Active clinical trials for "Respiratory Insufficiency"

Obesity is a significant health care issue in the United States, particularly among the critically ill. Preliminary research has shown that differences in ventilator management exist among obese and non-obese individuals. This study will examine the effect of excess weight on ventilator management and clinical outcomes in individuals in an intensive care unit (ICU).

The purpose of this study is to determine whether immunonutrition and pre operative nutrition can reduce lenght of respirator support, lenght of stay in the ICU and incidence of post operative infections

In this randomized cross over study the investigators will evaluate the effects on gas exchange and patients' tolerance of a new CO2 non rebreathing devices incorporated in the mask vs the traditional mask COPD patients undergoing NIV for an episode of Acute Hypercapnia Respiratory Failure, will be randomized after at least 12 hour of ventilation to 1 h.trial with the usual full face mask or the same mask with the addition of a new CO2 clearance device

Analgo-sedation is standard procedure in anesthesiology practice and is often given for colonoscopy in the setting of daily hospital. Ideally, patients should be sedated with preserved spontaneous breathing and adequate blood O2 saturation. To maintain adequate oxygenation, low-flow O2 (2-6 L/min) is usually delivered through standard nasal catheter which can provide inspired fraction (FiO2) of 40% (low-flow nasal oxygenation - LFNO). Coldness and dryness of LFNO applied may be uncomfortable to patient. Standardly applied intravenous anesthetics can lead to transient ceasing of breathing and O2 desaturation despite LFNO. Respiratory instability can also potentiate circulatory instability - undesirable changes in heart rate (HR) and blood pressure (BP). Unlike LFNO, high-flow heated and humidified nasal oxygenation (HFNO) is characterized by the oxygen-air mixture flow of 20 to 70 L/min up to 100% FiO2. Warm and humidified O2, delivered via soft, specially designed nasal cannula, is pleasant to patient. HFNO develops continuous positive pressure of 3 to 7 cmH2O in upper airway which enables noninvasive support to patient's spontaneous breathing thus prolonging time of adequate O2 saturation. Aim of this study is to compare effect of HFNO and LFNO on oxygenation maintenance before, during and after standardized procedure of intravenous analgo-sedation in normal weight patients of ASA risk I, II and III. Investigators hypothesize that application of HFNO compared to LFNO, in patients with preserved spontaneous breathing during procedural analgo-sedation, will contribute to maintaining of adequate oxygenation, consequentially adding to greater circulatory and respiratory patients' stability. Investigators expect that patients who receive HFNO will better maintain adequate oxygenation regarding improved spontaneous breathing. Also patients will have shorter intervals of blood oxygen desaturation, less pronounced rise in blood CO2 level and lesser fall of blood O2 level, less change in HR and BP. Investigators will have to exactly estimate partial and global respiratory insufficiency (blood CO2 and O2 levels) associated with LFNO and HFNO, which will be done by blood-gas analysis of 3 arterial blood samples collected before, during and after analgo - sedation via previously, in local anesthesia, placed arterial cannula. Possible complications will be explained in written uniformed consent and by anesthesiologist.

The long-term goal of this research program is to improve understanding of the mechanistic link between Alzheimer's disease (AD) neuropathology, acute delirium, and cognitive impairment following acute respiratory failure. In this pilot study, the study team will establish a prospective cohort of older patients with acute respiratory failure and obtain data on delirium duration, AD imaging and CSF biomarkers, and cognitive outcomes following critical illness.

this study evaluates high flow oxygen therapy in addition to non invasive ventilation (NIV) to treat hypercapnic respiratory failure. Between sessions of NIV, half of participants will have high flow nasal cannula while the others will have standard low flow oxygen therapy.

Controlled mechanical ventilation may lead to the development of diaphragm muscle atrophy, which is associated with weakness and adverse clinical outcome. Therefore, it seems reasonable to switch to partially supported ventilator modes as soon as possible. However, in patients with high respiratory drive, the application of partially supported modes may result in high lung distending pressures and diaphragm injury. Recently, the investigators published a study that demonstrated that a low dose of neuromuscular blocking agents (NMBA) facilitates lung-protective ventilation and maintains diaphragm activity in intensive care unit (ICU) patients. That study was conducted in a small (N=10), selected group of patients and partial neuromuscular blockade was applied for only 2 hours (proof-of-concept study). Therefore, further research has to be done before this strategy can be applied in clinical practice. The primary goal is to investigate the feasibility and safety of prolonged (24 hours) partial neuromuscular blockade in patients with high respiratory drive in partially supported mode. The secondary goals are to evaluate the effect of this strategy diaphragm function, lung injury, hemodynamics and systemic inflammation.

The study will be performed as a randomized controlled non-inferiority trial. HFA has been increasingly used in the last years to treat hypoxic respiratory failure (i.e. type I failure), and numerous studies have shown its efficiency in this indication. Despite this good evidence for HFA in hypoxic respiratory failure, it has only reluctantly been used for hypercapnic respiratory failure. HFA has been shown to generate PEEP, despite not being a closed system, and to improve CO2 clearance by flushing anatomical dead space. It might also help to reduce inspiratory resistance and facilitate secretion clearance from humidified gas. A study on COPD patients showed an increase in breathing pressure amplitude and mean pressure, as well as tidal volume, with a trend towards reduction of carbon dioxide partial pressure. Intervention consists of HFA using standard equipment at the department. A gas flow of 60 litres per minute and a FiO2 as clinically feasible will be used. Therapy will be continued until a pCO2-level of 50 mmHg or less is reached, or therapy has to be aborted because of lack of tolerance by the patient or indication for intubation. Control consists of non-invasive continuous positive airway pressure ventilation support using a tight mask and standard respirator equipment of the Department of Emergency Medicine. A positive airway pressure of 3,67 mmHg and a FiO2 as clinically feasible will be used. Therapy will be continued until a pCO2-level of 50 mmHg or less is reached, or therapy has to be aborted because of lack of tolerance by the patient or indication for intubation.

Vibroacoustic pulmonary therapy in patients with COVID19 is believed to have a positive effect on oxygen status and a decrease in the duration of respiratory failure

According to recent data, death rate is more than 20% for 75 years old hospitalized patients and older. In case of aggravation, according to the latest observations, if they are refused for mechanical ventilation in intensive care, their death rate could reach 60% even for patients without comorbidity. Apart from an increase in oxygen therapy, no specific treatment is currently proposed. The control of the inflammatory component seems to be a key element to be able to influence the patients' health evolution. Polyvalent intravenous immunoglobilins have immunomodulatory and anti-inflammatory properties with a favorable safety profile for these elderly patients and several clinical cases lead to positive impact in the caring for Covid patients. This study objective is evaluation of the efficacy of polyvalent IVIg in combination with the standard management of patients aged 75 and over with SARSCov2 infection with acute respiratory failure (saturation ≤ 95%) requiring oxygen therapy> 5 L / min (i.e. patients considered as moderate to severe ARDS according to the Berlin definition, Pa02 / Fi02≤200) and disqualified from a care in the ICU.
