RESUMEN
Objective To explore the incidence of nosocomial infection in a neonatal intensive care unit(NICU) so as to come out with scientific and effective measures for infection control. Method Real-time monitoring system was used for investigating nosocomial infection of ventilator-associated pneumonia (VAP), catheter-associated urinary tract infection (CAUTI), and central-line associated bloodstream infection (CLABSI) in NICU. Results Among 2 836 patients, 28 patients were infected, with the rate of 0.99%and the case-time infection rate of 1.09%. The nosocomial infection manifested to be blood infection with the rate of 35.48%, and 10%of main pathogens were gram-negative bacteria. Conclusions Targeted monitoring in NICU can make the nosocomial infection information acquired timely, objectively and accurately. The strict and intensified prevention and control program should be adopted to reduce the neonatal nosocomial infection.
RESUMEN
Objective To study the constituent ratio and antimicrobial susceptibility patterns of pathogenic bacteria in patients with urinary tract infection (UTI) in NICU. Methods Data were collected retrospectively of neonates who admitted to NICU in St. Louis Children' s Hospital in Washington University School of Medicine between Jan 1 ,2005 and Dec 31,2006. Results The prevalence of UTI in NICU was 6. 5%. Gram-negative organisms were the most common agents of UTI in NICU,of which Ecoli ranked highest ,followed by Klebiella and Enterobacter cloacae. Of gram-positive organisms Enterococcus species and Coagulase-negative Staphylococci were the most common agents. Cefepime and gentamycin showed high activity against gram-negative organisms. Overall, non-E. coli microorganisms showed more resistances compared with Escherichia coli. The best susceptible antibiotics for gram-positive organisms were vancomycin and rifampin. Almost all gram-negative bacteria showed resistant to ampicillin and all of gram-positive bacteria resistant to penicillin and oxacillin. Conclusion Gram-negative organisms were the most common agents of UTI in NICU in this study. The drug resistance of bacteria is severe,especially to ampicillin and penicillin,which will be no longer the first choice clinically. So urine culture should be examined when initiating antibiotics treatment for UTI.
RESUMEN
PURPOSE: The score for neonatal acute physiology (SNAP) based on physiologic derangements, is applied to variable fields including morbidity as well as mortality estimate. We evaluate the clinical usefulness of SNAP and SNAP variants for neonatal acute severity and mortality. METHODS: Twenty-one neonates were evaluated the SNAP, SNAP-PE, SNAP-II, and SNAPPE-II, who survived more than 24 hours in Neonatal Intensive Care Unit in Department of Pediatrics, Kyunghee University from July 2003 to December 2004. A study group included 21 neonates as death group and a control group matched for gestational age and birth weight. We analyzed the differences of clinical usefulness of SNAP and SNAP variants indices between the two groups. RESULTS: 1) SNAP:The scores were ranged 2-18 (median 6.5) in survival group and 9-31 (median 13.0) in death group. 2) SNAP-PE:The scores were ranged 2-48 (median 16.5) in survival group and 23-75 (median 32.0) in death group. 3) SNAP-II:The scores were ranged 0-16 (median 10.5) in survival group and 10-62 (median 21.0) in death group. 4) SNAPPE-II:The scores were ranged 0-45 (median 24.5) in survival group and 35-109 (median 44.0) in death group. The median values were higher in those who were died:SNAP<0.05 (P-value), SNAP-PE<0.01, SNAP-II<0.01, SNAPPE-II<0.01 showing the significant differences. CONCLUSION: The study shows that SNAP and SNAP variables are useful for the evaluation of acute severity and excellent predictors of neonatal survival. They would help the management of neonatal intensive care unit.
