Effect of different endotracheal suctioning methods on clearance of airway secretions in patients with craniocerebral injury and tracheotomy (不同吸痰方式对颅脑损伤气管切开患者气道分泌物清除的效果观察)

Objective To investigate the effect of endotracheal suctioning method using suctioning sputum with suctioning salivary tube in patients with craniocerebral injury undergoing tracheotomy. Methods A randomized controlled trial was conducted in 106 patients with traumatic brain injury after tracheotomy who met the inclusion criteria. According to the random number table method, they were divided into two groups, with 53 cases in each group. The experimental group was treated with endotracheal suctioning method using sputum suction tube combined with sputum suction tube, while the control group was treated with routine sputum suction method using sputum suction tube . The secretion severity grade under electronic laryngoscope swallowing function assessment (FEES) before and after sputum aspiration was compared between the two groups. The number of sputum aspiration, blood oxygen saturation and heart rate changes at 1 minute before and after sputum aspiration were observed in the two groups at 1, 3 and 7 days after admission. The mucosal damage under electronic hose bronchoscopy was observed in the two groups at 1, 3 and 7 days after admission. Results The severity of FEES was significantly lower in the experimental group than in the control group (P
