ABSTRACT
Background: Umbilical vein catheter (UVC) insertion in newborns has life threatening complications like Catheter related bloodstream infections (CRBSI), Portal vein thrombosis (PVT) and other mild complications. This study has been done to assess the incidence and risk factors of complications in neonates with umbilical vein catheterisation.Methods: A prospective observational study was carried out in neonates admitted to a South Indian tertiary care hospital between January 2017- June 2018.Results: Umbilical vein catheterisation was done for 65 neonates, of them 46 completed the study. One neonate (2%) developed CRBSI and none of them developed PVT in both baseline and follow up scans. Minor complications noted were repositioning in 26%, umbilical site leak in 23%, reattempts in 19%, catheter block in 13%, periumbilical erythema in 6% and umbilical site bleed in 2%. There was no statistical significance between minor complications and baseline study characteristics.Conclusions: Although UVC is a common and easy vascular access, it is not without complications. Incidence of serious complications following umbilical vein catheterisation is low when proper technique and sterile precautions are followed. However, the occurrence of mild complications following UVC insertion is high.
ABSTRACT
Objective To explore the clinical application of located subcutaneous jugular vein inserted central catheter (LSJICC) in patients with malignant tumors. Methods The patients with malignant tumors treated in our hospital from January 2013 to December 2016 were enrolled and divided into the experimental group and the con-trol group according to the order of catheterization. Two groups were catheterized with LSJICC and PICC,respective-ly. Indwelling time of the catheter and incidence of complications were compared between two groups. The Kaplan-Meier survival curve was used to reflect the occurrence of CRBSIs in both groups,and the log-rank test was used to compare the results. The pathogenicity distribution of CRBSIs was analyzed and multivariate Cox regression analysis was performed. Results A total of 450 patients were enrolled in this study,including 228 patients in the experimental group and 222 patients in the control group. The average indwelling time of the catheter in the ex-perimental group(212.24 ± 79.80) was significantly longer than that in the control group(79.73 ± 34.86). The in-cidence of complications in the experimental group was significantly lower than that in the control group. The CRBSIs Kaplan-Meier survival curve of the experimental group was significantly better than that of the control group(P<0.01). The top three pathogens of CRBSIs were staphylococcus aureus,candida and klebsiella pneumoniae. Multivariate Cox regression analysis of CRBSIs showed that the site of catheter placement,the method of catheter placement and the type of tumor were independent risk factors for infection. Conclusion The incidence of compli-cations are significantly reduced with LSJICC,and indwelling time of the catheter is significantly prolonged,which is more in line with the actual needs of cancer patients undergoing chemotherapy.
ABSTRACT
Center vein puncture is important to the clinical infusion technology, however, its correlation infection rates rising trend year by year, especially catheter-related bloodstream infections have become one of the main reasons for primary bacteremia, seriously affected the patients survival rate, and the processing method of catheter-related bloodstream infections are intricate. The treatment and nursing of adult bloodstream infections caused by short-term central venous catheter (including peripheral central venous catheter placement) according to the provisions of the Infectious Diseases Society of America to update the catheter related infections of diagnosis and treatment guidelines are reviewed in this paper, to provide reference for management of adult short-term central venous catheter.
ABSTRACT
Objective To investigate the clinical characteristics,distribution and drug sensitivity of pathogens causing intravenous catheter-related bloodstream infections (CRBSIs) in pediatric intensive care unit (PICU) so as to use antibiotics reasonably.Methods All patients with CRBSIs in PICU of Guangdong General Hospital from September 2009 to September 2014 were investigated and the drug resistance profiles of pathogens causing CRBSIs were also analyzed retrospectively.Results Between 2009 and 2014,there were totally 10 834 catheter days and 23 episodes of CRBSIs with an incidence of 2.1 infections per 1 000 catheter days.Catheter indwell time ＜ 7 days in 9 cases (39.1％),8 to 14 days in 10 cases (43.5％),14 to 21 days in 4 cases (17.4％).There were 13 strains (56.6％) of gram-positive bacteria,5 strains (21.7％) of gram-negative bacteria and 5 strains (21.7％) of fungi.The main pathogens causing CRBSIs were coagulase negative Staphylococci (7 strains,30.4％),Staphylococcus aureus (3 strains,13.0％),Candida albicans(3 strains,13.0％),Candida parapsilosis(2 strains,8.7％),and Enterobacter cloacae (2 strains,8.7 ％).The susceptibility to Vancomycin,Linezolid and Teicoplanin of coagulase negative Staphylococ cus such as S.epidermidis and to Imipenem,Piperacillin/Tazobactam,Cefoperazone/ Sulbactam and Amikacin of gram-positive bacteria arrived at 100.0％,respectively.The candida were 100％ susceptible to Amphotericin B,5-Flucytosine,Fluconazole and Voriconazole.Twenty-one cases (91.3％) received antibiotic treatment versus no antibiotic in 2 cases (8.7％).The average number of antibiotic kinds administered on the patients with fungal infection was 4.4,bacteria were 1.4.Ten cases (43.5％) treatment with 1 kind of antibiotic,4 cases (17.4％) with 2,4 cases (17.4％) with 3,5 cases (21.7％) with more than 3.Twenty-two cases (95.7％) cured and 1 case died (4.3％).Conclusions The major species of pathogen causing CRBSIs was coagulase negative staphylococci in PICU.It is critical for clinicians to guard against fungal infection because of prolonged catheter indwelling time and more antibiotics administered before indwelling catheter.It is effective way to prevent the CRBSIs by reasonably using antibiotics and shortening the time of catheter indwelling.Monitoring CRBSIs pathogenic bacteria distribution and drug susceptibility helps reasonable administration of antibiotics in the earlier time.

ABSTRACT
INTRODUÇÃO: As infecções de corrente sanguínea relacionadas com cateter (ICSRCs) apresentam impacto significativo na morbidade e na mortalidade de pacientes internados, além de elevar custos hospitalares. A utilização de equipamentos automatizados no processamento de hemoculturas gerou uma alternativa para diagnóstico de ICSRC por meio da análise da diferença de tempo de positividade (DTP) entre hemoculturas pareadas (coletadas simultaneamente) de sangue periférico e sangue de cateter. Um diagnóstico acurado e rápido dessas infecções pode otimizar as condutas clínicas e terapêuticas, poupando a retirada precoce dos cateteres. OBJETIVOS: Avaliar na rotina a DTP como ferramenta auxiliar no diagnóstico de ICSRC e determinar os principais microrganismos isolados. MÉTODOS: Foram avaliadas retrospectivamente hemoculturas coletadas no complexo do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC/FMUSP) de maio a agosto de 2008. Somente amostras que apresentaram DTP maior que 120 minutos foram consideradas possíveis ICSRCs pelo critério laboratorial. RESULTADOS: A seção processou 11.017 hemoculturas aeróbias durante o período de estudo; somente 5% foram coletadas de forma pareada. Destas, 148 (28%) foram positivas, sendo 9% com crescimento somente em sangue periférico, 41% somente em sangue de cateter e 50% em ambas as amostras com 88% de homologia de microrganismos identificados. A DTP apresentou valores acima de 120 minutos em 50% dos casos e os microrganismos mais isolados foram Staphylococcus aureus (22%), Candida spp. (18%), Klebsiella spp. (7%) e Enterobacter spp. (7%). CONCLUSÃO: A determinação da DTP como ferramenta auxiliar no diagnóstico de ICSRC é viável e fácil de ser executada em laboratórios de rotina com automação, porém o processo de coleta das amostras pareadas deve ser rigidamente padronizado.
INTRODUCTION: Not only do catheter related bloodstream infections (CRBSIs) have considerable impact on morbidity and mortality in hospitalized patients, but they also raise hospital costs. The use of automated equipment in blood culture processing has allowed an alternative diagnosis of CRBSI by analyzing the differential time to positivity (DTP) of paired blood cultures (collected simultaneously) of peripheral blood and catheter blood. A rapid and accurate diagnosis of these infections may optimize clinical and therapeutic management, which prevents early catheter removal. OBJECTIVES: To assess DTP as an auxiliary tool for the diagnosis of CRBSI as well as to determine the main isolated microorganisms. METHODS: We evaluated blood cultures that had previously been collected in the complex Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC/FMUSP) from May to August 2008. According to the laboratory criteria, only DTP higher than 120 minutes was regarded as possible CRBSI. RESULTS: During the investigation period 11,017 aerobic blood cultures were processed, from which only 5% were paired samples. One hundred forty-eight (28%) samples were positive, from which 9% showed growth in peripheral blood, 41% only in catheter blood and 50% in both blood samples with 88% homology of identified microorganisms. DTP higher than 120 minutes occurred in 50% of the cases. The most common isolated microorganisms were: Staphylococcus aureus (22%), Candida spp. (18%), Klebsiella spp (7%). and Enterobacter spp (7%). CONCLUSION: The determination of the DTP as an auxiliary tool for the diagnosis of CRBSI is feasible and easily performed in clinical laboratories with automation, although the process of paired sample collection must be rigidly standardized.

Most nosocomial bloodstream infections among pediatric patients are related to the usage of an intravascular device.This article reviewed catheter related bloodstream infections from aspects of epidemiology,pathogenesis,diagnosis,prevention and care based on guidelines and new research both in abroad and at home.
ABSTRACT
BACKGROUND: Catheter-related bloodstream infection (CRBSI) is one of the leading types of infection, with a significant morbidity and mortality rate. We evaluated the differential time to positivity (DTP) and semi-quantitative culture of catheter segments (SQCC) as a method for diagnosing CRBSI. METHODS: From January 2010 to August 2011, 155 positive paired blood cultures which had the same organism isolated from blood cultures drawn simultaneously through the central venous catheter (CVC) and the peripheral vein were included. Positive DTP represents a DTP of least 120 min earlier for the time to detection of CVC draw than that of a peripheral vein draw. We evaluated the clinical utility of DTP and SQCC for diagnosing CRBSIs, which were further divided into two groups: confirmed (either by DTP or SQCC) and non-confirmed CRBSIs (neither DTP nor SQCC positive). RESULTS: Sixty-five percent (100/155) of episodes were confirmed to CRBSIs. In CRBSIs, Gram-positive cocci accounted for 61% of cases, non-fermenting Gram-negative bacilli represented 10%, Enterobacteriaceae for 10%, yeasts for 15%, and others for 4%. Among the confirmed CRBSI cases, 22 were both positive with DTP and SQCC, 30 cases were positive with DTP only, 12 cases were positive with SQCC only, and 36 cases which did not undergo SQCC analysis were DTP positive. The sensitivities of the DTP and SQCC techniques were 88.0% (88/100) and 53.1% (34/64), respectively. CONCLUSION: The differential time to positivity was more sensitive than the semi-quantitative culture of catheter segments for the diagnosis of CRBSIs. DTP is useful for diagnosing CRBSIs without removal of the catheter.

ABSTRACT
The peripherally inserted central catheter (PICC) provides a safe,painless,and durable intravenous pathway for the treatment of cancer patients.However,risk of intravascular catheter related bloodstream infections (CRBSI) exists during the catheter indwelling period.In this review,the definition,diagnostic criteria,characteristic of pathogens,and risk factors of CRBSI in tumor departments are analyzed and some effective prevention and nursing strategies are postulated.
ABSTRACT
BACKGROUND: Catheter-related bloodstream infections (CR-BSIs) are common, costly, and potentially lethal. The purpose of this study was to ascertain the effect of maximal sterile barrier on CR-BSIs in intensive care units. METHODS: We monitored CR-BSIs in intensive care units of Sunlin Hospital in Pohang, before (September 2005 to May 2006) and after (June to December 2006) implementation of maximal sterile barrier. CR-BSIs were identified by using the definition of Centers for Disease Control and Prevention. RESULTS: During the intervention period, the proportion of conducting maximal sterile barrier was 84%. In the pre-intervention period, 10 episodes of CR-BSIs were recorded out of a total of 1,749 catheter-days, compared to 1 episode of CR-BSI out of a total of 1,277 catheter-days in the post-intervention period. The rate of CR-BSIs was significantly reduced from 5.72 to 0.57 per 1,000 catheter-days (P=0.03). CONCLUSION: Implementation of maximal sterile barrier resulted in a significant reduction in CR-BSIs.
