新生儿脐部细菌定植及感染干预措施的研究

RESEARCH ON NEWBORN UMBILICAL BACTERIAL FIELD PLANTING AND INFECTION INTERVENTION

目的研究新生儿脐部感染的干预措施，观察其干预效果。方法采用细菌分离鉴定技术，对新生儿脐带断带部位细菌定植情况进行检测，并对防感染干预措施的效果进行评估。结果新生儿脐带断带部位采用在常规干预措施的基础上，用一种季铵盐喷剂加强护理，可有效降低新生儿脐带部位感染率。本研究设定的对照组、单独碘伏护理组和季铵盐强化护理组在观察病例数相同的条件下，新生儿脐带部位感染率依次为11．27％、4．05％和0．87％。但3组新生儿脐带在断带后3—5d内，其分泌物细菌检出率均达90％以上。结论本研究采用一种以季铵盐为主要杀菌成分的喷剂作为强化护理干预措施，可有效降低新生儿脐带部位感染率，值得推广使用。

Objective To study the intervention measure for neonatal umbilical infection and the observe the intervention effects. Methods Bacterium separation and identification technology were used to detect bacterial disinfection of neonatal navel strip breakage, and evaluate effect interventions. Results Based on the routine intervention of newborn umbilical, a kind of quaternary ammonium salt was used for strengthen nursing, which could decrease the disinfection rate. The disin- fection rates of control group, iodophors nursing group and quaternary ammonium salt strengthen nursing group were 11.27%, 4. 05% and 0. 87% respectively. But the bacterial detection rates the three groups were all above 90% after stripe breakage for 3 - 5days. Conclusion This intervention measures used a quaternary ammonium salt as the main anti- septic spray as strengthening nursing. It can effectively reduce the neonatal umbilical cord site infection rate, which is worth promoting.
