心律失常患者医院感染的临床特点及影响因素研究

Study on Clinical Characteristics and Influencing Factors of Arrhythmia Patients with Nosocomial Infection

目的探讨心律失常患者医院感染的临床特点及影响因素。方法回顾性分析唐山市第八医院2010年1月-2011年12月收治的124例心律失常患者的临床资料,统计医院感染发生率,对患者的感染特点及影响因素进行分析。结果本组心律失常患者的医院感染发生率为16.1%(20/124),以呼吸道感染最常见,G+菌感染7例,占35.0%;G-菌感染11例,占55.0%;经过药敏试验发现病原菌对万古霉素、亚胺培南、阿米卡星、头孢哌酮/舒巴坦、头孢他啶、环丙沙星等敏感性较高。医院感染的发生受到患者年龄、有器质性心脏病以及有创性治疗的影响(P<0.05)。结论临床医师应该了解并掌握患者医院感染的临床特点及影响因素,为患者医院感染的防治工作提供参考依据。

Objective To explore the clinical characteristics of arrhythrnia patients with nosocomial infection, and study its influencing factors. Methods The clinical data of 124 arrhythmia patients hospitalized in the Eighth Hospital of Tangshan from January 2010 to December 2011 were retrospectively analyzed. The incidence of nosocomial infection was counted, the in- fection characteristics and influencing factors of the patients were analyzed. Results The nosocomial infection rate of the ar- rhythrnia patients was 16.1% （20/124）, and respiratory tract infection was the commonest. There were 7 patients with G＋ bac- terial infection and 11 patients with G- bacterial infection, accounting for 35.0% and 55.0%, respectively. The susceptibility testing found that pathogens were highly sensitive to vancomycin, imipenem, amikacin, cefoperazone/sulbactam, ceftazidime, and ciprofloxacin. The occurrence of nosocomial infection was affected by the patient＇s age, structural heart disease and invasive treatment （P 〈 O. 05）. Conclusions Clinicians should understand and master the clinical characteristics and influencing fac- tors of nosocomial infection of arrhythmia patients so as to provide the reference for prevention and cure of nosocomial infection in arrhythrnia patients.
