Association of intraoperative hypotension and cumulative norepinephrine dose with postoperative acute kidney injury in patients having noncardiac surgery: a retrospective cohort analysis.

Background: Intraoperative hypotension is associated with acute kidney injury (AKI). Clinicians thus frequently use vasopressors, such as norepinephrine, to maintain blood pressure. However, vasopressors themselves might promote AKI.

Evaluating the Construct Validity of the Charité Alarm Fatigue Questionnaire using Confirmatory Factor Analysis.

Background: The Charité Alarm Fatigue Questionnaire (CAFQa) is a 9-item questionnaire that aims to standardize how alarm fatigue in nurses and physicians is measured. We previously hypothesized that it has 2 correlated scales, one on the psychosomatic effects of alarm fatigue and the other on staff's coping strategies in working with alarms.

Objective: We aimed to validate the hypothesized structure of the CAFQa and thus underpin the instrument's construct validity.

Persistent use of nitrous oxide for anaesthesia in European hospitals despite its harmfulness to the climate - how emission taxation can achieve the coupling of cost-effectiveness and climate protection: observational study.

Background: Health care has the intrinsic obligation to preserve health. This concept is also applicable to planetary health. Nitrous oxide (NO) lacks clinical indications in modern anaesthesia, while it is a high-potential greenhouse gas.
