The analysis of pulmonary infect flora distribution and risk factors of stroke patients with tracheotomy in intensive care unit

Objective To investigate pulmonary infect flora distribution characteristics of stroke patients with tracheotomy in Intensive care unit (ICU) and analyze the risk factors. Methods A total of 792 cases of ICU stroke patients was selected, including 426 cases of tracheotomy patients, and 366 cases of non-tracheotomy patients. The incidence of lung infections was compared. Bacteriological examination was used for tracheotomy bacteriological studies for lung infected stroke patients with tracheotomy. Bacteria infection's characteristics was observed. The risk factors were analyzed. Results ⑴ The tracheotomy patient's lung infection rate was 23.00%, higher than 9.56% of the non-tracheotomy patients, the difference was statistically significant (χ2=19.125, P 14 d, blood glucose levels ≥7.8 mmol/L, and based diseases was significantly higher than that of patients with conscious, non-dysphagia, hospitalization time ≤14 d, blood sugar level <7.8 mmol/L, and no based diseases (P<0.05); ⑷ Consciousness, dysphagia, hospitalization, blood sugar levels, and the underlying disease were the independent risk factors of lung infection in ICU stroke tracheotomy patients (OR1=11.528, OR2=8.046, OR3=15.174, OR4=7.795, OR5=10.784, P<0.05). Conclusions Gram-negative bacteria is the main reason for pulmonary infections in ICU stroke tracheotomypatients patients with stroke. State of consciousness, invasive treatment, hospitalization, blood sugar levels, and the underlying disease are the independent risk factors.
