Filter by:A majority (65-85%) of critically ill patients admitted in intensive care units with a confirmed diagnostic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) developed an acute respiratory distress syndrome (ARDS) according to BERLIN criteria. Gattinoni et al. recently described that the ARDS related to SARS-CoV-2 was not a "Typical" ARDS. Patients affected by this infection present indeed a major hypoxemia, which was surprisingly associated in early phase with a high compliance of respiratory system, more than 50 ml/cm H2O in most cases. The cornerstone of current treatment in case of ARDS is the use of "lung protective" ventilation, including limited tidal volumes (VT), low end-inspiratory plateau pressures while maintaining sufficiently-high positive end-expiratory pressures (PEEP). However, high levels of PEEP in patients may have detrimental effects on hemodynamic status and fluid retention, particularly when the respiratory system compliance is normal. High PEEP may also lead to overdistension and an increase of alveolar dead space. The airway pressures commonly monitored does not reliably reflect the impact of pressures on the lung parenchyma. Elastance of chest wall may indeed largely influence values of airways pressions. In contrast, transpulmonary pressure obtained using esophageal pressure (Pes) directly reflect lung overdistension risk and lung properties. In order to better understand this new kind of ARDS characterized by modest recruitable profile and to better personalize mechanical ventilation setting and therapy it is obvious to precise transpulmonary pressure.
The most feared complication of COVID-19 infection is the occurrence of an acute respiratory distress syndrome (ARDS) that requires ICU admission and prolonged mechanical ventilation in more than 2% of the affected patients. Establishing the correct time to extubate mechanically ventilated patients is a crucial issue in the critical care practice. Delayed extubation has several consequences such as patient's mortality, health-care-related complications, neuropsychological adverse events. The aim of the INVICTUS study is to evaluate whether a CTUS-based MV weaning strategy could reduce the duration of mechanical ventilation of ARDS COVID-19 ICU patients by 72 hours, compared with usual medical care.
The objective of this study is to develop and evaluate an algorithm which accurately predicts mortality in COVID-19, pneumonia and mechanically ventilated ICU patients.
The objective of the study is to evaluate the efficacy of helmet NIV in reducing the duration of invasive mechanical ventilation in order to minimize ventilator needs during the COVID-19 pandemic.
The purpose of this national, multicenter service review is to determine and compare ventilation management in COVID-19 patients in the Netherlands, and to determine whether certain ventilation settings have an independent association with duration of ventilation. In every adult invasively ventilated COVID-19 patient from a participating ICU, granular ventilator settings and parameters will be collected from start of invasive ventilation for up to 72 hours. Follow up is until ICU and hospital discharge, and until day 90. The primary outcome includes main ventilator settings (including tidal volume, airway pressures, oxygen fraction and respiratory rate). Secondary endpoints are ventilator-free days and alive at day 28 (VFD-28); duration of mechanical ventilation; use of prone positioning and recruitment maneuvers; duration of ICU and hospital stay; incidence of kidney injury; and ICU, hospital, 28-day and 90-day mortality.
Inspiratory muscle weakness develops rapidly in ventilated critically ill patients and is associated with adverse outcome, including prolonged duration of mechanical ventilation and mortality. Surprisingly, the effects of critical illness on expiratory muscle function have not been studied. The main expiratory muscles are the abdominal wall muscles, including the external oblique (EO), internal oblique (IO) and transversus abdominis muscles (TRA). These muscles are activated when respiratory drive or load increases, which can be during e.g. exercise, diaphragm fatigue, increased airway resistance, or positive airway pressure ventilation. The abdominal wall muscles are also critical for protective reflexes, such as coughing. Reduced abdominal muscles strength may lead to decreased cough function and thus inadequate airway clearance. This will lead to secretion pooling in the lower airways, atelectasis, and ventilator associated pneumonia (VAP). Studies have shown that decreased cough function is a risk for weaning failure and (re)hospitalization for respiratory complications. Further, high mortality was found in patients with low peak expiratory flow. Considering the importance of a proper expiratory muscle function in critically ill patients, it is surprising that the prevalence, causes, and functional impact of changes in expiratory abdominal muscles thickness during mechanical ventilation (MV) for critically ill patients are still unknown. Ultrasound is increasingly used in the ICU for the visualization of respiratory muscles. In a recent pilot study the investigators confirmed the feasibility and reliability of using of ultrasound to evaluate both diaphragm and expiratory abdominal muscle thickness in ventilated critically ill patients (manuscript in preparation). Accordingly, the primary aim of the present study is to evaluate the evolution of abdominal expiratory muscle thickness during MV in adult critically ill patients, using ultrasound data.
The overall objective of the study is to conduct an observational study involving intensive care unit patients receiving mechanical ventilation and determine if there are differences in diaphragm thickness ultrasound measurements during expiratory and inspiratory phases in a controlled and spontaneous mode. For patients receiving sedatives, an additional set of measurements will be taken during a standard of care interruption of sedatives
Hemodynamic and fluid optimization during perioperative period can reduce postoperative morbidity. The assessment of preload and determination of whether the patient is fluid responsive is still challenging. Static preload indices such as central venous pressure are not accurate to assess fluid responsiveness contrary to dynamic preload indices such as pulse pressure variation (PPV) and stroke volume (SV) variation. However, such indices suffer from several limitations and should be used under strict conditions. Alternative dynamic methods such as lung recruitment maneuvers (LRM) have been developed LRM can be used to reopen or prevent collapsed lung under mechanical ventilation so as to decrease respiratory complications. LRM induces a transient increase in intra-thoracic pressure and decreases in venous return, leading to a decrease in left ventricular end-diastolic area and stroke volume. Several studies have shown that the PEEP-induced decrease in stroke volume is related to pre-existing preload responsiveness. Few studies have also shown that LRM can represent a functional test to predict fluid responsiveness. However, monitoring stroke volume during LRM to assess fluid responsiveness is costly, and cardiac output devices may not be reliable. In this context, central venous pressure (CVP) or systemic arterial parameters monitoring are easily accessible and inexpensive during major surgery.
Patients admitted to the Intensive Care Units (ICU) that receive mechanical ventilation need high dose sedative and analgesic medication that may have side effects. Despite this, many of them also experience anxiety and added stress. Musical intervention is a useful non-pharmacological tool without adverse effects safe and easy to provide for patients with mechanical ventilation admitted to the Intensive Care Units. Its use reduces the use and dose of sedatives, reduces stress and environmental noise. It should be considered in the measures of control of anxiety and noise in the ICU. The objective of the study is to analyze whether the implementation of a musical intervention can be an effective non-pharmacological intervention in the therapy of patients undergoing mechanical ventilation admitted to an Intensive Care Unit of a High Complexity Hospital.
The purpose of this study is to understand the relationship between intracranial pressure and airway pressures during mechanical ventilation. This study is a single-center, prospective cohort study to be conducted at Beth Israel Deaconess Medical Center. The investigators will recruit patients with severe brain injury (GCS 8 or less) who receive intracranial pressure monitoring and mechanical ventilation as part of their routine medical care. The primary endpoint is the change in intracranial pressure as a function of positive end-expiratory pressure. There is only one study encounter with safety monitoring for up to 24 hours after. No additional follow up is required.
