Objective: Response to acute respiratory distress syndrome (ARDS)

using the Jiawei Xuan bai Chengqi tang together with western medicine therapy

observation of Jiawei Xuanbai Chengqi tang on patients with mechanical ventilation in ARDS clinical curative effect and its mechanism of action. Method: Thirty-one patients with ARDS

were randomLy divided into the treatment group (16 cases) and control group (15 cases)

the control group received mechanical ventilation (tidal volume plus PEEP)

treatment group at the same time tube feeding on Jiawei Xuanbai Chengqi tang. Comparison of two groups of patients before treatment and after treatment of 24 hour

48 hour arterial blood gas indicators: arterial blood pH (pH)

oxygen partial pressure (PO2)

partial pressure of carbon dioxide (PCO2); ventilatory parameters: peak airway pressure (Ppeek)

platform pressure(Pplat)

positive end expiratory pressure (PEEP)、oxygen concentration (FiO2); and to compare the duration of mechanical ventilation and ICU time

ARDS causes mortality. Result: The treatment group compared with the control group

31 cases of patients before treatment of blood gas and ventilation index showed no statistically significant difference; 24 and 48 hours after treatment compared with those before treatment

48 hours were improved after treatment(P<0.05); 24 hours after treatment in two groups showed no statistically significant difference; after treatment for 24 hours and 48 hours comparison

treatment group ventilatory parameters improved indexes(P<0.05); two group of mechanical ventilation time

ICU time and mortality comparison of prognosis

treatment group better(P<0.05). Conclusion: Modified Jiawei Xuanbai Chengqi tang can effectively improve the acute respiratory distress syndrome in patients with mechanical ventilation

ventilation blood gas index. Decrease the duration of mechanical ventilation and retain ICU time

to strengthen the protection of patients with mechanical ventilation in ARDS

improve the patients prognosis.
