Filter by:This study compares the short-term effects of a new humidification system (Hygrovent Gold) and two other humidification devices (heated and moisture exchanger and heated humidifier) on respiratory pattern and work of breathing, during invasive ventilation.
Experimental animal data suggest that increasing breathing pattern variability in mechanical ventilation could be beneficial. Variable ventilation can be induced through the following modes: Neurally Adjust Ventilatory Assist (NAVA), Proportional Assist Ventilation (PAV) and Variable-Pressure Support Ventilation (V-PSV). These modes have not yet been compared to each other. Pilot observations in our department suggest a feasibility in patients. The objectives of the study are to compare the impact of PSV, NAVA, PAV and V-PSV on the variability of the breathing pattern, patient-ventilator asynchrony, risk of lung overdistension, gas exchange, and repartition of ventilation.
The use of a written, pre-procedure checklist and positioning the patient with the head of the bed elevated have been proposed as interventions capable of preventing complications during non-elective intubation and are used intermittently in routine care -- however neither have been examined in a prospective trial.
Severe acute respiratory failure (ARF) requiring prolonged mechanical ventilation is the most common form of acute organ dysfunction in the hospital, and is often associated with multiple organ failure (MOF), high mortality, and functional impairment. Most studies on ARF have focused on patients in the intensive care unit (ICU) after they have been on mechanical ventilation for days and end organ damage is already established. The overall goal of this proposed project is to improve the outcomes of patients at high risk for developing severe ARF and prolonged mechanical ventilation in and outside of the ICU. The project aims to intervene early in high risk patients with an electronic medical records (EMR)-based, patient-centered checklist of common critical care practices aimed at preventing lung injury and hospital acquired adverse events that commonly lead to organ failure (Prevention of Organ Failure checklist -PROOFcheck). This application proposes a stepped-wedge, clustered randomized control trial to determine the utility of PROOFcheck to improve survival and reduce the duration of mechanical ventilation and multiple organ failure in patients identified as high risk for progressing to severe ARF and prolonged mechanical ventilation. The aims in the UH2 phase are: 1) to refine a previously validated Lung Injury Prediction Score into a pragmatic, EMR-based early prediction model to Accurately Predict Prolonged Ventilation (APPROVE), which will automatically identify patients anywhere in the hospital who are at high risk for developing severe ARF requiring mechanical ventilation >48 hours; 2) to incorporate PROOFcheck into the EMR to prompt clinicians on care practices to limit lung injury, prevent adverse events, and avoid additional organ failure; and 3) to establish the infrastructure for the proposed trial. The proposed pragmatic trial will harness the hospital-wide EMR to identify patients at high risk for prolonged mechanical ventilation with APPROVE for intervention with PROOFcheck. As such, the proposed trial aims to break out of the clinical silos by which care is currently organized in the hospital and bring patient-centered, context appropriate care to the acutely ill patient wherever and whenever the patient's condition requires it.
The investigators studied the efficiency of Macintosh laryngoscope and the King Vision video laryngoscope in adult patients scheduled for general anesthesia. Best Cormack-Lehane score obtained, glottic view time, intubation time, time to ventilation, correlation between the Mallampati classification and the Cormack-Lehane grades, and complications related to laryngoscopy and intubation has been investigated.
Prospective observational study in 40 adult critically ill patients. Patients were eligible if they were mechanically ventilated with an FiO2 ≤0.5 and PaO2/FiO2 ≥200 mmHg and hemodynamically stable with a hemoglobin ≥9 g/dL, no acute bleeding or need for blood transfusions, no renal failure, no chronic obstructive pulmonary disease. Twenty patients (hyperoxia group) underwent a 2-hour exposure to normobaric hyperoxia (FiO2 1.0), 20 patients were evaluated as controls. Serum erythropoietin (EPO) was measured at baseline, 24h and 48h. Serum Glutathione (GSH) and reacting oxygen species (ROS) were assessed at baseline (t0), after 2 hours of hyperoxia (t1) and 2 hours after the return to baseline FiO2 (t2). Sidestream dark field videomicroscopy was applied sublingually to assess the microvascular response to hyperoxia. Near infrared spectroscopy with a vascular occlusion test was applied at t0, t1, t2.
The standard anesthetic care plan for people having adolescent idiopathic scoliosis surgery will be accompanied by a pharmacokinetic simulation of the administered drugs to suggest opportunities to adjust drug doses to achieve tolerable pain control after surgery, avoid respiratory depression and allow patients to respond quickly either during intraoperative testing or at the conclusion of surgery.
There is currently a consensus that non-invasive ventilation (NIV) in preterm infants is preferred over intubation. There are two ways of delivering NIV in preterm infants, nasal continuous positive airway pressure (CPAP) or nasal intermittent positive pressure ventilation (NIPPV), where ventilator inflations are delivered intermittently over a fixed end-expiratory pressure. The synchronization in conventional mode is very difficult to obtain in premature infants. In all ventilation modes PEEP (end-expiratory pressure) is fixed. Considering that preterm infants are more likely to develop atelectasis, an active and ongoing management of the PEEP is very important to prevent de-recruitment. A new respiratory support system (NeuroPAP) was developed to address these issues (synchronization problems and control the PEEP). It uses the electrical activity of the diaphragm (EDI) to control the ventilator assist continuously, both during inspiration (principle of NAVA mode) and also during expiration (based on tonic Edi level).
Purpose of the Study: (1) To classify an individual subject's ventilatory response in terms of respiratory depression to a bolus of remifentanil under normoxic and hyperoxic conditions. (2) Measurement of specific respiratory parameters to predict the opioid-induced respiratory depression (OIRD) response.
This study evaluates the impact of the assisted mode of mechanical ventilation on diaphragm efficiency in mechanically ventilated critically ill patients. Participants will be randomized to the neurally adjusted ventilatory assist (NAVA) mode or to the pressure support ventilation (PSV) mode.
