Randomized Controlled Trial Multicenter StudySpontaneous breathing trials should be adapted for each patient according to the critical illness. A new individualised approach: the GLOBAL WEAN study.
Spontaneous breathing trials (SBT) evaluate the patient's capacity to maintain inspiratory effort after extubation. SBT practices are heterogeneous and not individualised. The objective of this study was to assess which SBT best reproduces inspiratory effort after extubation in five critical illnesses. ⋯ Unassisted SBTs, namely PSV0PEEP0 and T-piece trial, are the most appropriate to replicate the postextubation effort to breathe.

Randomized Controlled Trial Comparative StudyComparing the hemodynamic effects of ketamine versus fentanyl bolus in patients with septic shock: a randomized controlled trial.
Ketamine and fentanyl are commonly used for sedation and induction of anesthesia in critically ill patients. This study aimed to compare the hemodynamic effects of ketamine versus fentanyl bolus in patients with septic shock. ⋯ gov Identifier: NCT05957302. URL: https://clinicaltrials.gov/study/NCT05957302 .

Association Between Early Hyperoxemia Exposure and Intensive Care Unit Mortality in Intracerebral Hemorrhage: An Observational Cohort Analysis.
Supraphysiologic levels of oxygen could have potential adverse effects on the brain that may be dose and time dependent in patients with brain injury. We therefore aimed to assess whether exposure to excess supplemental oxygen, measured as time-weighted mean exposure to hyperoxemia, was associated with intensive care unit (ICU) mortality in patients with intracerebral hemorrhage (ICH). ⋯ In patients with ICH admitted to the ICU, we observed an association between hyperoxemia dose and ICU mortality. Further prospective study is required to inform guidance on early systemic oxygen targets in ICH.

Cardiogenic shock (CS) presents a medical challenge with limited treatment options. Positive end-expiratory pressure (PEEP) during mechanical ventilation has been linked with clinical benefits in patients with CS. This study investigated whether increasing PEEP levels could unload the left ventricle (LV) in CS in a large animal model of LV-CS. ⋯ Applying higher PEEP levels reduced pressure-volume area, preserving CO while decreasing mean arterial pressure. Positive end-expiratory pressure could be a viable LV unloading strategy if titrated optimally during LV-CS.
