Filter by:Elective open aortic aneurysm repair has an overall reported 30 day mortality of 2-6 percent, but in patients more than 65-70 years the mortality is reported to be more than 10 percent. The phenomenon of acute lung injury (ALI)/adult respiratory distress syndrome (ARDS) after infra renal abdominal aneurysm repair caused by ischemia-reperfusion is well established. The degree of disability varies from a light degree of acute respiratory failure to mortality for patients with the same profile of risk. Primary aim is to develop a model that monitors inflammatory marker molecules collected from the bronchial epithelial lining fluid by microdialysis. The method with examination of the bronchial epithelial lining fluid by microdialysis and analysis of multiple inflammation markers as previously done by the investigators group.
Patients with severe lung conditions occasionally require support with a special ventilator (breathing machine) called the High Frequency Oscillator (HFO). Effective ventilation requires that the pressure generated by the ventilator be as high as possible but not too high as this can damage the lungs. In patients on HFO, there is not a well defined way to measure this pressure. We will insert a small probe into the esophagus of patients on HFO to see if this is an accurate way to measure lung pressures for these patients. A better understanding of these pressures could lead to improved patient care.
The aim of the study is to compare, in patients with acute respiratory failure/acute lung injury the efficacy of three different methods of oxygenation to prevent endotracheal intubation : 1. conventional oxygen therapy (O2 conventional) 2. high flow nasal oxygen therapy (O2-HFN) 3. association of high flow nasal oxygen therapy with non invasive positive pressure ventilation (O2-HFN/NPPV).
The purpose of this study is to determine whether ischemic preconditioning reduces lung injury in patients undergoing pulmonary resection.
Severe sepsis/septic shock is a serious condition associated with high mortality rate. Hydrocortisone has been recommended as a useful treatment to decrease mortality in hemodynamically unstable septic shock patients, not response to fluid and moderate dose of vasopressor. During the progression of severe sepsis/septic shock, multi-organ dysfunction can develop. Acute lung injury (ALI) and its more severe form, acute respiratory syndrome (ARDS) is one of the common organ dysfunction associated with septic shock. Information from a meta-analysis suggested that moderate dose of hydrocortisone may improve the ARDS patients' outcome. Whether hydrocortisone can effectively prevent disease progression and death in severe sepsis/septic shock patients who complicated with ALI/ARDS has not been proven.
This study will examine the hypothesis that iloprost maintains and improves ventilation perfusion matching in patients with pulmonary hypertension and ARDS/ALI as reflected by 1) an improved PaO2/FIO2 ratio as calculated from the measured arterial blood gases obtained before and after iloprost administration, 2) an improvement in lung compliance, and 3) an improvement in the ventilatory equivalents for oxygen and CO2 measured by expired gas analysis.
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.
RAGE, the receptor for advanced glycation end products, is a novel marker of alveolar epithelial type I cell injury. Soluble RAGE (sRAGE) is elevated in the plasma and in the pulmonary edema fluid from patients with ALI/ARDS, but one should acknowledge that the RAGE/NF-B axis is also involved in the pathophysiology of various other conditions. Few data are available about the levels of soluble forms and ligands of RAGE in the setting of ALI/ARDS. The purpose of this observational prospective study is to describe soluble forms (sRAGE, esRAGE) and ligands of RAGE (HMGB-1, S100A12, AGEs) levels in ICU patients with ALI/ARDS.
Remote Ischemic Preconditioning (RIPC) is a treatment that may be associated with improved outcomes after cardiac surgery. It can be elicited noninvasively by using a tourniquet to elicit transient ischemia over a lower extremity. It is thought to promote anti-inflammatory and cell survival pathways, and thus protect remote organs against future ischemic injury. We hypothesize that compared to sham treatment, RIPC will be associated with decreased post-operative acute kidney, myocardial, and lung injury.
The purpose of this trial is to determine whether low tidal volume during intraoperative one-lung ventilation could decrease the incidence rate of postoperative acute lung injury compared to "normal" tidal volume.
