Filter by:The purpose of this study is to assess whether circulating Angiotensin (Ang) II and Ang (1-7) levels are associated with right ventricular (RV) dysfunction in mechanically ventilated subjects. It is also designed to further characterize the subject population for severity of RV dysfunction. This study will investigate the association of renin-angiotensin system (RAS) peptides and markers of RV function, as measured by echocardiography, in subjects requiring acute mechanical ventilation. Maximum 150 subjects will be enrolled for the study and they will be evaluated over three days period using standard of care investigations, including trans-thoracic echocardiography (TTE) and/or trans-esophageal echocardiography (TOE) echocardiography. The maximum total duration of this study for subjects is 28 days.
The aim of study is to determine if 99mTc Annexin V-128 (AxV- 128/Tc) single photon emission computed tomography (SPECT)-computed tomography (CT) can detect perioperative lung injury. The investigators will study patients undergoing major surgery, specifically Whipple procedures (pancreatico-duodenectomies) and compare AxV-128/Tc SPECT-CT scans before and after surgery in Chronic Obstructive Pulmonary Disease (COPD) and non-COPD patients.
The purpose of this study is to collect physiologic data from patients with severe brain injury who require mechanical ventilation in order to describe the impact of ventilation, specifically positive end expiratory pressure (PEEP), on intracranial pressure (ICP).
Severe radiation-induced lung injury (RILI) occurs in approximately 20% of the lung cancer patients, who are treated with curative chemoradiation. In this study the investigators want to evaluate the prognostic value of baseline cardiac function assessed with echocardiography for prediction of RILI.
The purpose of the study is to assess the time, dose dependence, and fraction-size dependence of radiation (RT)-induced changes in regional lung and heart perfusion/function/structure following thoracic RT delivered using newer IMRT/conformal/radiosurgery techniques. The PI hopes to develop models to better relate and predict RT-induced changes in regional lung and heart perfusion/function/structure with changes in global cardiopulmonary function. Patients will undergo pre- and serial post-RT lung and heart assessments to better understand RT-induced regional heart/lung changes.
Lung injury in patients undergoing oesophagectomy may occur during surgery (peri-operatively) as a result of One Lung Ventilation (OLV) and/or during the immediate post-operative period when patients receive intensive care. This is reinforced by the observation that physiological markers of lung injury are most elevated immediately after completion of surgery, and the development of clinical Acute Respiratory Distress Syndrome (ARDS)occurs immediately post-operatively (within 72 hours of surgery), with the majority of cases reported 24-48 hours after completion of surgery. This study is designed to investigate the impact of pre-operative administration of GSK2862277 on biological and physiological markers of lung injury in patients undergoing surgical resection of oesophageal cancer in order to achieve optimal exposure at the site of injury following OLV and lung deflation. This study is a randomized placebo controlled, double-blind, multi-centre, single dose parallel group, design. There will be two treatment groups comprising one active and one placebo arm with approximately 40 patients per group. Patients enrolled in the study will be scheduled to undergo planned/elective trans-thoracic surgery for oesophagectomy. The primary endpoint for this study is the change in pulmonary vascular permeability index (PVPI) from pre-surgical levels to the end of surgery. GSK2862277 will be administered as an orally inhaled aerosol (single nebulized dose) over approximately 3 to 5 minutes (min) 1-3 hours prior to surgery. Subject will be monitored daily until discharge and followed up till day 28.
The investigators propose a prospective randomized clinical trail to evaluate the impact of intensive medical nutrition therapy (IMNT) in patients with acute respiratory distress syndrome (ARDS) or acute lung injury (ALI) on short and long-term outcomes. Participant's (N = 200) will be randomized to receive either standard care (SC e.g. ad lib feeding of standard food) or IMNT provided early as enteral nutrition (EN) and continued as intensive diet therapy tailored to maximize oral intake until hospital discharge. Primary outcomes evaluated include infections while hospitalized, immune parameters (CD4 and CD8 cells, serum IL-10 and leptin levels, numbers of T regulatory cells and markers for T cell anergy), days on mechanical ventilation, in the ICU and hospital , and changes in fat free mass(measured by dual energy x-ray absorptiometry), weight, muscular weakness (measured as hand grip strength), fatigue (measured as distanced traveled in 6-minute walk) and pulmonary function.
This study will compare two ventilator modes in mechanically ventilated patients with acute lung injury. Acute lung injury (ALI) is a condition in which the lungs are badly injured and are not able to absorb oxygen the way healthy lungs do. About 25% of patients who are ventilated get ALI. ALI causes 75,000 deaths in the US each year. Ventilators can be set to work in different ways, called modes. One mode, called ARDSNet, pumps a small amount of air into the patient's lungs and then most of the air is released prior to the next breath. Another mode, called Airway pressure release ventilation (APRV), keeps air in the lungs longer between breaths. Both of these modes are currently used at this hospital. The investigators think APRV may help patients with ALI, but we do not know for sure.
Aim is to investigate the influence of an early supply of parenteral nutrition including a fish oil containing lipid emulsion on the course of acute lung injury in the intensive care unit. In comparison, a standard parenteral nutrition with a soybean oil based emulsion will be used. Data obtained in this trial may provide evidence for a beneficial effect of fish oil derived omega-3 fatty acids in parenteral nutrition regarding their influence on acute lung injury.
In 2008 a new ventilation strategy termed variable Pressure Support ventilation (PSV) was introduced, which is able to increase the variability of the respiratory pattern independent from the inspiratory effort. In experimental lung injury, variable PSV was found to improve gas exchange and decrease the inspiratory effort, while reducing alveolar edema and inflammatory infiltration compared to conventional(non-variable) PSV. Importantly, variable PSV reduced peak airway pressure and respiratory system elastance in a variability dependent manner.In addition, preliminary observations suggest that variable PSV can reduce the work of breathing and improve patient comfort, but it is not known whether this new ventilatory strategy is able to speed the weaning from mechanical ventilation. Since variable PSV can reduce the mean pressure support, it may lead to a faster reduction of pressure support and, therefore, a shorter weaning period than conventional PSV. The hypothesis of this study is that variable pressure support ventilation reduces the duration of mechanical ventilation to non-variable (conventional) pressure support ventilation.
