目的

探讨颅脑损伤颅内感染后并发肺部感染患者的病原学特征分布及其相关危险因素。

方法

收集2016年11月至2019年10月本院收治的89例颅脑损伤颅内感染后并发肺部感染患者为研究对象(观察组),另收集同期颅脑损伤颅内感染后未发生肺部感染患者40例为对照组。分析颅脑损伤颅内感染后并发肺部感染患者的病原菌特征分布情况,分别采用单因素及多因素Logistic回归分析法分析影响颅脑损伤颅内感染患者并发肺部感染的危险因素。

结果

89例颅内感染患者共检出病原菌120株,其中革兰阳性菌71株(59.17%,71/120),以金黄色葡萄球菌32株(26.67%,32/120)、表皮葡萄球菌23株(19.16%,23/120)为主;革兰阴性菌43株(35.83%,43/120),以大肠埃希菌19株(15.83%,19/120)、铜绿假单胞菌16株(13.33%,16/120)为主;89例肺部感染患者中共检出病原菌112株,其中革兰阳性菌34株(30.36%,34/112),以金黄色葡萄球菌22株(19.64%,22/112)为主;革兰阴性菌78株(69.64%,78/112),以鲍曼不动杆菌36株(32.14%,36/112)为主。单因素分析显示,年龄、开放性损伤、多发损伤、气管切开、合并症、休克、住院时间、有吸烟史与颅脑损伤颅内感染患者并发肺部感染有关(P<0.05);多因素分析显示,年龄>50岁、多发损伤、气管切开、合并症>2个、休克及住院时间>15 d为影响颅脑损伤颅内感染患者并发肺部感染的独立危险因素。

结论

颅脑损伤颅内感染后并发肺部感染患者以革兰阴性菌感染为主,多种因素可增加颅脑损伤颅内感染患者并发肺部感染的风险,临床应采取相应针对性预防及治疗措施,降低患者肺部感染概率,改善预后。

Objective

To investigate the pathogenic characteristics and risk factors of pulmonary infection in patients with craniocerebral injury.

Methods

The clinical data of 89 patients with pulmonary infection after craniocerebral injury admitted to our hospital from November 2016 to October 2019 were included as study subjects (observation group), and 40 patients without pulmonary infection after craniocerebral injury in the same period were collected as a control group. The distribution of pathogenic bacteria in patients with pulmonary infection after craniocerebral injury was analyzed, and single-factor and multi-factor Logistic regression analyses were used to identify the risk factors of pulmonary infection in patients with craniocerebral injury.

Results

A total of 120 strains of pathogenic bacteria were detected in 89 patients with intracranial infection, of which 71 (59.17%) were Gram-positive, including 32 (26.67%) strains of Staphylococcus aureus and 23 (19.16%) strains of Staphylococcus epidermidis; 43 (35.83%) were Gram-negative, including 19 (15.83%) strains of Escherichia coli and 16 (13.33%) strains of Pseudomonas aeruginosa. A total of 112 strains of pathogenic bacteria were detected in 89 patients with pulmonary infection, of which 34 (30.36%) were Gram-positive, including 22 (19.64%) strains of Staphylococcus aureus; 78 (69.64%) were Gram-negative bacteria, including 36 (32.14%) strains of Acinetobacter baumannii. Single-factor analysis showed that age, open injury, multiple injury, tracheotomy, complications, shock, length of stay, and smoking history differed significantly between the two groups (P<0.05). Age>50 years, multiple injury, tracheotomy, number of complications>2, shock, and hospital stay>15 days were identified to be the independent risk factors for pulmonary infection in patients with intracranial infection (P<0.05).

Conclusion

Gram-negative bacterial infection is the main cause of pulmonary infection in patients with intracranial infection after craniocerebral injury. Many factors are associated with the risk of pulmonary infection in patients with intracranial infection after craniocerebral injury. Therefore, we should take corresponding preventive and therapeutic measures to reduce the probability of pulmonary infection and improve the prognosis.
