Filter by:Background: Every year 30,000 Danish patients are admitted to Intensive Care Units (ICU), accounting for 2-3% of all patients in hospital and 30% of the yearly hospital expenditure. The mortality in the ICU is 12.7 % and the 30-day mortality is 21.2 % according to the national Danish Intensive Care Database. Through many years, the standard care has been to use continuous sedation of critically ill patients during me-chanical ventilation. However, recent research indicates that it is beneficial to reduce the sedation level in these patients. A randomised trial found that continuous sedation with a daily wake-up trial compared to continuous sedation reduced the time on me-chanical ventilation and the length of stay in the intensive care unit. Further, a ran-domised trial comparing continuous sedation with a daily wake-up trial to no sedation found that patients in the non-sedated group needed mechanical ventilation for a shorter time and had a shorter length of stay in the ICU and in the hospital. The trial also indicated a beneficial effect on mortality, however the trial was not a priori de-signed or powered with respect to mortality. No randomised trial has been published comparing sedation with no sedation, a priori powered to have all-cause mortality as primary outcome. Objective: To assess the benefits and harms of non-sedation versus sedation with a daily wake-up trial in critically ill patients in ICU. Design: The NONSEDA trial is an investigator-initiated, randomised, clinical, parallel-group, multinational, superiority trial designed to include 700 patients from at least six ICUs in Denmark, Norway and Sweden. Inclusion criteria: Mechanically ventilated patients with expected duration of me-chanical ventilation > 24 hours. Exclusion criteria: non-intubated patients, patients with severe head trauma, coma at admission or status epilepticus, patients treated with therapeutic hypothermia, patients with PaO2/FiO2<9 where sedation might be necessary to ensure sufficient oxygenation or place the patient in prone position. Experimental intervention: Non-sedation supplemented with pain management during mechanical ventilation. Control intervention: Sedation with a daily wake-up trial. The primary hypothesis is that non-sedation compared to sedation and a daily wake-up trial will reduce mortality. The secondary hypotheses are that non-sedation compared to sedation and a daily wake-up trial will: - Reduce the incidence of a composite outcome of death, acute myocardial in-farction (AMI), stroke, pulmonary embolism and other thromboembolic events. - Reduce the number of organ failures. - Increase the days alive without mechanical ventilation. - Increase the days alive outside the ICU. - Increase the days alive outside the hospital. Outcomes: The primary outcome is all-cause mortality at 90 days. Secondary out-comes are time to death in the trial period, the frequency of the trombo-embolic com-plications, acute renal failure, days alive without mechanical ventilation, days alive outside the ICU and hospital. Explorative outcomes are mortality at 28 days, organ failure and coma-free, delirium-free days. Trial size: The investigators will include 700 participants (2 x 350) in order to detect or reject 25% relative risk reduction in mortality with a type I error risk of 5% and a type II error risk of 20% (power at 80%).
Mesquida, J et al showed there was a significant linear correlation between pulse pressure variations under tidal volume 6 ml/kg and 8 ml/kg in patients after the resuscitation phase of severe sepsis and septic shock. No study revealed the actual relationship between various PPV under different VT. So we hypothesized that there were relationship between various PPV in different tidal volume settings. The objective of this study was to examine the relationship between various PPV.
This multi-site, randomized trial was conducted to determine the safety and effectiveness of a higher dose of vitamin A and determine if this would increase the rate of survival without bronchopulmonary dysplasia (BPD) and reduce the risk of sepsis. Infants with birth weights from 401-1000g and who were on mechanical ventilation or supplemental oxygen at 24-96 hours of age were enrolled. Subjects were randomized to either the Vitamin A or a control group. Infants in the Vitamin A group were given a dose of 5000 IU (0.1 ml) intramuscularly on Mondays, Wednesdays, and Fridays for four weeks. Control infants received a sham procedure rather than placebo injections.
The leakage of oropharyngeal secretions around high-volume low-pressure tracheal tube cuffs is usually considered as a major risk factor for bacterial tracheal colonization and subsequent development of ventilator-associated pneumonia. The rate of leakage around the cuff is related to the pressure differential across the cuff, namely the difference between the pressure of the subglottic fluid above the cuff and the tracheal pressure under the cuff. Consequently, positive end-expiratory pressure (PEEP) improves the sealing around the cuff towards fluid leakage. However, this preventive effect of PEEP is compromised during prolonged mechanical ventilation by tracheal suctioning manoeuvre, which may enhance fluid leakage, by decreasing tracheal pressure. Indeed, in a benchtop model, a suctioning manoeuvre, without disconnection of the ventilator, induced a constant fluid leakage past a high-volume low-pressure tracheal tube cuff when performed with a high level of suction pressure (- 400 mbar) and a large size of suction catheter size (16 French).
The purpose of this study is to compare two physiotherapy techniques: chest wall compression versus chest wall compression plus increase of 10 cmH2O in inspiratory pressure.
Almost all critically ill children who are mechanically ventilated require sedation and analgesia. Providing effective sedation for children in the PICU requires careful balancing of the need for sedation with the adverse effects associated with sedative medications. Clonidine is often used as an adjunctive sedative and analgesic in children but a well designed and adequately powered randomized trial is required to test the effect of clonidine-based sedation. Because there are no large randomized trials of sedation related interventions among critically ill children there are many unknown factors. This pilot trial, focussing on feasibility outcomes will assess the feasibility of, and inform the design of, a larger randomized controlled trial which will focus on clinically important outcomes.
Patients undergoing intubation and mechanical ventilation require removal of secretion by means of trachoebronchial suctioning. Timing of the procedure is mainly based on clinical parameters. TBA Care® is a new commercially available device designed to generate a signal when secretions are present in the respiratory tract of intubated patients, thus indicating the need for endotracheal suctioning only when necessary and prior to clinical deterioration. In a prospective randomized trial in intubated and mechanically ventilated patients of a general ICU the researchers investigated the efficacy of TBA Care® in detecting the presence of retained secretions compared to the standard indicators.
Objective: To compare termination criteria (TC) of pressure support ventilation (PSV). Design: Randomized cross-over clinical trial. Setting: Intensive Care Units. Patients: Sixteen patients on PSV with ability to answer a visual analog scale (VAS). Protocol and Measurements: Each patient was ventilated with two different TC ventilators, fixed and automatic, with measurements of ventilatory mechanic variables, breathing comfort and asynchrony patterns.
During weaning from mechanical ventilation process, the energy expenditure in T tube is greater than pressure support ventilation.
Sedation is widely used in mechanically ventilated patients. Propofol, benzodiazepines and opioids are the most used drugs. The study hypothesis is that sedation with remifentanil (an opioid drug) could improved respiratory pattern and effort in mechanically ventilated patients with rapid shallow breathing or high respiratory rate.
