Editorial Randomized Controlled Trial
Critical appraisal of randomised trials assessing regional analgesic interventions for knee arthroplasty: implications for postoperative pain guidelines development.
Guidelines are increasingly being used for clinical decision-making. Such guidelines are usually based on meta-analyses, which are generally derived from RCTs. ⋯ Analyses of RCTs assessing analgesic efficacy of advanced regional analgesic techniques in knee arthroplasty show that the majority of trials do not include a package of basic analgesics such as paracetamol, NSAIDs or cyclooxygenase-2 specific inhibitors, dexamethasone, and local infiltration analgesia in the comparator group. Consequently, the current approach to analyse meta-analyses of pain interventions is not optimal, and may lead to inadequate or inappropriate conclusions and clinical guidance.

Randomized Controlled Trial Multicenter Study
Intraoperative lidocaine infusion in patients undergoing pancreatectomy for pancreatic cancer: a mechanistic, multicentre randomised clinical trial.
Intravenous lidocaine has been postulated to improve long-term survival after surgery for pancreatic cancer through anti-inflammatory effects, anti-tumour effects, or both. We investigated whether intraoperative lidocaine improves survival after pancreatectomy for pancreatic cancer and whether lidocaine modified the formation of neutrophil extracellular traps (NETs), high levels of which are associated with poor prognosis. ⋯ NCT03245346; updated in Chi-CTR-2000035469.
