Filter by:Patients affected by acute lung injury-acute respiratory distress syndrome (ALI-ARDS) undergo a positron emission tomography (PET) scan in order to analyse lung function.
The purpose of this study is to determine whether N-acetylcysteine given intravenously 1 day pre-operatively is effective in preventing inflammation in the lungs, as measured by tests on blood, breath and lung specimens, in patients undergoing surgery to remove a portion of lung.
The purpose of this study is to test a treatment that tries to reduce the amount of fluid in the lungs of subjects with acute lung injury to see if this is helpful.
Acute lung injury (ALI)/Acute Respiratory Distress Syndrome (ARDS) is a severe lung condition that causes respiratory failure. This study will examine if differences in genes and biomarkers involved in the inflammation and blood clotting process may affect the severity of and recovery from ALI/ARDS in children hospitalized with the condition.
The investigators aim is to study the specific lung elastance in ALI/ARDS patients during invasive mechanical ventilation, in supine and prone position.
The hypothesis of this study is use of CytoSorb hemoperfusion device as an adjunctive therapy to the standard of care in treating ARDS/ALI patients in the setting of sepsis will result in improved clearance of cytokines when compared to control patients receiving only the standard of care.
We propose that as low tidal volume ventilation has proven to be beneficial in patients with established ARDS it may have a role in preventing the onset of acute lung injury in the cardiac surgical population. Institution of low tidal volume ventilation in the operating room may reduce the release of the cytokines and interleukins that have been known to contribute to the development of acute lung injury. In this study, we propose that the institution of low tidal volume ventilation in the operating room will reduce the incidence of acute lung injury. Measurement of PaO2 to FiO2 ratio twenty four and forty eight hours post operatively will help determine if there is a difference in oxygenation between the two groups. Chest X-ray findings, time to extubation and length of ICU stay will also determine if there is a role for low tidal volume ventilation in the operating room. We will also attempt to establish a causative mechanism by measuring plasma levels of cytokines known to be associated with the development of ARDS.
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.
Background : 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 : 1. 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 2. 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
Current American-European Consensus Conference (AECC) definitions for ALI and ARDS are inadequate for inclusion into clinical trials due to the lack of standardization for measuring the oxygenation defect. We questioned whether an early assessment of oxygenation on specific ventilator settings would identify patients with established ARDS (persisting over 24h).
