Observational StudyBeta-lactam antibiotic concentrations in critically ill patients with standard and adjusted dosages: A prospective observational study.
Antibiotic concentration target attainment is known to be poor in critically ill patients. Dose adjustment is recommended in patients with altered clearance, obesity and those with bacterial species with intermediate susceptibility. The aim of this study was to investigate the variation of antibiotic concentration in critically ill patients with standard or adjusted dosing regimens. ⋯ Beta-lactam antibiotics concentration vary widely in critically ill patients. The current standard dosing regimens employed during the study were not sufficient to reach 100% ƒT > MIC in approximately a quarter of the patients. In patients where dose adjustment was performed, the group with increased dose also had low target attainment, as opposed to patients with dose reduction, who all reached target. This suggests the need for further individualization of dosing where therapeutic drug monitoring can be an alternative to further increase target attainment.

Review Practice Guideline Meta AnalysisAwake proning in patients with COVID-19-related hypoxemic acute respiratory failure: Endorsement by the Scandinavian Society of Anaesthesiology and Intensive Care Medicine.
Awake proning in spontaneously breathing patients with hypoxemic acute respiratory failure was applied during the coronavirus disease 2019 (COVID-19) pandemic to improve oxygenation while avoiding tracheal intubation. An updated systematic review and meta-analysis on the topic was published. ⋯ The SSAI CPC endorses the clinical practice guideline "Awake proning in patients with COVID-19-related hypoxemic acute respiratory failure: A rapid practice guideline". This guideline serves as a useful decision aid for clinicians caring for critically ill patients with COVID-19-related acute hypoxemic respiratory failure and can be used to provide guidance on use of prone positioning in this group of patients.

Multicenter StudyCentral venous catheter tip misplacement: A multicentre cohort study of 8556 thoracocervical central venous catheterisations.
There is a paucity of data on the incidence of central venous catheter tip misplacements after the implementation of ultrasound guidance during insertion. The aims of the present study were to determine the incidence of tip misplacements and to identify independent variables associated with tip misplacement. ⋯ In this large prospective multicentre cohort study, performed in the ultrasound-guided era, we demonstrated the incidence of tip misplacements to be 3.7 (3.3-4.1)%. Right internal jugular vein catheterisation had the lowest incidence of both minor and major tip misplacement.

Pre-oxygenation using high-flow nasal oxygen versus tight facemask in trauma patients undergoing emergency anaesthesia.
Patients suffering from major traumatic injuries frequently require emergency anaesthesia. Due to often compromised physiology and the time-sensitive management, trauma patients may be more prone to desaturate during induction of anaesthesia. We hypothesised that pre-oxygenation using high-flow nasal oxygen would decrease the risk of desaturation during induction of anaesthesia in trauma patients and the study therefore aimed to compare the frequency of desaturation when pre-oxygenation was performed with high-flow nasal oxygen or a traditional facemask. ⋯ In this prospective study investigating trauma patients undergoing emergency anaesthesia, we could not see any difference in the number of patients desaturating when pre-oxygenation was performed with high-flow nasal oxygen compared to a tight-fitting facemask. Pre-oxygenation using high-flow nasal oxygen was assessed as easier compared to facemask pre-oxygenation.

Associations of dexamethasone's effect on morphine consumption after total knee arthroplasty-Subgroup analyses.
The DEXamethasone twice for pain treatment after Total Knee Arthroplasty (DEX-2-TKA) trial showed that adding one and two doses of 24 mg intravenous dexamethasone to paracetamol, ibuprofen and local infiltration analgesia, reduced morphine consumption (primary outcome) within 48 h after TKA. We aimed to explore the differences in the effect of dexamethasone on morphine consumption in different subgroups. Quantile regression adjusted for site was used to test for significant interaction between the predefined dichotomised subgroups and treatment group. ⋯ Our results from the quantile regression analyses indicate that the male sex and younger age (≤65 years) may be associated with a larger analgesic effect of dexamethasone than the effects in other types of patients. However, this is not supported by post-hoc multivariate linear regression analyses. The two types of analyses both supported a possible interaction with the type of anaesthesia.
