Acute respiratory distress syndrome (ARDS) develops in patients with predisposing conditions that induce systemic inflammatory response such as sepsis, pneumonia, acute pancreatitis, major trauma, or multiple transfusions. Sepsis is the most common cause of ARDS. Sepsis-related ARDS patients have significantly lower PaO2 /FiO2 ratios than patients with non-sepsis-related ARDS. Furthermore, their recovery from lung injury is prolonged, weaning from mechanical ventilation less successful, and extubation rate slower. Clinical outcomes in patients with sepsis-related ARDS are also worse, associated with significantly higher 28-day and 60-day mortality rates (31.1% vs. 16.3% and 38.2% vs. 22.6%, respectively). It is extremely important to optimally adjust ventilator setting to current condition of lungs, while providing all other therapeutic measures in the treatment of sepsis, severe sepsis and septic shock. The pool of data on treatment possibilities for patients with ARDS grows every year, with specifically designed mechanical ventilation strategies. Ventilator modes and adequate positive end-expiratory pressure (PEEP) settings play a major role in these strategies. However, how can we best apply these experimental and clinical data to everyday clinical practice? This article emphasizes protective ventilation as a measure that is proven to reduce mortality in this group of patients, when systematically and consistently applied.
急性呼吸窘迫综合征(ARDS)发生于患有易引发全身炎症反应的基础疾病的患者,如脓毒症、肺炎、急性胰腺炎、重大创伤或多次输血。脓毒症是ARDS最常见的病因。与脓毒症无关的ARDS患者相比,脓毒症相关的ARDS患者的动脉血氧分压/吸入氧分数值(PaO2 /FiO2)显著更低。此外,他们从肺损伤中恢复的时间延长,机械通气脱机成功率更低,拔管率更慢。脓毒症相关的ARDS患者的临床结局也更差,28天和60天死亡率显著更高(分别为31.1%对16.3%和38.2%对22.6%)。在治疗脓毒症、严重脓毒症和脓毒性休克时,根据肺部当前状况优化调整呼吸机设置,同时提供所有其他治疗措施极为重要。关于ARDS患者治疗可能性的数据每年都在增加,有专门设计的机械通气策略。呼吸机模式和适当的呼气末正压(PEEP)设置在这些策略中起主要作用。然而,我们如何才能最好地将这些实验和临床数据应用于日常临床实践呢?本文强调,当系统且持续地应用保护性通气时,它是一种经证实可降低这类患者死亡率的措施。
