NCT06508008

Brief Summary

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.

Study Arms (2)

Intermittent negative pressure sputum suction through oral pharyngeal airway

EXPERIMENTAL

(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

Procedure: continuous negative pressure suctionProcedure: Intermittent negative pressure sputum suction through oral pharyngeal airway

continuous negative pressure suction

NO INTERVENTION

(1) Use a tongue depressor to open the mouth; (2) Lubricating the front end of the sputum suction tube with paraffin oil; (3) Insert a suction tube into the oral cavity to aspirate phlegm.

Interventions

(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.
