Week 10: Hospice and Palliative Care - Dying as a Transition Flashcards
What is the ultimate cause of death?
Lack of oxygen (cardiac and brain)
When is a person considered dead according to Harvard Criteria?
- Unreceptive and unresponsive
- No movements and/or breathing
- No reflexes; pupils are fixed, dilated, not responsive to light, no blinking, no ocular movement
- Flat EEG, no activity in the cerebrum (brain waves)
- No circulation to, or within the brain
What is the definition of a brain death?
Irreversible cessation; entire brain including brain stem
What is the definition of a coma?
Profound unresponsiveness due to illness or injury. Won’t speak, open eyes, engage in purposeful behaviors
What is the definition of a vegetative state?
Depressed consciousness, brain stem function and breathing independently. Person may respond to pain or loud sounds, involuntary motions, etc.
- persons who are in a vegetative state of >1 year are in a permanent vegetative state
What are signs of brain death?
- Pupils stay in mid-position and do not react to light
- The eye does not blink when touched
- The eyes do not rotate in the socket when the head is moved from side to side or up and down
- The eyes do not move when ice water is placed in the ear canal
- The patient does not cough or gag when a suction tube is placed deep into the breathing tube
- The patient does not breathe when taken off the ventilator
What does Neocortical mean?
Least extreme form - upper part of the brain where thoughts, pleasure, pain and volition reside - no longer functions
What does cerebral death mean?
The next step - comes when only the cerebellum and the brainstem are active
What does Whole Brain Death mean?
Brainstem itself has stopped functioning - only type of brain death that is recognized in the US
What does UDDA mean?
Uniform Determination of Death Act - individual who has sustained either irreversible cessation of respiratory function or cessation of all functions of entire brain
What does agonal movement mean? and what types of movements happen before clinical death?
- The body’s ultimate response to a lack of oxygen - the moment before the moment of death
- Muscle spasms, gasps, and possibly a convulsion may occur
Define these 3 different mortis’
- Algor Mortis
- Livor Mortis
- Rigor Mortis
- Algor Mortis: temperature of the body postmortem; normal circumstances (one degree per hr)
- Livor Mortis: the color of death; RBCs settle to lowest part of body, postmortem stain (reddish-purple discoloration)
- Rigor Mortis: the rigidity of death; face, trunk, limbs and organs; contraction of muscle (2-6 hours after death)
Within 24 hours of death, there are additional changes to the body… what are they?
Decomposition
- Autolysis : cell self-destruction; enzymes
- Putrefaction (rotting): 2-3 days after death; smell due to decaying RBCs and intestinal gas
- Breaking down of the body
What are the 5 stages of grief (of dying)
- Denial: No not me, it can’t be true
- Anger: Why me?
- Bargaining: Maybe if I ask nicely or pray
- Depression: Individual can no longer deny his or her illness (reactive, preparatory)
- Acceptance: Person is neither angry nor depressed - a quiet degree of expectation
What are some evaluation of the five stages?
- Existence of stages has not been demonstrated
- People may not move through stages 1 –> 5
- Limitations of methods
- Line is blurred between prescription and description
- Totality of the person is neglected
