Purpose of the study is to reduce the number of deaths in the ICU due to Acute Respiratory Distress Syndrome (ARDS)

The Teaching and Research Institute Heart Hospital (IEP / HCor) in São Paulo (SP), heads the largest study in intensive care to reduce the number of deaths from acute respiratory distress syndrome (ARDS), a major cause deaths of ICU patients. The study is being conducted in 120 intensive care units in Brazil, Colombia, Mexico and Italy. Other countries, like Spain, Chile, Argentina and Uruguay have already shown interest in participating in the study, which will involve about two thousand patients.

ARDS is a type of pulmonary insufficiency caused by various disorders that cause fluid buildup in the lungs (pulmonary edema), requiring the use of artificial respirators. Without prompt treatment, severe deprivation of oxygen caused by the syndrome causes death in 90% of patients.

"The ventilation is necessary to save the life of the patient and produces trauma to the lungs, as air enters under positive pressure, causing distention of the alveoli," says the medical coordinator of research activities, Dr. Alexandre Biasi.

"With the technique that is used today only 50% of patients survive. With the new technique being tested, the hospital has no additional cost because it uses the same devices, and can achieve a more positive outcome, with the potential to reverse several cases, "says responsible for the IEP / HCor, medical Otavio Berwanger.

Currently the procedure for mechanical ventilation in ARDS patients following ARDS Net protocol that is followed worldwide for 10 years. The study is testing new techniques of standardization for the use of mechanical ventilation, in order to increase the chances of patient survival.

According to the authors, the technique called cellular recruitment involves high pressure air for a few minutes in order to open collapsed alveoli. This technique is added to the former, ie, while preventing the distension of the lung can open collapsed alveoli.

The final results of the study will be published in 2015 and if they are positive, the technique evaluated in the Brazilian study will default, reducing the number of deaths in intensive care units of public and private hospitals, all over the world.
