Multicenter Study Comparative Study Clinical Trial Observational Study
Association between tracheostomy timing and outcomes for older critically ill COVID-19 patients: prospective observational study in European intensive care units.
Tracheostomy is performed in patients expected to require prolonged mechanical ventilation, but to date optimal timing of tracheostomy has not been established. The evidence concerning tracheostomy in COVID-19 patients is particularly scarce. We aimed to describe the relationship between early tracheostomy (≤10 days since intubation) and outcomes for patients with COVID-19. ⋯ ClinicalTrials.gov NCT04321265.

Describe a series of patients who developed naloxone-associated pulmonary edema after recreational opioid use. ⋯ Severe acute pulmonary edema may follow naloxone administration after recreational opioid overdose. Acute care clinicians should be aware of this potentially life-threatening adverse effect of naloxone.

The cuff leak test (CLT) has been shown to have excellent specificity and moderate sensitivity for predicting postextubation stridor (PES). However, the ventilator flow waveform and the subject position are not uniform in current clinical practice. ⋯ In this study, performing the CLT with the subject in semi-recumbent position using the square waveform appeared to allow for the best prediction of PES.

Perioperative hypersensitivity reactions may be difficult to diagnose during general anesthesia. Postinduction hypotension is the most common sign but is not specific. It was recently suggested that low end-tidal carbon dioxide (ETco2) might be a marker of anaphylaxis (Ring and Messmer grades III to IV immediate hypersensitivity reactions) in hypotensive patients under mechanical ventilation. To test this hypothesis, the authors compared ETco2 in patients with a diagnosis of anaphylaxis and in patients with severe hypotension from any other cause after the induction of anesthesia. ⋯ In case of severe hypotension after anesthesia induction, a low ETco2 contributes to the diagnosis of anaphylaxis, in addition to the classical signs of perioperative immediate hypersensitivity.

Successful extubation is difficult to predict. Ultrasound measurement of the diaphragm thickening fraction (DTF) might help predict weaning failure after cardiothoracic surgery. ⋯ U1111-1180-1999.
