Observational Study
Gastric pressure monitoring unveils abnormal patient-ventilator interaction related to active expiration: a retrospective observational study.
Patient-ventilator dyssynchrony is frequently observed during assisted mechanical ventilation. However, the effects of expiratory muscle contraction on patient-ventilator interaction are underexplored. The authors hypothesized that active expiration would affect patient-ventilator interaction and they tested their hypothesis in a mixed cohort of invasively ventilated patients with spontaneous breathing activity. ⋯ Active expiration can impair patient-ventilator interaction in critically ill patients. Without documenting gastric pressure, abnormal patient-ventilator interaction associated with expiratory muscle contraction may be mistakenly attributed to a mismatch between the patient's inspiratory effort and mechanical inflation. This misinterpretation could potentially influence decisions regarding clinical management.

Tracheal Intubation and Mechanical Ventilation in Adults with Severe Salicylate Poisoning.
Salicylate poisoning may lead to critical acid-base disturbances. Tracheal intubation and mechanical ventilation for patients with severe salicylism has been strongly discouraged. ⋯ In our single-center experience managing adults with severe salicylate poisoning, tracheal intubation and mechanical ventilation were not associated with substantial perturbation of serum pH or severe complications. These findings challenge the current paradigm that these interventions should be avoided in salicylate-poisoned patients.

Atrial fibrillation (AF) is a common arrhythmia in patients at high cardiovascular risk. COVID-19 patients with underlying cardiovascular disease are at increased risk of poor clinical outcomes. In this study, we aimed to determine hospital outcomes among patients admitted with AF and COVID-19 infection. ⋯ COVID-19 hospitalized patients frequently have underlying AF, which confers a higher risk of adverse hospital outcomes and mortality, even after adjusting for baseline comorbidities. Heightened awareness is needed in the treatment of hospitalized COVID-19 patients with AF.

Persistent shortcomings of invasive positive pressure ventilation make it less than an ideal intervention. Over the course of more than seven decades, clinical experience and scientific investigation have helped define its range of hazards and limitations. ⋯ Trending analysis, timely interventions, and closer communication with the caregiver would limit adverse clinical trajectories. Judging from the rapid progress of recent years, we are encouraged to think that insights from physiologic research and emerging technological capability may eventually address important aspects of current deficiencies.

Ketamine Analgo-sedation for Mechanically Ventilated Critically Ill Adults: A Rapid Practice Guideline from the Saudi Critical Care Society and the Scandinavian Society of Anesthesiology and Intensive Care Medicine.
This Rapid Practice Guideline (RPG) aimed to provide evidence‑based recommendations for ketamine analgo-sedation (monotherapy and adjunct) versus non-ketamine sedatives or usual care in adult intensive care unit (ICU) patients on invasive mechanical ventilation (iMV) and to identify knowledge gaps for future research. ⋯ The RPG panel provided two conditional recommendations and suggested (1) against using ketamine as monotherapy analgo-sedation in critically ill adults on iMV when other analgo-sedatives are available; and (2) using ketamine as an adjunct to non-ketamine usual care sedatives (e.g., opioids, propofol, dexmedetomidine) or continuing with non-ketamine usual care sedatives alone. Large-scale trials should provide additional evidence.
