纳入标准: |
1、根据柏林定义诊断明确的ARDS机械通气患者,符合以下诊断标准: (1)起病时间:从已知临床损害,以及新发或加重呼吸系统症状至符合诊断标准时间,≤7天 (2)胸部影像学:双侧浸润影,不能用积液、大叶/肺不张或结节来完全解释 (3)肺水肿原因:呼吸衰竭不能用心力衰竭或液体过度负荷来完全解释;如无相关危险因素,需行客观检查(如超声心动图)以排除静水压增高型肺水肿 (4)氧合情况: 轻度:PEEP或CPAP≥5 cmH2O时,200 mmHg<PaO2/FiO2≤300 mmHg 中度:PEEP≥5 cmH2O时,100 mmHg<PaO2/FiO2≤200 mmHg 重度:PEEP≥5 cmH2O时,PaO2/FiO2≤100 mmHg (5)下呼吸道感染: 下呼吸道感染诊断采用《中国成人医院获得性肺炎与呼吸机相关性肺炎诊断和治疗指南(2018年版)》中华人民共和国卫生部医院感染诊断标准(试行)(2001) A致病菌的判定标准:痰培养阳性且符合下列条件中的3条: a.下呼吸道感染诊断明确 b.依据药敏结果用药后治疗有效 c.痰液免疫病理现象观察阳性 d.痰培养时分离出的细菌浓度>107cfu/ml B定植菌的判定标准:痰培养阳性且符合下列条件中的3条: a.下呼吸道感染诊断依据不足 b.下呼吸道感染诊断明确但依据药敏结果用药后治疗无效 c.痰液免疫病理现象观察阴性 d.痰培养时分离出的细菌浓度在103cfu/ml~107cfu/ml之间 2、PEEP水平:5≤PEEP<10cmH2O 3、18岁≤年龄≤85岁且患者签署知情同意书 |

|
Inclusion criteria |
1.ARDS patients diagnosed according to the Berlin Definition, who meet the following diagnostic criteria:
(1)Onset time: Time from known clinical injury and new or worsening respiratory symptoms to meeting the diagnostic criteria, <=7 days
(2)Chest imaging: Bilateral infiltrates that cannot be fully explained by effusion, lobar/atelectasis or nodules
(3)Cause of pulmonary edema: Respiratory failure that cannot be fully explained by cardiac failure or fluid overload; if there are no related risk factors, objective tests (such as echocardiography) should be performed to exclude hydrostatic pulmonary edema
(4)Oxygenation status:
Mild: When PEEP or CPAP>=5 cmH?O,2 00 mmHg |
||||||||||||||||||||||
|
排除标准: |
