Aim: The aim of our study was to identify predictors for prolonged ICU stay following elective adult cardiac surgery under cardiopulmonary bypass.
Patients And Methods: A retrospective study was conducted during 5 years and a half period. Were included, patients age≥18 years old, underwent elective cardiac surgery under cardiopulmonary bypass. Patients who died within 48hours of surgery were excluded. Prolonged ICU stay was defined as stay in the ICU for 48hours or more.
Results: During the review period, 610 patients were included. One hundred and sixty-four patients have required a prolonged ICU stay (26.9 %). In multivariate analysis, 5 predictors were identified: ejection fraction<30 % (OR 19.991, IC 95 % [1.382-289.1], P=0.028], pulmonary hypertension (OR 2.293, IC 95 % [1.058-4.973], P=0.036), prolonged ventilation (≥12hours) (OR 4.026, IC 95 % [2.407-6.733], P<0.001). Number of blood units transfused (OR 1.568, IC 95 % [1.073-2.291], and postoperative acute renal failure (OR 2.620, IC 95 % [1.026-6.690], P=0.044]. Prolonged ICU stay is significantly associated with prolonged hospital stay (17 days vs 13 days ; P<0.001) and higher in hospital mortality (22 % vs. 3 %, P<0.001).
Conclusion: The identification of these patients at risk of prolonged ICU stay is crucial. It will aid to plan prophylactic measures to optimize their support.

Prolonged Preservation of up to 24h at 10°C does not Impact Outcomes after Lung Transplantation.

Objective: To determine the impact of prolonged storage of donor lungs at 10°C of up to 24h on outcome after lung transplantation.
Background: An increasing body of evidence suggests 10°C as the optimal storage temperature for donor lungs. A recent study showed that cold ischemic times can be safely expanded to >12h when lungs are stored at 10°C.

Background: Delirium is a common complication in patients at the intensive care unit (ICU) and is associated with prolonged ICU-stay and hospitalization and with increased morbidity. The impact of ICU-delirium on long-term survival is not clearly understood.
Methods: This retrospective single center observational study was conducted at the Institute of Intensive Care Medicine at the University Hospital Zurich, Switzerland.

Background: Bacterial pulmonary superinfections develop in a substantial proportion of mechanically ventilated COVID-19 patients and are associated with prolonged mechanical ventilation requirements and an increased mortality. Albeit recommended, evidence supporting the use of empirical antibiotics at intubation is weak and of low quality. The aim of this study was to elucidate the effect of empirical antibiotics, administered within 24hours of endotracheal intubation, on superinfections, duration of mechanical ventilation, and mortality in mechanically ventilated patients with COVID-19.

Introduction And Objectives: Nil by mouth (NBM) is a frequent imposition for patients recovering from critical illness. Its impact on patients' wellbeing and rehabilitation is under researched. We sought ICU multidisciplinary opinion to primarily assess the relevance of taste deprivation on patient care and recovery, and to identify future opportunities for innovation and research.

Background: During the COVID-19 pandemic, intensive care units (ICUs) experienced a surge in patients with viral pneumonia, often leading to acute respiratory failure. A global rise in ICU superinfections was observed; however, it remains unclear whether the extensive use of broad-spectrum antibiotics, corticosteroids, and immunosuppressants contributed to this rise.
Objectives: We aim to identify clinical factors associated with these superinfections while analyzing epidemiologic patterns of superinfections in two different periods.
