Q

what are some medications you use for dyspnea?

A 
Bronchodilators (for bronchospasm)
	Diuretics
	Steroids
	Anti-anxiety medications

	Cough suppressants
	Oxygen
31
Q

what medication might you give to use as a cough suppressant?

A

codeine

32
Q

what is the #1 medication for dyspnea?/

A

opioids
Decreases the sense of breathlessness
Decreases sensitivity to CO2
Need not wait until last hours of days to start

33
Q

would you give oxygen to a patient in the last hours of dying?

A

no not unless the pt in panicking

34
Q

what are some fluid and nutrition symptoms during EOL?

A

thirst, no hunger (not common sensation at EOL), dry mucous membranes, delirium, anorexia and cachexia

35
Q

does artificial hydration help with thirst/

A

no

36
Q

is dehydration related to symptom of thirst during end of life?

A

no

37
Q

why do you experience anorexia and cachexia?

A

caused by metb disturbance of Ca–loss of protein

38
Q

what are the 3 psychoscoail process families engage in?

A

fighting back
letting nature take its course
waffling

39
Q

what occurs during fighting back? (psychosocial processes families engage in) fluid and nutrition EOL

A

The knowledge that reduced intake is normal for someone who is dying is in direct conflict with a family’s desperate attempt to prevent just that
Families ask about IV, Tube feedings, TPN
Focus is on food intake – force feeding, bringing in food

40
Q

what occurs during letting nature take its course (psychosocial processes families engage in) fluid and nutrition EOL

A

Understand that no amount of nutrition of fluids with prevent the patient from dying
Nurture pt in other ways – mouth care, being present at bedside

41
Q

what occurs during waffling? (psychosocial processes families engage in) fluid and nutrition EOL

A

Go between accepting approaching death and wanting to keep fighting
Some care givers fit in here as well

42
Q

what are the benefits of dehydration?

A

Natural anaesthetic effect, reduction in resp secretions, decreased GI fluid, reduced urine output

43
Q

what are the risks of hydration?

A

Edema, ascites, resp congestion and distress, diarrhea, nausea, pain

44
Q

what are some neurololgical changes near death?

A 
Hypoxemia 
Metabolic imbalance 
Acidosis
 Toxin accumulation due to liver and renal failure 
Adverse effects of medication 
Sepsis 
Disease-related factors 
Reduced cerebral perfusion
45
Q

treatment for EOL

intent to relieve by ___&___
intent to oberve____

A

Intent to Relieve by Reversal

Intent to Relieve by Sedation

Intent to Observe Delirium

46
Q

what is the criteria for treatment for relieve by reversal?

A
  • Known patient wish for intervention where possible, even if chances are low
  • If readily reversible
  • If potentially reversible e.g. opioid neurotoxicity
  • If not dying, i.e. earlier stages
  • If dying, trial attempts – only if patient had wanted active treatments and reverse is likely; otherwise no.
47
Q

what is the criteria for treatment for relieve by sedationl?

A

• If delirium unpleasant and/or worsening• If patient did not want active treatment• If treatment is futile or unlikely to improve delirium• If conditions are unsafe for patient, family or staff e.g. wild agitation, violence

48
Q

what is a good drug to use (neuroleptic) to give for delirium? tell me more about this drug

A

Haloperidol is the most suitable drug therapy for the treatment of patients with delirium near the end of life. Haloperidol is generally considered the gold standard. It is a longer acting drug(48) which can be given PO, SC, IM or IV. In delirium, a suggested regimen is 0.5–1.5mg PO (mild), 1.5– 5.0mg PO (severe) or 10mg SC or IV (very severe) [one report of up to 250mg/24hr.

49
Q

if a small risk of slight cognitive impairment is not a concern, what drug would you give?

A

Chlorpromazine

50
Q

what drug would you give as an alternative to haloperidol and has a higher sedation? what else is it used for? dose?

A

Methotrimeprazine.
It is a higher sedation drug at doses of 15mg or above. It can be given PO, SC, IV as well as SL. Very low doses are used for nausea (0.5–2.5mg) but control of delirium usually requires 10–15mg for mild and up to 50mg for severe delirium. These may be given q4–8h initially, then less often once controlled

51
Q

should you use a benzo for delirium and cognitive issues?

A

no they do not clear the sensorium or improve cognition. it may be used as an adjunct primary therapy with haloperidol or another neuroleptic for delirium

52
Q

would you use lorazepam for cognitive issues and delirium? caution for what kinds of people?

A

alone it appears to be ineffective and is in fact associated with treatment-limiting adverse effects but it COMBO may provide quicker and more effective control

Particular caution should be used in the elderly or those with hepatic failure.

53
Q

doses for lorazepam?

A

Doses vary widely from 0.5mg to 5mg. In mild cases of delirium, it should be avoided as noted above or used on a PRN only basis for agitation until the neuroleptic provides overall control, especially if the goal is reversal of delirium.

54
Q

when is midazolam used/ for what?

A

is also frequently used in delirium, but is more helpful for the restlessness aspect. In acute dosing, it is short-acting and rapidly effective

55
Q

what is propofol ?

A

a short-acting anesthetic, could also be used.

56
Q

what is Phenobarbital?

A

may be helpful or in combination if midazolam fails to provide adequate sedation in refractory cases.
