不同俯卧位通气时间对中重度肺内/外源性ARDS患者的治疗效果.

Objective: To investigate the effect of different ventilation time in the prone position on patients with endogenous/exogenous ARDS. Methods: 30 endogenous/30 exogenous ARDS patients were randomly devided into 4 groups, ventilation in the prone position for 2 h and 4 h. Recording the score of APCHEII, oxygenation index, the absorption situation in X-ray, HR, MAP, extubation time, the time out of ICU.Results: The APCHEII scores HR and MAP in four groups have no significant statistics (P＞0.05); 4h ventilation for endogenous ARDS patients has a better indicators than 2 h in oxygenation index, the absorption situation in X-ray, extubation time and the time out of ICU (P＜0.05); 2 h and 4 h ventilation for exogenous ARDS patients can improve indicators above, two groups have no significant statistics (P＞0.05), the results of exogenous groups are precede than endogenous group (P＜0.05). Conclusion: Ventilation in the prone position can improve the situation of ARDS patients, both endogenous patients and exogenous patients. Exogenous ARDS patients have a better treatment effect after the ventilation of 2h, however, endogenous patients need longer time and have a non-ideal prognosis. [ABSTRACT FROM AUTHOR]
