Randomized Controlled Trial Multicenter Study
Cardiovascular events in patients undergoing hip fracture surgery treated with remote ischaemic preconditioning: 1-year follow-up of a randomised clinical trial.
Remote ischaemic preconditioning reduces the risk of myocardial injury within 4 days of hip fracture surgery. We aimed to investigate the effect of remote ischaemic preconditioning on the incidence of major adverse cardiovascular events 1 year after hip fracture surgery. We performed a phase-2, multicentre, randomised, observer-blinded, clinical trial between February 2015 and September 2017. ⋯ Fewer patients in the remote ischaemic preconditioning group had a myocardial infarction (11 (3.5%) vs. 22 (7.1%); hazard ratio (95%CI) 0.48 (CI 0.23-1.00); p = 0.04). Remote ischaemic preconditioning did not reduce the occurrence of major adverse cardiovascular events within 1 year of hip fracture surgery. The effect of remote ischaemic preconditioning on clinical cardiovascular outcomes in non-cardiac surgery needs confirmation in appropriately powered randomised clinical trials.

Case reports have fulfilled an important role in the development of anaesthesia and continue to be highly relevant to modern practice. Despite this, they are sometimes criticised for being insufficiently rigorous to meaningfully inform clinical practice or research design. Reporting checklists are a useful tool to improve rigour in research and, although case report checklists have previously been developed, no existing checklist focuses on the peri-operative setting. ⋯ Adopting a standardised approach to the content of case reports presents clear benefits to authors, editors and peer reviewers through streamlining the processes involved in writing and publication. The Anaesthesia Case Report checklist provides a pragmatic framework for comprehensive and transparent reporting. We hope it will facilitate the authorship of high-quality case reports with the potential to further improve the quality and safety of peri-operative care.

Review Meta Analysis
The association between post-dural puncture headache and needle type during spinal anaesthesia: a systematic review and network meta-analysis.
Post-dural puncture headache is one of the most undesirable complications of spinal anaesthesia. Previous pairwise meta-analyses have either compared groups of needles or ranked individual needles based on the pooled incidence of post-dural puncture headache. These analyses have suggested both the gauge and needle tip design as risk-factors, but failed to provide an unbiased comparison of individual needles. ⋯ Meta-regression by type of surgical population (obstetric/non-obstetric) and participant position (sitting/lateral) did not alter these rank orders. This analysis provides an unbiased comparison of individual needles that does not support the use of simple rules when selecting the optimal needle. The 26-G atraumatic needle is most likely to enable successful insertion while avoiding post-dural puncture headache but, where this is not available, our probability rankings can help clinicians select the best of available options.
