[Respiratory support using multi-level lung ventilation in patients in critical state with systemic inflammatory
Purpose:
To prove the effectiveness of the method and improve lung gas exchange in patients with non-homogenous lung tissue damage with multi-level (3-level, MLV) ventilation.
Materials And Methods:
Artificial lung ventilation (ALV) with MLV carried out in 13 patients with severe lung tissue damage (polytrauma, pneumonia and ARDS) treated at the unit of resuscitation and intensive care (for septic patients) SCH No 1 of Omsk since May 2011. The initial values of pO2 and oxygenation index were significantly reduced, the fraction of the intrapulmonary shunting - essentially increased. During the first day after the beginning of respiratory support with the use of MLV, was registered pO2, SaO2 and oxygenation index growth, there was a positive x-ray dynamics of improved lung tissue biomechanics. As a result of the ALV with MLV in 11 patients had achieved steady improvements of arterial oxygenation. The use of respiratory support with MLV in patients with severe lung damage leads to a significant improvement of the alveolar ventilation and arterial oxygenation, and to reduce the intrapulmonary shunting level. The use of this type of ventilation system versus traditional methods of respiratory therapy leads to respiratory failure solution, in reduce of duration of ALV terms and stay in the intensive care unit.
