新生儿出生体重与NICU医院感染相关性研究

目的研究新生儿出生体重与新生儿重症监护病房(NICU)医院感染的关系,为有效防控提供依据。方法采用回顾性和前瞻性相结合调查方式,对2007-2008年度与2009-2010年度该医院NICU所有出院新生儿分段进行调查。结果该医院NICU在4年内,共监测4 811例出院新生儿,发生医院感染101例、106例次,新生儿医院感染率为2.10%、例次感染率为2.20%。新生儿出生体重≤1 000 g,日感染发生率为5.43‰;出生体重≥2 500g,日感染发生率为1.65‰。结论新生儿出生体重越低,医院感染发生率越高,低出生体重儿是医院感染的高危人群。

STUDY ON RELATIONSHIP BETWEEN NEONATAL BIRTH WEIGHT AND NOSOCOMIAL INFECTION IN NICU

Objective To study the relationship between neonatal birth weight and nosocomial infection in neonatal intensive care unit(NICU),and provide basis for the effective prevention.Methods Retrospective and prospective methods were used to survey all the infants discharged from NICU in the hospital in 2007 to 2008 and 2009 to 2010.Results Of the 4 811 infants discharged from NICU during the four years,101 infants suffered from nosocomial infection on 106 cases,with the nosocomial infection rate of 2.10% and the infection case-rate of 2.20%.When the neonate's birth weight was less than 1 000 g,the daily infection rate of them was 5.43%.And the daily infection rate of neonate with birth weight more than 2500g was 1.65%.Conclusion The lower birth weight of neonate,the higher incidence of nosocomial infection.Low birth weight infants are population with high-risk of nosocomial infection.
