本组病例全部符合1982年成人型呼吸窘迫综合征诊断和分级标准(试行草案)。其中男性10例,女性7例。年龄在15～63岁。17例中死亡8例,病死率为47.06%。原发病有病毒性肺炎、消化道出血伴失血性休克、多发性骨折及高血压脑病各1例,颅脑损伤伴多发性骨折13例。起病特点除1例病毒性肺炎缓慢起病外,其余病例均有突然发作性呼吸困难,且呈进行性加重,一般吸氧效果欠佳。颅脑损伤病人发病时间,多在伤后或手术后4小时～4天,平均24小时。呼吸频率在30～40次/分。难以纠正的进行性低氧血症是本组病例的突出临床表现,PaO_2下降是本病的重要诊断指标。本组大部分病例虽经吸入较高浓度氧,但PaO_2升高不明显,有些病人反而呈进行性下降,但尽管如此,适当氧疗,尤其吸入40%浓度的氧
This group of patients all meet the 1982 adult respiratory distress syndrome diagnosis and grading standards (draft). Including 10 males and 7 females. Aged 15 to 63 years old. Among the 17 cases, 8 died and the case fatality rate was 47.06%. The primary disease was viral pneumonia, gastrointestinal bleeding with hemorrhagic shock, multiple fractures and hypertensive encephalopathy in 1 case, brain injury associated with multiple fractures in 13 cases. In addition to the onset of a slow onset of viral pneumonia, the rest of the cases have sudden onset of dyspnea, and was progressive increase, the general effect of poor oxygen. Patients with craniocerebral injury onset time, mostly in injury or after surgery 4 hours to 4 days, an average of 24 hours. Respiratory rate at 30 to 40 beats / min. Intractable progressive hypoxemia is the outstanding clinical manifestations of this group of patients, PaO 2 decline is an important diagnostic indicator of the disease. Although the majority of cases in this group inhaled higher concentrations of oxygen, PaO 2 increased not obvious, but some patients showed a progressive decline, but in spite of appropriate oxygen therapy, especially inhaled 40% concentration of oxygen
