Name 5 groups of pain in cancer
Bone pain Visceral Pain Infection Neuropathic Headache and raised ICP
Bone pain:
Features and Treatment
Either a dull ache over a large area or localised tenderness. It is often worse my weight baring or movement.
NSAIDS, radiotherapy, bisphosphonates
Visceral Pain
Features and treatment
Including visceral stretch, colic pain and bladder spasm
Dull, deep seated pain, not well localised, maybe tender over an organ (e.g. liver). Can be spasmodic (e.g. bladder spam or bowel colic).
Treatment:
- Analgesic ladder
- Colic pain: antispasmodic: subcut. hycosine butylbromide
- Bladder spasm: oral oxybutynin
Heartache and raised ICP
Features and Treatment
Dull oppressive headache. Pain worse in when waking, coughing or leaning forward. Often associated with nausea and vomiting.
Treatment:
NSAIDs/Paracetamol
Corticosteroid: 16mg Dexamethasone daily (removes oedema)
Neuropathic pain
Features and Treatment
Pain in area of abnormal sensation, localised to dermatomes, numbness, hyperaesthesia, autonomic changes. Character: ‘pin & needles’ or ‘burning’.
Treatment:
- Gabapentin 100-1200mg tds
- Pregablin 25-300mg bd
- Corticosteroids if nerve is compressed (e.g. MSCC)
Explain each stage of the analgesic ladder
Stage 1: Paracetamol 1g qds
Stage 2: Weak opioid (e.g. codeine 240 mg)
+ Stage 1 - often co-codamol
Stage 3: Strong opioid: e.g. Morphine + Step 1
All steps can also have adjuvants.
NSAIDS/anti-epileptics/antidepressents/corticosteroids
What are the 3 strengths of co-codamol. What is the maximum number of tablets that can be taken each day?

What is the maximum daily dose of co-codamol?
This is equivalent to how much morphine?
240mg of co-codamol (30mg/500g, two tablets, ads

How do you prescribe for breakthrough pain?
Eg for MST 20mg bd
1/6 of the daily dose of morphonie
5-10mg oromorph p.r.n (hourly)
On prescription must write hourly not prn.
If you want to titrate up from co-codamol
Work out daily dose of morphine, co-codamol and how much for break through pain.
eg 240mg co-codamol= 24 morphine + 20mg oromorph = 44mg daily for MST
= 20/25mg mg bd
