Pain Management Flashcards
How is pain assessed in practice?
Biological/ neurophysiological aspect - pain intensity - pain score/ scale
Functional interference - acute pain is DrEAMS and chronic pain
Psychological distress
What is step 1 for pain management?
Aspirin
Paracetamol
NSAID
What is step 2 for pain management?
Dihydrocodeine
Codeine
Hydrocodone
Tramadol
What is step 3 for pain management?
Morphine
Oxycodone
Methadone
Levorphanol
Fentanyl
What is involved in pain sensation?
Peripheric detection
Axonal transmission
Spinal modulation
Descending inhibitory pathways
Perception and interpretation
What principles should intraoperative pain management follow?
Promotion of early functional return
Multimodal analgesia
Opioid sparing analgesia techniques
PROSPECT recommendations
Need to be individualised
What are types of multimodal analgesia?
Locoregional analgesia
Ketamine
Magnesium sulfate
Alpha-2 agonists
Paracetamol
Non-steroidal anti-inflammatory drugs
What is the perioperative pain management approach?
1 - classify the patient if prior opioid use
2 - assess for risk modifiers
3 - define perioperative risks of ORAEs
4 - employ risk based management plan
What is first line for pain management moderate to severe postoperative/ post-trauma pain?
2 regular non-opioids and one opioid
Paracetamol and ibuprofen
+/- locoregional analgesia
+ opioid
What is second line for pain management moderate to severe postoperative/ post-trauma pain?
Ketamine if severe or nefopam to decrease opioid induced sedation
What is third line for pain management moderate to severe postoperative/ post-trauma pain?
Gabapentin and discussion with patient
Antiemetic or clonidine for nausea and for opioid withdrawal
What are types of CYP2C9?
Acenocoumarol and warfarine
What are types of CYP2D6?
Codeine and tramadol
What are types of CYP3A4?
Oxycodone and rifampicin
What can be done to prevent postoperative opioid related harm?
Pre-operative opioids
Reliance on pain scores
Long acting opioids
Over emphasis on opioids for discharge opioid prescription
Repeat prescriptions
