研究目的:

比较高PEEP法及间断声门下吸引法在清除机械通气的ARDS患者囊上滞留物的效果。  

Objectives of Study:

To comparison the effect of high PEEP method versus intermittent subglottic suction method on the elimination of subglottic secretions on artificial airway endotracheal tube cuff and the outcomes of ARDS patients.

药物成份或治疗方案详述:

干预组患者入科第一天起,每4小时进行一次高PEEP法清除囊上滞留物。操作步骤为:暂停肠内营养,吸净人工气道内及口鼻腔分泌物。将患者置于平卧位。将PEEP增加至10cmH2O,如果患者原有呼吸机PEEP设置>10 cmH2O,则使用原有PEEP值。将注射器连于气管导管气囊,观察呼吸机波形,当呼吸机波形显示吸气末时,抽空气囊,可听到气流从口腔中冲出的声音,立即将气囊充气,并吸引口咽部分泌物。上述操作可反复进行,直至口咽部无分泌物吸出为止。操作完毕后抬高床头、恢复体位及呼吸机设置,测量并维持气囊压于25-30cmH2O。 

Description for medicine or protocol of treatment in detail:

Patients in the intervention group undergo high PEEP method every 4 hours from the day of admission to the department, in order to eliminate subglottic secretions. The operational procedure is as follows: Firstly, suspend enteral nutrition and suction the secretions in the artificial airway, oral cavity, and nasal cavity. Then place the patient in the prone position and increase PEEP to 10 cmH2O. If the patient's original ventilator PEEP setting is > 10 cmH2O, use the original PEEP value. Connect the syringe to the tracheal tube airbag and observe the ventilator waveform. When the ventilator waveform indicates the end of inspiration, evacuate the airbag, listen for airflow rushing out of the mouth; then immediately inflate the airbag and remove oropharyngeal secretions. The aforementioned procedure can be repeated until no secretion is extracted from the oropharynx. Following the procedure, it is important to elevate the head of the bed, readjust the position and ventilator settings, and monitor and maintain the airbag pressure at 25-30 cmH2O.  

纳入标准:

①年龄>18岁,符合基于Berlin定义的ARDS医疗诊断的患者;②通气方式为机械通气,且留置的人工气道可进行声门下吸引。

Inclusion criteria

① patients aged >18 years who met the medical diagnosis of ARDS based on the Berlin definition; ② ventilation mode was mechanical ventilation and the retained artificial airway was available for subglottic suction.

排除标准:

Exclusion criteria:

① patients with undrained pneumothorax; ② patients with interstitial pneumonia; ③ patients with extremely unstable hemodynamics, such as systolic blood pressure lower than 90 mmHg; ④ those who have already had VAP and have not yet recovered when admitted to the ICU.
