Name 3 causes of nausea and vomiting
Bowels - Mucositis, constipation, infection, obstruction
Brain 0 raised ICP
Biochemical - Medications, hypercalcaemia, uraemia, infection, hypomagnaesaemia
How do these places play a role in Nausea
Gut wall?
Chemoreceptor trigger zone?
limbic?
vestibular?
Gut wall: distension stimulates vagus - constipation, obstruction, chemo stimulates enterochromaffin cells
Chemo - uraemia, drugs, chemotherapy, hypercalcaemia
Limbic - emotion
Vestibular - motion sickess / vertigo
Name some antiemetics ///
Bowel only cause
Domperidone Hyoscine butylbromide
Bowel+brain
Haloperidol / metoclopramide
Brain
cyclizine / levopromazine
Why shouldn’t you prescribe cyclizine and metoclopramide
c - constipating
M - diarrhoea
Counteract each other in bowel
What is pain

Goals of Nx in pain

When is the WHO pain ladder used
Cancer pain
3 Stages of pain ladder and Eg of 2 drugs in each
Simple
-Para / NSAIDs
Weak opiods
Codeine / tramadol
Strong
-Morphine, oxycodone, buprenophine, fentany, methadone, ketamine
When you move from weak opiods to strong do you continue the weak?
All have a CEILING EFFECT therefore REPLACE with strong opioid rather than add
Which do we prefer morphine or oxycodone?
Oxycodone - stronger + less SEs
Can get tablets and immediate release
-Deal with background and breakthrough pain
Common SEs with morphine?
Constipation, sedation, nausea, dry mouth
[-> Stimulant laxatives + PRN antiemetics]
Intresting Resp fact with opiates?
tend to reduce RR BUT increase tidal volume!
Which can you give if RR<8 AND SpO2 <92% due to opioids?
Naloxone
When would you use fentanyl ? How long does it take to work?
For STABLE opioid responsive pain
Indicated for poor oral route, or renal impairment
12 hours to reach analgesic concentration so not for acute pain (lasts 72 hours)
Good drug for pain+
Neuropathic pain?
muscle spasms?
compression sx?
bone pain?
Neuro
amitryptilline
pregabalin, gabapentin
Spasms
Baclofen / benzos

Breathless
PRN opioid SC and SC benzodiazepines
