Taurolidina para prevenir infecciones asociadas a catéter venoso central en niños con insuficiencia intestinal: experiencia preliminar en un hospital terciario chileno / Taurolidine for the prevention of catheter-related infections in children with intestinal insufficiency: preliminary experience in a Chilean tertiary hospital

INTRODUCCIÓN: Taurolidina es una molécula con propiedades anti-endotóxicas, antimicrobianas y anti-inflamatorias, que inhibe la adhesión bacteriana, lo que ha permitido usarla como terapia de sellado en catéter venoso central de larga duración (CVC) para prevenir infecciones del torrente sanguíneo asociadas a CVC (ITS-CVC). OBJETIVO: Dar a conocer una experiencia preliminar, la primera en Chile, con taurolidina como terapia de sellado para prevenir ITS-CVC y reportar su eficacia. MÉTODO: Se instiló una solución en base a taurolidina en el CVC de tres niños con insuficiencia intestinal, dependientes de alimentación parenteral, atendidos en un hospital terciario de la Región de Valparaíso, y se comparó la tasa de ITS-CVC antes y después de su uso mediante un análisis retrospectivo. RESULTADOS: en los dos pacientes que iniciaron terapia de sellado inmediatamente después de instalado el CVC, la tasa de ITS-CVC se logró llevar a cero, mientras que, en el tercero, portador de un CVC instalado 9 meses antes, con ITS-CVC recurrentes, un nuevo episodio de ITS-CVC obligó a suspender la profilaxis. CONCLUSIONES: La terapia de sellado con solución en base a taurolidina previno las ITS-CVC cuando ésta se inició al momento de instalarse el CVC, no así en un CVC antiguo con ITS-CVC recurrentes.

BACKGROUND: Taurolidine is a molecule with anti-endotoxic, anti-microbial and anti-inflammatory properties that inhibits bacterial adhesion, allowing for its use as lock therapy for the prevention of catheter-related bloodstream infections (CRBSI) in long-term central venous catheters (CVC). AIM: To report a preliminary experience, the first one in Chile, using lock therapy with taurolidine for the prevention of CRBSI and to report its efficacy. METHOD: A taurolidine-based solution was instilled in the CVC of three children with intestinal insufficiency dependent on parenteral nutrition, attended in a Chilean tertiary hospital, and the rate of CRBSI before and after its use was compared in retrospect. RESULTS: In the two patients who started lock therapy immediately after the installation of their CVC, the rate of CRBSI was brought to zero, whereas in the third patient, who had a 9 months-old CVC with a recurrent CRBSI history, an intercurrent CRBSI forced discontinuation of the prophylaxis. CONCLUSIONS: Lock therapy with a taurolidine-based solution prevented CRBSIs when it was begun immediately after installing the CVC, in contrast with an old CVC with a history of recurrent CRBSIs.

O uso da lock terapia na prevenção e tratamento de infecção relacionada ao cateter venoso central de longa permanência: revisão integrativa / Using lock therapy to prevent and treat long-term central venous catheter-related infections: an integrative review

Introdução: A lock terapia, ou terapia de bloqueio, consiste na administração e manutenção de uma solução, em concentração supra terapêutica, nos cateteres venosos centrais. Estas soluções combinam antimicrobianos altamente concentrados com um anticoagulante, sendo aplicáveis tanto para a prevenção, quanto para o tratamento da infecção relacionada ao cateter. Objetivo: Sintetizar o conhecimento sobre o uso da lock terapia na prevenção e tratamento de infecção relacionada ao cateter intravascular de inserção central. Método: Revisão integrativa da literatura, sendo a busca realizada nas seguintes bases de dados CINAHL, Cochrane Central, Embase, LILACS, PubMed, Scopus e Web of Science, abrangendo o período de 1 janeiro de 2010 a 3 de março de 2020, sem restrições de idioma. As referências foram exportadas para o gerenciador EndNote e para o Rayyan, para a seleção dos estudos. As etapas de amostragem, categorização dos estudos, avaliação dos estudos incluídos, interpretação dos resultados e síntese do conhecimento foram realizadas por dois revisores de forma independente. Em seguida, foi realizada uma busca manual nas referências dos estudos incluídos. Os dados foram analisados de forma descritiva. Resultados: A amostra compilou 15 estudos. Seis estudos (40%) abordaram o uso da lock terapia como prevenção de infecção relacionada ao cateter venoso central, e nove artigos (60%) abordaram tal terapia como tratamento. Os artigos incluídos nessa revisão que abordaram a prevenção relatam o uso de soluções antimicrobianas não antibióticas (taurolidina (n=2), etanol (n=2), citrato trissódico (n=1) e nitroglicerina (n=1)). Dentre os nove estudos que abordaram a lock terapia como tratamento para a infecção, a maioria (n=7) utilizou soluções antibióticas, (dois estudos avaliaram a eficácia da daptomicina e os outros cinco utilizaram soluções antibióticas variadas). Os outros dois estudos utilizaram soluções antimicrobianas (ácido clorídrico e taurolidina) associadas com antibioticoterapia sistêmica. Dentre os 15 estudos, em apenas um não foi possível especificar a duração da intervenção. Dois avaliaram a eficácia da lock terapia em curta duração (de três a quatro dias) e seis avaliaram em maior duração (entre 10 e 14 dias). Cada estudo especificou uma técnica de intervenção e o tempo de permanência da solução intraluminal. Em relação ao risco de viés, foram avaliados cinco ensaios clínicos randomizados pela ferramenta da Cochrane Risk of Bias (RoB 2), sendo todos de baixo risco. Dois ensaios clínicos sem randomização avaliados pela ferramenta proposta pelo Joanna Briggs Institute (JBI) resultaram em risco de viés baixo. Dentre os oito estudos observacionais, a ferramenta AXIS avaliou sete como sendo de baixo risco e um como risco moderado. Conclusões: Na prevenção identificou-se o uso de antimicrobianos não antibióticos como o etanol. A taurolidina também foi utilizada em um estudo relacionado ao tratamento, em associação com antibioticoterapia sistêmica. Em três estudos sintetizados para as situações de tratamento da infecção relacionada ao cateter, o antibiótico utilizado foi a daptomicina endovenosa. Tais antibióticos sistêmicos, utilizados concomitantemente na maioria dos estudos de tratamento, foram selecionados em conformidade com o resultado da hemocultura e antibiograma

Introduction: Lock therapy, or blockade therapy, is the administration and maintenance of a solution, at a dosage higher than the therapeutic one, in central venous catheters. Blockade solutions combine highly concentrated antimicrobials with an anticoagulant. They can be applied to both prevent and treat catheter-related infections. Objective: To summarize the knowledge about use of lock therapy to prevent and treat intravascular catheter-related infections. Methods: Integrative literature review, whose search was carried out in the databases CINAHL, Cochrane Central, Embase, LILACS, PubMed, Scopus and Web of Science, considering the period from January 1, 2010 to March 3, 2020, without any languages restriction. The references were exported to EndNote and subsequently to Rayyan, so studies could be selected. Sampling, study categorization, study evaluation, interpretation of results, and synthesis of knowledge were executed by two researchers independently and blindly. A manual search was then carried out in the references of the included articles. The data were analyzed descriptively. Results: The final sample was composed of 15 studies. Six studies (40%) addressed the use of lock therapy to prevent central venous catheter-related infections and nine publications (60%) addressed this therapy as a form of treatment. The articles included in this review that addressed prevention reported use of nonantibiotic antimicrobial solutions (taurolidine (n=2), ethanol (n=2), trisodium citrate (n=1), and nitroglycerin (n=1)). Among the nine studies that evaluated lock therapy as a treatment alternative, most (n=7) described the use of antibiotic solutions (two evaluated the effects of daptomycin and five reported the application of varied antibiotic solutions). The other two articles described use of antimicrobial solutions (hydrochloric acid and taurolidine) associated with systemic antibiotic therapy. Among all 15 studies, one did not specify the intervention duration, two assessed the efficacy of lock therapy in the short term (from three to four days), and six assessed it within a longer duration (between 10 and 14 days). Each study specified an intervention technique and length of permanence of the intraluminal solution. Regarding risk of bias, five randomized clinical trials were evaluated with the tool Cochrane Risk of Bias (RoB 2), which indicated all as low risk of bias. Two nonrandomized clinical trials were assessed through the tool proposed by the Joanna Briggs Institute, and resulted in low risk of bias. Among all eight observational studies, the AXIS tool evaluated seven as showing low risk of bias and one as moderate risk of bias. Conclusions: Regarding prevention, the studies reported the use of non-antibiotic antimicrobials such as ethanol. The taurolidine was also mentioned in a study describing therapeutic applications, in combination with systemic antibiotic therapy. In three studies addressing treatment of catheterrelated infections, the antibiotic used were Daptomycin. These systemic antibiotics, which were concomitantly used in most treatment studies, were chosen according to the results of blood culture with antibiogram

Candidemia: características en los adultos mayores / Candidemia: characteristics in elderly patients

Resumen Introducción: La candidemia es una micosis sistémica asociada a los cuidados de la salud de elevada morbimortalidad. Los adultos mayores presentan las tasas más altas y la información en esta población es escasa. Objetivos: Describir las características de las candidemias en los adultos mayores, identificar factores asociados a mortalidad y evaluar la utilidad de un score predictor. Métodos: Estudio retrospectivo de las candidemias en adultos mayores en un hospital de la ciudad de Buenos Aires. Se analizaron todos los episodios en pacientes mayores de 60 años en un período de ocho años. Resultados: Se incluyeron 59 episodios. La co-morbilidad más frecuente fue diabetes mellitus. El principal sitio de origen fue infección asociada a catéter (45%). Sólo 17% presentó un Candida score mayor a 2,5. La mortalidad global a las 48 h fue 20% y a 15 días 49%. Las variables asociadas a mortalidad fueron: shock, asistencia respiratoria mecánica (ARM), plaquetopenia, insuficiencia renal y leucocitosis (rango p < 0,0001-0,006). En el análisis multivariado el shock fue la única variable independiente asociada a mortalidad (HR 4,02 [IC 95% 1,18-13,72], p = 0,026). Conclusiones: La mitad de los adultos mayores con candidemia falleció en los primeros 15 días. Shock, ARM, plaquetopenia, insuficiencia renal y leucocitosis fueron factores asociados a mortalidad. El score predictor de uso habitual no fue útil en esta población.

Abstract Background: Candidemia is a nosocomial bloodstream infection and an important cause of comorbidity and mortality. Elderly patients present the highest rates of candidemia but data about this population is scarce. Aims: To describe characteristics of candidemia in elderly patients, to identify risk factors associated with mortality and to evaluate the usefulness of a predictive score. Methods: A retrospective observational study of candidemia in elderly patients from a tertiary care hospital was carried out. We analyzed all Candida bloodstream infections during an eight-year period in patients older than 60 years. Results: Fifty-nine episodes were included. Diabetes was the most frequent comorbidity. Most candidemia were catheter related infections (45%). Only 17% of patients had a Candida score > 2.5. Overall mortality at 48 hours was 20%, and at 15 days was 49%. Mortality-related factors were shock, assisted mechanical ventilation, thrombocytopenia, renal failure and leukocytosis (p range < 0.0001-0.006). On multivariate analysis septic shock was independently associated with mortality (HR 4.02 [CI 95% 1.18-13.72] p = 0.026). Conclusions: Nearly half of patients with candidemia died during the first fifteen days. Shock, assisted mechanical ventilation, thrombocytopenia, renal failure, and leukocytosis were factors associated with mortality. The predictive score was not useful in this population.

Bacteriemia por Stenotrophomonas maltophilia en niños: análisis de 10 años / Stenotrophomonas maltophilia bacteremia in children - A 10-year analysis

Stenotrophomonas maltophilia es un microorganismo gramnegativo, multirresistente. La información sobre la bacteriemia por S. maltophilia en niños es limitada. Se revisaron los datos de 10 años de un hospital de niños de alta complejidad. Se incluyó a niños de 0 a 18 años con hemocultivos o cultivos del catéter positivos. Se identificaron 20 cepas de S. maltophilia en 12 niños con infección confirmada, cuya mediana de edad fue 28 meses (intervalo: 3,1-187,3). El índice de antibioticoterapia previa fue 83 %, con una mediana de tres antibióticos (intervalo: 0­7) en los 30 días previos a la bacteriemia por S. maltophilia. La infección relacionada con el catéter fue la principal fuente de infección (8/12). La mortalidad fue de 4/12; y en dos casos, estuvo asociada con neumonía. S. maltophilia puede considerarse un agente muy invasivo productor de bacteriemia en niños con enfermedad preexistente expuestos a antibióticos durante una hospitalización prolongada.

Stenotrophomonas maltophilia is a multidrug-resistant, Gram-negative, and biofilm-forming pathogen. Information is limited concerning S. maltophilia bacteremia in children. Clinical data and microbiological test results collected in a tertiary children's hospital over a ten-year period were reviewed. Children 0­18 years old who had positive clinical specimen, blood and/or catheter cultures were included. We identified 20 S. maltophiliaisolates from 12 pediatric patients with confirmed infections. The median age was 28 months (range: 3.1-187.3). The rate of previous use of antimicrobial therapy was 83 %. The median antibiotic number was 3 (range: 0­7) within 30 days prior to onset of S. maltophilia bacteremia. Catheter related infection was the main infectious source (66.6 %). The mortality rate was 33.3 %. The death of two non-survivors was associated with pneumonia. S. maltophilia should be considered a breakthrough agent for bacteremia in children with underlying disease exposed to broad-spectrum antibiotics during long-term hospitalization

Clinical characteristics and risk factors of dialysis catheter-related infection in CRRT patients / 中华肾脏病杂志

Objective To explore the clinical characteristics and risk factors of catheterrelated infection in continuous renal replacement therapy (CRRT) patients.Methods The demographic and clinical data of CRRT patients who inserted with double-lumen non-cuffed dialysis catheter at the First Affiliated Hospital of Sun Yat-sen University from January 1,2016 to December 31,2016 were collected.According to the presence or absence of catheter-related infections,they were divided into infected group and uninfected group.Statistics and analysis of the incidence and pathogenic characteristics of catheter-related infections;Comparison of clinical features of infected and uninfected groups;A multivariate Cox proportional hazard model was used to analyze risk factors for catheter-related infections.Results A total of 364 patients with CRRT (437 cases of central venous catheterization) were enrolled in the study.Catheter-related bloodstream infection (CRBSI) and catheterrelated colonization (CRCOL) rates were 3.565 and 2.228 events per 1000 catheter-days.These catheters were associated with higher proportion of inserted in ICU (P=0.007),immunosuppression (P=0.002),receive catecholamine inotropes therapy (P=0.001) and shock (P=0.030).The infection catheters also had shorter indwelling time (P=0.032) and lower level of blood hemoglobin (P=0.017),serum creatinine (P=0.004),blood brain natriuretic peptide (P=0.005) pericatheter use.The most common pathogens were Gram-negative bacteria,especially Acinetobacter baumannii,which caused 37.5％ CRBSI and 20.0％ CRCOL.Multivariate Cox regression model showed female (P=0.029,HR=2.151),diabetes (P=0.016,HR=2.807),receive catecholamine inotropes therapy (P=0.012,HR=2.655),immunosuppression (P=0.037,HR=2.203) were independent risk factors associated with catheterrelated infection.Conclusions The incidence of CRBSI and CRCOL is 3.565 and 2.228 events per 1000 catheter-days CRRT patients in our hospital.The most common pathogen of catherter-related infection is Gram-negative bacteria.Female,diabetes,received catecholamine inotropic drugs,and immunosuppression were independent risk factors associated with catheter-related infection.

Accesos vasculares centrales. Complicaciones en pacientes pediátricos

La necesidad de un rápido y eficaz tratamiento por vía intravenosa a pacientes críticamente enfermos y con imposibilidad de tratamiento por otras vías ha hecho imperioso el acceso a través de las vías venosas centrales (CVC), se ha asociado con eventos adversos que prolongan la estancia hospitalaria, aumentan los costos hospitalarios, pueden agregar morbilidad e incluso mortalidad al paciente. Objetivo: analizar complicaciones de los pacientes con acceso vascular central hospitalizados en los servicios de Urgencias, Terapia Intensiva Pediátrica, Cirugía General y Cuidados Intensivos Neonatales del Hospital de Niños "J.M. de los Ríos", en el período marzo-agosto 2016. Método: Estudio retrospectivo, longitudinal y descriptivo con seguimiento de la evolución según registros de la historia clínica de cada paciente. Se registraron características demográficas, diagnóstico, criterios de indicación, características de los catéteres y su localización, complicaciones infecciosas y no infecciosas, duración y tipo de manipulación del CVC. Resultados: Se estudiaron 54 pacientes en total con CVC determinando que no existe diferencia importante en cuanto al sexo, 52 % masculino frente a 48,1 % femenino. La localización más frecuente fue a nivel de la vena yugular interna derecha en 56 % de casos. En un 41 % no se cumplieron con los criterios de colocación. Se identificó un 37 % de complicaciones de las cuales 22 % fueron de causa no infecciosa destacando la obstrucción como causa más frecuente y un 15 % de etiología infecciosa siendo la bacteriemia la principal causa en un 56 %. Conclusiones: se obtuvo con mayor frecuencia aislamiento de K. pneumoniae y P. aeruginosa. La permanencia de la mayoría de CVC fue mayor de 7 días. No se cumplen con los bundles de inserción ni de mantenimiento. Al analizar los diferentes factores de riesgo para complicación infecciosa, se obtuvo que la duración del catéter incrementa el riesgo de infección.

The need for rapid and effective intravenous treatment of critically ill patients who are unable to treat by other means has made access through the central venous pathways (CVC) imperative, has been associated with adverse events that prolong hospital stay, increase hospital costs, can add morbidity and even mortality to the patient. Objective: To analyze complications of patients with central vascular access hospitalized in the Emergency Services, Pediatric Intensive Care, General Surgery and Neonatal Intensive Care of Children's Hospital "J.M. de Los Rios, in the period March-August 2016. Method: Retrospective, longitudinal and descriptive study with follow-up of the evolution according to records of the clinical history of each patient. Patient demographics, diagnosis, indication criteria, catheter characteristics and location, infectious and noninfectious complications, duration and type of CVC manipulation were recorded. Results: A total of 54 patients with CVC were studied, determining that there is no significant difference in sex, 52 % male versus 48.1 % female. The most frequent localization was at the level of the right internal jugular vein in 56 % of cases. In 41 %, the placement criteria were not met. 37 % of complications were identified, of which 22 % were of non-infectious cause, the most frequent cause being obstruction and 15 % of infectious etiology, with bacteremia being the main cause in 56 %. Conclusions: Among the isolated microorganisms K. pneumoniae and P. aeruginosa were most frequently found. The permanence of the majority of CVC was greater than 7 days. Insertion and maintenance bundles are not met. When analyzing the different risk factors for infectious complication, it was obtained that the duration of the catheter increases the risk of infection.

Catheter-Related Trichosporon asahii Bloodstream Infection in a Neutropenic Patient with Myelodysplastic Syndrome

Because primary antifungal prophylaxis is widely used for immunocompromised hosts, the incidences of unusual fungal infections have increased. Trichosporon asahii has emerged as an important life-threatening opportunistic systemic pathogen because of the increased use of cytotoxic or immunosuppressant agents, along with high mortality rates. Here, we describe a case of catheter-related T. asahii bloodstream infection with multiple septic skin nodules in both the arms and legs of the patient who was in the neutropenic period after allogeneic stem cell transplantation for myelodysplastic syndrome treated with prophylactic ciprofloxacin and itraconazole. We successfully treated her with intravenous voriconazole for more than a month without any complications. Clinicians should consider breakthrough Trichosporon infections when clinical progress in an immunocompromised patient with unexplained infection signs and symptoms does not improve despite proper treatment with antibiotics or various antifungal agents. In addition, voriconazole can be a good treatment choice for achieving better treatment results and prognosis.

Successful Treatment of Catheter Related Blood Stream Infection By Millerozyma farinosa with Micafungin: A Case Report

Millerozyma farinosa (formerly Pichia farinosa) is halotolerant yeast mainly found in food and ubiquitous in the environment. It was a rare yeast pathogen, but it has recently emerged as a cause of fungemia in immunocompromised patients. Optimal therapy for invasive fungal infection by this pathogen remains unclear. We report a case of catheter related blood stream infection caused by M. farinosa in a 71-year-old patient who recovered successfully after removal of the central venous catheter and treatment with micafungin.

Analysis of patients suffering from fungemia of Candida parapsilosis adimitted in geriatric intensive care unit / 中国中西医结合急救杂志

Objective To observe the clinical features of senile patients suffering from fungemia of Candida parapsilosis, and the effect and safety of antifungal therapy in treatment of this disease in geriatric intensive care unit (GICU). Methods The clinical data of patients with fungi positive either in peripheral blood culture or catheter culture admitted to the GICU of Tianjin Medical University General Hospital from November 2012 to June 2015 were retrospectively analyzed, of them 45 cases were of infection of Candida parapsilosis (parapsilosis group) and 15 cases infection of non-Candida parapsilosis (non-parapsilosis group). The clinical features of the two groups were collected, such as sex, age, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, timing of antifungal therapy, number of patients mechanical ventilation, concomitant disease, catheter-related infection, method of catheter-indwelling, levels of creatinine (Cr), hemoglobin (Hb), platelet count (PLT), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), etc.; the differences in above indicators were compared between the two groups; multifactor Cox-regression-analysis was used to analyze the risk factors that could affect the patients' prognosis; the patients' survival rates on 7, 14 and 28-day were calculated and compared between the two groups, and the therapeutic effects of different anti-fungal drugs on patients' survival rates and liver function damage were recorded and compared. Results The non-parapsilosis group had a higher rate in mechanical ventilation than parapsilosis group [73.3% (11/15) vs. 33.3% (15/45), P < 0.05], and in the comparisons of other clinical features, there were no statistical significant differences between the two groups (all P > 0.05). There were no statistical significant differences in survival rates in the duration of 7, 14 and 28 days between the two groups[7 days: 82.2% (37/45) vs. 66.7% (10/15), 14 days: 75.6% (34/45) vs. 60.0% (9/15), 28 days: 66.7% (30/45) vs. 46.7% (7/15), all P > 0.05]. When the patients in parapsilosis group treated with echinocinomycin were compared with those treated with azolol, no statistical significant differences were found between the 2 types of therapy in the survival rates in the duration of 7, 14, and 28 days after treatment [7 days: 100.0% (23/23) vs. 82.4% (14/17), 14 days: 91.3% (21/23) vs. 76.5% (13/17), 28 days: 78.3% (18/23) vs. 70.6% (12/17), all P > 0.05]. Multifactor Cox-regression-analyses showed:diabetes [odds ratio (OR) = 0.268, 95% confidence interval (95%CI) = 0.077 - 0.928, P = 0.038), infection of Candida parapsilosis (OR = 0.260, 95%CI = 0.072 - 0.946, P = 0.041), APACHE Ⅱ score (OR = 1.241, 95%CI = 1.051 - 1.466, P = 0.011) and SOFA score (OR = 1.405, 95%CI = 1.005 - 1.966, P = 0.047) were the risk factors affecting the prognosis of the patients. When the patients in parapsilosis group treated with echinocinomycin were compared with those treated with azolol, there were no statistical significant differences in incidences of aggravation of liver damage and newly developed liver damage (aggravation of liver damage: 18.8% vs. 21.0%, newly developed liver damage: 6.2% vs. 10.5%, both P > 0.05). Conclusion The patients with fungemia in GICU are mainly the infection of Candida parapsilosis, and diabetes, infection of parapsilosis, APACHE Ⅱ score and SOFA score are the risk factors affecting the prognosis of the patients.

A systematic review of the reduction of neonatal PICC catheter associated infection with the frequency of replacement dressing / 中国实用护理杂志

Objective To evaluate the effects on catheter related blood stream infection by different dressing frequency of peripherally inserted central catheter(PICC)with neonates. Methods A systematic review of randomized controlled trials (RCTs) from databases, Data were searched about the transparent dressing replacement frequency for neonatal PICC catheterization. The meta-analysis was performed by using RevMan 5.2 software. Results Nine RCTs were included in a total of 1 730 patients. Meta analysis showed that there was no significant difference in the incidence of PICC puncture dressing, catheter-related infections (including puncture port infection, catheter-related blood flow infection, catheter bacterial colonization) at every 3, 5, and 7 days (P> 0.05). Conclusion the dressing of PICC catheter are replaced will not increase the incidence of catheter-related infections within 7 days, throughout the more appropriate frequency of dressing replacement is once every 7 days.

Objective To investigate the diagnostic value of Heparin-binding protein (HBP) in maintenance hemodialysis patients in catheter-related infections.Methods 75 patients with maintenance hemodialysis were enrolled in the study and divided into observation group(n=45,with catheter-related infections) and control group(n=45,without catheter-related infections).The serum HBP,procalcitonin (PCT) and C-reactive protein (CRP) levels were detected.The values in diagnostic of catheter-related infections and Gram-negative bacterial infections were analyzed by receiver operating characteristic(ROC) curve.Results There were 34 cases of patients infected by Gram-positive bacterial with the rate of 75.6% and 11 cases of patients infected by Gram-negative bacterial with rate of 24.4%.The serum HBP,PCT and CRP levels in observation group were significantly higher than those in control group and the serum HBP,PCT levels of patients infected by Gram-negative bacterial were higher than those of patients infected by Gram-positive bacterial (P27.52 μg/L with sensitivity of 100.0% and specificity of 61.8%.Conclusion Serum HBP,PCT and CRP may be the effective indicators for diagnosis of catheter-related infections,and the HBP has important reference value for diagnosis of Gram-negative bacterial infections.

Prevention of central venous catheter associated infection with hydrocolloid dressings combined GreenCream Dressing:a randomized controlled trial / 中国实用护理杂志

Objective To apply the hydrocolloid dressings and hydrocolloid dressings combined GreenCream Dressing for central venous catheterization fixing, and to explore the effect of hydrocolloid dressings combined GreenCream Dressing in the prevention of venous catheter bacterial colonization and bacterial infection. Methods 470 patients who underwent the Inferior vena cava catheter were divided into 230 patients in the control group and 240 patients in the experimental group. The control group was fixed with hydrocolloid dressings after central venous catheter, and the experimental group was fixed with hydrocolloid dressings combined GreenCream Dressing after central vein catheter. The measurements included catheter bacterial colonization, catheter-related infections (CRIs) and catheter related blood stream infections (CR-BSIs), pathogenic bacteria colonization of the skin. At the same time, the skin safety was also confirmed. Results In the control group, 230 cases were retained for 1 419 catheter-days, and 240 cases in the experimental group were retained for 1 675 catheter-days. Compared with hydrocolloid dressings, hydrocolloid dressing combined GreenCream Dressing could reduce the incidence of CRIs from 1.8‰(3/1 675) to 0.7‰(1/1 675), and CR-BSIs from 2.4‰(4/1 675) to 0.7‰(1/1 675) respectively, with the statistically significant (χ2=6.39, 95%CI 1.30-31.41, andχ2=6.21, 95%CI 1.56-40.82;P<0.05). The results of bacterial colonization, CRIs and CR-BSIs showed that the most common bacteria were Staphylococcus and fungi. At the same time, compared with the hydrocolloid dressing, hydrocolloid dressing combined GreenCream dressing could reduce the incidence of skin pathogenic bacteria colonization, from 41.74%(96/230) to 28.33%(68/230),with the statistically significant (χ2=9.29,P=0.00);There was no difference between the two groups in the field of the incidence of abnormal skin manifestation (χ2=1.23, P=0.30), showing a good safety. Conclusions Hydrocolloid dressing combined GreenCream Dressing would be more effective to prevent bacterial colonization and bacterial infection of central venous catheter in department of neurosurgery.

The incidence and risk factors of catheter-related-thrombosis during induction chemotherapy in acute lymphocytic leukemia children / 中华血液学杂志

Objective@#To investigate the current status of catheter-related-thrombosis (CRT) and the risk factors of Chinese acute lymphocytic leukemia (ALL) children with peripherally inserted central catheter (PICC) .@*Methods@#The clinical data of the 116 inpatients preliminarily diagnosed ALL in the Leukemia Ward of Beijing Children’s Hospital with PICC from 1st March 2014 to 31st December 2014 were collected prospectively.@*Results@#①Refer to the B-ultrasound on the 15th day after catheterization, the incidence of CRT was 28.4% (33/116 cases) , all cases were symptom-free. ②There were no statistical differences in terms of gender, age distribution, degree, immunotype between CRT and CRT-free groups. This study revealed no statistical differences of blood routine test items, coagulation function items, co-infection and catheterization vein between the two groups. While there was significant statistical difference of catheterization side, the frequency of right catheterization was higher in CRT group[75.8% (25/33) vs 55.4% (46/83) , P=0.043]. ③On the 15th day after catheterization, significant statistical difference of D-Dimer between the two groups was revealed[0.18 (0.05-2.45) mg/L vs 0.11 (0.01-5.34) mg/L, P=0.001], while no statistical differences of blood routine test items and other coagulation function items. Multivariate Logistic regression analysis verified catheterization on right was a risk factor of CRT. ④During the observation, there were 3 cases of catheter-related complications other than CRT, all of which were CRI, 2 of them had CRT meanwhile. ⑤The B-ultrasound on the 33rd day after catheterization showed that 73.1% of the cases had reduced thrombosis, 3.8% had growth thrombosis, 23.1% had no obvious change respectively.@*Conclusion@#CRT was a common catheter related complication among ALL children during induction chemotherapy, and CRT cases with symptoms were rare. Catheterization on right was a risk factor for CRT, and regular test of D-Dimer and B ultrasound contributed to detect CRT. Most of the CRT cases had reduced thrombosis without specific management.
