Abstract:
Background: Although there are many advances in the treatment of Acute Respiratory Distress Syndrome (ARDS), the mortality rate is still high (40%-60%). The new strategy \u2018protective ventilation\u2019 helped to lower the fatality rate and shortening the duration of mechanical ventilation in comparison with traditional modes. However, there is controversy about the effects of protective ventilation. Objectives: (1) To estimate the change of arterial blood gas and hemodynamic in the first 48hrs in the patients suffering from ALI or ARDS under protective ventilation. (2) To discover the disadvantages of this ventilation mode. Subjects: 30 ALI and ARDS patients (22 males and 8 females) treated at ICU, Viet Duc Hospital between April 2005 and October 2005. Method: Prospective and self-control study. Protective ventilation was applied for these patients. Artery blood gas, hemodynamic and disadvantages of protective ventilation were monitored during first 48hrs. Results: Protective ventilation significantly lowers airway pressure (p < 0.001). There was no change of PaCO2 (p > 0.05), and PaO2 was improved clearly after 12hrs of ventilation (p < 0.05). There were no significant changes of mean arterial pressure, heart rate and central venous pressure. 83.3% patients needed a high dose of sedation during protective ventilation. Conclusion: Protective ventilation lowered airway pressure, improved PaO2 and had no hemodynamic effect. However, patients required a high dose of sedation during this mode of ventilation.
