How long does it take for the results of a post-mortem?
Obtaining a copy of the post-mortem examination report – If the cause of death is ascertained at the time of the post-mortem examination the Pathologist will tell us their findings immediately but their full written report is not usually available until 6 weeks after the examination.
If the cause of death is not immediately ascertained and histology and/or toxicology samples have been retained for further analysis we would again expect the report within 6 -12 weeks of the post-mortem examination unless there has been a specialist examination. The Coroner is content to share a copy of the pathologist’s post-mortem examination report with the next of kin or other “interested persons”.
Please let us know if you would like to receive the full report. Do bear in mind that the report contains detailed and explicit medical information and many people find this unpleasant reading. The Coroner’s Officer will provide an overview of the content of the Pathologist’s report but they are not medically trained and so detailed explanations of post-mortem examination findings may be better addressed by your GP.
How long is a post-mortem after death?
What happens during a post-mortem – A post-mortem will be carried out as soon as possible, usually within 2 to 3 working days of a person’s death. In some cases, it may be possible for it to take place within 24 hours. Depending upon when the examination is due to take place, you may be able to see the body before the post-mortem is carried out.
The post-mortem takes place in an examination room that looks similar to an operating theatre. The examination room will be licensed and inspected by the HTA. During the procedure, the deceased person’s body is opened and the organs removed for examination. A diagnosis can sometimes be made by looking at the organs.
Some organs need to be examined in close detail during a post-mortem. These investigations can take several weeks to complete. The pathologist will return the organs to the body after the post-mortem has been completed. If you wish, you’ll usually be able to view the body after the examination.
Can post-mortem tell exact time of death?
Determining Time of Death Defining Time of Death There are several times of death. Let me repeat that—there are several times of death. Time of death seems to be a simple and straightforward term that obviously means the exact time that the victim drew his last breath. Unfortunately, it’s not quite that simple. There are actually three different times of death:
- The physiologic time of death, when the victim’s vital functions actually ceased.
- The legal time of death, the time recorded on the death certificate.
- The estimated time of death, the time the medical examiner estimates that death occurred.
It is important to note that the estimated time of death can vary greatly from the legal time of death and the physiologic time of death. The only absolutely accurate determination of the time of death is the uncommon circumstance in which a person died with a physician or other skilled medical professional present.
- The doctor could make the determination and mark the time, and even this is assuming his watch or the clock on the wall was accurate.
- But that little inaccuracy aside, a death witnessed in this fashion is the only time that the three above times of death would correlate with one another.
- Otherwise, it is impossible to determine the exact time of death.
But what if someone witnessed the fatal blow or gunshot or what if the event was recorded on a timed surveillance camera, wouldn’t that accurately mark the time of death? The answer is a qualified yes. If the witnessed event led to immediate death, then the witness would have seen the actual death.
If not, the witnessed event is simply the trauma that led to death but not the actual moment of death. People can survive massive and apparently lethal injuries for hours, even days or years. But most deaths are not witnessed. Natural death may come during sleep, and accidental and suicidal deaths often occur when the victim is alone.
In homicides, the perpetrator is typically the only witness and he rarely checks his watch, and even if he did, he’s not likely to talk about it. This means that when the medical examiner must determine the time of death he can only estimate the approximate time.
- These times of death may differ by days, weeks, even months, if the body is not found until well after physiologic death has occurred.
- For example, if a serial killer killed a victim in July, but the body was not discovered until October, the physiologic death took place in July, but the legal death is marked as October, since that is when the corpse was discovered and the death was legally noted.
The medical examiner estimated that the time of death could be July, or it could be June or August. It is only an estimate and many factors can conspire to confuse this determination. But, it is critically important for the medical examiner to be as accurate as possible.
The Importance of the Time of Death An accurate estimation of the time of death can lead to discovering the identity of the assailant. In criminal cases, it can eliminate some suspects while focusing attention on others. For example, a husband says that he left for a business meeting at 2 P.M. and returned at 8 P.M.
to find his wife dead. He says that he was home all morning and that she was alive and well when he left. If the ME determines the time of death was between 10 A.M. and noon, the husband has a great deal of explaining to do. On the other hand, if the estimation reveals that the death occurred between 4 and 6 P.M., and the husband has a reliable alibi for that time period, the investigation will move in a different direction.
- Notice that in the above example the ME gave a range rather than an exact time for his estimated time of death.
- He didn’t say 4:30 P.M.
- But rather said between 4 and 6 P.M.
- Simply put, that’s the best he can do and that’s why it’s called the estimated time of death.
- It’s a best guess.
- The time of death is not confined to criminal investigations; it can also come into play in civil situations.
Insurance payments may depend upon whether the insured individual were alive at the time the policy went into effect or if he died before the policy expired. Even a single day can be important. Likewise, property inheritance can hinge on when the deceased actually died.
Suppose two business partners die near the same time. Their contract may read that the company assets go the survivor if one of them dies. In this case, the heirs of the one that died last would own the company assets. Similarly, the dispersal of property under a will might be affected by which partner died first.
Determination of the Time of Death Determining the time of death is both an art and a science and requires that the medical examiner use several techniques and observations to make his estimate. As a general rule, the sooner after death the body is examined, the more accurate this estimate will be.
- Unfortunately, the changes that a body undergoes after death occur in widely variable ways and with unpredictable time frames.
- There is no single factor that will accurately indicate the time of physiological death.
- It is always a best guess.
- But when the principles are properly applied, the medical examiner can often estimate the physiologic time of death with some degree of accuracy.
To help with his estimation, the ME / Coroner utilizes various observations and tests, including:
- Body temperature Rigor mortis Livor mortis (lividity) Degree of putrefaction Stomach contents Corneal cloudiness Vitreous potassium level Insect activity
- Scene markers
The most important and most commonly used of these are body temperature, rigor mortis, and lividity. French physician Dr. Alexandre Lacassagne (1843–1924), director of Legal Medicine in Lyon, France, wrote extensively on algor mortis (the temperature of death), rigor mortis (the stiffness of death), and livor mortis (the color of death).
- Body Temperature Normal body temperature is 98.6 degrees Fahrenheit.
- After death, the body loses or gains heat progressively until it equilibrates with that of the surrounding medium.
- Since corpse temperature can be easily and quickly obtained (see page XX), the search for a formula that uses this parameter to define the time of death has been sought for years.
As early as 1839, English physician John Davey undertook the study of corpse heat loss in London, and as late as 1962, T.K. Marshall and F.E. Hoare attempted to standardize this analysis when they established a computerized mathematical formula known as the Standard Cooling Curve.
- In the intervening years, and even since Marshall and Hoare, many others have attempted to devise similar schemes.
- Unfortunately, none of these have proven to be any more accurate than the current formula for heat loss of 1.5 degree per hour.
- The formula is: Hours since death = 98.6 – corpse core temperature / 1.5 This approximate rate of heat loss continues until the environmental temperature is attained, after which it remains stable.
That sounds simple enough. Unfortunately, it’s not quite that straight forward. The 1.5-degree-per-hour factor varies, depending upon the environment surrounding the body, the size of the corpse, clothing, and other factors. For example, a body in a temperate room will lose heat much more slowly than will one in an icy, flowing stream.
- And a body in a hot environment, such as an enclosed garage in Phoenix, Arizona, in August, where the ambient temperature could be 125 degrees Fahrenheit or more, will gain heat.
- The key is that the corpse will lose or gain heat until it reaches equilibrium with its environment.
- The coroner’s technician who processes the corpse at the scene takes a body temperature, and also measures the temperature of the surrounding medium—air, water, snow, or soil (if the body is buried).
Ideally, the body temperature is taken either rectally or by measuring the liver temperature, which may be a more accurate reflection of the true core body temperature. This requires making a small incision in the upper right abdomen and passing the thermometer into the tissue of the liver.
- This should only be done by a trained individual and under the direction of the medical examiner.
- Care should be taken not to alter or destroy any existing wounds on the body.
- Some people have suggested measuring the core temperature by inserting the thermometer into a knife wound or gunshot injury to negate the need to make a new incision.
This should never be done because the introduction of any foreign object may contaminate or alter the wound, which can be key evidence in the case. For practical reasons, the rectal temperature is usually taken. The sooner after death the body is found, the more accurately time of death can be assessed by this method.
- Once the body reaches ambient temperature, all bets are off.
- But even if done correctly and soon after death, body temperature determination is subject to several sources of inaccuracy.
- One assumption made in the calculations is the initial body temperature.
- The normal 98.6 degrees Fahrenheit is an average and varies from person to person.
Some people have higher normal temperatures than others. Women tend to run higher temperatures than do men. Illnesses associated with fevers can markedly elevate the temperature of the person at the time of death, while chronic illness, dehydration, or the presence of prolonged shock may lower initial body temperature.
- There is also some diurnal (basically morning versus evening) variation in body temperature in most people.
- All this means that the calculation begins with some degree of error.
- A dead body looses heat passively by three distinct mechanisms: radiation (heat lost as infrared heat rays), conduction (heat passed on to any object that contacts the body), and convection (heat lost into the moving air).
The state of the corpse and the environmental conditions greatly affect the rate of heat loss. Obesity, heavy clothing, warm still air, exposure to direct sunlight, and an enclosed environment slow heat loss. Fat and clothing make good insulators, so an obese person in a sweater will lose heat much more slowly than would a thin, unclothed corpse exposed to cold or moving air, water, or shade.
- Children and the elderly tend to lose heat faster, as do those who are chronically ill or emaciated.
- If the body is in contact with cold surfaces such as marble or cool concrete, heat loss will be greater.
- There’s still one more curve ball: Several days after death, as fly maggots begin to feed on the corpse, their activity and internal metabolic processes can at times raise the temperature of the corpse.
This should not be a problem for the forensic investigator, though, because once this insect activity is that far advanced body temperature is no longer of use. As you can see, heat loss is fraught with inaccuracies. Still, with early and careful measurement of the core body temperature and consideration for the conditions surrounding the corpse, a reasonably accurate estimate can often be made.
Let’s say two people are murdered in a home in Houston, Texas, during late summer. The bodies are discovered four hours after death. One body is left in the garage where the ambient temperature is 110 degrees Fahrenheit, while the other is in the living room where air conditioning holds the temperature at 72.
The corpse inside would lose heat at about 1.5 degrees per hour, so that if the medical examiner had evidence that the death had occurred four hours earlier, he would expect to find a core body temperature of approximately 92 to 93 degrees.1.5 degrees / hour x 4 hours = 6 degrees 98.6 – 6 = 92.6 If he found a different core temperature, he would revise his estimate.
But what if the victim were very old or young, thin, unclothed, or lying on a cold tile floor near an air conditioning vent? Under these circumstances, the heat loss would be more rapid. The core temperature could be 88 to 90 degrees, perhaps even less. If the medical examiner failed to consider these mitigating factors, an erroneous estimate of the time of death could result.
For example, if the core temperature was 88 degrees and he failed to adjust for the environmental conditions around the body, he could estimate that approximately seven hours had elapsed since death.98.6 – 88 = 10.6 / 1.5 = 7.1 hours An estimate of six to eight hours is quite different from an estimate of three to five hours.
- The killer may have an iron clad alibi for the former time period, and easily could since he hadn’t arrived at the crime scene at that time.
- He could have been having lunch with twenty people.
- But only four hours later, he might not have such an alibi.
- What of the body in the garage? The ME would expect the corpse to gain heat at the same rate of 1.5 degrees per hour.
Thus, the core temperature should be approximately 104 degrees Fahrenheit, or perhaps even higher.

Which organs are removed during post-mortem?
How an Autopsy or Post-mortem examination performed? In accordance with Section 174 of the Criminal Procedure Code and/or Section 176 of the Criminal Procedure Code, Investigation Agencies-Police can give inquest to conduct the Medico legal Autopsy to find out the cause of death, to determine the mode, manner and the mechanism of death, for detailed examination and documentation of injuries, to reconstruct the crime scene, to aid in the identification of the victim, to provide a linkage of facts and events surrounding the death.
- Medico-Legal Postmortem examination is performed at the request of the Police, Magistrate/Court.
- The Medical Officer does not have the authority to waive off postmortem examination.
- In such circumstances, the medical officer can serve as an advisor, but the final decision is made by the Investigation Agency( 3 ✔ ✔ Trusted Source Uniform guidelines for postmortem work in India ).
Autopsy is a macroscopic examination of a deceased person’s bodily cavities by a doctor. The microscopic examination may be used in addition to the macroscopic inspection, and depending on how severe the condition is, it may be necessary to remove a variety of tissue samples( 5 ✔ ✔ Trusted Source Post-Mortem Examination as a Quality Improvement Instrument ).
- The extent of an autopsy varies from the examination of a single organ such as the, to a very extensive examination and the time period vary depending upon the technique, usually it takes about one hour to three hours for post-mortem examination.
- Autopsy begins with a detailed external examination.
- The height, weight, identification marks (scars, tattoos) and other visible details are noted.
After this, internal examination begins. A Y or U- shaped incision is made from both shoulders joining over the sternum (breast bone) and continuing down to the pubic bone (i.e region above the genitalia). The skin and underlying tissues are then separated.
Rib cage and abdominal cavity are exposed. Neck and thoracic area are then exposed by opening the front of the rib cage. Advertisement Trachea (windpipe), thyroid gland, parathyroid glands, esophagus, heart, thoracic aorta and lungs are removed, followed by the removal of abdominal and pelvic organs intestines, liver, gallbladder and bile duct system, pancreas, spleen, adrenal glands,, ureters, urinary bladder, abdominal aorta, and reproductive organs are dissected out.
Next step is to remove the brain, An incision is made in the back of the skull from one ear to the other. The top flap of the scalp is forced forward and down over the face and the bottom flap is pulled down to the neck. Most of the skull is thus exposed.
A vibrating saw is then used to remove the top of the skull. The entire brain is then gently taken out of the cranial vault. The spinal cord may also be taken. Organs are then examined by a pathologist. Further dissection of the organs is performed as required. Microscopic examination may be required for tissue level studies.
The incisions made in the body are sewn closed after the autopsy. Removed organs are either retained or replaced to the body as demanded by the situation. Embalming and dressing of the body follows. Autopsied body is fit for normal funeral service. A number of studies may be performed as part of autopsy.
Can you see someone after a post-mortem?
What happens during a post mortem What happens during a post mortem? Pathologists perform post-mortem examinations to standards set by the Royal College of Pathologists. These standards include carrying out the post mortem in a respectful manner and with regard for the feelings of the bereaved relatives.
Most post mortems are carried out by pathologists who specialise in histopathology, which is the laboratory study of disease and of diseased tissue. Pathologists are helped by anatomic pathology technologists, who have had specialist training to assist pathologists. Post mortems are usually carried out in the hospital mortuary in a special post-mortem examination room, which is a similar to an operating theatre.
In certain circumstances, they may be carried out in the local public mortuary, or in a regional centre for specialist post mortems. The body will be moved respectfully from the place where the person died to the place where the examination is to be carried out.
A long incision is made down the front of the body to enable the internal organs to be removed and examined. A single incision across the back of the head allows the top of the skull to be removed so that the brain can be examined. Organs are examined carefully with the naked eye and dissected to look for any abnormalities such as blood clots or tumours.
If further information is required, postage-stamp-sized pieces of tissue may be retained for examination under the microscope or samples of body fluids taken for analysis in the laboratory. After being examined, the organs are returned to the body. Material is never retained without explicit consent from the coroner or next of kin.
The coroner might instruct the pathologist to perform further analysis on blood or a tissue sample; if this is the case the family will be informed. If the pathologist wants to keep tissue for research or teaching, they will only do so with written informed consent from the next of kin. Post-mortem facilities are regularly inspected to ensure that they work to the high standards set out by the,
Deaths in suspicious circumstances If the death is thought to have occurred as a result of criminal activity, then the post mortem will be undertaken by a forensic pathologist. Forensic pathologists investigate deaths where there are medico-legal implications, for example, suspected murder, death in custody and other complex medico-legal cases.
In such circumstances, a legal defence team (e.g. the barrister or solicitor of the accused person) can request a second post mortem by an independent forensic pathologist. This is allowed, because otherwise, the accused person could allege that the post-mortem was not carried out properly, resulting in the court case being dismissed without a clear outcome.
Retention of organs and tissue If the pathologist thinks it is necessary, the coroner will retain tissue blocks and slides. Similarly if there is a possibility of criminal involvement in the death, the tissue may be needed by the police as evidence, separate to the need of the coroner.
- In both cases, the tissue samples, blocks and slides or organs may need to be kept for several months or, in some cases, years.
- If tissue samples and organs have been retained, you should expect to be given a choice about what happens to them when they are no longer needed by the coroner.
- Your consent will be needed for any tissue samples or organs to be kept for future use such as research or education and training of medical staff.
Viewing the body You can view the body of the person who has died at any reasonable time before or after the post mortem. After a post-mortem, mortuary staff will prepare your relative’s body for you to see, should you wish to. The internal examination involves an incision down the front of the body which cannot be seen when your relative is dressed.
Why does an autopsy take so long?
The Typical Timeline for a Medical Examiner’s or Coroner’s Autopsy Report – You’re probably already aware that it takes an extended amount of time for families to receive the final autopsy report from a medical examiner or coroner – usually about six weeks.
- This fact is often publicized by the media if there is a high-profile homicide or suspicious death in your community.
- But why does it take so long to get a report from a typical autopsy? The answer lies largely in the backlog of the lab which processes autopsy samples, such as toxicology and histology samples, from the procedure.
Because city, county, and state coroners and medical examiners usually contract with one or just a few labs to process their autopsy samplings, receiving final results can take a while when the lab has a high number of samples to perform. This is especially true if you live in a highly populated metropolitan area.
What happens 15 hours after death?
Phase 3: Rigor Mortis – For approximately the first 3 hours after death the body will be flaccid (soft) and warm. After about 3-8 hours is starts to stiffen, and from approximately 8-36 hours it will be stiff and cold. The body becomes stiff because of a range of chemical changes in the muscle fibres after death.
What happens within 24 hours after death?
Decomposition Timing? –
- Brain cells can die if deprived of oxygen for more than three minutes. Muscle cells live on for several hours. Bone and skin cells can stay alive for several days.
- It takes around 12 hours for a human body to be cool to the touch and 24 hours to cool to the core.
- Rigor mortis commences after three hours and lasts until 36 hours after death.
- Forensic scientists use clues such as these for estimating the time of death.
What happens minutes before death?
What to expect in the last moments before death It can be difficult to know exactly when someone is going to die, or has died. This page details some of the most common signs. The following symptoms are often a sign that the person is about to die:
They might close their eyes frequently or they might be half-open Facial muscles may relax and the jaw can drop Skin can become very pale Breathing can alternate between loud rasping breaths and quiet breathing. Towards the end, dying people will often only breathe periodically, with an intake of breath followed by no breath for several seconds. This can be upsetting to witness as the person seems to stop breathing only to start again. There might be one or two last gasps a minute or so after what seemed like the last breath, before breathing eventually stops.
The moment of someone’s death is often very profound, even when you have expected it for a long time. You might want to talk to someone or call family and friends to let them know. You might prefer to be alone. Some people feel overwhelmed with sadness, for others it can take days, weeks or months to process how they feel.
- If you have been caring for the person you might feel exhausted, and the relief and finality of the moment of death can take you by surprise.
- Every person’s experience of dying and bereavement is unique.
- However you are feeling, there are organisations and resources to help you.

What are the 4 post-mortem signs that tell us about time of death?
After immediate postmortem changes, early postmortem changes start 3 to 72 hours after death. Early changes include algor mortis, rigor mortis, and livor mortis. Late changes, called decomposition, become apparent 72 hours after death and involves autolysis and putrefaction.
How is the head closed up after an autopsy?
– After the pathologist has finished the examination and the organs are returned to the body, the post mortem technician will sew back up the body. Once the Y incision and the head are sewn up, the autopsy (without brain and tissue analysis) is complete. Stitching of the incision is like that on a baseball. >
What is the last organ to function after death?
PEA – The first description of PEA in humans is found in an electrocardiographic study of the dying human heart 1 which was followed by several reports that described the electrocardiographic manifestations of 95 dying patients by the 1930s ( 12, 13 ).
- Currently, there is no single unifying available definition for PEA.
- A report from a National Heart, Lung, and Blood Institute Workshop defined PEA as ” a syndrome characterized by the absence of a palpable pulse, in an unconscious patient, with organized electrical activity other than ventricular tachyarrhythmias on ECG,” ( 22 ).
This definition excludes patients with left ventricular assisted devices and patients with agonal, very slow, and wide QRS complexes at the end of prolonged arrest. Most literature on PEA describes uncertainty regarding how it developed ( 23 ); the studies began assessment only during pulselessness, which is deep into the dying process ( Figure 1 ).
- Infrequent but dramatic causes such as massive pulmonary embolism (PE), cardiac tamponade, and tension pneumothorax have been stressed while more common causes are not discussed.
- There are several animal models of clinical death that progress to PEA and then asystole; normocarbic hypoxia, hypercarbic hypoxia, anoxia, and rapid bleeding are the most frequently used.
Interestingly, none of the animals in these studies entered VF during the process. Individual models of PEA correspond to common causes of death. Normocarbic hypoxia has been the most frequently studied, as high-altitude loss of consciousness leading to CNS and pulmonary arrest was noted in the early 1900s when balloon and then airplane flight resulted in unexplained deaths.
- Healthy pilots in normally functioning vehicles crashed with dead pilots.
- The early experiments with low oxygen developed a chamber which allowed carbon dioxide to be taken out but no oxygen to be added.
- This was described as a fitness to fly test and variations are still in use.
- As oxygen levels declined the subjects adapted with deeper respirations but no obvious distress.
At a level of hypoxia that was subject specific but ubiquitous, alterations in alertness and cognitive function became apparent, followed shortly by the loss of consciousness and CNS signals for respiration. Provision of normal oxygen resulted in awakening with no awareness of the loss of consciousness ( 24, 25 ).
Animal studies of the same model with continued hypoxia revealed the loss of vascular tone and blood pressure once the residual oxygen was depleted, then PEA developed and proceeded to asystole ( 26 ). Disease processes such as pneumonia and congestive heart failure (CHF) commonly follow this trajectory through cognitive dysfunction, loss of respiratory drive, and decay of circulation through PEA to asystole.
Hypercarbic hypoxic models are usually generated by obstruction of the endotracheal tube in a sedated animal ( 5 ). Common human correlates of loss of breathing include drug overdose, including excess anesthesia. Pulmonary and CNS arrest from more than safe anesthesia for the individual at that particular point in time provoked more resuscitations in Kouwenhoven’s first series than did VF ( 8 ).
Arrest from imbalance of need for pain control in the perioperative period and patient tolerance of medications over the recovery period continue to be a common cause of such arrests. These are highly survivable if identified by monitors early in the dying process. Other causes include high volume aspiration or foreign body aspiration into the trachea.
In the pre-hospital setting, this is the process followed in drowning. The distress caused by airway obstruction or drowning is obvious and dramatic. Failure of consciousness results in collapse, suggesting that brain failure is primary. Anoxic insults with pure nitrogen provoke rapid CNS and pulmonary arrest; a similar course is followed by the vascular system and heart.
- While infrequent, the human death equivalent is smoke inhalation or accidental gas exposure in work environments.
- The inflammatory insult frequently results in death even if the reversal is initiated early in the process.
- Bleeding to the point of collapse results in a compensatory tachycardia until the tissue hypoxia is sufficient to cause vascular collapse, followed by CNS then pulmonary collapse.
Decompensation of the vascular tone results in bradycardia, PEA, and ultimately asystole. Human models similar in progression include trauma, massive gastrointestinal (GI) bleeding, and rupture of a vascular aneurysm. Loss of vascular tone is also the initiating cause of death in anaphylaxis and sepsis.
The massive PE described as a saddle embolism stops circulation acutely as venous return, and pulmonary circulation, is entirely blocked. This results in prompt loss of CNS and its dependent respiratory drive. A common theme in these models is that the brain and lungs often have ceased function before vascular collapse results from global tissue hypoxia as residual oxygen is depleted.
Decompensation progresses over a period of minutes even after the pulse is lost. Even when vascular collapse is the primary event, brain and lung functions stops next. The heart is the last organ to fail. The heart stops following PEA, but PEA is not cardiac arrest.
The heart finally stops when it arrives at asystole, which is cardiac arrest ( Figure 1 ). The process of decompensation is distinct from the etiology of the collapse; many patients with heart disease as etiology do not currently enter VF in their dying process. Few patients without heart disease enter VF.
We obtained additional information about PEA through a study of in-hospital resuscitation which began in 1990 by data registry collection on all arrests in one hospital ( 7, 27 ). The registry contained longitudinal data for 20 years; the emergence of larger data sets and relocation of key team members resulted in discontinuation of the research study.
- The design included brain and pulmonary failure events from study initiation.
- Among the positive effects of this choice is that we saw and documented the shift from lung/brain arrest (1,800 patients) to PEA in about 300 subjects.
- PEA was the first rhythm identified in over 2,000 subjects.
- Loss of pulse at any point resulted in similar rates of hospital survival to those first found in PEA.
The project stressed standardized definitions and interrater reliability, which allowed us to redefine the eligible subjects and participate in the first study that validated a decision aid for stopping failed resuscitative efforts. The aid had been based on a pulseless subject set ( 28 ).
While the research registry closed, the first author continues to lead the code team and committee and attends codes regularly as a clinician educator. The hospital has over 600 events yearly, and the patterns described above have not changed. Clinical practice and research in a hospital environment make the continuum of the dying process apparent.
Echocardiographic studies of PEA have established that some subjects have weak cardiac contractions, and others have little or no evidence of wall motion. These have been described as Pseudo-PEA and PEA respectively ( 29, 30 ). We conducted a prospective, observational study of patients with no history of cardiac disease who were diagnosed with brain death due to intracranial hemorrhage.
Institutional review board (IRB) approval was obtained, and families were approached for consent. Three patients were enrolled. These patients were to receive, according to family wishes, hospice/end of life care with no attempt of cardiopulmonary resuscitation or organ harvesting for transplant. Monitoring of blood pressure, oxygen saturation, heart rate and rhythm, and a two-dimensional transthoracic echocardiogram were performed throughout the course of cardiovascular collapse and asystole.
All patients had stable vital signs at the time of disconnection from the ventilator and progressed through PEA to asystole over 12 to 21 minutes, with time to PEA being around 10 minutes. The cardiac function began to decline as oxygen saturation decreased.
As the vascular system decompensated, changes in left ventricular ejection fraction (LVEF) and left ventricular internal diameter at diastole (LVIDd) occurred. Diastolic dysfunction was a prominent portion of the collapse in all subjects. Pseudo-PEA was clearly present at vascular collapse and progressed over minutes to PEA and then asystole ( 31 ).
Pseudo-PEA and PEA are regular phases in a dying process that can be used to estimate time from collapse. The decline through PEA to asystole is also observed during organ harvest for transplant, which is begun only at asystole. The strongest evidence that death did not results from failure of the heart or lungs is that transplantation results in normal function of the organ(s), despite a period of asystole ( 32 ).
Do they put organs back after autopsy?
The funeral – Once the autopsy is complete, the body can be collected by the family’s chosen funeral director. If some of the organs have been retained for further testing, the may need to be delayed for a few days or weeks if the family wants the body to be whole before it is buried or cremated. In this case, the funeral director can arrange to embalm the body.
Why postmortem is not done at night?
After all, why post-mortem is not done at night? Know the reason. You must have heard that when a person dies in an accident or a person commits suicide, then in such cases the post-mortem of the body is done by doctors and forensic team to find out the real cause of death of that person. Let us tell you that post-mortem is done only by forensic science experts, who have more knowledge of chemical science. You must have also heard that no matter how much emergency it is, the post-mortem is never done in the night time. There is a special reason for doing this.
- Let us tell you what is the reason behind doing this.
- After all, why postmart is not done at night? According to several reports, doctors do not recommend conducting post-mortem at night.
- It is said that the post-mortem of any dead person should be done within 6 to 8 hours of his death.
- If the time exceeds eight hours, then it becomes a bit difficult to find out the cause of death.
Because after eight hours, many natural changes start taking place in the dead body, due to which there is a high possibility of the investigation being tied. Also, there can be many changes in the post-mortem report as well. In such a situation, it is advised that the postmortem should be done as soon as possible.
- However, despite the late post-mortem is not done at night and the biggest reason for this is the effect of “artificial light”.
- Note that in the night time, in the light of LED or tubelight, the wounds of the dead body appear purple instead of red.
- Forensic science has never mentioned the purple injury.
At the same time, when the dead person is examined in natural light, the color of the injury appears different from the color seen in the tubelight. That’s why post-mortem is not done at night. If this happens, it can change the reason for the wound in the postmortem report and at times it can become a big problem in police action.

How is an autopsy done on a body?
How is an autopsy done? – Autopsy procedure begins with the general and ends with the specific:
First, a visual exam of the entire body is done, including the organs and internal structures. Then, microscopic, chemical, and microbiological exams may be made of the organs, fluids, and tissues. All organs removed for examination are weighed, and a section is preserved for processing into microscopic slides. A final report is made after all lab tests are complete. Autopsies may last 2 to 4 hours. The results of lab tests on samples of body fluids and tissues may take a few weeks to be returned.
What does a body look like after being in the morgue for 2 weeks?
Open casket after 10 years what to expect? – A dead body begins the decomposition process in different phases. The first stage begins within the first 2 hours, when the body decomposes, starting with tissue damage. You may also witness foam in certain parts of the body. Our body has over 200 bones and trillions of cells and microbes. So the decomposition may differ depending on the burial conditions. Wooden caskets are the most common caskets used for burial. However, the underground pressure can cause the coffin to be squished or distorted, making it difficult to open casket if you need to in a few years.
- Answering the question of how does look like the body in casket after 5 years, there are four primary stages of decomposition, which may also include mummification due to environmental conditions.
- The third stage begins with mass loss and liquefaction, which slowly proceeds toward the fourth stage.
- You’ll notice that the corpse starts losing its teeth from the mouth.
However, if you open a casket after 10 years, you might witness Adipocere, where the body undergoes a chemical reaction and releases a soap-like substance (grave wax). Grave wax is produced by decomposing body fat when the deceased has been in the casket for at least 10 years.

How long does a digital post-mortem take?
How is a digital autopsy carried out? – A regular autopsy isn’t simply an operation. It means opening up a body, taking out all of the organs, cutting them up and analysing them individually. The post-mortem can then take up to 4 hours. A digital autopsy sidesteps the cutting up bit, making the whole procedure more efficient.
- It uses a CT scan to map the body’s organs in a similar way to logging them all physically.
- The data from the scan is then processed to create a 3D, whole body reconstruction.
- From there, a normal analysis is carried out.
- A 3D representation of a body, made up of approximately 3,400 slices of 0.5mm each, can be created in just over 3 minutes.
It can then be saved like a regular file on computer, where a surgeon armed with what’s known as a virtual scalpel can peel away layers of skin, tissue and organ all from the comfort of a desk, cup of tea at the ready.
How is the head closed up after an autopsy?
– After the pathologist has finished the examination and the organs are returned to the body, the post mortem technician will sew back up the body. Once the Y incision and the head are sewn up, the autopsy (without brain and tissue analysis) is complete. Stitching of the incision is like that on a baseball. >
