then fills the cavities with embalming fluid. The incision is either sutured closed or a "trocar button" is secured into place.
3. Hypodermic embalming:
It is a supplemental method which refers to the injection of embalming chemicals into tissue with a hypodermic needle and syringe, which is generally used as needed on a case by case basis to treat areas where arterial fluid has not been successfully distributed during the main arterial injection.
4. Surface embalming:
Another supplemental method, utilises embalming chemical to preserve and restore areas directly on the skin's surface and other superficial areas as well as areas of damage such as from accident, decomposition, cancerous growth or skin donation.
