Prospective Multicentre Mixed Methods Study to Explore Extubation Practices and Respiratory Outcomes in Extremely Preterm Neonates.

The purpose of this observational study is to learn about neonatologists' perceptions of extubation readiness and extubation and reintubation practices in extremely preterm infants in the first 2 weeks of life using prospective qualitative and quantitative data. Actual extubation readiness is defined as successful extubation, defined as no reintubation in the 7 days following extubation. Key research questions are: How do clinicians assess extubation readiness in this population? Does this assessment correlate with actual extubation success? What factors (reasons, clinical status, ventilatory parameters) are associated with extubation readiness? Patients born before 28 weeks gestational age and admitted to the neonatal intensive care unit (NICU) within the first 24 hours are be included. The attending physician will complete a prospectively administered questionnaire with open-ended and multiple-choice questions to daily assess the decision and rationale for extubation or non-extubation of patients mechanically ventilated during the first 15 days of life. Patient characteristics, respiratory outcomes, and mortality will be recorded until the end of hospitalisation and/or definitive weaning from any ventilatory support or supplemental oxygen.

Impact of Biphasic Cuirass Ventilation Compared to Non Invasive Ventilation in High Risk Extubations

subjects on mechanical ventilator who are about to be extubated to Non invasive ventilation because the physician thinks they are high risk for failure will be approached and consented for our study. Once randomized they will either be on the standard of care Non invasive arm or the intervention arm which would mean they are placed on the Biphasic cuirass ventilation.

One-Hour Positive Pressure Ventilation After a T-Piece Spontaneous Breathing Trial

This is a randomized, open, multicenter, pragmatic, adaptive clinical trial with intention-to-treat analysis. The study will compare two weaning strategies from mechanical ventilation in critically ill patients admitted to intensive care units, with more than 72 hours of mechanical ventilation and with a successful spontaneous breathing trial on T-piece. Immediately after a successful spontaneous breathing trial, eligible patients will be randomized into 2 groups that will be treated according to one of the following interventions: 1. One-hour positive pressure ventilation: as soon as the success of the spontaneous breathing trial is confirmed, the patient is submitted to mechanical ventilation for 1 hour using the previous ventilatory parameters and, afterwards, extubated. 2. Immediate extubation: the patient is extubated immediately after the success of the spontaneous breathing trial.

One-Hour Positive Pressure Ventilation After a Pressure Support Spontaneous Breathing Trial

This is a randomized, open, multicenter, pragmatic, adaptive clinical trial with intention-to-treat analysis. The study will compare two weaning strategies from mechanical ventilation in critically ill patients admitted to intensive care units, with more than 72 hours of mechanical ventilation and with a successful spontaneous breathing trial on pressure support. Immediately after a successful spontaneous breathing trial, eligible patients will be randomized into 2 groups that will be treated according to one of the following interventions:1) One-hour positive pressure ventilation: as soon as the success of the spontaneous breathing trial is confirmed, the patient is submitted to mechanical ventilation for 1 hour using the previous ventilatory parameters and, afterwards, extubated.2) Immediate extubation: the patient is extubated immediately after the success of the spontaneous breathing trial.

A New Tool for Extubation Readiness in Mechanically Ventilated Patients: Readiness for EXtubation Score

Liberation from mechanical ventilation involves three steps: weaning, readiness assessment, and extubation. Readiness is determined using clinical criteria such as improvement of the underlying condition, hemodynamic stability, and adequate respiratory effort. Successful extubation is defined as not requiring invasive support within 48 hours. Due to the complexity of ICU patients, various clinical parameters and multi-component scores have been developed to predict extubation success. This study aims to develop and evaluate a multi-component score, the Readiness for EXtubation score (REXs), to predict extubation readiness in ICU patients under invasive mechanical ventilation.

Postextubation Use of Noninvasive Respiratory Support in Severely Obese Patients

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.

The Diaphragmatic Initiated Ventilatory Assist (DIVA) Trial

DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 23 0/7-28 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.

Rehabilitation Practices in Critically Ill Patients Receiving Invasive Mechanical Ventilation in the Intensive Care Unit.

This international, multicenter, observational study aims to describe rehabilitation practices in Intensive Care Units (ICUs) worldwide. The primary objective is to provide an overview of current rehabilitation strategies used in ICUs globally. Secondary objectives include assessing the relationship between rehabilitation and key ICU outcomes such as ICU and hospital mortality, length of stay, duration of invasive ventilation, extubation failures, and long-term outcomes including quality of life and functional performance 28 days post-ICU discharge. The study will also compare rehabilitation practices across different geographic and economic regions to identify potential disparities. The study is structured into three modules, with participation contingent on local resources and feasibility. The BASIC Module (mandatory for all centers) gathers fundamental data on rehabilitation practices and their association with patient outcomes. The EXTENDED Module (optional) collects more detailed information on the type, timing, duration, and safety of rehabilitation interventions, including passive exercises, active mobilization, respiratory therapies, dysphagia training, occupational therapy, and cognitive support. The EXTENDED FOLLOW-UP Module (optional) evaluates the patient's quality of life and functional recovery 28 days after ICU discharge. By examining global rehabilitation practices and their impact on patient outcomes, this study aims to improve rehabilitation strategies in ICUs, contributing to better patient care, recovery, and long-term health outcomes.

Risk Factors of Extubation Failure in PICU Patients

Up to 20% of MV patients experience EF \[10\]. EF is defined as the need to reinsert the endotracheal tube to resume MV in patients extubated for less than 48 hours. It has high rates of morbidity and mortality, prolongs the duration of MV and thus causes a longer stay in the PICU and risk of complications such as the need for tracheostomy, the incidence of pneumonia and pulmonary damage, and finally, costs increase as well and death \[10, 11\] .
