Tramadol-paracetamol for postoperative pain after spine surgery - A randomized, double-blind, placebo-controlled study.

OBJECTIVES: Multimodal pain management is one component in enhanced recovery after surgery protocol. Here we evaluate the efficacy of tramadol-paracetamol in acute postoperative pain and pain outcome at 12 months after spine surgery in randomized, double-blind, placebo-controlled trial. METHODS: We randomized 120 patients undergoing spine surgery to receive, for add-on pain management, two tramadol-paracetamol 37.5 mg/325 mg (n = 61) or placebo tablets (n = 59) twice a day for 5 postoperative days. In the hospital, multimodal pain management consisted of dexketoprofen and oxycodone. After discharge, patients were prescribed ibuprofen 200 mg, maximum 1,200 mg/day. Pain, analgesic use, and satisfaction with pain medication were followed up with the Brief Pain Inventory questionnaire before surgery and at 1 and 52 weeks after surgery. The primary outcome was patients' satisfaction with pain medication 1 week after surgery. RESULTS: At 1 week after surgery, patients' satisfaction with pain medication was similarly high in the two groups, 75% [interquartile range, 30%] in the placebo group and 70% [40%] in the tramadol-paracetamol group (p = 0.949) on a scale: 0% = not satisfied, 100% = totally satisfied. At 1 week, ibuprofen dose was lower in the placebo group 200 mg [1,000] compared to the tramadol-paracetamol group, 800 mg [1,600] (p = 0.016). There was no difference in the need for rescue oxycodone. Patients in the tramadol-paracetamol group had more adverse events associated with analgesics during the first postoperative week (relative risk = 1.8, 95% confidence interval, 1.2-2.6). CONCLUSION: Add-on pain treatment with tramadol-paracetamol did not enhance patients' satisfaction with early pain management after back surgery.

Postoperative pain in a prospectively assessed surgical short-stay cohort: A subgroup analysis.

BACKGROUND: There is sparse information about postoperative pain after short stay surgery. We explored the incidence of immediate postoperative pain and its relationship with persistent pain or opioid use 2 weeks after surgery. METHODS: This was a subgroup analysis of prospective and controlled data from adult patients (n = 931) who underwent short-stay surgery in a tertiary care hospital. Data comprised patient demographics, surgical category, pain scores and analgesic management during the recovery unit stay, before discharge on the postoperative morning after surgery and again 2 weeks after surgery. RESULTS: Half of the patients had severe dynamic pain in the recovery unit. It was commonest after orthopaedic (70% of patients), followed by gynaecological (54%), gastrointestinal (51%) and spine surgery (49%). Multimodal pain management was used for most patients (n = 811, 87%) with opioid use predominant. The median oxycodone dose during short-stay was the highest after orthopaedic surgery (39 mg). The first individual dynamic pain score after surgery was associated with follow-up pain score at rest (OR = 1.37), dynamic pain (OR = 1.35) and pain interference (OR = 1.34) at 2 weeks after surgery. Maximum dynamic pain reported in the recovery unit was associated with pain at rest (OR = 1.56), dynamic pain (OR = 1.65) and pain interference (OR = 1.45) at 2 weeks after surgery. Pain scores at 2 weeks were highest and analgesic use greatest in those patients who underwent spinal surgery. CONCLUSIONS: Intense postoperative pain remains common after short-stay surgery in some surgical categories including orthopaedic surgery and is associated with a greater likelihood of pain at 2 weeks.
