Abstract:
[Objective]To investigate the clinical features and high risk of very preterm infants with late-onset bacteri-al sepsis,so as to propose feasible prevention and treatment suggestions.[Methods]Totally 94 very preterm infants with late-onset bacterial sepsis from the Neonatology Department of Women's Hospital of Jiangnan University were recruited from February,2012 to January,2024.Their clinical data,including the perinatal situation,clinical symptoms,patho-gens,risk factors and treatment,were collected and analyzed.[Results]The incidence rate of very preterm infants with late-onset bacterial sepsis were 8.40 for 100 live birth babies.The major pathogens of the infections among these very pre-mature infants included gram-positive bacteria(71.1%).Logistic regression analysis showed that long term(≥7 d)use of antibiotics,invasive mechanical ventilation,indwelling central venous catheter(≥7 d),and vaginal delivery were high risk factors of very preterm infants with late-onset bacterial sepsis,the relative risk(OR)values were 2.787,4.243,3.033 and 2.174,respectively.[Conclusion]The gram-positive bacteria are the main pathogens of late-onset bacterial sepsis in very preterm infants.Long term(≥7 d)use of antibiotics,invasive mechanical ventilation,indwelling central ve-nous catheter(≥7 d)and vaginal delivery are high risk factors of very preterm infants with late-onset bacterial sepsis.The incidence of late-onset bacterial sepsis in very preterm infants can be reduced by strengthening perinatal management,shortening the time of antibiotic application and reducing invasive operations.
