Objective To observe the incidence of pulmonary infection in patients with traumatic cervical spinal cord injury(TCS-CI)during hospitalization,and analyze its potential risk factors.Methods The clinical data of 110 patients with TCSCI admitted to our hospital from March 2018 to March 2022 were retrospectively analyzed,and the patients were divided into infection and non infec-tion groups according to whether they had concurrent pulmonary infection during hospitalization.The potential relevant data were col-lected from two groups of patients and inter group univariate analysis and multivariate logistic regression analysis was conducted.Re-sults Of 110 cases,41(37.3%)developed pulmonary infection during hospitalization,which occurred 3 to 10 days after admission,mean 4.3 days;of these,35(85.4%)improved with active treatment,and the other 6(14.6%)eventually died due to intercurrent respiratory failure.Multivariate logistic regression model analysis confirmed that ventilator-assisted ventilation(OR =6.498,P＜0.001),serum Na+level(OR=0.693,P=0.001)and ASIA grade(OR=0.386,P＜0.001)were all independent influencing fac-tors for lung infection in TCSCI patients during hospitalization.Conclusion The incidence of lung infection in TCSCI patients during hospitalization is high,and ventilator-assisted ventilation can increase the risk of lung infection.The risk of pulmonary infection is rela-tively low in patients with high ASIA grade and normal serum Na+level.
