Summary

Acute 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.

Detailed description

In patients with acute respiratory distress syndrome (ARDS), protective lung strategy and positive end expiratory pressure (PEEP) therapy should be started as early as possible to avoid lung damage by high pressures, volumes and fraction of inspired oxygen (FiO2). Recruitment is a strategy aiming at re-expanding the collapsed lung tissue and then maintaining an adequate level of PEEP to prevent subsequent de-recruitment. The objective of this study was to compare safety and efficacy of two lung recruitment maneuvers (RM): stepwise PEEP elevation with determination of the alveolar collapsing pressure versus sustained lung inflation in ARDS patients

Conditions

• Acute Respiratory Distress Syndrome

Interventions

Type	Name	Description
PROCEDURE	Recruitment maneuver	group I: Recruitment by CPAP 30 cm/H2o for 30 seconds group II: Using pressure controlled ventilation with end-inspiratory minus end-expiratory pressure of 15 cmH2O, respiratory rate of 10-15 C / min. PEEP was increased by 5 cm/ H2O every 2 minutes till Maximum of 40 cmH2O, patient was considered recruited if PaO2 of 250 mmHg was achieved. Then progressive decreases of PEEP in steps of 2 cmH2O every 2 minutes till PaO2 dropped by a 10% or more (alveolar collapsing pressure)
PROCEDURE	recruitment maneuver	recruitment as done by CPAP 30 cm/ H2o for 30 seconds or by stepwise elevation of PEEP by 5 cm/ H20 till 40 Cm/ H2o
