About this trial

600 comatose patients admitted to the hospital in China from June 2024 to June 2028 were randomly divided into groups A and B. Group A used intermittent negative pressure suction through oral and pharyngeal ventilation, while group B used continuous negative pressure suction through regular oral and nasal suction.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

1. Clinical diagnosis of stroke; 2. Clinical diagnosis of comatose;

Disqualifiers

1. Clinical diagnosis of multiple organ failure; 2. Clinical diagnosis of multiple organ bleeding;

Trial design

Design model

Crossover

Treatments tested in this trial

  • continuous negative pressure suction

    Procedure/Surgery

    (1) Open the mouth with a tongue depressor; (2) Apply paraffin oil to the front end of the sputum suction tube; (3) Insert a suction tube into the mouth to aspirate phlegm.

  • Intermittent negative pressure sputum suction through oral pharyngeal airway

    Procedure/Surgery

    (1) Insert the oropharyngeal airway parallel into the oral cavity; (2) Apply paraffin oil to the front end of the sputum suction tube; (3) The suction tube is inserted into the deep oral cavity through the middle lumen of the oropharyngeal airway; (4) Intermittent negative pressure for suction and suction of sputum

Trial outcomes

Primary outcomes

1

Blood oxygen saturation before and after sputum aspiration

The degree of binding between oxygen and hemoglobin (Hb) in arterial blood

Time frame
Not exceeding 1 day
2

Suctioning time

All time required for sputum suction process

Time frame
Not exceeding 2 minute
3

Degree of airway bleeding

Use a disposable sputum collection device to aspirate sputum for patients and differentiate the blood content under a blue LED light.

Time frame
Not exceeding 30 minute

Secondary outcomes

1

Patient family satisfaction

After suctioning, use a satisfaction questionnaire to survey the operating nurses, with a minimum score of 1 and a maximum score of 5. The higher the value, the higher the satisfaction.

Time frame
Not exceeding 1 day
