2014年度新生儿感染流行病学调查研究

Epidemiological investigation on infections of newborn in 2014

目的对医院2014年度新生儿感染进行流行病学调查,探讨新生儿感染的预防重点及防治措施。方法选取医院2014年1-12月住院感染新生儿共890例,对所有新生儿的临床资料进行统计分析,对引发新生儿感染的相关因素进行研究。结果新生儿感染以呼吸系统居首位,占54.27%,血液系统、神经系统感染次之,分别占34.38%、26.74%,其余感染较低;胎龄〈30周的感染新生儿显著多于〉30周的新生儿,差异有统计学意义（P〈0.05）;而胎龄30~37周的感染新生儿多于〉37周的新生儿,差异有统计学意义（P〈0.05）;体质量〈1 000g的感染新生儿显著多于〉1 000g的新生儿,差异有统计学意义（P〈0.05）;1 000~1 500g感染新生儿多于〉1 500g的新生儿,差异有统计学意义（P〈0.05）;不同性别新生儿的感染率差异无统计学意义。结论医院应重视新生儿感染,对胎龄较小、体质量较轻的新生儿应加强感染的防范,以控制、降低新生儿感染的发生。

OBJECTIVE To investigate the newborn infections in the hospital in 2014 so as to discuss the major preventive measures.METHODS A total of 890 cases of infected newborns hospitalized from Jan.to Dec.2014 were selected.The clinical data of all infected newborns were statistically analyzed to find out the related factors.RESULTS Respiratory system was the main susceptible parts for newborns and the infection rate was up to54.27%,followed by blood system and nervous system,accounting for 34.38% and 26.74%.The neonates with infections with the gestational age less than 30 weeks were more than the neonates with infections with the gestational age more than 30 weeks,with significant difference（P〈0.05）.However,the neonates with infections with the gestational age varying from 30 to 37weeks were more than the neonates with the gestational age more than 37 weeks,with significant difference（P〈0.05）.The neonates with infections with the body weight less than 1 000 g were more than the neonates with the body weight more than 1 000 g,with significant difference（P〈0.05）.The neonates with infections with body weight varying from 1 000 to 1 500 g were more than the neonates with the body weight more than 1 500 g,with significant difference（P〈0.05）.There was no significant difference in the infection rate between different genders of neonates.CONCLUSIONThe hospital should pay attention to the newborn infection,especially strengthen prevention to those under gestational age and light newborns so that the infections can be controlled and decreased.
