Comparative efficacy of anaesthetic methods for closed reduction of paediatric forearm fractures: a systematic review.

Background: Forearm fractures in children often require closed reduction in the emergency setting. The choice of anaesthesia influences the degree of pain relief, which determines the success of reduction. Main methods of anaesthesia include procedural sedation and analgesia, haematoma block, intravenous regional anaesthesia (IVRA) and regional nerve blocks.

Impact of Cardiac Arrest Centers on the Survival of Patients With Nontraumatic Out-of-Hospital Cardiac Arrest: A Systematic Review and Meta-Analysis.

Background The role of cardiac arrest centers (CACs) in out-of-hospital cardiac arrest care systems is continuously evolving. Interpretation of existing literature is limited by heterogeneity in CAC characteristics and types of patients transported to CACs. This study assesses the impact of CACs on survival in out-of-hospital cardiac arrest according to varying definitions of CAC and prespecified subgroups.
