Filter by:This is a double-blind, randomized, placebo-controlled, Phase 2b/3 two-part adaptive clinical trial. The trial is designed to investigate the pharmacokinetics and the efficacy of multiple dosing regimens of melatonin and to confirm the efficacy and safety of one dosing regimen in prevention for delirium.
This randomised study was designed to assess the efficacy of nebulised heparin and salbutamol in improving lung function in mechanically ventilated patients with AECOPD.
Maintaining mechanically-ventilated patients in semi-recumbent position (defined by a head of bed inclination between 30° and 45°) would decrease the risk of pneumopathy occurrence in those patients. However, such a bed inclination frame is still difficult to maintain in day-to-day care. The aim of the study is to evaluate the impact of an electronic monitoring device on the proportion of time spent per day in semi-recumbent position, as defined by a head of bed inclination between 40° and 50°, in mechanically-ventilated patients.
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.
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)
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.
The study compares automated settings (Intellivent) with protocolized settings of the ventilator after cardiac surgery. The settings concern the respiratory rate, the inspiratory and expiratory pressure and FiO2. The aim of the study is to demonstrate that automated settings are feasible and safe. The study design is a randomized controled study. 30 patients will be ventilated with automated mode and 30 patients with protocolized settings after cardiac surgery. The hypothesis is that the automated mode allows a safer ventilation with better maintain of the patient in predefined optimal zone of ventilation.
Objective: To compare the effects of a protective versus a conventional ventilatory strategy, on systemic and in lung production of tumor necrosis factor-alpha (TNF-alpha) and interleukin-8 (IL-8) in patients without lung disease. Hypothesis: High tidal volumes induce inflammation in patients without lung disease Design: Prospective control-randomized study. Patients and Setting: Twenty patients without lung disease and submitted to mechanical ventilation admitted to one trauma and one general adult intensive care unit of two different university hospitals. Interventions: Patients were randomized to receive mechanical ventilation either with tidal volume (VT) of 10-12 ml/kg predicted body weight (high VT group) or with VT of 5-7 ml/kg predicted body weight (low VT group) with an O2 inspiratory fraction (FIO2) enough to keep arterial oxygen saturation > 90% with positive end-expiratory pressure (PEEP) of 5 cmH2O during 12 hours after admission to the study.
Sleep disruptions are extremely common in high-risk critically ill patients. The investigators want to analyse oral melatonin potentialities as a sedative and a free-radicals scavenger for critically ill patients, and secondarily for preventing Delirium during their ICU stay and post-traumatic stress disorders after ICU discharge.
To study all ICU patients with an independent baseline functional status, who experience a critical illness requiring intubation and mechanical ventilation, evaluating the role of protocol-directed, early physical and occupational therapy on the incidence of critical illness associated functional debilitation. Our goal is to hasten the recovery of independent physical functioning as well as to reduce ICU delirium in the group of patients who begin this intervention from the earliest hours of ventilator dependence.
