Tramadol for Acute Postoperative Pain After Hip Replacement Surgery

Introduction to Tramadol Use

The American Society of Anesthesiologists recommends tramadol as a rescue analgesic only after optimized multimodal analgesia with paracetamol and NSAIDs, used with caution in patients with renal dysfunction, and limited to no more than 5-7 days duration 1, 2, 3

The British Journal of Anaesthesia suggests paracetamol combined with NSAIDs or COX-2 inhibitors forms the cornerstone of postoperative analgesia after hip replacement and should be administered pre-operatively or intra-operatively and continued postoperatively 4
A single intraoperative dose of dexamethasone 8-10 mg provides analgesic and anti-emetic benefits 4
Regional anesthesia techniques (fascia iliaca block or local infiltration analgesia) are recommended, especially in patients with contraindications to basic analgesics or high expected postoperative pain 4

Tramadol should be used with extreme caution in patients with renal dysfunction - both dose and frequency should be reduced (e.g., halved) 1
Oral opioids including tramadol should be avoided in patients with renal impairment 1
Prescribe no more than 5-7 days of tramadol at discharge 2, 3, 7
If a patient is still taking tramadol 90 days after surgery, this should trigger further assessment for persistent pain after surgery or referral to pain services 2, 3, 7

One procedure-specific systematic review for total hip arthroplasty found that oral tramadol 50 or 100 mg was not significantly different from placebo for postoperative pain scores 6

Optimize multimodal analgesia first with paracetamol + NSAID/COX-2 inhibitor 5
Dexamethasone 8-10 mg intraoperatively 5
Regional anesthesia if feasible 5
Assess renal function and avoid tramadol or reduce dose by 50% if renal dysfunction is present 1
Provide no more than 5-7 days supply of tramadol 2, 3, 7

Stronger opioids (morphine, fentanyl) with appropriate monitoring are reasonable alternatives if tramadol is contraindicated or ineffective 1, 5
Patient-controlled analgesia (PCA) with stronger opioids may be more appropriate for severe pain 5
Consider consultation with pain services for complex cases 2, 3
