Post-Operative Pain Management: A Multimodal, Opioid-Sparing Approach

Poorly managed post-operative pain interferes with early mobilisation, breathing exercises, nutrition and sleep. Pain control is therefore part of recovery, not just comfort. The current preferred approach is 'multimodal analgesia'.

What is multimodal analgesia?

Multimodal analgesia uses several medications with different mechanisms together at lower doses. The goal is to increase efficacy while reducing the side effects that come from a high dose of any single drug. It particularly reduces opioid use, limiting nausea, constipation and sedation.

Commonly used components

• Paracetamol — regular scheduled dosing as the backbone
• NSAIDs (in suitable patients) — reduce inflammatory pain
• Local anaesthetic infiltration at the wound
• Regional blocks (e.g. TAP block, epidural) — for major abdominal surgery
• Short-course opioids when needed, at low doses
• Antiemetic support

Regional blocks

Regional techniques such as the TAP block numb the anterior abdominal wall and clearly reduce pain in the first 24–48 hours. This eases early mobilisation, breathing exercises and return to oral intake. The decision is made together with the anaesthetic team based on procedure and patient factors.

When are opioids needed?

Why are you asked your pain score?

Nurses and doctors ask you regularly for a 0–10 pain score. This guides drug dose, need for a rescue dose and possible blocks. There is no need to under- or over-state your pain — an honest score enables the best management.

Pain management at home

• Take prescribed medications on schedule
• Do not increase doses yourself when pain rises; contact the team
• Continue wound care, gentle walking and breathing exercises
• If constipation develops, use the support recommended by your doctor
• Watch for fever, redness or discharge as well as pain
