Multicenter Study Observational StudyThoracic Paravertebral Nerve Blocks in Pediatric Patients: Safety and Clinical Experience.
Thoracic paravertebral nerve blocks (PVNBs) provide excellent analgesia for many surgeries. The primary aim was to estimate the complication rate, and secondary aims were to provide information on the potential clinical application of PVNBs. Data on 2390 PVNBs were collected. ⋯ There was 1 case of local anesthetic systemic toxicity for a major complication rate of 1 per 2390 PVNBs. The minor complication rate was 13.2%. We demonstrate a low risk of complications in pediatric patients receiving PVNBs for various surgeries.

Multicenter Study Pragmatic Clinical Trial
Regional versus General Anesthesia for Promoting Independence after Hip Fracture (REGAIN): protocol for a pragmatic, international multicentre trial.
Hip fractures occur 1.6 million times each year worldwide, with substantial associated mortality and losses of independence. At present, anaesthesia care for hip fracture surgery varies widely within and between countries, with general anaesthesia and spinal anaesthesia representing the 2 most common approaches. Limited randomised evidence exists regarding potential short-term or long-term differences in outcomes between patients receiving spinal or general anaesthesia for hip fracture surgery. ⋯ The REGAIN trial has been approved by the ethics boards of all participating sites. Recruitment began in February 2016 and will continue until the end of 2019. Dissemination plans include presentations at scientific conferences, scientific publications, stakeholder engagement efforts and presentation to the public via lay media outlets.

Randomized Controlled Trial Multicenter Study
A Randomized, Multicenter, Double-Blind Study of Local Infiltration Analgesia with Liposomal Bupivacaine for Postsurgical Pain Following Total Knee Arthroplasty: Rationale and Design of the Pillar Trial.
Liposomal bupivacaine, a prolonged-release formulation of bupivacaine hydrochloride, is indicated for infiltration into the surgical site for postsurgical analgesia. Results from previous total knee arthroplasty (TKA) studies suggest that analgesic efficacy associated with liposomal bupivacaine may be impacted by variability in infiltration technique. The PILLAR study is designed to assess liposomal bupivacaine efficacy in TKA using a standardized infiltration protocol. Materials and Methods/Design: This phase 4, multicenter, randomized, double-blind, controlled, parallel-group study will compare the safety and efficacy of infiltration with liposomal bupivacaine versus standard bupivacaine for postsurgical pain control in adults undergoing primary unilateral TKA. All subjects will receive a standardized pre-surgical analgesic regimen, and will be randomized to receive either liposomal bupivacaine 266 mg/20 mL (admixed with standard bupivacaine 0.5% 20 mL and expanded to a total volume of 120 mL) or bupivacaine 0.5% 20 mL (expanded to a total volume of 120 mL). The study drug will be infiltrated using six syringes (prefilled with 20 mL of study drug solution) to deliver 1-1.5 mL infusions into prespecified periarticular tissues. All subjects will receive standardized postsurgical analgesia and access to rescue medication. The co-primary efficacy endpoints are area under the curve of visual analog scale pain intensity scores from 12-48 hours postsurgery and total postsurgical opioid consumption from 0-48 hours. Secondary efficacy endpoints include other pain assessments, time to first use of rescue medication, discharge readiness, use of skilled nursing facilities, and hospital length of stay. Safety will be evaluated based on adverse events. ⋯ The use of a standardized protocol comparing infiltration of equal volumes of the study drug, designed by experienced investigators to ensure complete coverage of all areas innervating the surgical site while minimizing leakage of study drug, will help define the role of liposomal bupivacaine in the setting of TKA.

Randomized Controlled Trial Multicenter StudySevoflurane Versus Total Intravenous Anesthesia for Isolated Coronary Artery Bypass Surgery with Cardiopulmonary Bypass: A Randomized Trial.
Several studies have suggested that the cardioprotective effects of halogenated anesthetics in cardiac surgery result in reduced cardiac biomarker release compared with total intravenous anesthesia (TIVA). These findings came from relatively small randomized clinical trials and meta-analyses. The authors of this study hypothesized that the beneficial effects of volatile anesthetics translate into a reduced length of hospital stay after coronary artery bypass grafting surgery (CABG) with cardiopulmonary bypass. ⋯ Anesthesia with sevoflurane reduced cardiac biomarker release and length of hospital stay after CABG with cardiopulmonary bypass surgery compared with propofol-based TIVA with a possible reduction in 1-year mortality.

Randomized Controlled Trial Multicenter StudyContinuous wound infiltration versus epidural analgesia after hepato-pancreato-biliary surgery (POP-UP): a randomised controlled, open-label, non-inferiority trial.
Epidural analgesia is the international standard for pain treatment in abdominal surgery. Although some studies have advocated continuous wound infiltration with local anaesthetics, robust evidence is lacking, especially on patient-reported outcome measures. We aimed to determine the effectiveness of continuous wound infiltration in hepato-pancreato-biliary surgery. ⋯ Academic Medical Centre, Amsterdam, Netherlands.
