Pathogens Characteristics And Risk Factors Of Nosocomial Infection In Neonatal Intensive Cure Unit

Objective: to study the newborn common pathogens of nosocomial infectiondistribution and risk factors, and to provide a theoretical basis for clinical treatment.Methods: NICU3726newborns in our hospital statistics, establish a control groupLogistic regression analysis risk factors. Results:(1) infection status: our nosocomialinfection of the newborn was7.7%, and respiratory infection rate was80.4/1000correlation machine mechanical ventilation-day, gestational age, birth weight andbreathing machine correlation infection rates was not statistically significant.(2) infectedplace: lung, oral cavity, blood line infections total infection cases times respectively56.7%,8.1%and11.3%. Skin mucous membrane infection and urinary tract infection, a certainpercentage.(3) hospital infection pathogenic bacteria distribution for: G+bacteriaaccounted for37.6%separation strains; G-bacteria strains of the separation of60.3%.(4)risk factors: birth weight or1500g, gestational age than32weeks, less than gestationalage, neonatal asphyxia, parenteral nutrition, mechanical ventilation for hospital infectionassociated risk factors (P＜0.001); Including parenteral nutrition, birth weight than1500g,mechanical ventilation for the main risk factors (OR:8.135,3.142, and2.377).Conclusion:(1) our newborn low nosocomial infections, mainly for lung infection.(2)newborn with nosocomial infection of gram-negative bacteria is given priority to,common bacteria for pneumonia clay "bacteria and e. coli. Gram-positive bacterialinfection with streptococcus viridans and staphylococcus aureus see more.(3) birth weightthan1500g, less than gestational age, was born with choking history, gestational age than32weeks, parenteral nutrition, mechanical ventilation for hospital infection associated riskfactors. Birth weight than1500g, parenteral nutrition, mechanical ventilation to ourhospital infection NICU major risk factors.(4) prevention measures: strict hand hygiene,master mechanical ventilation indications, executive sterile operation, reasonable arrangement of cleaning respiratory frequency and avoid the repeated intubation, shortenthe time of mechanical ventilation, strengthen early trace feed, etc can have the function ofthe hospital infection prevention.
