Invasive mechanical ventilation is a key supportive therapy for patients on intensive care. There is increasing emphasis on personalised ventilation strategies. Clinical decision support systems (CDSS) have been developed to support this. ⋯ A coordinated approach grounded in implementation science is required to support CDSS implementation. Future research should describe factors that guide clinical decision-making throughout mechanical ventilation, with and without CDSS, map clinical workflow, and devise implementation toolkits. Novel research design analogous to a learning organisation, that considers the commercial aspects of device design, is required.

Major surgery is associated with high complication rates. Several risk scores exist to assess individual patient risk before surgery but have limited precision. Novel prognostic factors can be included as additional building blocks in existing prediction models. A candidate prognostic factor, measured by cardiopulmonary exercise testing, is ventilatory efficiency (VE/VCO2). The aim of this systematic review was to summarise evidence regarding VE/VCO2 as a prognostic factor for postoperative complications in patients undergoing major surgery. ⋯ PROSPERO (CRD42022369944).

The elements that render anaesthesia a captivating profession can also foster stress and fatigue. Professionals considering anaesthesia as a career choice should have a comprehensive understanding of the negative consequences of fatigue and its implications for clinical performance and of the available preventive measures. Available evidence suggests that factors unrelated to patient characteristics or condition can affect clinical outcomes where anaesthetists are involved. ⋯ Fatigue seems to negatively affect both physical and mental health of anaesthetists. Existing evidence justifies specific interventions by institutions, stakeholders, and scientific societies to address the effects of anaesthetist fatigue. This narrative review summarises current knowledge regarding the effects of fatigue on anaesthetist well-being and patient safety, and discusses potential preventive solutions.

Randomized Controlled Trial
Hypotension after general anaesthesia induction using remimazolam or propofol in geriatric patients undergoing sevoflurane anaesthesia with remifentanil: a single-centre, double-blind, randomised controlled trial.
The occurrence of hypotension after induction of general anaesthesia is common in geriatric patients, and should be prevented to minimise perioperative complications. Compared with propofol, remimazolam potentially has a lower incidence of hypotension. This study aimed to compare the incidence of hypotension after general anaesthesia induction with remimazolam or propofol in geriatric patients. ⋯ UMIN000042587.

Multicenter Study
Development and validation of the Ex-Care BR model: a multicentre initiative for identifying Brazilian surgical patients at risk of 30-day in-hospital mortality.
Surgical risk stratification is crucial for enhancing perioperative assistance and allocating resources efficiently. However, existing models may not capture the complexity of surgical care in Brazil. Using data from various healthcare settings nationwide, we developed a new risk model for 30-day in-hospital mortality (the Ex-Care BR model). ⋯ NCT05796024.
