干预措施:

机械通气患者气道分泌物管理的常规措施:床头抬高30°~ 45°,每2小时给予患者翻身扣背、活动肢体,叩击时遵守由外向内、自下而上原则行振动排痰;每8小时给予患者口腔护理一次;使用湿热交换器,使呼吸机Y 型管温度在 34℃~ 41℃、相对湿度100%,保证病人吸入气体温湿化,评估患者有吸痰指征时,及时使用密闭式吸痰管进行吸痰,每8小时监测气囊压力,保证气囊压力维持在25~30cmH2O,按需给予雾化吸入或支气管镜吸痰保持气道通畅,严格执行手卫生。

干预措施代码:

Intervention:

Routine airway secretion management measures for mechanically ventilated patients include elevating the head of the bed by 30°–45°; repositioning the patient every 2 hours with chest percussion and limb mobilization, following the principles of percussing from the outer to the inner areas and from the lower to the upper regions to facilitate sputum clearance through vibration; performing oral care every 8 hours; using a heat and moisture exchanger to maintain the Y-piece temperature of the ventilator circuit between 34°C and 41°C and relative humidity at 100% to ensure adequate humidification of inspired gases. When suction indications are present, closed suctioning is performed promptly. Cuff pressure is monitored every 8 hours and maintained at 25–30 cmH?O. Nebulization or bronchoscopic suctioning is provided as needed to maintain airway patency. Strict hand hygiene is observed throughout all procedures.

干预措施:

在对照组的基础上给予每天三次MI-E联合密闭式吸痰治疗,连续给予5天。具体方法如下:当听诊患者肺部可闻及湿啰音;血氧饱和度下降考虑与气道分泌物相关;排除呼吸机管路抖动和积水后,呼吸机监测面板上流量和(或)压力波形仍呈锯齿样改变;考虑与气道分泌物增多相关的机械通气时潮气量减小;或容积控制机械通气时吸气峰压增大,考虑为上呼吸道分泌物或胃内容物反流到气管时。给予患者100%氧气吸入60秒,咳痰机接通电源,调节咳痰机吸气压力为呼吸机吸气压力+5cmH2O,呼气压力为吸气压力加+5cmH2O的负值;吸气、呼气时间设置为呼吸机的吸气、呼气时间+0.5s,暂停时间设置为1s,在吸气相和呼气相均使用震荡模式,震荡频率为15赫兹,振幅为5mmH2O ,给予5个周期,同时打开负压吸引器调节负压为150mmHg,使用密闭式吸痰管给予患者进行气道内浅吸痰,时间不超过15秒。吸痰过程中观察患者反应、胸腹部情况、机器运转情况、痰液引流情况等,吸痰完毕断开咳痰机,给予100%氧气吸入60秒。将密闭式吸痰管退至黑色标记线,用生理盐水冲洗吸痰管和负压管道。如果需要,可以在全天进行额外的气道吸引

Intervention:

On the basis of the control group treatment, patients in the intervention group additionally received mechanical insufflation–exsufflation (MI-E) combined with closed suctioning three times daily for five consecutive days. The specific procedure was as follows: When pulmonary auscultation revealed moist rales; when oxygen saturation decreased and was suspected to be related to airway secretions; when, after excluding ventilator circuit vibration and condensate accumulation, the flow and/or pressure waveform on the ventilator display still showed a saw-tooth pattern; when a reduction in tidal volume during mechanical ventilation was suspected to be associated with increased airway secretions; or when peak inspiratory pressure increased during volume-controlled ventilation, suggesting the presence of upper airway secretions or regurgitation of gastric contents into the trachea — MI-E therapy was initiated. Patients were pre-oxygenated with 100% oxygen for 60 seconds. The MI-E device was powered on, with the inspiratory pressure set at the ventilator’s inspiratory pressure +5 cmH?O and the expiratory pressure set at the negative of the inspiratory pressure +5 cmH?O. Inspiratory and expiratory times were adjusted to the ventilator’s inspiratory and expiratory times +0.5 s, and the pause time was set to 1 s. Oscillation mode was used in both inspiratory and expiratory phases, with a frequency of 15 Hz and an amplitude of 5 mmH?O. Each treatment consisted of five cycles. Simultaneously, a negative pressure suction unit was activated and adjusted to –150 mmHg, and airway suctioning was performed using a closed suction catheter for no longer than 15 seconds. During suctioning, the patient’s response, thoracoabdominal movements, machine performance, and sputum drainage were carefully monitored. After suctioning, the MI-E device was disconnected, and the patient was again given 100% oxygen for 60 seconds. The closed suction catheter was retracted to the black marking line, and both the suction catheter and the negative pressure tubing were flushed with normal saline. Additional airway suctioning could be performed as needed throughout the day.
