ObjectiveTo
investigate and analyze the risk factors of intrauterine infectious pneumonia
in preterm infants, and to explore its etiological distribution.MethodsFrom
January 2019 to August 2021, 60 premature infants with intrauterine infectious
pneumonia and 60 healthy premature infants in our hospital were selected as
research objects, which were set as observation group and control group.The
data of preterm infants and their mothers in the observation group and the
control group were compared, the risk factors of infectious pneumonia during
intrauterine period in preterm infants were analyzed. The throat swab samples
of premature infants with intrauterine infectious pneumonia were collected for
bacterial culture, and the distribution of pathogenic bacteria of premature
infants with intrauterine infectious pneumonia was counted.ResultsUnivariate
analysis showed that between the observation group and the control group, there was
statistical difference in amniotic fluid pollution,fetal distress,
chorioamnionitis, maternal C reactive protein, late pregnancy fever,
gestational hypertension and gestational diabetes mellitus (P<0.05); there
were no statistically significant differences in maternal age, previous fertility,
gestational age or fetal gender between the two groups(P>0.05). Multivariate
Logistics regression analysis showed that amniotic fluid pollution,
intrauterine distress, chorioamnionitis, maternal C-reactive protein ≥8.0 mg/L, fever in the third trimester, hypertension during pregnancy
and gestational diabetes mellitus were the risk factors leading to intrauterine
infectious pneumonia in premature infants(P<0.05). Among 60 cases of
premature infants with intrauterine infectious pneumonia, 85 strains were
isolated by pathogen culture, including 59 strains of gram-negative bacteria, 20 strains of gram-positive bacteria and 6 strains of fungi.ConclusionThe occurrence of
intrauterine infectious pneumonia in premature infants is mainly related to
amniotic fluid pollution, intrauterine distress, chorioamnionitis, maternal C-reactive protein, fever in the third trimester, hypertension during
pregnancy,and gestational diabetes mellitus. Targeted preventive measures
should be taken according to the risk factors, and prevention and treatment
strategies should be formulated according to the distribution types of
pathogenic bacteria of intrauterine infectious pneumonia in premature infants.
