NCT ID: NCT05944588 Recruiting - Ultrasound Clinical Trials

Predictive Value of Chest Ultrasound Observation on Extubation Failure

ECHOEXTUB
Start date: May 24, 2023
Phase:
Study type: Observational [Patient Registry]

The use of mechanical ventilation in intensive care concerns the majority of patients, most often to compensate for respiratory failure, but for other organic failures requiring therapeutic artificial coma. During the sedation phase, many elements of management can modify the patient's clinical parameters. Indeed, mechanical ventilation with a positive expiratory pressure mainly modifies the venous return by decreasing it, and therefore many modifications of the hemodynamic parameters result from it. In addition, other elements of management, such as iterative fillings, vasopressor and inotropic amines, as well as sedative drugs not only modify the hemodynamics, but also the ventilatory mechanics. Extubate a patient in intensive care is always complex, because the assessment must be multifactorial and this is not without risk for the patient. Many complications can arise if it ends in failure. They can be linked to mechanical causes (laryngeal oedema, tracheal stenosis, pneumothorax...) but also to non-mechanical causes, such as inappropriate sedation, overload, neuromuscular deficit. Extubation is primarily based on the patient's level of consciousness, as well as the successful progress of the patient during a ventilatory weaning trial, carried out after a return to spontaneous ventilation with inspiratory support. This ventilatory weaning test precedes extubation and is performed for any patient intubated for more than 48 hours. Since the 1950s, ultrasounds have become more and more important in the field of medical diagnosis and therapeutic decision support, even more recently in the world of intensive care. The contribution of echocardiography in a patient in the process of extubation has already been evaluated and has proven to be a valuable aid. For nearly 20 years, the use of pulmonary ultrasound has emerged and allows rapid diagnosis at the patient's bedside of mechanical anomalies such as gaseous or liquid effusion, an anomaly in the compliance of the pulmonary parenchyma, possibly in link with diaphragmatic dysfunction or even signs in favor of a picture of pulmonary overload, thanks to ultrasound artefacts such as B lines or even alveolar derecruitment by atelectasis. The role of pulmonary ultrasound in helping to decide on extubation remains poorly established, we propose an observational study evaluating the predictive value of chest ultrasound in pre-extubation with the aim of determining if ultrasound signs are able to predict a potential failure of this extubation. Indeed, the risks of extubation failure being much higher than those of ventilatory weaning failure, it seems necessary to focus our research on this component. This study must include patients in spontaneous mechanical invasive ventilation with pressure support, presenting the criteria for a ventilatory weaning test in view of a potential extubation.

NCT ID: NCT05918575 Recruiting - Obesity, Morbid Clinical Trials

Postextubation Use of Noninvasive Respiratory Support in Severely Obese Patients

Start date: July 10, 2023
Phase: N/A
Study type: Interventional

Around 20% of the obese patients with higher body mass index (BMI) who are taken off the breathing tube and breathing machine (ventilator) end up needing it back to support breathing. The re-application of breathing tube is associated with poor outcomes, including high risk of pneumonia, longer hospital stays, and death. The purpose of this study is to assess if prophylactic use of noninvasive breathing support after removing the breathing tube lowers the chance of needing the breathing tube again.

NCT ID: NCT05637099 Recruiting - Clinical trials for Mechanical Ventilation

The Value of Repeated BIOMarker Measurements During an SBT to Predict EXtubation Failure in ICU Patients

BIOMEXIC
Start date: August 1, 2022
Phase:
Study type: Observational

The Value of Repeated BIOMarker Measurements During an SBT to Predict EXtubation Failure in Mechanically Ventilated ICU Patients

NCT ID: NCT05550259 Not yet recruiting - Extubation Failure Clinical Trials

Ventilation Support for the PREvenTion of EXTubation Failure

PRETEEXT
Start date: October 2022
Phase: N/A
Study type: Interventional

Reintubation after failed extubation would be associated with increased mortality. Therefore, extubation failure remains a major concern in ICU. Few randomized controlled studies have assessed the benefit for a systematic respiratory support (noninvasive ventilation or high flow nasal cannula) applied at the time of extubation to reduce reintubation rates in patients at high and low risk for reintubation. In addition, these studies reported discordant results. Therefore, there are some concerns regarding effectiveness and systematic uptake of a respiratory support after extubation into usual practice.

NCT ID: NCT05487573 Not yet recruiting - Extubation Failure Clinical Trials

Performance of the Variation in Arterial Lactatemia During a Spontaneous Breathing Trial (SBT) in the Prediction of Extubation Failure

PREDILACT
Start date: September 15, 2022
Phase:
Study type: Observational

Extubation failure (EF) is independently associated with excess mortality of critically ill patients. To avoid EF, critically ill patients being weaned from invasive mechanical ventilation (IMV) perform spontaneous breathing trial (SBT), which is the litmus test for determining the ability to breathe without a ventilator. Thus, the performance of the SBT during weaning from IMV to predict successful extubation is crucial. The investigators hypothesize that patients with EF increase arterial lactate concentration during SBT due to increased work of breathing and hypoxia. The aim of this study is to evaluate the performance of variation in arterial lactate concentration before and after SBT in predicting successful extubation in critically ill patients.

NCT ID: NCT05446272 Recruiting - Clinical trials for Bronchopulmonary Dysplasia

The Diaphragmatic Initiated Ventilatory Assist (DIVA) Trial

DIVA
Start date: August 3, 2022
Phase: N/A
Study type: Interventional

DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 24-27 6/7 weeks gestation undergoing extubation from mechanical ventilation, whether (I) Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) (C) compared with Non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), will reduce the incidence of (O) extubation failure within (T) 5 days (120 hours) of extubation.

NCT ID: NCT05081973 Recruiting - Clinical trials for Invasive Mechanical Ventilation

A Model for Predicting Extubation Success in Premature Babies

Start date: April 20, 2021
Phase:
Study type: Observational

Invasive mechanical ventilation is a life-saving treatment in critically ill newborns with respiratory failure. However, continuing this treatment for a long time may have negative consequences, especially bronchopulmonary dysplasia (BPD) secondary to mechanotrauma. For this reason, it is essential to terminate the mechanical ventilation treatment at the most appropriate time. About half of the extremely preterm babies may fail extubation even if the clinical criteria traditionally used for extubation are met. Unsuccessful extubation is associated with increased intraventricular bleeding, death, BPD, death or BPD, longer duration of ventilator support. When respiratory failure and lung pathologies of extremely preterm babies begin to improve, the target for mechanical ventilation should be early and successful extubation. Currently, the decision to extubate a preterm baby is primarily based on clinical judgment. Only a few studies that showed the low predictive value and limited utility using different measures have evaluated readiness for extubation. Lung ultrasonography (USG) is a noninvasive bedside technique that has been found useful for predicting the success of weaning from the ventilator in adults; however, very little data are available in neonates. In a recently published study, it was proposed an extubation readiness estimation tool based on clinical and demographic data of preterm babies who were attempted elective extubation. The researchers' hypothesis is that the use of a model based on extubation success scoring and lung USG scoring before extubation reduces the failure of the first extubation attempt in very low birth weight infants. The aim of the study is to evaluate the value of using an integrated model based on pre-extubation "extubation readiness predictor" and lung USG scoring to predict extubation success in preterm babies undergoing invasive mechanical ventilation.

NCT ID: NCT04125342 Completed - Extubation Failure Clinical Trials

Postextubation High-flow Therapy vs Noninvasive Ventilation in Obese or at High-risk Patients

HINFOR
Start date: June 1, 2020
Phase: N/A
Study type: Interventional

The main aim is to demonstrate whether reintubation rate is lower with preventive conditioned noninvasive ventilation (NIV) rather than with High-flow oxygen therapy (HFOT) in obese intermediate-risk patients and in high-risk patients.

NCT ID: NCT04010617 Recruiting - Stroke Clinical Trials

PES to Avoid Extubation Failure in Intubated Stroke Patients at High Risk of Severe Dysphagia

Start date: July 1, 2018
Phase: N/A
Study type: Interventional

Post-extubation dysphagia (PED) recently became a growing concern as a major risk factor for extubation failure and significant contributor to poor patient outcomes with prevalence rates ranging from 12% to 69%, being highest in neurological patients (93%). Pharyngeal electrical stimulation (PES) has been shown to improve airway safety and swallowing function tracheostomized stroke patients, thereby enhancing decannulation in this patient cohort. In the present study the investigators evaluate whether PES is safe, feasible and effective in orotracheal intubated stroke patients at high risk of extubation failure.

NCT ID: NCT03361683 Completed - Extubation Failure Clinical Trials

Post-extubation High-flow Nasal Oxygen for Preventing Extubation Failure

Start date: October 1, 2017
Phase: N/A
Study type: Interventional

Patients intubated due to acute respiratory failure have a high risk of infectious complications, airway injuries and multiple organic failure, so performing a successful extubation from mechanical ventilation is key. Between 10 and 20% of patients develop extubation failure, which is related to an increased in-hospital death rate, infections, higher costs and longer hospital stays. High-flow nasal oxygen therapy delivers heated, humidified air at flows up to 60L/min, and an oxygen concentration close to 100%, providing a fresh air reservoir at the naseo-pharyngeal level, evening out the peak inspiratory flow rate of the patient, improving air conductance, promoting secretion management, increasing end-expiratory lung volume, and applying a positive end-expiratory pressure. Such effects result in decreased breathing work, dyspnea relief, improved use tolerance, increased oxygenation, and lower fraction of inspired oxygen in patients with hypoxemic respiratory failure. High-flow oxygen therapy has recently been described to decrease extubation failure in a group of patients classified with low failure risk, in comparison to Venturi mask, and it was not inferior to non-invasive mechanical ventilation in high risk patients. However, it is worth pointing out that a large percentage of the patients included in such studies did not develop acute respiratory failure primarily. Given the beneficial effects described above, the investigators hypothesize that high-flow nasal oxygen therapy decreases the risk of extubation failure in a group of patients that required invasive mechanical ventilation due to primary acute hypoxemic respiratory failure.
