Filter by:The purpose of this international, multicenter service review is to describe and compare ventilation management in patients at risk of acute respiratory distress syndrome (ARDS) versus patients not at risk and patients with established ARDS, and to ascertain whether certain ventilator settings and ventilation parameters are associated with pulmonary complications or development of ARDS after start of ventilation in patients in intensive care units (ICUs) in Asian countries. Participating centers will include adult patients undergoing mechanical ventilation in the ICU during a 28-day period. Patients' data will be collected during the first 7 days in the ICU, or until ICU discharge. Follow up is until ICU discharge. The primary outcome includes two main ventilator settings, i.e., tidal volume and the level of positive end-expiratory pressure. Secondary endpoints are development of ARDS in patients without ARDS at the onset of mechanical ventilation, worsening of ARDS in patients with ARDS at the onset of mechanical ventilation, pulmonary infection, other pulmonary complications, need for tracheostomy, duration of ventilation, length of ICU stay and ICU mortality.
The m-CCRP randomized controlled trial will evaluate the efficacy of a collaborative critical care recovery program from acute respiratory failure (ARF) survivors in accomplishing the Institute of Healthcare Improvement's triple aims of better health, better care, at lower cost. Primary Aim: To assess the efficacy of m-CCRP in improving the QOL of ARF survivors compared to attention control at twelve months post hospital discharge. Secondary Aims: 1. To evaluate the efficacy of m-CCRP in improving cognitive, physical, and psychological function of ARF survivors at twelve months post hospital discharge when compared to attention control. 2. To evaluate the efficacy of m-CCRP in reducing health-care utilization, defined as time from enrollment to emergency department visits and/or hospital re-admission, by ARF survivors as compared to attention control at twelve months post hospital discharge.
Non invasive ventilation (NIV) is generally delivered by pneumatically triggered and cycled-off Pressure Support (PSP) through a facial mask. Compared to PSP, Neurally Adjusted Ventilatory Assist (NAVA), which is the only ventilatory mode using a non-pneumatic signal, i.e., diaphragm electrical activity (EAdi), to trigger and drive ventilator assistance, improves patient-ventilator interaction. A specific setting to generate neurally controlled Pressure Support (PSN) was recently proposed for delivering NIV by helmet. The investigators here compare PSN with PSP and NAVA during NIV by facial mask, with respect to arterial blood gases (ABGs), patient comfort, and patient-ventilator interaction and synchrony. Three 30-minute trials of NIV were randomly delivered to 14 patients immediately after extubation to prevent post-extubation respiratory failure: 1) PSP, with an inspiratory support ≥8 cmH2O; 2) NAVA, adjusting the NAVA level to achieve a comparable peak EAdi (EAdipeak) as during PSP; 3) PSN, setting the NAVA level at 15 cmH2O/mcV with an upper airway pressure (Paw) limit such to obtain the same overall Paw applied during PSP. We assessed EAdipeak, ABGs, peak inspiratory flow (PIF), time to reach PIF (PIFtime), pressure-time product of the first 300 (PTP300-index) and 500 (PTP500-index) milliseconds after initiation of patient effort, patient comfort, inspiratory trigger delay (DelayTR-insp), and the rate of asynchrony, as assessed by the Asynchrony Index (AI%).
Endotracheal intubation is common in the care of critically ill patients. Complications of airway management in this setting are frequently encountered and may be associated with an increased risk of death. The prevention of complications during urgent and emergent endotracheal intubation is a key focus for airway management research. Post-intubation hypotension (PIH), a common complication of endotracheal intubation in the critically ill, may be prevented by a bolus of intravenous fluid prior to the start of the procedure, but this approach has not been examined in a prospective trial. There are no randomized trials of intravenous fluid administration to prevent PIH in critically ill adults. The investigators propose a randomized trial of fluid loading to prevent PIH in critically ill adults.
This study proposes a novel early intervention combining Intravenous (IV) amino acids plus in-bed cycle ergometry exercise to improve physical outcomes in critically ill patients. The investigators hypothesize that this innovative approach will improve short-term physical functioning outcomes (primary outcome), as well as amino acid metabolism, body composition, and patient-reported outcomes at 6-month follow-up.

VENIM is a multicenter, open-label, parallel-group randomized controlled trial of studying the initial ventilation strategy for adult immunocompromised patients with acute respiratory failure.
Acute respiratory failure is the leading cause of ICU admission of immunocompromized patients. In this subgroup of patients, the need for intubation and invasive mechanical ventilation occurs in about 50% of cases and is associated with very a high mortality rate, reaching 70% of cases. Therefore, noninvasive oxygenation strategies have been developed to avoid intubation. More than 15 years ago, 2 trials have suggested that NIV could decrease intubation and mortality rates of immunocompromized patients as compared to standard oxygen through a mask. However these results have not been confirmed in a recent large trial. HFNC is a recent and well-tolerated oxygenation technique. In a recent trial, HFNC alone could decrease mortality and intubation rates in patients with ARF as compared to NIV. Similar findings have been reported in a post-hoc analysis on immunocompromized patients excluding those with profound neutropenia. Likewise in a retrospective monocentric cohort of immunocompromized patients, we reported better outcomes with HFNC than with NIV.
Over the last two decades, non-invasive ventilation (NIV) has been widely reported as an effective method to avoid the need of endotracheal intubation (ETI) and improve survival in the acute care setting. Given the risks associated with either premature NIV discontinuation or delays in NIV interruption, evaluating readiness to weaning from NIV is a critical challenge in patients with Acute Respiratory Failure (ARF). Up to date, bedside measurements used to predict NIV outcomes are extremely limited. NIV weaning as well as decision of ETI are mainly supported by clinical and physiologic parameters. More sophisticated techniques used to predict weaning outcome during spontaneous breathing trials have never achieved a bedside broad-spectrum use due to their invasiveness, the inconsistent results in demonstrating reproducible outcomes, the requirements of additional trainee personnel and complicated equipment, and the difficult application in awake and non-intubated patients. Recently, ultrasound has been used for the rapid assessment of diaphragm function in acutely ill patients. The advantages of the ultrasound in detecting diaphragm dysfunction as compared with other techniques are the less invasiveness, the avoidance of radiation hazards and the bedside feasibility. Direct imaging of changes in diaphragm thickening (DT) during spontaneous breathing may provide the assessment of both the muscle and the respiratory pump functioning. Indeed, DT has been correlated with the diaphragm strength and the muscle shortening. The volume of diaphragm muscle mass remains constant while it contracts. Consequently, as the muscle shortens it thickens itself and measurements of changes in such a thickening (DT) are inversely related to changes in diaphragm length. Studies in patients with diaphragm paralysis have confirmed the absence of DT. Moreover, since the diaphragm is the major muscle of inspiration, the presence of diaphragm shortening and contraction may predict successful extubation in patients who are invasively ventilated. The aim of the present study is to assess whether DT as measured by ultrasound may predict NIV outcome in patients with de-novo ARF admitted to the Emergency Department (ED).
Heparin is a blood thinner used to prevent blood clots in patients on a form of life-support called ECMO. Heparin can cause bleeding - the most common complication of ECMO. New materials used in ECMO machines may help prevent clots - this could allow the use of lower doses of heparin which might reduce the risk of bleeding. Our study will compare low dose to high dose heparin in patients on ECMO. We think low dose heparin may be adequate to prevent clotting, but may cause less bleeding and be safer for patients.
