Active clinical trials for "Lung Injury"

To observe changes of circulating and tissue dendritic cells in acute lung injury,including invasive aspergillosis pneumonia

When a person is put on a breathing machine the investigators think that the breathing muscles can get weaker. The investigators are not sure how quickly this happens but in some people this leads to problems when they try to breathe on their own without the breathing machine. The diaphragm is at the bottom of a person's chest separating their lungs from what is in their belly and it is a very strong muscle. In fact, it is main muscle that one uses for breathing. An ultrasound machine is a painless way to see what is happening beneath the skin. It is safe and easy to do. Using an ultrasound the investigators are planning to measure how thick the diaphragm is and how much it changes while a person is on a breathing machine in the ICU. Getting a better understanding of this condition could lead to improved treatments that might help support patients who require a ventilator for breathing. The investigators hypothesis is that patients for whom the breathing machine is doing all of the work of breathing, will have their diaphragm thickness gradually decrease and changing to a breathing modem mode where they have to put in more effort the diaphragm thickness will start increasing again.

To study the association of the thoracic fluid content and acute lung injury during liver transplantation.

The influenza A/H1N1v pandemic virus causes severe pneumonia that can lead to acute respiratory distress syndrome and death even in healthy young individuals. The respective roles of viral replication, bacterial infection and immune alterations of the host during such severe influenza H1N1v infection need to be clarified in order to optimize patients care. In this context, we aim to study immune and virological parameters in bronchoalveolar lavage fluid during severe influenza A/H1N1v infection with pulmonary involvement in intensive care unit. Results will be correlated to bacterial or viral pulmonary co-infections and to peripheral blood immune and virological parameters.

The investigators aim to compare four different lung recruitment techniques (described in literature) to Computed tomography scan analysis.

The investigators aim to compare the respiratory mechanics in acute lung injury (ALI)/acute respiratory diseases syndrome (ARDS) patients with and without pleural effusion.

PALIVE 1 is an observational multicenter study on mechanical ventilation strategies used in children with an acute lung injury (ALI). The objective of the study is to describe mechanical ventilation strategies in children with an ALI. Our hypothesis is that daily clinical practice is heterogenous among pediatric intensivists as few pediatric data exists on optimal mechanical ventilation strategies in this group of patients. Furthermore, different strategies may affect patient outcome.

Bedside lung ultrasonography helps to obtain reliable clinical information about lung aeration, that has been categorized by means of the so-called lung ultrasound score (LUS). In critically ill adults, LUS has been related with the outcome both in patients with respiratory and some non-respiratory conditions. Pediatric studies about lung aeration have been done mainly on postoperative cardiac patients and infants with bronchiolitis. In this prospective, observational, multicenter, feasibility and diagnostic accuracy study, we will explore the degree of lung aeration impairment as a potential outcome predictor in critically ill children with a variety of underlying conditions. Children from 1 month to 18 years of age admitted to PICU will be recruited and LUS will be calculated at two time points: at 12 ± 6 hours and at 48-72 hours. Univariate and multivariate statistical analysis will be performed in order to ascertain the outcome influence of clinical factors in general and LUS in particular.

Hypothesis of the study is that patients undergoing major cardiac surgery can develop extracardiac complications correlated to cardiopulmonary by pass.

The purpose of this study is to examine changes in ventilation and airway pressures during conventional bronchoscopy of intubated patients.
