研究目的:

通过比较经鼻咽通气道高流量吸氧和传统鼻导管吸氧两组间无痛支气管镜诊疗中低氧血症及其他不良事件的发生率,探究肥胖患者行支气管镜诊疗期间更安全有效的氧疗方法。  

Objectives of Study:

By comparing the incidence rates of hypoxemia and other adverse events during sedated bronchoscopy diagnosis and treatment between the two groups of patients receiving high-flow oxygen through nasalpharyngeal airway and those receiving traditional nasal catheter oxygen therapy, we aim to explore a safer and more effective oxygen therapy method for obese patients during bronchoscopy diagnosis and treatment.

Traditional nasal cannula oxygen therapy group(C group)

Sample size:

干预措施:

经鼻导管吸氧,氧流量设定为2L/min,必要时提高到6L/min

干预措施代码:

Intervention:

Oxygen is administered through a nasal cannula at a flow rate of 2 l/min, If necessary, the flow rate can be increased to 6 l/min.

组别:

经鼻咽通气道高流量吸氧组(H组)

样本量:

123

Group:

High flow oxygenation via nasopharyngeal airway group(H group)

Sample size:

干预措施:

将高流量双腔鼻塞导管其中一个软腔用胶带封闭,另一个软腔连接鼻咽通气道,在支气管镜引导下在一侧鼻孔插入润滑良好的鼻咽通气道,镜下见鼻咽通气道前端到达声门上位置后用胶带固定其位置,随后连接高流量吸氧装置,FiO2设定为100%,湿度设定为37℃,氧流量设定为30-50L/min

干预措施代码:

Intervention:

Close one of the soft cavities of the high-flow dual-chamber nasal catheter with tape, and connect the other soft cavity to the nasopharyngeal airway. Under bronchoscopy guidance, insert the lubricated nasopharyngeal airway into one nostril. Under the microscope, observe that when the front end of the nasopharyngeal airway reaches the position above the vocal cords, fix its position with tape. Then connect the high-flow oxygen supply device. Set the FiO2 to 100%, the humidity to 37℃, and the oxygen flow rate to 30-50L/min.

盲法:

在建立外周静脉通路后,每个患者都被给予一个常规的鼻导管吸氧,经鼻咽通气道高流量吸氧组在患者入睡后插入鼻咽通气道并与高流量吸氧设备连接,从而使患者盲入分组。所有的病人都在每个中心的同一个房间里接受治疗,HFNC设备总是放在他们的床边。

Blinding:

After peripheral intravenous access was established, each patient was given a regular nasal cannula ,The high flow oxygen inhalation group with nasopharyngeal airway inserted and connected to the high flow oxygen supply device after the patient fell asleep,thereby blinding patients to the group assignment. The patients all had the procedure in the same room in each centre, and the HFNC oxygenation device was always at their bedside.
