Filter by:The weaning failure is a paramount challenge when aggressive discontinuation of respiratory support in ARDS. The aim of the study is to improve weaning safety and efficacy by a transient postextubation non-invasive respiratory support.
Data comparing respiratory drive and effort in critically ill patients with acute respiratory distress syndrome associated to different severity of COVID-19 penumonia (CARDS) and to other risk factors are lacking. Objectives: To assess respiratory drive and effort of CARDS patients at the first transition from controlled to assisted spontaneous breathing. The second aim was the rate of a composite outcome including the need of higher level of sedation
Weaning patients from the ventilator in the intensive care unit is sometimes difficult because of three main interrelated etiologies: impaired lung, heart or diaphragm function. In this context, ultrasonography performed during tests for extubation of patients may enable the diagnosis of cardiac dysfunction, loss of pulmonary aeration, diaphragm dysfunction, and venous congestion, thereby reducing the number of failures in extubation. The combination of TTE (Trans Thoracic Echocardiography), LUS (Lung Ultrasound), DUS (Diaphragmatic ultrasound) and VEXUS (Venous excess Ultrasound) may enable the identification of the etiology of weaning failure and reduce the number of extubation failures by enabling the development of an appropriate treatment strategy. With this study, it is aimed to contribute to the literature in this sense.
patients who succeeded in SBT with high lung scores by ultrasound, non-invasive ventilation, and diuretic may have a role.
We hypothesized that the accuracy of the modified cuff leak test in predicting re-intubation in tracheal intubated patients is better than that of the conventional balloon leak test, thereby further reducing the re-intubation rate.
Several studies investigated the role of specific clinical predictors of weaning success, but it is determined by a combination of different aspects that can result in success or failure. Indeed, unresolved lung disease, cardiac dysfunction, loss of respiratory and core muscle strength can play a role in a failure weaning to mechanical ventilation (MV). The investigators hypothesized that a combined score that include heart, lung, and respiratory muscle ultrasound (US) evaluation could be able to predict the ability of weaning success. Furthermore, it will be described weather the days of MV before weaning trial may affect the relevance of each clinical variable evaluated.
During weaning from mechanical ventilation, the shift from positive to negative pressure ventilation may be responsible for a cardiac dysfunction that can lead to the development of pulmonary oedema (weaning-induced pulmonary oedema, WIPO) and to the failure of spontaneous breathing trials. However, the incidence and risk factors for WIPO development are not well defined and have been investigated only by a few studies.
Nasal high flow is widely used in critically ill patients admitted to the intensive care unit (ICU) for acute hypoxemic respiratory failure. It has been shown to improve patient comfort, increase oxygenation and reduce need for intubation in some patients. The Respiratory Oxygenation (ROX) index has been established as a simple tool to help clinicians identify those patients who will succeed and those who will fail under nasal high flow and therefore predict the need for intubation. However, when nasal high flow therapy is successful, little is known as to how and when weaning of this device should be performed and what are the predictors of a safe withdrawal of the device. The objectives of this retrospective exploratory study are to identify a cut-off value of the ROX index predictive of success of the withdrawal trial, to describe a one-year use of the withdrawal trial; to describe the ROX value closest to weaning from nasal high flow, and to identify factors associated with success or failure of the withdrawal trial from nasal high flow therapy in patients receiving nasal high flow therapy.
Recently, intensive care unit acquired weakness (ICUAW) has become a hotspot issue in the patients with critical illness. The symptoms of ICUAW, including sensory impairment and muscle atrophy, may lead to poor quality of life even though the patients discharged from the ICU for a long time. Therefore, an ounce of prevention is worth a pound of cure. At the same time, early evaluation is necessary to keep critically ill patients away from ICUAW. Medical Research Council (MRC) scale is the most common approach for diagnosis clinically. Regarding the interrater variation of MRC, handgrip strength (HGS) has been thought to be a simple and accurate alternative. However, HGS does not belong to antigravity or respiratory muscle which are the first to be affected by immobilization. It is still unknown whether HGS can represent the general muscle condition in ICU or not. Additionally, previous studies have proved that patients with critical illness in the ICU would have better prognosis and less complications, if they undergo physical therapy as soon as possible. In addition to early ventilator weaning and reduced mortality rate, physical therapy could enhance quality of life (QoL) after patient discharges from hospital. However, early mobility in the ICU mainly emphasizes cardiopulmonary patients due to the traditional concept in Taiwan. Hence, the duration of mechanical ventilation in the critical patients will affect the timing to receive physical therapy, even impact the improvement of QoL. Because of these reasons, this study will investigate the relationship between HGS and muscle mass among patients with critical illness and find the predictors of the short-term and long-term goals in the ICU, including ventilator weaning and QoL after hospital discharge.
The factors of success of decannulation are not well known in the literature and the decision to decannulate is mainly based on clinical judgment. The failure rate of decannulation is between 2 and 25% with a poor prognosis in case of failure. The objective of this study is to determine the factors associated with successful tracheostomy removal in patients hospitalized in a respiratory weaning unit. The secondary objectives are to evaluate in tracheostomized and hospitalized patients in weaning unit: - The prevalence of successful tracheostomy removal; - The prevalence of successful weaning from mechanical ventilation; - Factors associated with successful weaning from mechanical ventilation; - Demographic characteristics of these patients at admission; - Ventilatory characteristics of these patients at admission; - Biological characteristics of these patients at admission; This is a prospective, single-centre, interventional cohort study with an expected duration of 2 years. All patients admitted to the respiratory weaning unit in the Forcilles' hospital, with a tracheostomy and an expected duration of mechanical ventilation > 48 hours will be consecutively included. All factors potentially associated with successful tracheostomy removal will be prospectively collected: severity factors related to the ICU stay, ventilatory factors, respiratory and extra-respiratory factors.
