Embalming, in most modern cultures, is the art and science of temporarily preserving human remains to forestall decomposition and make it suitable for display at a funeral. The three goals of embalming are thus preservation, sanitization and presentation (or restoration) of a dead body to achieve this effect. Embalming has a very long and cross-cultural history, with many cultures giving the embalming processes a greater religious meaning. .
Embalming has been practiced in many cultures and is one of the earliest surgical procedures humanity undertook. In classical antiquity, perhaps the Old World culture that had developed embalming to the greatest extent was that of ancient Egypt, who developed the process of mummification. They believed that preservation of the mummy empowered the soul after death, which would return to the preserved corpse.
Other cultures that had developed embalming processes include the Incas and other cultures of Peru, whose climate also favoured a form of mummification.
Embalming in Europe had a much more sporadic existence. It was attempted from time to time, *[especially during the Crusades, when crusading noblemen wished to have their bodies preserved for burial closer to home. Embalming began to come back into practice in parallel with the anatomists of the Renaissance who needed to be able to preserve their specimens.
Contemporary embalming methods advanced markedly during the American Civil War, which once again involved many servicemen dying far from home, and their family wishing them returned for local burial. Dr. Thomas Holmes received a commission from the Army Medical Corps to embalm the corpses of dead Union officers to return to their families. Military authorities also permitted private embalmers to work in military-controlled areas. The passage of Abraham Lincoln's body home for burial was made possible by embalming and it brought the possibilities and potential of embalming to a wider public notice.
In 1867, the German chemist August Wilhelm von Hofmann discovered formaldehyde, whose preservative properties were soon discovered and which became the foundation for modern methods of embalming.
In the 19th and early 20th centuries arsenic was frequently used as an embalming fluid but has since been supplanted by other more effective and less toxic chemicals. There were questions about the possibility of arsenic from embalmed bodies later contaminating ground water supplies. There were also legal concerns as people suspected of murder by arsenic poisoning could claim that the levels of poison in the deceased's body were a result of embalming post mortem rather than evidence of homicide.
It is important to differentiate embalming from taxidermy. Embalming actually preserves the intact human body, while taxidermy is a recreation of an animal's form using only the creature's skin.
It is important to differentiate between a mortician and an embalmer. Any person who helps prepare the deceased for a funeral can be called a mortician whilst an embalmer is someone who has specifically been trained in the art and science of embalming. This commonly involves formal study in anatomy, thanatology, chemistry and specific embalming theory (to widely varying levels depending on the region of the world one lives in) combined with practical instruction in a mortuary with a resultant formal qualification granted after the passing of a final practical examination and acceptance into a recognized embalming body. Legal requirements over who can practice are extremely variable geographically but a common standard is to meet the above criteria or be a student, formal or otherwise, under the instruction of a qualified embalmer.
It is important to note that some regions and even countries have no specific requirements as to who may practice embalming. Additionally in many places in the world embalming is not done by trained embalmers but rather by doctors who, while they have the required anatomical knowledge, are not trained specialists in this field and their results are not always suitable for funeral viewing.
Embalming as practiced in the funeral homes of the Western World uses several steps. Modern embalming techniques are not the result of a single practitioner, but rather the accumulation of many decades, even centuries, of research, trial and error, and invention. A standardized version follows below, but variation on techniques is very common.
The first thing an embalmer should do is verify the identity of the deceased (normally via wrist or leg tags). At this point embalmers commonly perform basic tests for signs of death, noting things such as clouded-over corneas, lividity, and rigor mortis although in modern times people awakening on the preparation table is largely the province of horror fiction and urban myth. Any clothing on the corpse is removed and set aside; jewelry, also, is inventoried. A modesty cloth is sometimes placed over the genitals. Following this the corpse is washed in disinfecting and germicidal solutions and during this process the embalmer bends, flexes and massages the arms and legs to relieve rigor mortis. The eyes are closed and kept closed with an eye cap that keeps them shut and in the proper expression. The mouth may be closed via suturing with a needle and ligature, using an adhesive, wire or a needle injector, a specialized device most commonly utilized in North America and unique to mortuary practice. Care is taken to make the expression look as relaxed and natural as possible and ideally a recent photograph of the deceased while still living is used as a template. The process of closing the mouth, eyes, shaving, etc is collectively known as setting the features.
The actual embalming process usually involves four parts:
1. Arterial embalming, which involves the injection of embalming chemicals into the blood vessels, usually via the right common carotid artery. Blood is displaced from the right jugular vein. The embalming solution is injected through a mechanical pump and the embalmer massages the corpse to ensure a proper distribution of the embalming fluid. In case of poor circulation, other injection points are used.
2. Cavity embalming, the suction of the internal fluids of the corpse and the injection of embalming chemicals into body cavities, using an aspirator and trocar. The embalmer makes a small incision just above the navel 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 concentrated chemicals that contain formaldehyde. The incision is either sutured closed or a "trocar button" is screwed into place.
3. Hypodermic embalming, the injection of embalming chemicals under the skin as needed.
4. Surface embalming, which supplements the other methods,especially for visible, injured body parts.
Most good embalmings are completed in two or three hours, although an easy case may take less time and complicated cases can take days.
After the body is rewashed and dried, a moisturizing cream is applied to the face. The body will usually sit for as long as possible for observation by the embalmer. After being dressed for visitation/funeral services, cosmetics are applied to make it appear more lifelike and to create a "memory picture" for the deceased's friends and relatives. In the United States and Philippines baby powder or other deodorizers are sometimes used on the body for a pleasing fragrance. For babies who have died,the embalmer may apply a light cosmetic massage cream after embalming to provide a natural appearance; massage cream is also used on the lips to prevent them from dehydrating, and the infant's mouth is often left open a bit for a more natural expression. If possible, the funeral director uses a light, translucent cosmetic; sometimes, heavier, opaque cosmetics are used to hide bruises, cuts, or discolored areas. Makeup is applied to the lips to mimic their natural color. Sometimes a very pale or light pink lipstick is applied on males, while brighter colored lipstick is applied to females. Hair gels or hair spray is applied to style the hair, especially for deceased who are male. Mortuary cosmetizing is not done for the same reason as make-up for living people; rather, it is designed to add depth and dimension to a person's features that the lack of blood circulation has removed. Warm areas--where blood vessels in living people are superficial, such as the cheeks, chin, and knuckles--have subtle reds added to recreate this effect,while browns are added to the palpabrae (eyelids) to add depth, especially important as viewing in a casket creates an unusual perspective rarely seen in everyday life. During the viewing, pink-colored lighting is sometimes used near the body to lend a warmer tone to the deceased's complexion. A photograph of the dead person in good health is often sought in order to guide the embalmer's hand in restoring the corpse to a more lifelike appearance. Blemishes and discolorations (such as bruises, in which the discoloration is not in the circulatory system and cannot be removed by arterial injection) occasioned by the last illness, the settling of blood, or the embalming process itself are also dealt with at this time (although some embalmers utilize hypodermic bleaching agents, such as phenol based cauterants, during injection to lighten discoloration and allow for easier cosmetizing).
The foregoing describes the usual process for "cosmetic" embalming, wherein long-term preservation is not the goal; rather the natural appearance of the body is paramount.
As for clothing the body, tradition has been for the deceased to wear semi-formal clothing (a suit jacket and tie for men; a dress for women, commonly communion dresses, wedding dresses or bride's maid dresses and the less skin showing the better). In more recent years, the family often chooses to dress the decedent in more casual wear (such as a T-shirt and blue jeans), especially if the deceased was young. If a person is a member of the clergy of some religions, the person is often buried in religious vestments; as well, a member of the military, a police officer or firefighter is often dressed in his/her uniform. A military officer may also be dressed in a mess dress uniform that was never worn in life. Jewelry taken from the body prior to embalming is now returned if that is the family's wish.
As for undergarments, which are commonly chosen by the family or parents, panties and bras are generally simple and conservative but as with outer garments there are no requirements other than the next of kins' preferences, hopefully in accordance with the deceased's wishes. Depending on the height of the deceased, people are sometimes buried without their shoes on simply because shoes sometimes don't fit on swollen feet or will prevent the deceased fitting easily inside the coffin as feet often fail to sit perpendicular to the leg after death and can add several inches to a person's length lying down.
In many areas of Asia and Europe, the custom of dressing the body in a specially designed shroud, rather than in clothing used by the living, is preferred.
After the deceased has been dressed, they are placed in the casket (the term casket is derived from older usage to refer to a "jewel box", it is called a coffin when the container is anthropoid [a stretched hexagon] in form) for the various funeral rites. It is common for photographs, notes, cards and favorite personal items to be placed in the casket with the deceased. Even bulky and expensive items, such as electric guitars, are occasionally interred with a body. In some ways this mirrors the ancient practice of placing grave goods with a person for the afterlife. In traditional Chinese culture, paper substitutes of the goods are cremated with the deceased instead, as well as Hell Bank Notes specifically purchased for the occasion.
Embalming chemicals are a variety of preservatives, sanitising, and disinfectant agents and additives used in modern embalming to temporarily prevent decomposition and restore a natural appearance for viewing a body after death. A mixture of these chemicals is known as embalming fluid and is used to preserve deceased individuals, sometimes only until the funeral, other times indefinitely.
Typical embalming fluid contains a mixture of formaldehyde, methanol, ethanol, and other solvents. The formaldehyde content generally ranges from 5 to 29 percent and the ethanol content may range from 9 to 56 percent.
Decomposing bodies, trauma cases, frozen and drowned bodies, and those to be transported for long distances also require special treatment beyond that for the "normal" case. The recreation of bodies and features damaged by accident or disease is commonly called restorative art or demisurgery and is a sub-speciality inside embalming, although all qualified embalmers have some degree of training and practise in it. For such cases, the benefit of embalming is startlingly apparent. In contrast, though, many people have unreal expectation of what a dead body should look like due to seeing many "dead" bodies on television shows. Viewers unreasonably expect a body two weeks decomposed or having crashed in an airplane from 30,000 feet to look as it did in life. Ironically, the work of a skilled embalmer often results in the deceased appearing natural enough that the embalmer appears to have done nothing at all. Normally embalmers are very happy when parents can bring in a picture and make up if female to help make their loved one look just as if she was alive!
Embalming autopsy cases differs from standard embalming because the nature of the post mortem irrevocably disrupts the circulatory system with the removal of organs for examination. In these cases, a six-point injection is made through the two illiac or femoral arteries, subclavian or axillary vessels, and common carotids, with the viscera treated separately with cavity fluid or a special embalming powder in a viscera bag. In many morgues in the United States (such as the Los Angeles County Coroners Office) and New Zealand, these necessary vessels are carefully preserved during the autopsy; in countries in which embalming has been less common, such as Australia and Japan, they are routinely excised. This inhibits the type of embalming that families prefer and is a common source of conflict between government pathologists and embalmers.
Long-term preservation requires different techniques, such as using stronger preservative chemicals and multiple injection sites to ensure thorough saturation of body tissues.
It should be remembered that embalming is only meant to temporarily preserve the body of a deceased person. Regardless of whether embalming is performed, the type of burial or entombment, and the materials used — such as wood or metal caskets and vaults — the body of the deceased will eventually decompose. Modern embalming is done to delay decomposition so that funeral services may take place or for the purpose of shipping the remains to a distant place of disposition.
A rather different process is used for cadavers embalmed for dissection by medical and funeral service students. Here, the first priority is for long term preservation, not presentation. As such, medical embalmers use embalming fluids that are nearly pure formaldehyde (37–40%, known as formalin), made without dyes or perfumes. Many embalming chemical companies make specialized anatomical embalming fluids. Instead of using an embalming machine, anatomical embalmers may use gravity-feed embalming, where the container dispensing the embalming fluid is elevated above the body's level and fluid is slowly introduced over an extended time, sometimes as long as several days. Unlike funeral home embalming, no drainage occurs and the body distends with fluid that eventually reduces, leaving a normal appearance. There is no separate cavity treatment of the internal organs. Anatomically embalmed cadavers have a typically uniform grey colouration due both to the high formaldehyde concentration and to the lack of red colouration (added normally to standard, non-medical embalming fluids).
There is much difference of opinion amongst different faiths as to the permissibility of embalming. A brief overview of some of the larger faiths positions are examined below
Fictional works tend to portray the fantastic, extraordinary and often dysfunctional aspects of any profession or activity with which the public has little contact, and to ignore the mundane or routine. Embalming is no exception.
