目前,ARDS患者的死亡率居高不下,探索有效的治疗手段特别重要。呼气末正压(PEEP)是治疗ARDS的常用手段。与传统通气方式相比,使用PEEP,特别是高水平PEEP对ARDS的疗效及患者死亡率的影响尚不清楚。作者通过回顾性研究,探讨高PEEP对多病因的严重ARDS患者死亡率的影响。 34个月期间收住外科ICU的严重ARDS患者,PEEP大于15cmH_2O者纳入观察组。严重ARDS诊断标准:存在明显诱因,吸入氧浓度(FiO_2)>50%时,PaO_2<70mmHg,X线胸片显示斑片状阴影,肺顺应性
Currently, there is a high mortality rate among ARDS patients and it is particularly important to explore effective treatments. Positive end expiratory pressure (PEEP) is a common treatment for ARDS. The effect of using PEEP, especially high levels of PEEP, on ARDS and patient mortality compared with traditional ventilation is not clear. The authors through a retrospective study to explore the impact of high PEEP on the incidence of multiple ARDS patients with mortality. Patients with severe ARDS who underwent surgical ICU for 34 months had PEEP greater than 15 cm H 2 O in the observation group. Severe ARDS diagnostic criteria: There is a clear incentive, PaO2 <70mmHg when FiO2> 50%, X-ray chest shows patchy shadows, lung compliance
