Effects of SEvoflurane on Gas Exchange and Inflammation in Patients With ARDS (SEGA Study)
Acute Respiratory Distress SyndromeNumerous trials support the efficacy and safety of volatile anesthetic agents, namely inhalation of sevoflurane through dedicated devices, for the sedation of ICU patients. Several preclinical studies have shown that sevoflurane inhalation improves gas exchange and decreases pulmonary and systemic inflammation in experimental models of acute respiratory distress syndrome (ARDS). The purpose of our prospective monocentric, randomized, controlled trial is to evaluate the effects of an early 48-hour sevoflurane inhalation on gas exchange and inflammation in patients with ARDS.
The Safety, Tolerability, PK and PD of GSK2586881 in Patients With Acute Lung Injury
Lung InjuryAcuteThis is an early phase (phase IIa), randomized, multi-center study in subjects with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). The purpose of this study is to investigate the safety of GSK2586881 and to determine what effects it has on people with Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS). The study has two parts: Part A will be an open-label investigation in five subjects. Part B will be a double-blind, placebo controlled investigation and will involve approximately 60 subjects.
Early Versus Delayed Enteral Feeding to Treat People With Acute Lung Injury or Acute Respiratory...
Respiratory Distress SyndromeAdultAcute respiratory distress syndrome (ARDS) and acute lung injury (ALI) are medical conditions that occur when there is severe inflammation and increased fluids in both lungs, making it difficult for the lungs to function properly. Hospital treatment for a person with ALI/ARDS often includes the use of a breathing machine, or ventilator, until the person is able to breathe without assistance. Initiating proper nutrition through a feeding tube early in a person's hospital stay may help to improve recovery, but the optimal timing, composition, and amount of feeding treatments remain unknown. This study will evaluate whether early or delayed full-calorie feeding through a feeding tube is more effective in reducing recovery time and increasing survival rates in people with ALI/ARDS.
Efficacy and Safety of a Lung Recruitment Protocol in Children With Acute Lung Injury
Acute Respiratory Distress SyndromeAcute Lung InjuryLung units which participate in gas exchange are known as 'recruited' lung. Patients with lung injury suffer from a proportion of units which do not participate in gas exchange (i.e. the derecruited state), which results in impaired gas exchange and induces an inflammatory cascade. Currently, there is no clinical practice guideline in our intensive care unit regarding lung recruitment strategies for children with lung injury. While many studies have demonstrated efficacy (ability to open the lung) and safety of recruitment maneuvers in adults, no such studies have been performed in children. The primary purpose of this study is therefore to demonstrate the safety and efficacy of a recruitment protocol designed to maximally recruit collapsed lung in children with acute lung injury. Each study patient will follow a recruitment protocol (see Appendix 2). Two 'controls' will be utilized in this study: baseline ventilation (no recruitment maneuver) and the open lung approach (a sustained inflation followed by increased PEEP). Efficacy will be defined as an improvement in lung volume (as measured by nitrogen washout and electrical impedance tomography), and by an improvement in measured arterial partial pressure of oxygen. Safety will be defined as the incidence of barotrauma and hemodynamic consequences which occur during the protocol. A secondary purpose of this study will be to further validate electrical impedance tomography (EIT) as a non-invasive tool describing the lung parenchyma by comparing it to an accepted standard method of measuring lung volumes, the multiple breath nitrogen washout technique. Validation of EIT would allow clinicians to have a non-invasive image of a patient's lungs without the risks imposed by radiography. The information we learn will be instrumental in defining an optimal strategy for lung recruitment in children with lung injury.
Evaluation of Variable Pressure Support Ventilation in the Therapy of Acute Lung Injury
Acute Lung InjuryVariable pressure support during assisted spontaneous breathing (noisy PSV) has been shown to improve the respiratory function in experimental acute lung injury (ALI). We aimed at comparing the effects of noisy PSV with traditional PSV on the respiratory function of patients suffering from ALI.
Stepwise Positive End Expiratory Pressure Elevation For Lung Recruitment in Acute Respiratory Distress...
Acute Respiratory Distress SyndromeAcute respiratory distress syndrome is a severe lung disease caused by a variety of direct and indirect issues. It is characterized by inflammation of the lung parenchyma leading to impaired gas exchange and persistent hypoxemia. This condition is often fatal, usually requiring mechanical ventilation. Recruitment maneuver aimed to enhance the effect of mechanical ventilation.The objective of this study was to compare safety and efficacy of two lung recruitment maneuvers.
Combined High Frequency Oscillation and Tracheal Gas Insufflation for Severe Acute Respiratory Distress...
Respiratory Distress SyndromeAdultIn the past five years, there is a growing body of published evidence on the feasibility, and oxygenation and lung protection benefits of high frequency oscillation (HFO) in the acute respiratory distress syndrome (ARDS). The investigators have recently demonstrated the short term feasibility and additional benefits with respect to oxygenation of HFO combined with tracheal gas insufflation (TGI). In the present clinical trial, the investigators intend to test the hypothesis that HFO-TGI may result in improved respiratory physiology and clinical course compared to low tidal volume conventional mechanical ventilation in patients with severe ARDS.
Prevention of Lung Edema After Thoracic Surgery
Lung InjuryAcute5 moreBackground : Acute lung injury (ALI) occasionally occurs after pulmonary resection and carries a bad prognosis with a high mortality rate ranging from 20 to 100%. Objectives : to evaluate pre-, intra- and postoperative changes in hemodynamics, oxygenation indices as well as intra- and extravascular lung water using simple thermodilution technique and continuous arterial pressure analysis to test the efficacy of inhaled beta2 -adrenergic agonist versus anticholinergic agents to reduce lung edema in patients undergoing thoracic surgery and in pigs subjected to lipolysacharide-induced ALI. Design of the research protocol: Prospective controlled trial including surgical patients with high risk factors for ALI (n=60) allocated to receive inhaled drugs (randomised, double-blind, cross-over mode). Main measurements: Intra-thoracic blood volume, intra- and extra-vascular lung water, hemodynamic parameters (CO, systolic arterial pressure/flow variations, dPmax, MAP, CVP), oxygenation indices (PaO2/FIO2), ventilatory parameters, clinical outcome data, histochemical and pathological data. Glossary CO = cardiac output; dPmax = maximal arterial pressure slope; SAP-V = systolic arterial pressure variations; Flow-V = Flow variations; MAP = mean arterial pressure; CVP = central venous pressure; PaO2=arterial oxygen pressure; FIO2= oxygen inspiratory fraction
