Article Synopsis
  • - Ventilator-associated pneumonia (VAP) is common in cardiac arrest patients, but diagnosing it post-arrest is difficult, leading to debate over the effectiveness of biomarkers like C-reactive protein (CRP) and procalcitonin (PCT) for this purpose.
  • - The study analyzed the role of various biomarkers in diagnosing and predicting VAP within 48 hours following cardiac arrest and therapeutic hypothermia, using a randomized clinical trial as a foundation.
  • - Results showed that VAP patients had distinct clinical features and higher biomarker levels indicating VAP; CRP was notably associated with VAP, demonstrating an area under the curve (AUC) greater than 0.70 in analyses.

Introduction: Current guidelines on clinical nutrition of ventilated patients in the intensive care unit (ICU) recommend initiating continuous enteral nutrition within 48 hours of ICU admission when feasible. However, discontinuous feeding regimens, alternating feeding and fasting intervals, may have an impact on clinical and patient centred outcomes. The ongoing "Impact of daily cyclic enteral nutrition versus standard continuous enteral nutrition in critically ill patients" (DC-SCENIC) trial aims to compare standard continuous enteral feeding with daily cyclic enteral feeding over 10 hours to evaluate if implementing a fasting-mimicking diet can decrease organ failure in ventilated patients during the acute phase of ICU management.

Article Synopsis
  • The PREOPTI-DAM study investigated the effectiveness of high-flow nasal cannula (HFNC) versus facemask for preoxygenation in patients with anticipated difficult airway management, finding no significant difference in oxygen desaturation rates during intubation between the two methods.
  • The study enrolled 186 patients who were randomly assigned to either HFNC or facemask groups, with the primary outcome being oxygen desaturation or the need for bag-mask ventilation.
  • Results showed that while incidence rates for complications were similar, patients using HFNC reported better intubation experiences compared to those using facemasks, indicating a potential benefit for HFNC in difficult airway management scenarios.

Background: Spontaneous-breathing trials can be performed with the use of either pressure-support ventilation (PSV) or a T-piece. Whether PSV trials may result in a shorter time to tracheal extubation than T-piece trials, without resulting in a higher risk of reintubation, among patients who have a high risk of extubation failure is unknown.

Methods: In this multicenter, open-label trial, we randomly assigned patients who had a high risk of extubation failure (i.

Objectives: Individualizing a target mean arterial pressure is challenging during the initial resuscitation of patients with septic shock. The Sepsis and Mean Arterial Pressure (SEPSISPAM) trial suggested that targeting high mean arterial pressure might reduce the occurrence of acute kidney injury among those included patients with a past history of chronic hypertension. We investigated whether the class of antihypertensive medications used before the ICU stay in chronic hypertensive patients was associated with the severity of acute kidney injury occurring after inclusion, according to mean arterial pressure target.
