Abstract: Infections transmitted from the NICU have increased mortality, prolonged hospital stay and increased neonatal hospital costs; These infections have increased in recent decades due to the increased survival of low birth weight infants. In this study, by determining the incidence of nosocomial blood infection and identifying some risk factors, more appropriate methods of treatment and prevention can be adopted.
This is a descriptive-analytical study. All neonates who were hospitalized in NICU of Bandar Abbas Children's Hospital in 1399 for at least 4 days were studied. At the time of admission, blood cultures were usually performed. Blood necropsies were also performed on infants who developed sepsis symptoms at least 48 hours after admission. If the first positive blood culture of the infant was at least 48 hours after hospitalization or another bacterium grew in subsequent blood cultures, it was known as a nosocomial blood infection. Then their antibiotic susceptibility was measured and demographic characteristics and risk factors for nosocomial blood infection including sex, weight, gestational age, type of delivery, comorbidity and antibiotic susceptibility through data collection form, completion and results through descriptive statistics (frequency). And percentages) were presented and the obtained values were compared by chi-square test.
In this study, the incidence of nosocomial blood infection was 9.98% (38 out of 388 neonates) (CI: 5.5- 11.25%). The incidence of infection in very low birth weight neonates was significantly higher than other neonates. But no significant relationship was found between other risk factors (sex, gestational age, type of delivery and associated disease) with the incidence of infection. Also, 30 cases (63.3%) of Enterobacter, 10 cases (73.3%) of Klebsiella, 6 cases (10%) of Citrobacter and 1 case (1.34%) of Staphylococcus aureus were identified from 30 infants with nosocomial bloodstream infections. According to the antibiogram, all neonates with nosocomial hematopoietic infection with gram-negative bacteria (29 cases) were resistant to common antibiotics (NICU, gentamicin, amikamis, and zoxime stiffness).
by identifying the causative bacteria, which is different from other studies, and the resistance of these bacteria to common antibiotics, a more appropriate way to prevent, control and treat nosocomial blood infections is presented.
