Abstract:
Objective To study the clinical manifestations, risk factors, treatment and prognosis of carbapenem-resistant klebsiella pneumoniae (CRKP) sepsis in premature infants. Method A retrospective analysis was done for the premature infants diagnosed with klebsiella pneumoniae sepsis and admitted to the neonatal wards of the Hospital from April 2015 to March 2018. According to the results of drug sensitive test, the infants was assigned to CRKP group and non-CRKP group. The perinatal factors, clinical manifestations, treatment, and prognosis of the two groups were analyzed. Furthermore, high risk factors for CRKP group were analyzed. Result A total of 39 premature infants with KP sepsis were included in our study. There were 23 cases in the CRKP group and 16 cases in the non-CPAP group. In CPKP group, the gestational age was (29.5 ± 0.6) weeks, the birth weight was (1177 ± 272) g. In non-CRKP group, the gestational age was (30.0 ± 0.5) weeks, the birth weight was (1387 ± 220) g. Univariate Logistic regression analysis showed that low birth weight was a risk factor for CRKP sepsis in premature infants (OR=1.203, 95％CI 1.068～1.355, P=0.002). The proportion of that required combination treatment with antibiotics and the incidence of intracranial hemorrhage after infection in the CPKP group were both higher than that in the non-CRKP group (P<0.05). The proportion and duration of antibiotics used in the first week before the onset of infection in infants with CRKP sepsis and combined antibiotic treatment were significantly higher than those in infants with CPKP sepsis and single antibiotic treatment. The use of antibiotics in the first week before the onset of infection was an independent risk factor for the combined drug treatment of premature infants with CRKP sepsis (OR=10.500, 95％CI 1.015～108.577, P=0.049). In the CRKP group, the improvement rate was 87.0％(20/23), 2 cases were withdrew, and 1 case deceased. In the non-CPKP group, the improvement rate was 87.5％(14/16), and 2 deceased. Conclusion The lower the birth weight, the greater the risk of infection with CRKP sepsis. The proportion of need combination treatment with antibiotics is high in infants with CRKP sepsis. The use of antibiotics in the first week before the onset of infection is a risk factor for combined antibiotic treatment in premature infants with CRKP sepsis .
