Less pain, less opioids — the multimodal post-operative analgesia protocol
For decades, opioids were the cornerstone of post-operative pain control. The result: 6-10% of patients who never used opioids before surgery became chronic users after. The modern protocol replaces opioids-first with multimodal analgesia — combining drugs that target different pain pathways at the same time, achieving better pain control with fewer side effects. Dr. Khaled Ghalwash and Dr. Mohamed Ghalwash use multimodal analgesia as the default for every elective operation.
The first-line drugs are paracetamol (acetaminophen) and a non-steroidal anti-inflammatory like ibuprofen, scheduled at fixed intervals starting on the day of surgery. Local anaesthetic blocks (TAP block, bupivacaine at the incision) handle the most painful early window. Opioids are reserved for breakthrough pain only.
The multimodal analgesia ladder
-
1
Paracetamol 1000mg every 6 hours, scheduled
Started on the day of surgery (POD 0). Maximum 4000mg per 24 hours from all sources. Works centrally to block pain perception.
-
2
Ibuprofen 400-800mg every 6 hours, scheduled
Started on POD 1. Works peripherally at the inflammation site. Combined with paracetamol, the synergism delivers stronger pain control than either alone.
-
3
Local anaesthetic at incision (TAP block, bupivacaine)
Bupivacaine 0.25% with epinephrine injected at the incision site, or transversus abdominis plane (TAP) block delivered by the anaesthetist. Numbs the abdominal wall for 12-24 hours, covering the most painful early recovery period.
-
4
Tramadol or oxycodone — backup only
Oxycodone 5-10mg every 4 hours as needed, or tramadol 100mg every 4-6 hours, used only when scheduled paracetamol + ibuprofen are insufficient. Most patients never reach this step.
-
5
Patient-controlled IV opioid — rare
Hydromorphone PCA reserved for patients who require IV opioid more than twice in a 24-hour period despite the above. This is the exception, not the routine.
Dr. Khaled Ghalwash aims to discharge every patient on oral paracetamol and ibuprofen alone. Opioids are not the goal of pain management. The goal is comfort that does not lead to constipation, nausea, dependence, or the next chronic-user statistic. Multimodal analgesia is how the modern surgeon takes pain seriously without taking the patient down a worse road.
Why multimodal beats opioid-first
When NSAIDs are not the right choice
Ibuprofen and other NSAIDs are not for everyone. We modify the protocol for:
- Chronic kidney disease — NSAIDs reduce kidney perfusion. We substitute with paracetamol alone plus regional blocks.
- Active peptic ulcer disease — NSAIDs raise bleeding risk in the upper GI tract.
- Recent cardiovascular event — NSAIDs are avoided for 6 months after MI or stroke.
- Specific anastomoses — concerns about NSAIDs and anastomotic leaks have not been confirmed in modern randomised trials, but we use selective NSAID timing in colorectal anastomosis cases.
What this looks like for you
Most elective surgery patients experience pain in the 2-4 out of 10 range during the first 48 hours under the multimodal protocol. Pain at this level allows walking, eating, sleeping, and conversation. Pain that escalates above 5 prompts the next ladder step. The patient and the team monitor and adjust together.
By discharge, almost all patients are on oral paracetamol + ibuprofen alone, often with a short course of paracetamol-only at home. The medication regimen is written for you, with timing and stopping criteria.
Frequently asked questions
Why doesn't the surgeon give me strong painkillers like morphine?
Multimodal opioid-sparing analgesia is the modern standard: paracetamol 1000mg every 6 hours plus ibuprofen 400-800mg every 6 hours starting day of surgery. Two drugs with different mechanisms control pain better than one strong drug, with fewer side effects (constipation, nausea, dependence). Opioids are reserved for breakthrough pain.
Will I have a lot of pain after the operation?
No. ERAS aims to keep pain manageable on oral medication by the time you leave the hospital. The combination of paracetamol + ibuprofen + local anesthetic blocks (TAP block, bupivacaine at incision) usually keeps pain at 2-4 out of 10 in the first 48 hours, the same range or better than older opioid-heavy regimens.
Are opioids dangerous after surgery?
Yes if used routinely. Studies show 6-10% of opioid-naive patients become chronic opioid users after surgery if discharged on opioid prescriptions. The opioid epidemic in North America was partly fueled by routine post-op opioid prescribing. Multimodal analgesia avoids this entirely.
What is multimodal analgesia?
Combining 2 or more pain medications with different mechanisms of action: paracetamol (works centrally) + NSAID (works at inflammation site) + local anesthetic (blocks nerve signals at incision). The synergism allows lower doses of each, with stronger pain control and fewer side effects.
Can I take ibuprofen after my abdominal surgery?
Yes, ibuprofen 400-800mg every 6 hours starting post-operative day 1 is part of the ERAS analgesic ladder. Concerns about NSAIDs and anastomotic leaks have not been confirmed in modern randomized trials. Patients with kidney problems or peptic ulcer history are exceptions.
What is a TAP block?
Transversus abdominis plane block: an injection of local anesthetic (bupivacaine) into the abdominal wall by the anesthetist before or after surgery. Numbs the abdominal wall for 12-24 hours, reducing the need for opioids during the most painful early recovery period.
What if paracetamol and ibuprofen are not enough?
Tramadol or oxycodone is added as a backup, only when needed. Patient-controlled analgesia (IV opioid pump) is reserved for the rare patient who needs IV doses repeatedly. Most patients never reach this step.
