Flashcards in Post Mortem Changes and Bodies from Water Deck (89)
How long does it take for irreversible brain damage?
In the hospital, what four things are death determined by?q
1. Cessation of breathing
2. No response to pain or voice
3. No pupillary response to light
4. Cessation of pulse and heart beat
How many doctors establish brainstem death?
What two organs show the most cellular resilience to hypoxia?
Bone and corneas (48 hours)
What two organs show the least cellular resilience to hypoxia?
Brain and spinal cord (4 minutes)
What do post mortem changes do to confirmation?
They confirm death. Resuscitation is futile.
What is Post Mortem Interval
Post-mortem interval (PMI) is the time that has elapsed since a person has died.
What colour will abrasions which occur in life be?
What colour will abrasions that occur in death be?
Orange and parchmented
What sort of sites do animal artefacts occur in?
What are these artefacts of:
Gooseflesh (Cutis anserina)
Artefacts of immersion
What is skin splitting an artefact of?
Fire and heat
What can extradural haematoma be an artefact of?
Fire and heat
What post mortem changres occur in hours?
What post mertem changes occur in days to weeks?
What two post mortem changes occur after months?
Chill of death?
Darkening of death?
Stiffening of death?
What can be a useful indicator of PMI in the first 24 hours of death, only in temperate and cool climates?
When assessing for algor mortis what method of determining core body temperature must you avoid in sexual cases?
When assessing for algor mortis what method of determining core body temperature could you use instead of anal?
Liver by subcostal stab- creates a wound
Loss of heat from the body due to conduction, convection and radiation. Little heat lost by evaporation
Who will cool quicker- an obese individual or a thin person?
obese- larger surface area
What can there be a slight rise of temperature in after deatgh?
What is Henssge's Normogram based on?
a mathematical cooling model
What does Henssge's Normogram allow for correction of?
Immersion in water
What does Henssge's Normogram assume?
Normal body temp at death
No ariation in ambient temperature during cooling period
What are some exclusions to using Henssge's Normogram?
1. Near strong heat source
2. Near cooling source
3. Floor tiles
4. Abnormal body temperature at death
5. Body moved between death andtemperature reading i.e. fridge
