Randomized Controlled Trial Multicenter StudyDEX-2-TKA - DEXamethasone twice for pain treatment after Total Knee Arthroplasty. A protocol for a randomized, blinded, three-group multicentre clinical trial.
Multimodal analgesia is considered the leading principle for post-operative pain treatment, but no gold standard after total knee arthroplasty (TKA) exists. ⋯ Recruiting is planned to commence September 2018 and expected to finish March 2020.

Randomized Controlled TrialVolume of ropivacaine 0.2% and sciatic nerve block duration:a randomised, blinded trial inhealthy volunteers.
Sciatic nerve blocks are used for many orthopaedic procedures on the knee, lower leg, foot and ankle. However, as nerve block durations vary considerably, the timing of supplemental analgesia is challenging. Therefore, knowledge on the effect of local anaesthetic (LA) dose on block duration is important to outweigh the benefits of increasing LA dose against the risk of LA systemic toxicity. In this randomized, double-blind trial, we aimed to explore the relationship between the volume of ropivacaine 0.2% and sciatic nerve block duration. We hypothesized that increasing LA volume would prolong block duration. ⋯ We found no effect of increasing the volume of ropivacaine 0.2% from 5 to 30 mL on sensory sciatic nerve block duration.

Randomized Controlled Trial Multicenter StudyBenefits and harm of paracetamol and ibuprofen in combination for postoperative pain: preplanned subgroup analyses of the multicenter randomized PANSAID trial.
The "Paracetamol and Ibuprofen in Combination" (PANSAID) trial showed that combining paracetamol and ibuprofen resulted in lower opioid consumption than each drug alone and we did not find an increase in risk of harm when using ibuprofen vs paracetamol. The aim of this subgroup analysis was to investigate the differences in benefits and harms of the interventions in different subgroups. We hypothesized that the intervention effects would differ in subgroups with different risk of pain or adverse events. ⋯ These pre-planned subgroup analyses did not suggest that patients in the investigated subgroups benefitted differently from a basic non-opioid analgesic regimen consisting of paracetamol and ibuprofen. Further, there was no evidence of subgroup heterogeneity regarding harm and use of ibuprofen. Because of reduced statistical power in subgroup analyses, we cannot exclude clinically relevant subgroup heterogeneity.
