新生儿脐部细菌定植及感染因素的分析

Newborn Navel Region Bacterium Field Planting and Infection Factor Analysis

目的研究新生儿脐部细菌定植及感染的情况，为制定控制新生儿感染措施提供理论依据。方法对每位新生儿生后第三天脐部进行病原学监测，了解脐部定植茵及感染茵的情况，并对其感染12项相关因素进行分析。结果346例新生儿脐部有细菌定植327例，定植率为94．5l％，脐部感染39例，感染率11．27％。主要为大肠埃希氏茵、金黄色葡萄球菌、其它肠道杆茵及耐药茵等。脐带残端长度、脐带直径、脐带脱落时问、脐带贴卫生、手卫生对脐部感染有影响（P〈0．05）。结论采取必要的措施。减少细菌定植，抑制致病病原体生长，避免发生新生儿脐部感染。

Objective To study the bacterial colonization and infection of newborn umbilical situation, neonatal infection control measures for th~ development of theoretical basis. Methods On the third day after birth, each newborn navel region was treated for pathogen monitoring, understanding of umbilical colonization and infection of bacteria strains, and its infection - related factors were analyzed 12. Results 327 cases were bacterial colonization, the colonization rate was 94.51 % 39 eases were incisional infection, and the infection rate 11.27%, The infection bacillis were Eseherichia eoli, Staphylococcus anreus, other intestinal bacilli and drug resistance monocytogenes. Was the position of the um- billeal tied, the navel remnant end length, the umbilical cord diameter, the umbilical cord pastes the health, and the hand health, have effects on the umbilical infection（ P 〈 0.05 ）. Conclusion Some essential measurement should be taken to, reduce the bacterium field planting, inhibit the growth of disease pathogens, aim avoid having the newborn navel region infection.
