| Objective: To explore the application value of airway clearance technology in lung rehabilitation in coma patients with severe craniocerebral injury. Methods: A total of 68 coma patients with severe craniocerebral injury who were admitted to Intensive Care Unit (ICU) and Neurosurgical ICU of Ordos Central Hospital from March 2020 to September 2021 were selected. Patients were equally divided into observation group and control group according to the random number table. The control group was given conventional rescue treatment and nursing, and the observation group was supplemented with airway clearance technology for sputum extraction, twice a day, 30 to 40 min each time, for 14 days. Arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and oxygenation index (PaO2/FiO2) were observed before treatment, on the 3rd, 7th and 14th day after treatment in 2 groups. At 14th day, Glasgow Coma score (GCS) was recorded, diaphragm thickness score (DTF) measured by ultrasound, and proportion of patients successfully evacuated from the ventilator, transferred to a general ward and occurrence of ventilator-associated pneumonia (VAP) within 14 days were analyzed. Results: After treatment, PaO2 and PaO2/FiO2 in 2 groups continued to increase on the 3rd, 7th and 14th day compared with those before treatment, while PaCO2 continued to decrease. The PaO2 and PaO2/FiO2 in observation group increased significantly on the 3rd, 7th and 14th day as compared with those in control group, while PaCO2 decreased significantly. The differences were statistically significant (all P<0.05).The GCS score, DTF, proportion of patients successfully evacuated from the ventilator and transferred to a general ward in observation group were significantly higher than those in control group.The incidence rate of VAP was significantly lower in observation group than that incontrol group, with statistical significance (P<0.05). Conclusion: In patients with severe craniocerebral injury, airway clearance technology can effectively improve oxygen supply, diaphragmatic function, reduce the occurrence of ventilator-associated pneumonia, improve the probability of early evacuation and shorten the length of stay in the ICU, which is worthy of further clinical application. |
