美国新近的一项研究结果表明,减少机械通气的潮气量会使急性呼吸窘迫综合征(ARDS)的死亡率降低22％。 据估计美国每年大约有10～15万人患ARDS,死亡率接近50％,高于乳腺癌的死亡率。Matthary说,改变通气量可能挽救2万人的生命。尽管ARDS患者临床资料尚不肯定,但过去研究表明,过度通气会加重患者肺的损伤。 本研究选择861例急性肺损伤和ARDS患者,随机分为两组。第1组采用传统的潮气量(12ml/kg体重),第2组通
A new study from the United States shows that reducing the tidal volume of mechanical ventilation reduces the mortality rate of acute respiratory distress syndrome (ARDS) by 22%. It is estimated that in the United States, about 150,000 to 150,000 people suffer from ARDS each year, with a mortality rate of nearly 50%, higher than that of breast cancer. Matthary said changing the ventilation may save 20,000 lives. Although the clinical data of patients with ARDS are not yet confirmed, past studies have shown that hyperventilation can aggravate lung injury in patients. In this study, 861 patients with acute lung injury and ARDS were randomly divided into two groups. The first group using the traditional tidal volume (12ml / kg body weight), the first two groups
