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.
Acute respiratory distress syndrome (ARDS) is a devastating form of acute lung inflammation, that may be caused by a variety of insults with pulmonary and systemic infectious disease being the most common predisposing factor. Sepsis, on the other hand, represents the systemic inflammatory response to an invading pathogen, which may inflict damage upon the host through organ dysfunction. ARDS and sepsis are heterogenous clinical conditions that have a high mortality, and both diseases involve a complex interplay of different inflammatory mediators and cell types. It has been suggested that locally released inflammatory mediators pass from the lungs into the bloodstream following ARDS, triggering systemic inflammation. Conversely, it is possible that severe systemic inflammation may lead to ARDS by an influx of inflammatory mediators from the bloodstream to the lungs. However, the time course and the possible pathways for this transmission of disease have yet to be established. Investigators hypothesize that: 1. Primary systemic inflammation is followed by a secondary pulmonary inflammatory response 2. Primary pulmonary inflammation is followed by a secondary systemic inflammatory response 3. Both primary and secondary inflammatory responses are characterized by the appearance of pro-inflammatory cytokines, inflammatory cells and production of collagen-like proteins (termed 'lectins') 4. The inflammatory response is most pronounced in the primary afflicted compartment.
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.
A certain molecule floating in the blood may represent a risk of lung injury after a transfusion. We are determining whether detection of this molecule on a simple blood clotting test will predict the development of lung injury due to transfusion in bleeding patients with chronic liver disease.
Assessment of the effect of hyperoxia and hypertonic saline on survival in patients with septic shock Hyperoxia and hypertonic saline may have beneficial effects on organ perfusion and oxygenation and may reduce the organ failure occurences. To date, only scarce data are available. Side effects are not well described. Therefore we designed a randomized clinical trial in order to assess the early administration of hypertonic saline and oxygen in the very early beginning of septic shock.
This study evaluates the use of nebulized hypertonic saline (aerosolized salt water) as a preventive treatment for post-traumatic acute lung injury (ALI). Both animal and human research indicate that aerosolized salt water might help reduce harmful inflammation with minimal risks.
Some people develop the condition called acute respiratory distress syndrome (ARDS). This is a condition where the lungs have become injured from one of a number of various causes, and do not work as they normally do to provide oxygen and remove carbon dioxide from the body. This can lead to a reduced amount of oxygen in the patient's bloodstream. Patients with ARDS are admitted to the intensive care unit (ICU) and need help with their breathing by being connected to a ventilator (breathing machine). ARDS can lead to injury in other organs of the body causing other problems but also death. Over the past few years, reducing the size of each breath delivered by the ventilator in conjunction with the use of an occasional sustained deep breath called a "recruitment manoeuvre" have been used to try to prevent further damage to the lungs in people with ARDS. This ventilator strategy (termed the PHARLAP strategy) has been shown in a small research study to have some beneficial effects without causing any obvious harm, when compared to a current best practice ventilator strategy. The main beneficial effects of the PHARLAP strategy were to increase the amount of oxygen in the blood and to reduce markers of inflammation (the body reacting to a disease process) in the body. This study was too small to make a strong conclusion, so this study will be much larger and will assess whether patients who have developed ARDS are better off when we use the PHARLAP strategy. Three hundred and forty patients will be enrolled into this study in multiple ICUs across Australia and New Zealand. The study hypothesis is that the PHARLAP strategy group will have a higher number of ventilator free days at day 28 than the control group.
