Filter by:Proof-of-concept study addressing the feasibility of awake ECMO (v/v) in patients with acute respiratory failure
The purpose of this study is to demonstrate that mechanical ventilation guided by the diaphragm EMG signal (also know as neurally adjusted ventilatory assist [NAVA]) is superior compared to pressure support and pressure control ventilation.
Electrical impedance tomography (EIT) monitoring has been researched as a method to determine the spatial impedance distribution in a body cross section, but has yet to become an established clinical tool. EIT monitoring gives a dynamic, breath-to-breath measurement of both global and regional ventilation. Recently, there has been evidence that EIT monitoring has great potential to become a non-invasive bedside tool for assessment of regional lung ventilation without documented hazards. Potential applications include any adult patients in acute respiratory failure. Data collected from this research may contribute to improved patient safety outcomes. PURPOSE: The purpose of this pilot study is to examine the feasibility of using the EIT monitor in intensive care unit (ICU) setting on patients with acute respiratory failure and to compare the EIT monitor data to standard of care patient assessments. It is hypothesized that the EIT monitor, when applied to adults in acute respiratory failure, will correlate with conventional standard of care assessments for these patients.
As medicine advances, many lives can be saved in the intensive care unit. However, when multiple organ failure occurs, the mortality rate of patients increases dramatically. Therefore, the major goal in the intensive care unit is to prevent the occurrence of multiple organ failure. The sepsis protocol and early goal directed treatment have great effects to reduce development of multiple organ failure and to decrease the mortality rate. However, sometime the condition of patient deteriorated in spite of both the mean blood pressure and mixed venous oxygen saturation are normal. Some experts recognize that there might be microcirculatory dysfunction of tissue or organ. The dysfunction of microcirculation might due to vasoconstriction or microthrombosis. Vasoconstriction might result from systemic inflammation, reactive oxygen species, or dysfunction of synthesis of NO (nitric oxide). Microthrombosis might result from systemic inflammation, reactive oxygen species, imbalance of coagulatory system, or damage of endothelial cell. In clinical practice, the oxidative stress is related to circulatory shock, sepsis, acute lung injury, and acute respiratory distress syndrome. This study tries to investigate the relation between oxidative stress and microcirculation. Furthermore, the investigators will try to investigate the correlation between the severity of oxidative stress and microcirculatory dysfunction and the severity of disease and prognosis. The investigators hope this study will help them to figure out the picture of disease progression of patients. It may conduct further study to modulate the oxidative stress, to improve the microcirculatory function, and finally to improve the outcome of patients.
By examining the intraoperative anesthetic characteristics of patients who developed ARDS postoperatively, we hope to identify variables which have a positive or negative association on the development of ARDS.
The use of neuromuscular blocking agents (NMBA) in ARDS patients has not been extensively investigated. The aim of the study is to show a reduction of the mortality rate of ARDS patients.
The investigators aim to compare the respiratory mechanics in acute lung injury (ALI)/acute respiratory diseases syndrome (ARDS) patients with and without pleural effusion.
The purpose of this study is to determine the effects of variable ventilation on respiratory system of patients affected by acute respiratory distress syndrome.
The investigators aim to study the specific elastance in ALI/ARDS patients during invasive mechanical ventilation.
