医院神经外科手术后患者医院感染及干预研究

目的了解神经外科术后患者医院感染情况及病原菌特点,提出干预措施。方法通过医院网络信息系统实施前瞻性监测,分2个阶段对某医院664例神经外科住院患者医院感染率和致病菌进行了调查。结果第一个阶段2010年6-8月调查手术后患者332例,发生手术后感染33例、36例次,感染率9.94%、例次感染率10.84%。第二阶段在实施干预措施后(2010年9-11月)调查术后患者332例,发生术后感染15例,感染率为4.52%。感染部位以中枢神经系统感染居首位。从第一阶段36次感染患者标本中共检出致病菌39株,革兰阴性杆菌占64.10%,革兰阳性球菌占25.64%,其余为真菌。结论该医院神经外科住院患者术后感染率较高,采取干预措施后感染率明显下降,据此制定出有效干预措施。

STUDIES ON NOSOCOMIAL INFECTION OF NEUROSURGICAL PATIENTS AFTER OPERATION AND INTERVENTION

Objective To know the nosocomial infection of neurological surgery postoperative and pathogens characteristics,and to propose the interventions.Methods Prospective surveillance by hospital information network systems was used to investigate 664 cases of neurological surgery and inpatient hospital infection pathogens by two phases.Results The first phase was from June to August 2010.There were 332 cases of post-operative investigated,the occurrence of infection was 33 cases and 36 case-times after surgery,and the infection rate was 9.94%,case-time infection rate was 10.84%.The second phase was the implementation of intervention measures(September-November 2010).332 cases of postoperative patients were investigated,15 cases had postoperative infection,the infection rate was 4.52%.The most infection site was the central nervous system.From the first phase of 36 specimens,39 strains of pathogens were detected out.Of which Gram-negative bacilli accounted for 64.10%,Gram-positive cocci accounted for 25.64%,the rest was fungi.Conclusion The hospital inpatient neurosurgical postoperative infection rates was high.And infection rates decreased significantly after intervention.We should develop effective interventions according to this.
