- Parkinsons
- Brain tumor
- Spinal cord compression
- Autonomic dysfunction

Q

Pharmaco management of constipation

A

Stimulant laxatives (e.g. senna, bisacodyl/dulcolax)

Osmotic laxatives (e.g. lactulose, macrogol (forlax), polyethylene glycol (PEG))

Bulk-forming laxative (e,g. Fybogel)

16
Q

MOA, precautions and adverse effects of Stimulant laxatives (senna, bisacodyl)

A

MOA: Stimulates peristalsis by stimulating smooth muscle of intestine

Precaution: unsuitable for pts with complete bowel obstruction or with colic (pain in stomach due to wind or obstruction)

Adverse effects: dehydration and colic

17
Q

MOA, precaution and adverse effects of osmotic laxatives (lactulose, macrogol, PEG)

A

MOA: draw fluid into bowel by osmosis, soften faeces, stimulate peristalsis

Precaution: Must drink fluids!

Adverse effect: colic, flatulence, dehydration, electrolyte imbalance in debilitated pts

18
Q

Why are bulk-forming laxatives (e.g. Fybogel) not used in palliative care?

A

Not commonly used as most patients struggle to drink the required 1.5litres/day!

19
Q

Non-pharmaco management of constipation

A
  • ensure adequate fluid intake (increase intake of high-water content foods)
  • encourage mobility
  • encourage toileting in morning after breakfast
  • maintain privacy, avoid bedpans
20
Q

What is diarrhoea?

A

Passage of >3 episodes of unformed stools in a day

21
Q

What is the classification of diarrhoea (grade 0-4)?

A

Grade 0: No severity

Grade 1: Increase in <4 stool episodes

Grade 2: Increase in 4-6 episodes

Grade 3: Increase in >6 episodes

Grade 4: Increase in >10 episodes

22
Q

Causes of diarrhoea

A

Note: exclude “spurious/overflow diarrhoea” from laxative over-use

  • GE causes
  • Immunocompromised, receive multiple broad-spectrum antibiotics
  • Enteral feeding: high osmotic content, rapid or high-volume feeding, hypoalbuminaemia
  • Tumour related: rectal/pancreatic cancer
  • Treatment-related: chemotherapy, radiotherapy, post surgical/procedural
23
Q

Pharmaco management of of diarrhoea

A
  • Loperamide
  • Hyoscine Butylbromide (Buscopan!)
  • Codeine phosphate
  • Avoid Lomotil (Diphenoxylate/Atropine) in elderly as Atropine can cause delirium
24
Q

Non-pharmaco management of diarrhoea

A
  • Exclude spurious diarrhoea
  • Non-milk diet
  • Oral rehydration salt or isotonic drinks
  • Replace electrolyte lost due to hyponatremia/hypokalemia
  • Prevent pressure injury with barrier cream, pressure relief mattresses and regular turning
25
Q

What is delirium?

A

Acute deterioration in cognitive function accompanied by fluctuations in conscious level, leading to DISORIENTATION and CONFUSION

26
Q

3 subtypes of delirium

A
  1. Hypoactive: confusion and somnolence (sleepy, drowsy)
  2. Hyperactive: hypervigilance, restlessness and agitation
  3. Mixed alternating hypo and hyperactive delirium
27
Q

Causes of delirium

A

Drugs
- anti-cholinergic
- steroids
- opioids
- tricyclic antidepressants (TCA)

Electrolytes
- hypercalcemia
- hypoglycaemia
- hypernatremia
- hyponatremia

Lung/liver
- pneumoia
- pulmonary embolism
- hepatic encephalopathy

Infection
- consider possible infection sites

Retention/restrain
- urinary retention
- fecal impaction
- use of restraint

Intracranial
- brain metastasis
- stroke
- seizures

Uremia

Myocardia
- MI

28
Q

Assessment for delirium

A

Confusion Assessment Method (CAM): 4 features

Feature 1: Acute onset and fluctuating course

Feature 2: Inattention (difficulty focusing attention)

Feature 3: Clouded consciousness (ranging from hyper-awake to sleepy)

Feature 4: Disorganised thinking (rambling/irrelevant/incoherent conversation)

29
Q

General management of delirium

A
  • Treat any potentially reversible causes
  • Optimise pain control
  • Pharmaco management
  • Non-phamaco management
30
Q

Pharmaco-management of delirium

A

First line:
- Haloperidol
- Risperidone (for pts with Parkinson’s or those who developed EPSE with haloperidol)

Second line (if pt is still agitated despite above):
- switch from haloperidol to sublingual Olanzepine
- Chlorpromazine

31
Q

Non-pharmaco management of delirium

A
  • frequent reorientation
  • calm environment (avoid sensory deprivation and overstimulation)
  • clear verbal instructions
  • emotional support (avoid confrontation, do not confront delusional beliefs, focus on emotions not content)
  • promote a normal sleep-wake cycle
  • correct sensory deficits (glasses & hearing aids)
  • minimise physical restraints (consider discontinuing IV or urinary catheters)
  • minimise room and staff changes
  • request family bring familiar items and sit w patient
