NCT06124404
This is a Phase II, dose-escalation clinical trial conducted in mechanically ventilated patients receiving sedation no longer than 24 hours. The efficacy, safety, and pharmacokinetics of remimazolam besylate were evaluated using a randomized, single-blind design.
NCT06791798
The aim of the current study is to compare the effects of ventilator hyperinflation and vibrocompression on lung compliance in mechanically ventilated patients.
NCT06675942
Although mechanical ventilation (MV) is life-saving, it is associated with several complications. The establishment of an artificial airway impairs the cough reflex and mucociliary function, leading to the accumulation of secretions in the tracheobronchial tree. This increases the risk of pneumonia and lung atelectasis. Usual care for mechanically ventilated patients includes airway suctioning via the tracheostomy tube, which clears only a limited portion of the airway and is ineffective at removing peripheral airway secretions. To address this, airway clearance guidelines recommend various airway clearance techniques (ACTs) for mechanically ventilated patients to enhance mucus removal. However, the lack of standardized, effective evaluation criteria makes selecting the optimal ACT a challenge.
NCT06182553
Mechanical ventilation (MV) is crucial in managing respiratory insufficiency. However, prolonged use can cause complications. Various strategies have been explored to optimize patient outcomes. Patients receiving IMV face multiple challenges in clearing lung secretions, such as inadequate humidification, high oxygen fractions, use of sedatives/analgesics, basal lung disease, and mechanical interference with secretion elimination near the trachea. Airway suctioning may not be sufficient in clearing the airway of mechanically ventilated patients, especially if they are paralyzed or lack a preserved cough reflex. This can lead to secretion retention, which may cause hypoxemia, atelectasis, ventilator-associated pneumonia, and delay weaning from MV. Bronchial hygiene is believed to improve respiratory system compliance by increasing Cdyn and Cst. Airway clearance techniques are commonly used in the treatment of patients with IMV to improve their pulmonary function through bronchial clearance, expansion of collapsed lung areas, and balancing of the ventilation/perfusion ratio. Physiotherapy methods including postural drainage, manual rib-cage compression (MRC), manual hyperinflation, positive end-expiratory pressure-zero end-expiratory pressure (PEEP-ZEEP) maneuver, and tracheal suctioning can alleviate atelectasis and improve bronchial hygiene. Two effective techniques for improving lung function and gas exchange are Expiratory Rib Cage Compression (ERCC) and the PEEP-ZEEP maneuver. ERCC applies external pressure during expiration, and PEEP-ZEEP temporarily reduces Positive End-Expiratory Pressure (PEEP) to 0 cmH2O, followed by a rapid return to the original PEEP level during expiration. Both techniques help to mobilize and remove airway secretions, ultimately improving lung function and gas exchange.
NCT03333395
This randomised study was designed to assess the efficacy of nebulised heparin and salbutamol in improving lung function in mechanically ventilated patients with AECOPD.
NCT03800849
A prospective cohort study carried out in four ICUs in Uganda. All patients, 18 years and above initiated on mechanical ventilation will be recruited. Patients' data will be collected from the files and charts at initiation of mechanical ventilation. Patients will then be followed up for death / discharge within 28 days in ICU.
NCT01237886
Knowing when to liberate patients from mechanical ventilation (i.e. removal of breathing or endotracheal tube or extubation) is critically important, as both prolonged ventilation and failed extubation are both associated with harm and risk of death. Our objective is to improve the safety of extubation by harnessing hidden information contained in the patterns of variation of heart and respiratory rate measured over intervals-in-time. Currently, to assess a patient's ability to be extubated, a spontaneous breathing trial (SBT) is routinely performed, where the level of ventilator support is reduced, and their response is observed in order to help predict if they will tolerate extubation (i.e. complete removal of ventilator support). Given that health is associated with a high degree of variation of physiologic parameters (e.g. heart and respiratory rate), and illness \& stress are associated with a loss of variability, the investigators aim to uncover the loss of variation as a measure of stress during SBT's. The investigators hypothesize that maintaining stable heart rate and respiratory rate variability (HRV and RRV) throughout the SBT will predict subsequent successful extubation, and conversely, a reduction in either HRV or RRV manifest during a SBT predicts extubation failure. A pilot study has demonstrated feasibility, and compelling preliminary results. A website, centralized data storage and analysis, and a trans-disciplinary team of scientists are in place to definitively test this novel technology. Determination of when to extubate critically ill patients remains a high-stakes clinical challenge; and improved prediction of extubation failure has potential to save lives and reduce costs in critically ill patients.
NCT01997931
This prospective randomised controlled trial was designed to assess the effectiveness of the Bispectral Index Sedation (BIS) monitor in supporting clinical, sedation management decisions in mechanically ventilated ICU patients. The primary hypothesis for the study is that patients with Bispectral Index Sedation (BIS) monitoring will receive less sedation then those receiving standard sedation management. The secondary hypotheses are: 1. Patients with BIS have fewer ventilation days than those receiving standard sedation management. 2. Level of sedation administered will differ according to the critical care experience and qualification of the nurse.
NCT01256866
The aim of this prospective randomized study is to compare the safety and efficacy of two strategies for sedation of critically ill patients submitted to mechanical ventilation: continuous intravenous infusion of dexmedetomidine versus intravenous bolus of midazolam. The two groups will be compared as to the incidence of of delirium, evaluated with the Confusion Assessment Method for ICU (CAM-ICU) and the percentage of time within the target sedation using the Richmond Agitation-Sedation Scale (RAAS).Eligible patients will be 18 years or older intubated and mechanically ventilated for less than 48 hours prior to start of study drug and anticipated ventilation duration of at least 48 hours. Calculated sample size is 146 patients (73 patients in each group)
NCT00199641
The aim of this study is to compare two strategies of early enteral nutrition in terms of efficacy and complications in mechanically ventilated patients.
