目的:探讨急性呼吸窘迫综合征(ARDS)机械通气肺复张效果。方法:将2014年1月-2016年1月收治的60例ARDS患者随机分为对照组(n=30)与观察组(n=30),对照组采取机械通气,观察组采取机械通气加肺复张,比较两组动脉血气分析指标、呼吸力学参数、肺复张成功率、并发症发生率。结果:肺复张后30 min、24 h、48 h时间点,观察组Pa O_2、Pa O_2/Fi O_2高于对照组(P<0.05);肺复张后30 min、1 h、4 h时间点,观察组Cst、Pplatecm H_2O、PIP与对照组有明显差异(P<0.05)。观察组肺复张成功率明显高于对照组,而并发症发生率明显低于对照组(P均<0.05)。结论:对ARDS患者采取机械通气肺复张的肺复张成功率明显提高。
Objective: To investigate the effect of mechanical ventilation on pulmonary reexpansion in patients with acute respiratory distress syndrome (ARDS). Methods: Sixty patients with ARDS who were admitted from January 2014 to January 2016 were randomly divided into control group (n = 30) and observation group (n = 30). The control group was given mechanical ventilation. The observation group was given mechanical ventilation plus lung Reexplained, compared arterial blood gas analysis index, respiration mechanics parameters, success rate of pulmonary reclamation, complication rate. Results: Pa O 2 and Pa O 2 / Fi O 2 in the observation group were significantly higher than those in the control group at 30 min, 24 h and 48 h after lung recruitment (P <0.05) The observation group Cst, Pplatecm H_2O, PIP significant difference with the control group (P <0.05). The success rate of pulmonary recanalization in the observation group was significantly higher than that of the control group, while the incidence of complications was significantly lower than that of the control group (all P <0.05). Conclusion: The success rate of pulmonary recanalization in ARDS patients with mechanical ventilation and pulmonary recanalization was significantly improved.
