Abstract: OBJECTIVE To explore the related risk factors and prevention countermeasures of patients with cerebral hemorrhage complicated with pulmonary infection, so as to provide references for clinical treatment. METHODS Clinical data of 100 cases of patient with cerebral hemorrhage complicated with pulmonary infection (pulmonary infection group) and 100 cases of patient with cerebral hemorrhage without pulmonary infection (uninfected group) were randomly selected, and the risk factors of pulmonary infection were analyzed. RESULTS The constituent ratios of smoking history, history of chronic obstructive pulmonary disease, history of diabetes mellitus, history of chronic bronchitis, hypoalbuminemia, ventricular hemorrhage, use of breathing machine, nasal feeding, sputum suction, continuous intracranial pressure, pseudo bulbar palsy, prophylactic use of antibiotics, and use of corticosteroids of pulmonary infection group were 46.00%, 10.00%, 24.00%, 14.00%, 8.00%, 44.00%, 25.00%, 28.00%, 67.00%, 32.00%, 26.00%, 46.00%, and 26.00%, respectively, which were high than those of uninfected group of 34.00%, 2.00%, 12.00%, 3.00%, 1.00%, 24.00%, 11.00%, 15.00%, 53.00%, 18.00%, 13.00%, 25.00%, and 11.00%. The age and NIHSS score of pulmonary infection group were (65.87±6.85) years old and (18.69±6.54) points, which were higher than those of uninfected group of (60.09±4.22) years old and (8.95±5.88) points, the GCS score of pulmonary infection group was (11.03±3.82) points, which was lower than that of uninfected group of (13.92±2.57) points (P<0.05). CONCLUSION There are many risk factors for pulmonary infection in patients with cerebral hemorrhage, and interventions should be made according to related factors during the treatment to reduce the incidence of pulmonary infection.
