1st Quarter Embalming Supernotes Lecture 1 ORIGIN OF EMBALMING “Balsamon”- dried or granulated resin (Greek); refers to the practice of filling the body cavities with resin to preserve it MODERN EMBALMING Embalming is the art and science of disinfecting, temporarily preserving, and restoring to a normal appearance of a dead body Art: skilled workmanship requiring brain/eye/hand coordination Science: any knowledge dealing with a body of known facts about the universe, facts are systematically arranged, show the operation of general laws Based on the laws of physics, chemistry, and anatomy Effects of Embalming Disinfection: destruction or inhibition of pathogenic bacteria and their products in or on the body Temporary preservation: the chemical treatment of the body to delay the decomposition for a limited amount of time, changes body chemicals to become resistant to agents of decomposition, time is variable: depends on the condition of the body, skill of the embalmer, strength of chemicals; only for the duration of the funeral Restoration: care of the deceased to recreate natural form and color for the comfort of the family EMBALMING TYPES Vascular/arterial embalming: uses the vascular system to achieve embalming goals, injection of preservative solution into major arteries and drainage of blood from main veins Cavity embalming: direct treatment other than by arterial embalming of the contents of the body cavities, lumina of the hollow viscera, achieved by aspiration Hypodermic embalming: injection of embalming chemicals directly into tissues via needle and syringe or a trocar Surface (topical) embalming: direct contact of internal or external body surfaces or tissues with embalming chemicals EMBALMING PROCESS Arterial: wash and disinfect surface of body, close mouth and eyes, suitable amount of embalming fluid is injected through major artery, vein is raised and opened to drain blood, vessels are ligated and incisions stitched up Cavity: use trocar with suction to remove gas/blood/food/etc… by puncturing each organ, use preservative fluid and inject it into each organ, puncture points are closed Hypodermic: uses hypodermic needle and syringe or a small trocar with the embalming machine to inject preservative directly into tissue Topical/Surface: uses cotton soaked in fluid and placed directly on surface of body HOW AND WHY EMBALMING WORKS Decomposition Bacteria in intestines move into other parts of the body and use enzymes to separate amino acids in proteins, so bacteria digest the molecules that make up the human body Enzymes already in cells break down the rest of the cell (autolysis) Can be slowed down by introducing preservatives Preservatives Blocks protein receptors, blocks enzymes, kills bacteria, must be able to get to proteins (fluid diffusion), can temporarily prevent decomposition but can’t undo damage already done Why embalm? Provides time to bereaved to plan funeral services, allows for viewing, repairs some damage to the body so mourners can see their loved ones at peace, allows transportation of the body, compassion and consideration of family and human dignity and family solidarity DUTIES AND RESPONSIBILITIES OF THE EMBALMER Fiducial Relationship: relationship between family and embalmer, trust-based, treat human remains with the same love and respect as the family does Care-Giving Profession: serve those at the most sensitive time in their lives with expertise, sympathy and understanding Protect and maintain the dignity of human remains Disinfect, preserve, and restore the dead with reverence and efficiency so the health of the public remains free of disease Aid and comfort the bereaved whenever possible Perform duties in a quiet, dignified, and professional manner with the greatest care and diligence with maximum efficiency Keep informed on new products, techniques, and law; also keep an open mind Lecture 2 DEATH PROFESSIONAL IMPORTANCE OF DEATH Definition: death is the process by which the chemical and physical changes start to happen (within the body) Embalming puts a temporary halt to these changes DEFINING DEATH Thanatology: the study of death and all its aspects Medical definition: the cessation of total brain function Legal definition: differs by state, IL goes with the medical definition Other definitions Long: death is the cessation or extinction of life manifested by the absence of heartbeat and respiration and characterized by the absence of metabolism and the total lack of irritability. It is the cessation of all vital functions without the capability of resuscitation. Short: Death is the irreversible cessation of all body functions TERMS ASSOCIATED WITH DEATH Apparent death: a condition in which the heartbeat, respiration, body warmth, and other manifestations of life are very feebly maintained Death rattle: sound sometimes made by the dying caused by labored breathing through air passages partly filled with mucus Death struggle: semi-convulsive series of movements and facial twitches which may occur before death Agonal period/state: that period of time immediately before death, length and severity can vary Moribund: a person in the agonal state In Articulo Mortis: at the point of death Human remains: the body of a deceased person, includes skeletal remains and bodies in any stage of decomposition Cadaver: a dead body embalmed in a special manner for purposes in anatomical dissection Cremated remains: those elements of a dead human body that remain after cremation Corpse: legal term for a dead human body, DO NOT use in the profession Mortality rate: ratio of the number of deaths over a given period of time to the population of a given area Morbidity rate: ratio of the number of specific diseases over a given period of time to the population of a given area TYPES OF DEATH Somatic Death: the death of the whole organism, cooperation between bodily systems breaks down 2 stages: Clinical and Biological Clinical: characterized by cessation of heartbeat and respiration, aka legal death, brain is still alive, can last 5-6 minutes before biological death occurs Biological: “irreversible death”, irreversible cessation of total brain function Modes of Somatic Death: failure of 1 or more of the 3major organs that belong to the “tripod of life” aka the heart, lungs, and brain; coined by Bichat! Syncope: death beginning at the heart Coma: death beginning at the brain Asphyxia: death beginning at the lungs Cellular Death: death of individual cells of the body, always follows somatic death Muscle cells may live another 3-7 hours; red blood cells and cells in the cornea (6 hrs) Cause of cellular death: lack of oxygen called anoxia; (hypoxia is the slow loss of oxygen) Other kinds of cellular death (during life) Necrobiosis: the antimortem death of cells and their replacement by new cells of the same type Necrosis: pathological death of cells in a still-living body, examples include gangrene and decubitus ulcers (bed sores) Factors influencing onset and duration of postmortem cellular death Cause of death (sudden = onset slow, duration long; exhausting diseases = onset quick, duration short) Condition of body (young = slow, long; old = quick, short; obese = quick, long; thin = slow, short) Environmental conditions (cold = slow, long; hot = quick, short) Use of medications before death (cytotoxic = quick, short; healthier medications = slow, long) Lecture 3 SIGNS OF DEATH: those sensible manifestations that indicate the absence of life in the human body, the only single reliable sign is decomposition Cessation of heartbeat and respiration: cannot be taken as conclusive, IL state law says the absence of both for 5 minutes is presumptive death Algor mortis: coolness, the postmortem adjustment of body temperature to that of the environment Rigor mortis: stiffness, cadaveric rigidity, temporary stiffening of voluntary and involuntary muscles due to chemical changes Livor mortis: lividity, postmortem settling of the blood to the dependent parts of the body Dehydration: loss of moisture from body tissues, shrinkage and petrification (dessication) possible in extreme cases Changes in the eye: dehydration causes visible changes in the appearance and shape of the eye like loss of shine, clouding of the cornea, and the eye begins to sink Decomposition: generally the last sign to appear, 5 signs of decomposition (green patch over lower right quadrant, abdominal swelling, odor, purging, and skin slip) TESTS FOR DEATH: any procedure used to prove a sign of death Expert: medical instruments are necessary to perform Stethoscope test: checking for heartbeat and respiration Opthalomoscope test: checking for a reaction in the eye to light stimulus Dye injection test: if dye does not appear in the white of the eye then death has occurred Electrocardiograph test: aka EKG, no reading indicates death Electroencephalograph test: aka EEG, measures brain activity, no auditory brain stem response (ABR) indicates death Inexpert Heartbeat and respiration test Pulse test Ligature test: tie string around finger, swelling indicates the subject is still alive Ammonia injection test: if the skin turns red indicates the subject is still alive THE ANTEMORTEM/AGONAL CHANGES General considerations Agonal periods are much longer now Embalming considerations The longer the agonal period, the longer the disease has to change the body chemistry Secondary infections can develop and change body chemistry further More body changes take place as time goes on Long-term drug treatments also change body chemistry Types of Agonal Changes Thermal Agonal Algor: lowering of body temperature Agonal fever: rising of body temperature, usually caused by febrile diseases Circulatory Agonal hypostasis: pull of gravity on blood Agonal coagulation: clotting Agonal capillary expansion: capillaries widen to compensate for poor blood circulation, cause elevated moisture content which may lead to edema Moisture changes Agonal edema: swelling causes moisture levels to rise Agonal dehydration: reduced ability to absorb water Agonal translocation of bacteria: aka agonal invasion/bacterial migration: migration of bacteria to other parts of the body other than the stomach Facies hippocratica: changes in facial appearance that hint at death Loss of natural reddening of skin/paleness, eyes sink, eyelids darken, nose shrinks, mucous membranes dry and sink, lower jaw lengthens, lines and creases get deeper, loss of muscle tone Lecture 4 POSTMORTEM CHANGES DEFINTION AND IMPORTANCE Those changes in the body from the molecular to the systemic level that take place after biological death The longer the postmortem interval (between biological death and embalming) the more changes will appear and the more severe/noticeable they are Changes can interact with each other Number of changes and their progress will influence the chemicals and the technique required to embalm; after a certain point embalming is not possible Physical Changes: a change in the location of physical state of a body chemical, chemical identity of the body stays the same Algor Mortis Livor mortis Dehydration Change in the viscosity of blood Chemical Changes: change in the identity of the chemicals or chemicals get broken down Decomposition Rigor mortis Change in blood pH Postmortem stain Postmortem caloricity Hydrolysis PHYSICAL CHANGES ALGOR MORTIS: the postmortem adjustment of the body temperature to that of the surrounding medium Metabolism – total biochemical reactions, regulated by the body to maintain temp. Body can remove heat by respiration, convection, radiation, elimination, and perspiration but after death only direct convection still works to release heat Postmortem thermal changes Postmortem caloricity: the temporary rise in temperature just after somatic death because cells still function Agonal Algor: cells reduce their heat output during the agonal period (antimortem) Variation: when medium is warmer than the body, it causes dehydration and accelerated clotting, rapid cooling is the best temperature change for embalming Rate of Heat Loss Internal organs cool slower than skeletal tissues Body loses more heat right after death then the rate slows Average rate: 4 degrees F for the first 3-4 hours, then 1.5 degrees F until the medium temperature is reached Factors that influence heat loss Size of body (tall cools slower) Body weight (fat cools slower) Age at death (very young and very old cool faster) Cause of death (febrile disease = slow, TB or other disease = fast, healthy sudden death = slow, loss of blood = fast) Clothing (slows onset and rate) Environmental temperature and humidity (closer to 98.6 = slow, rate is fastest when temperature is low and humidity is low, moving air will also speed up cooling) LIVOR MORTIS: aka postmortem lividity, cadaveric ecchymosis, cadaveric lividity, passive congestion, or hypostatic congestion; it is the postmortem reddish/blue discoloration of the body due to hypostasis of the blood, hypostasis is the postmortem gravitation/settling of the blood into all dependent areas not pressed upon Postmortem blood movements Capillaries collapse, blood goes to the deeper tissues, changes the skin color, blood follows gravity to dependent parts (hypostasis(, weight of blood enlarges dependent surface capillaries and changes the color from pink to reddish blue to blue/purple (610 hours after death) Effect of contact pressure Shows on neck, curve of back, sides, and parts of the backs of legs, wouldn’t see it on parts actually pressed to the surface (in supine position) Variations: patterns depend on the position one dies in Embalming considerations Injection should be able to flush out the blood as long as it still remains intravascular, if it becomes extravascular then it won’t be able to be flushed out DEHYDRATION: the loss of moisture from the body Never stops but can rehydrate with arterial injection but will start to dehydrate again right away Dessication: extreme dehydration, starts on toes, fingers, etc. gets black and hard, cannot be rehydrated Mummification: extreme, rapid, and complete desiccation Lecture 5 Conditions accelerating dehydration Refrigeration Hypostasis of blood and other bodily fluid: non-dependent parts are drier Air currents Agonal dehydration Post-Embalming Dehydration Increase in blood viscosity: increase in the degree of thickness of the blood (plasma startsz to dry, blood becomes thicker, tendency to form more clots The closer to body temperature, the more viscosity will appear and quicker Put in refrigeration, temporarily decreases viscosity (hypinosis) but the rapid dehydration Types of Postmortem Coagulation Cruror clot – “red currant jelly”, soft clot, forms quickly, includes both plasma and solid, dark red, easy to remove “Chicken Fat Clot” – forms later, white blood cells separate from red cells, yellowish/grayish white, stickier but still removable White fibrin clot – very sticky and solid, clot of fibrin, usually found in right atrium of heart, takes longer to develop, can establish 2 sites of drainage to alleviate CHEMICAL CHANGES DECOMPOSITION: the chemical breakdown of complex molecules into simpler molecules, cause by enzymes, end products = the simplest molecules left at the end Types of Decomposition Proteolysis: the breakdown of proteins Proteins > amino acids > amines, CO2, and H2O > amines break down into putresine, cadaverine, indole, and skatole > end products (ammonia and ammonic compounds, H2 gas, hydrogen sulfide, hydrogen phosphide, N2 gas, CO2, H2O, methane, phosphoric acid, sulfuric acid and mercaptans (-SH radical) Causes embalming complications because ammonia neutralizes formaldehyde Putrefaction: breakdown of proteins by anaerobic bacteria’s enzymes, end products have foul odors, most common Decay: cause by enzymes produced by aerobic bacteria, endproducts not foulsmelling Sacchrolysis: decomposition of sugars in the body in the form of glycogen or glucose Broken down by anaerobic bacteria in carbohydrates (fermentation) Carbohydrates > organic acids > H2O and CO2 Lypolysis: breakdown of body fat (triglycerides/lipids/adipose) performed by lipases Broken down into fatty acids and glycerol Under certain circumstances, a chemical transformation can take place when the body is buried in direct contact with moist alkaline eart, the tissue transforms into adipocere (“grave wax”), a soft, whitish gray/yellow material, that is crumbly, greasy, and cheese-like, has a sweet/rancid smell and doesn’t decompose further, takes 3-6 months to form; this is called *saponification* Autolysis: the self-destruction of cells Lysosome’s membrane is broken down by acids because the pH of the body shifted and digestive enzymes are dumped out and break down the proteins fo the cell Signs of Decomposition Color: green discoloration of the skin, starting at lower right quadrant Odor: as putrefaction begins Purge: leaking through the openings of the body Skin slip/Desquamation: separation of epidermis from dermis: the rete mucosum breaks down Gas collection: in body cavities and eventually in the tissues themselves Lecture 6 FACTORS INFLUENCING THE RATE OF DECOMPOSITION 1. Intrinsic factors Age at death: (stillborn infants = slow, infant that has breathed and been feed (fast), old = dryness of tissues slows decomposition somewhat) Gender: (women tend to be faster because they retain more moisture, also certain diseases that only women get that contribute to death hastens decomposition, like toxic shock syndrome Corpulence: body fat; obese = fast, thin = slow Cause of death: infection = fast, agonal dehydration = slow, dismemberment (fast in trunk and slow in dismembered part), arsenic poisoning = slow Bacteria: an elevation of bacteria present in the body at death increases decomposition Moisture level: dehydrate = slow, edema = fast Thermal conditions: cooler = slow, hotter = fast Drugs/Therapeutic Agents: cytotoxic = fast 2. Extrinsic factors Access to air: fast because of airborne bacteria, aerobic bacteria cause decay Atmospheric Moisture level: humid = rapid because it keeps heat in the body, dry = slow Temperature of the environment (air) – ****optimum bacteria temperature is 99.5 degrees F****, hotter = up to 120 degrees then stops, colder = slows until 50 degrees, then slows significantly until 32 degrees at which point growth stops Introduction of bacteria from the atmosphere (fast) Pressure of earth or clothing (slow) THE ORDER OF DECOMPOSITION OF THE ORGANS 1. Lining of the larynx and the trachea* 2. The infantile brain 3. Stomach 4. Intestines 5. Spleen 6. Mesentery & Omentum (connective tissue that holds the organs together and the linings of the organs) 7. Liver 8. Adult brain 9. Heart 10. Lungs 11. Kidneys 12. Urinary bladder 13. Esophagus 14. Pancreas 15. Diaphragm 16. Blood vessels* 17. Non-pregnant uterus* ORDER OF DECOMPOSITION FOR BODY TISSUES 1. Blood and lymphatic 2. Soft tissues: parenchyma of the organs 3. Firm tissues: stroma of the organs (connective tissue/structural) and muscles 4. Hard tissues: cartilage and bones and teeth ORDER OF DECOMPOSITION FOR BODY COMPOUNDS 1. Carbohydrates 2. Proteins 3. Fats 4. Firm proteins: chemical bonds are stronger, in connective tissue like ligaments, cartilage, and tendons 5. Calcium compounds: bones and tooth enamel CASPAR’S LAW The same degree of decomposition is found in a body exposed in air for 1 week as a body that was in water for 2 weeks and a body buried in earth for 8 weeks 1:2:8 DECOMPOSITION IN WATER Takes twice as long for a body to decompose than in air, floats face down, decomposition starts in face and neck first, body will the sink, after decomposition starts gas collection will eventually cause the body to rise again 4 factors that affect decomposition in water Temperature of the water (warm water = faster decomposition) Nature of the medium: what kind of water, salt water = slow, fresh = faster, decaying matter present in the water – faster Lecture 7 CHANGE IN BODY PH Mechanism: scale from 0 (acidic) to 14 (alkaline/basic) Body during life is about 7.4 Just after death it turns acidic (almost 5.5) for about 3-4 hours and then increasingly alkaline again Embalming consequences Quickens rigor mortis Formaldehyde does not embalm with acidic fluid well, must add buffers to arterial fluid to control pH Use higher concentration of formaldehyde RIGOR MORTIS: aka cadaveric rigidity, postmortem stiffening of body muscles, voluntary and involuntary, by natural body processes; most variable of postmortem changes 3 stages of postmortem muscle condition 1. Primary flaccidity: all muscles relax immediately after somatic death, may be spasms as individual muscle cells die 2. Onset, duration, and termination of rigor mortis: all muscles contract after cellular death 3. Secondary flaccidity: all muscles relax permanently It is possible to relieve rigor by massaging 2 cases in which rigor will not occur Bodies that are burned or scalded Bodies that are embalmed before onset of rigor Times of appearance and disappearance Usually onset occurs in 8-20 hours, peaks after 12 hours of onset and may last anywhere from 10-72 hours after onset The later onset occurs, the longer it takes for rigor to disappear and it is more severe Visible signs of rigor Cutis anserina: goosebumps, caused by arrector pili muscles (muscles around hair follicles) contracting Cause of Rigor: decomposition of ATP in the muscles Factors affecting rigor Body and/or Environmental Temperature: hot = fast, cold = slow, 98-100 degrees F is the optimum temperature, up to and stopping at 120 degrees and down to 32 degrees Age: old and infants = rapid and short; young adults = severe Cause of death: sudden and extreme muscular activity before death and poisoning = rapid, intense, and short Muscle Condition and Development: greater development and strength = slow onset, long duration, and intense Order of Appearance and Disappearance 1. Eyes and eyelids 2. Back of neck 3. Lower jaw 4. Facial muscles 5. Front of neck 6. Chest 7. Upper extremities 8. Abdomen 9. Lower extremities Disappears in the same order Conditions Mistaken for Rigor Heat stiffening: permanent coagulation and stiffening of tissues when exposed to high heat (above 120 degrees F), chemical change Cold stiffening: 40 degrees F or below, body fats solidify, can cause skin slip if heated too quickly, physical change Lecture 8 Catalepsy: rare, muscular rigidity due to psychological or nervous disorders, seems to be in a death-like coma, aka hysterical paralysis Cadaveric spasm: last act of life is crystallized in death, in traumatic or accidental deaths or great psychological or physical strain at time of death, example: suicides, traffic accidents, violence; aka spontaneous rigor Embalming difficulties of rigor pH of the body is at its most acidic during rigor, after rigor passes, bacterial activity increases dramatically and requires a stronger solution during embalming to be effective rigor restricts fluid distribution, walls of the arteries constrict which causes less fluid diffusion rigor reduces the formaldehyde effectiveness distorts the appearance of the body, difficult to pose body Recommendations: make judgment on stiffness of muscles and massage, continue to massage as injection occurs to help move the fluid, massage the hands and feet first POSTMORTEM STAIN: an extravascular blood discoloration due to hemolysis Hemolysis: decomposition of red blood cells Mechanism: gravity causes blood to separate into plasma and cellular components, this is known as plasma filtration; releases hematin about 6-10 hours after death into the plasma which seeps through the capillary walls and between the cells 3 results Body tissues have more moisture = postmortem edema Solid material left in capillary gets harder/thicker/stickier and can block up capillaries Permanent bruise-like staining from the hematin outside the capillaries Differences between livor mortis and postmortem stain Livor mortis is a physical change, PM stain is a chemical changes Livor mortis is intravascular, PM stain is extravascular Livor mortis is reversible, PM stain is permanent Embalming implications: need to embalm ASAP POSTMORTEM CALORICITY: aka postmortem fever, the rise in body temperature after somatic death Mechanism: heat is retained in the tissues, metabolism continues until cellular death, body’s mechanisms of losing heat doesn’t work anymore, can reach almost 110 degrees F Conditions affecting degree of caloricity Increased: febrile diseases; systemic bacterial infections; increased muscular activity at TOD; interruption of heat regulating mechanisms of the body; sudden death Decreased: debilitating diseases, agonal Algor Embalming implications Quickens rigor mortis and makes it more severe Quickens decomposition Earlier dehydration, more clotting HYDROLYSIS: breakdown of complex substances into simpler ones and one of the catalysts is water or the elements of water Imbibition: the absorption of water by any substance (edema) Antimortem edema: abnormal increase in the moisture content of the body before death Common in congestive heart failure and renal failure Postmortem edema: seeping of blood plasma extravascularly into tissues Encourages decomposition and skin slip Maceration: decomposition of a body in water, water moves from the outside in Tissues get soft, water-filled blisters appear on skin, muscles detach from bones and skin slip may occur if left in the water long enough Lecture 9 THE PURPOSES OF EMBALMING 1.
