研究目的:

1、研究开放式与密闭式吸痰对非高PEEP机械通气ARDS患者呼吸及循环的影响。 2、分析下呼吸道感染患者定植和致病菌病原学和临床特点。  

Objectives of Study:

1. To study the effects of open and closed suctioning on the respiration and circulation of non-high PEEP mechanically ventilated ARDS patients. 2. To analyze the pathogenic and clinical characteristics of colonizing and pathogenic bacteria in patients with lower respiratory tract infections.

Description for medicine or protocol of treatment in detail:

 

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=5 cmH?O, 100 mmHg=5 cmH?O, PaO?/FiO?<=100 mmHg (5)Lower respiratory tract infection: The diagnosis of lower respiratory tract infection is based on the "Guidelines for the Diagnosis and Treatment of Hospital-Acquired Pneumonia and Ventilator-Associated Pneumonia in Chinese Adults (2018 Edition)" and the Diagnostic Criteria for Hospital Infections (Trial) by the Ministry of Health of the People's Republic of China (2001) 1)Criteria for identifying pathogenic bacteria: Positive sputum culture and meeting three of the following conditions: a. The diagnosis of lower respiratory tract infection is clear b. Treatment is effective based on the results of antibiotic susceptibility testing c. Positive observation of immunopathological phenomena in sputum d. The concentration of bacteria isolated in sputum culture is>10^7cfu/ml 2)Criteria for identifying colonizing bacteria: Positive sputum culture and meeting three of the following conditions: a. The diagnosis of lower respiratory tract infection is not sufficient b. The diagnosis of lower respiratory tract infection is clear but treatment is ineffective based on the results of antibiotic susceptibility testing c. Negative observation of immunopathological phenomena in sputum d. The concentration of bacteria isolated in sputum culture is between 10^3cfu/ml and 10^7cfu/ml 2.PEEP level: 5<=PEEP<10cmH?O 3.18 years<=age<=85 years and the patient has signed the informed consent form.

排除标准:

1、PEEP≥10cmH2O或PEEP<5cmH2O 2、年龄<18岁或>85岁 3、孕妇、植入心脏起搏器者、胸部外伤或皮损限制胸带放置者、气胸及处于终末期患者

Exclusion criteria:

1.PEEP>=10cmH?O or PEEP<5cmH?O 2.Age<18 years or>85 years 3.Pregnant women, patients with implanted cardiac pacemakers, patients with chest trauma or skin lesions that restrict the placement of chest straps, patients with pneumothorax and patients in the terminal stage.
