Randomized Controlled Trial Multicenter StudyAnesthesiologists' skills in emergency cricothyroidotomy mandate a brush-up training after 3 months-A randomized controlled trial.
In the Difficult Airway Society's 2015 "cannot intubate, cannot oxygenate" guideline, the emergency cricothyroidotomy is the final option when managing an unanticipated difficult airway. How often training for maintenance of this skill is required for anesthesiologists remains unknown. We aimed to assess if specialist-trained anesthesiologists' skills improved from a brush-up intervention and if skills were retained after 3 months. ⋯ Exposure to simulation-based brush-up training in emergency cricothyroidotomy improved anesthesiologists' technical performance and was overall retained after 3 months. Some loss of skill concerning specific items was observed, highlighting the need for regular training in emergency cricothyroidotomy. Simulation-based training should be prioritized to improve and maintain technical skills in infrequent high-stakes procedures.

Multicenter StudyPre-oxygenation using high-flow nasal oxygen in parturients undergoing caesarean section in general anaesthesia: A prospective, multi-centre, pilot study.
Parturients undergoing caesarean section in general anaesthesia have an increased risk of desaturating during anaesthesia induction. Pre- and peri-oxygenation with high-flow nasal oxygen prolong the safe apnoea time but data on parturients undergoing caesarean section under general anaesthesia are limited. This pilot study aimed to investigate the clinical effects and frequency of desaturation in parturients undergoing caesarean section in general anaesthesia pre- and peri-oxygenated with high-flow nasal oxygen and compare this to traditional pre-oxygenation using a facemask. ⋯ Pre- and peri-oxygenation with high-flow nasal oxygen maintain adequate oxygen saturation levels during induction of anaesthesia also in parturients. Regurgitation of gastric content did not occur in any parturient and no other safety concerns were observed in this pilot study.

Multicenter StudyAbnormal serum levels of magnesium, phosphate, and zinc in ICU patients-Characteristics, management, and outcomes: The WhyTrace cohort study.
Abnormal serum levels of magnesium, phosphate, and zinc appear common in intensive care unit (ICU) patients, but the epidemiology, management, and associations with outcomes are less well described. We described these factors and estimated associations with outcomes in a large dataset of Danish ICU patients. ⋯ In this multicenter cohort study of acutely admitted ICU patients, most experienced low serum levels of magnesium, phosphate, or zinc during ICU stay, many received supplementation, and experiencing both low and high serum levels during ICU stay was not uncommon. Associations between serum levels and clinical outcomes appeared inconclusive because the data proved unfit for these analyses.

Randomized Controlled Trial Multicenter StudyGoal-directed fluid removal with furosemide versus placebo in intensive care patients with fluid overload: a randomised, blinded trial (GODIF trial - first version).
Salt and water accumulation leading to fluid overload is associated with increased mortality in intensive care unit (ICU) patients, but diuretics' effects on patient outcomes are uncertain. In this first version of the GODIF trial, we aimed to assess the effects of goal-directed fluid removal with furosemide versus placebo in adult ICU patients with fluid overload. ⋯ The use of cumulative fluid balance as the only estimate of fluid status appeared too difficult to use in clinical practice. We were unable to provide precise estimates for any outcomes as only 4.1% of the planned sample size was randomised.

Multicenter StudyIntra-operative blood transfusion in elderly patients on antithrombotic therapy.
Many elderly patients are receiving antithrombotics, which may increase intra-operative blood loss. We aimed to assess whether chronic antithrombotic therapy was associated with intra-operative transfusion of packed red blood cells in patients at least 80 years of age undergoing elective procedures. ⋯ A total of 7174 patients were included of whom 4073 (56.8%) were on antithrombotic therapy. Among patients on antithrombotic therapy 191 (4.7%) received intra-operative blood transfusion compared with 98 (3.2%) of patients not on chronic antithrombotic therapy (crude odds ratio: 1.51, 95% CI 1.18-1.94). Following multiple logistic regression analysis, the adjusted odds ratio was 0.98; 0.73-1.32. We found that chronic antithrombotic therapy was associated with intra-operative transfusion of packed red blood cells in elderly patients undergoing elective procedures in an unadjusted analysis, but not in a multivariate adjusted model.
