Q

What are the pharmacotherapeutic measures for dyspnea?

A

1) Opioids (eg morphine)

Q

What is fecal impaction with overflow/spurious diarrhoea?

A
  • Impacted stools in colon but softer stools leak around it
    ~ Can be mistaken as diarrhoea
  • Tf, important to do digital rectal exam to feel for impacted stools
17
Q

What are the causes of constipation?

A

1) Drugs (eg opioids, antidepressants, calcium and iron supplements)

2) Metabolic conditions (eg dehydration, hypercalcemia, hypokalemia, uremia)

3) Neurological disorders

4) Structural (obstruction, adhesions)

5) Pain (anal fissures, hemorrhoids)

6) General (reduced mobility, decreased intake, weakess)

18
Q

What are the pharmacotherapeutic measures for constipation?

A

1) Stimulant laxatives (eg Senna, Bisacodyl/Dulcolax)

2) Osmotic laxatives (eg Lactulose, Macrogol/Forlax, PEG)

3) Bulk-forming laxatives (eg Fybogel)
- Not often used in pall care as most px struggle to drink the req. 1.5L/day

19
Q

What is the action of stimulant laxatives (eg Senna, Bisacodyl)?

A
  • Stimulates peristalsis of the smooth muscle of intestine
20
Q

What are precautions and adverse effects of stimulants laxatives?

A
  • Px bowel obstruction or colic (localized pain in the abdomen or urinary tract that comes and goes)

Adverse effects:
- Dehydration
- Colic

21
Q

What is the action of osmotic laxatives (eg Lactulose, macrologol, PEG)?

A

Draws fluid into bowel by osmosis
- Softens feces (to stimulate peristalsis)

22
Q

What are the precautions and adverse effects of osmotic laxatives?

A
  • Px must drinks lots of fluids

Adverse effects:
- Colic
- Flatulence
- Dehydration
- Electrolyte imbalance

23
Q

What are non-pharm measures for constipation?

A
  • Adequate fluid intake
  • Increase intake of high-water content foods (eg soups, yoghurt, jelly)
  • ^ Mobility
  • Encourage toileting in the morning after breakfast
24
Q

What defines diarhhoea and its severity?

A

> 3 episodes of unformed stools in a day

  • Grade 0
  • Grade 1: Increase in <4 stool episodes compared to pre-treatment
  • Grade 2: Increase in 4-6 episodes
  • Grade 3: Increase in >6 episodes
  • Grade 4: Increase in >10 episodes
25
Q

What are the causes of diarrhoea?

A
  • Not to be confused with spurious/overflow diarrhoea
  • General
    ~ GE
    ~ Broad-spectrum Abx
    ~ Enteral feeding (as it has high osmotic content, rapid and high volume feeding)
    ~ Tumor
  • Treatment-related
    ~ Chemo/radiotherapy
    ~ Post-surgical/procedural
26
Q

IMPT:
What are the pharmacotherapeutic management for diarrhea?

A
  • Loperamide 2-4mg tds, max 16mg/day)
  • Buscopan
  • Codeine phosphate
27
Q

IMPT:
What drugs should be avoided in diarrhea?

A
  • Lomotil (diphenoxylate/atropine)
    ~ Can cause delirium
28
Q

What are the non-pharm measures for diarrhea?

A
  • Non-milk diet
  • Oral rehydration salts or isotonic drinks
    ~ Replace electrolytes lost due to hyponatremia or hypokalemia
  • Barrier cream
29
Q

What is delirium and its subtypes?

A
  • Acute deterioration in cognitive function
  • Fluctuations in conscious level
  • Disorientation and confusion

Subtypes:
1) Hypoactive - Confusion and somnolence
2) Hyperactive - Hypervigilance, restlessness, agitation
3) Mixed-alternating features

30
Q

How to assess for delirium?

A
  • Confusion assessment method (CAM)
    ~ Acute onset and fluctuates
  • Inattention
  • Clouded consciousness
    ~ Ranges from hyper-awake to sleepy
  • Disorganized thinking
    ~ Rambling, irrelevant, incoherent conversation
31
Q

What are the causes of delirium?
Acronym: DELIRIUM

A
  • Drugs
  • Electrolytes
  • Lung/liver (Pneumonia, pulmonary embolism, hepatic encephalopathy)
  • Infections
  • Retention/Restraints (Urinary retention, fecal impaction, restraints)
  • Intracranial (brain metastasis, stroke, seizures)
  • Uremia
  • Myocardial (MI)
32
Q

IMPT:
What is the pharmacological measures for delirium?

A
  • First line
    ~ Subcutaneous Haloperidol
    ~ Risperidone (for px with Parkinsons or EPS from haloperidol)
    ~ Subcutaneous Midazolam (if px is restless and uncooperative)
  • Second line (if px still agitated)
    ~ Oral/sublingual Olanzepine
    ~ Chlorpromazine
33
Q

What are the non-pharm measures for delirium?

A
  • Frequent reorientation
  • Calm environment
  • Emotional support and avoid confrontation
  • Clear verbal instructions
  • Promote a normal sleep-wake cycle
  • Correct sensory deficits
  • Minimise physical restraints
