产科合并医院感染临床特点观察

目的 探讨产科合并医院感染的特点.方法 回顾性分析2460例孕产妇的临床资料；观察医院感染发生部位、病原菌构成及相关因素.结果 2460例孕产妇发生医院感染120例占4.9％；感染部位泌尿道46例占38.3％、切口感染40例占33.3％、生殖道感染15例占12.5％、胃肠道8例占6.7％、口腔感染6例占5.0％；120例医院感染患者共培养出病原菌164株,革兰阴性杆菌82株占50.0％、革兰阳性球菌68株占41.5％、真菌12株占7.3％；医院感染因素为妊娠并发症及合并症、侵入性操作、预防性应用抗菌药物、住院时间长.结论 产科患者医院感染发生率高、感染部位多、病原菌复杂、影响因素多,应提高产科医院感染的认识,针对影响因素进行干预.

Clinical characteristics of obstetric merging hospital infections

OBJECTIVE To discuss the characteristics of nosocomial infections in obstetric department.METHODS The clinical data of 2460 pregnant women were retrospectively analyzed;the infection sites,distribution of pathogens,and related factors for infection were observed.RESULTS Nosocomial infections occurred in 120 of 2460 pregnant women,accounting for 4.9%;46(38.3%)cases were urinary tract infection,40(33.3%) cases were incision infection,15(12.5%) cases were genital tract infection,8(6.7%)cases were gastrointestinal tract infection,and 6(5.0%) cases were oral infection of the 164 strains of bacteria cultured from 120 patients with nosocomial infections included 82 strains(50.0%) of gram-negative bacilli,68 strains(41.5%) of gram-positive cocci,and 12 strains(7.3%) of fungi.Complications during the pregnancy,invasive operation,prophylactic antibiotics,and long hospital stay were the risk factors for nosocomial infections.CONCLUSION Nosocomial infections in obstetric patients are characterized by high incidence,diversity in infection sites,complex pathogens,and many impact factors.The awareness of nosocomial infections in obstetric department should be strengthened and intervention of the impact factors should be carried out.
