目的:探讨下呼吸道感染老年患者病原菌检测、耐药性及预后的影响因素。方法:对635例下呼吸道感染住院老年患者的临床资料进行回顾性探讨。结果:共分离病原菌225株,下呼吸道感染老年患者常见病原菌主要是革兰阴性(G-)杆菌139株,其次是G+球菌57株、真菌(念珠菌)29株;常见病原菌耐药性较高;经临床住院综合治疗,采取有效的预防和护理措施,235例治疗后痊愈,364例病情有所好转,30例治疗无效,6例治疗后最终死亡;预后主要影响因素是重视并加强临床护理及心脑血管病、糖尿病、多脏器功能衰竭等。结论:由于下呼吸道感染老年患者常见病原菌耐药性较高,应合理用药;有效的预防和护理措施及心脑血管病、糖尿病、多脏器功能衰竭等是影响其预后主要因素,临床应积极防治并加强护理,改善预后。
Objective: To investigate the influencing factors of pathogens detection, drug resistance and prognosis in elderly patients with lower respiratory tract infection. Methods: The clinical data of 635 hospitalized elderly patients with lower respiratory tract infection were retrospectively reviewed. Results: A total of 225 pathogens were isolated. The common pathogens of elderly patients with lower respiratory tract infection were 139 Gram-negative bacilli, 57 strains of G + cocci and 29 of fungi (Candida). The common pathogenic bacteria were more resistant ; After clinical hospital comprehensive treatment, take effective preventive and nursing measures, 235 cases recovered after treatment, 364 cases have improved, 30 cases were ineffective, 6 cases eventually died after treatment; The main prognostic factor is to pay attention to and strengthen the clinical nursing And cardiovascular disease, diabetes, multiple organ failure and so on. Conclusion: As the lower respiratory tract infection in elderly patients with higher resistance to pathogens should be reasonable medication; effective prevention and care measures and cardiovascular and cerebrovascular disease, diabetes, multiple organ failure is the main factor affecting their prognosis, the clinical should be positive Prevent and strengthen care, improve prognosis.
