Filter by:The purpose of this study is to compare the effect of an early and integral communication strategy (EICS) versus standard care, on the rate of depressive symptoms at 3 months after discharge from the ICU, in patients with severe Covid-19, their family members and health personnel. Evaluating the rate of depressive symptoms at 3 months after discharge from the ICU, with a) Hospital Anxiety and Depression, b) Posttraumatic Stress Disorder Checklist (S)
Background: For patients with out-of-hospital cardiac arrest (OHCA) at the intensive care unit (ICU), oxygen therapy plays an important role in post resuscitation care. During hospitalisation, a lot of these patients occur with pulmonary arterial hypertension (PAH). Currently a wide oxygen target is recommended but no evidence regarding optimal treatment targets to minimise the prevalence of PAH exists. Methods: The RELIEPH trial is a substudy within the BOX (Blood pressure and OXygenation targets in post resuscitation care) trial. It is a single-center, parallel-group randomised controlled clinical trial. 300 patients with OHCA hospitalised at the ICU are allocated to one of the two oxygenation interventions, either a restrictive- (9-10 kPa) or liberal (13-14 kPa) oxygen target both within the recommended range. The primary outcome is the fraction of time with pulmonary hypertension (mPAP >25 mmHg) out of total time with mechanical ventilation. Secondary outcomes are: length of ICU stay among survivors, lactate clearance, right ventricular failure, 30 days mortality and plasma brain natriuretic peptide (BNP) level 48 hours from randomisation. Discussion: This study hypothesises that a liberal target of oxygen reduces the time with PAH during mechanical ventilation compared to a restrictive oxygen target in patients with OHCA at the ICU. When completed, this study hopes to provide new knowledge regarding which oxygen target is beneficial for this group of patients.
Pressure support ventilation (PSV) is the most commonly used mode in mechanical ventilated patients. Studies have shown that over-assistance was prevalent in patients undergoing PSV. Up to now, no reliable method has been recommended to select an "optimal" inspiratory support level. Pressure muscle index (PMI) was introduced recently to evaluate the degree of spontaneous breathing effort. We hypothesize that PMI might be used as an indicator for over-assistance during PSV. In this randomized crossover study, inspiratory support is set at three levels according to negative, positive and zero PMI. Inspiratory effort, work of breathing, and respiratory mechanics are compared among the three inspiratory pressure support levels.
To verify whether remifentanil is more beneficial to reduce the duration of mechanical ventilation, shorten the interval from SBT to extubation, reduce the incidence of adverse events, reduce the workload of nursing staff, reduce the dosage of sedatives and ICU hospitalization costs, shorten the length of ICU hospitalization, and reduce the short-term mortality.
In this study, the investigators will study music therapy for patients during breathing trials, a procedure performed in intensive care units. Participants will be assigned either to standard medical care or standard medical care plus music therapy. Participants have a 50/50 chance (like flipping a coin) of being in either group. In the music therapy group, a board-certified music therapist will sing softly with guitar accompaniment to provide music during the breathing trial. The music is in addition to the usual treatment provided by hospital staff. Participants in the standard medical care group will receive the usual medical care given by hospital staff members. Information will be collected from participant's charts and by observation of vital signs during the breathing trial.
In this study, the investigators propose to explore the hemodynamic variations induced by vasopressin and its influence on cardiac output, mean systemic pressure, and venous return resistance measured through cardiopulmonary interactions, according to the approach proposed by Guyton, in patients undergoing major abdominal surgeries.
Delirium is common in septic patients, especially those receiving mechanical ventilation in the intensive care unit (ICU). Dexmedetomidine is a highly selective α2 adrenoreceptor agonist with anxiolytic, sedative, analgesic, and anti-inflammatory effects. Use of dexmedetomidine in mechanically ventilated ICU patients is associated with less delirium and improved outcomes. However, dexmedetomidine infusion produces dose-dependent bradycardia and hypotension; these limited the use of dexmedetomidine in ICU patients. This study is designed to test the hypothesis that low-dose dexmedetomidine infusion can also reduce delirium in mechanically ventilated ICU patients with sepsis.
Ventilator-associated pneumonia (VAP) refers to a lower respiratory tract nosocomial infection acquired >48h after being intubated in Intensive Care Units. Pathogenesis of VAP is mechanical and associated with microaspiration and leakage of oropharyngeal secretions around the endotracheal tube. A novel approach to VAP will attempt to explore how the abrupt ecological order of acute infection (high bacterial biomass, low community diversity) emerges from the dynamic homeostasis of a pre-existing ecosystem in which lung microbiota and local immunity interaction play their essential role. Therefore, the investigators aim to explore if oral and lung microbiota modifications with local immunity changes, contribute in the pathogenesis of VAP in patients intubated for non-pulmonary reasons. Early changes in the host microbiota with the innate immunity system impairs tissue homeostasis and may represent a new distinct condition and a potential tool for early diagnosis and prevention of VAP.
Several studies suggest fully-automated ventilation to ventilate with a lower amount of MP in unselected ICU patients, patients after cardiac surgery, and patients with and without ARDS. The current study will directly compare the amount of MP in invasively ventilated critically ill patients by calculating MP breath-by-breath, using the various equations proposed in the literature.
In this study, we intend to examine the effectiveness of an indirect calorimetry-guided nutrition plan, compared to the conventional, RDI-guided nutrition plan in mechanically ventilated patients, in terms of success rates of prolonged ventilation weaning, and shorter weaning time period. Hypotheses: The rates of chronically ventilated patients weaned off invasive ventilation will increase by 15% in the intervention group, and the average weaning period in this group will be reduced by 10 ± 4 days. Methods: A randomized controlled intervention trial that will include 200 chronically ventilated patients, admitted to the "Reuth" Rehabilitation Hospital, who meet the criteria for weaning from prolonged mechanical ventilation. Patients in the intervention group (n=100) will undergo precise calorimetric measurements using indirect calorimetry and will be administered with a nutrition plan in accordance with these measurements. Nutrition plans of patients in the control group (n=100) will be calculated and administered according to current RDI conventions (up to 24 Kcal/kg/day). In order to assure blinding, patients in the control group will undergo the same calorimetric measurements using indirect calorimetry, however, these results will not be used in any way to determine or influence the nutritional plan.
