ABSTRACT

Abstract Introduction: Invasive procedures performed by trained nephrologists can reduce delays in making a definitive vascular access, complications, number of procedures on the same patient, and costs for the Public Health System. Objective: to demonstrate that a long-term tunneled central venous catheter (LTCVC) implanted by a nephrologist is safe, effective, and associated with excellent results. Methods: A retrospective study analyzed 149 consecutively performed temporary-to-long-term tunneled central venous catheter conversions in the operating room (OR) from a dialysis facility from March 2014 to September 2017. The data collected consisted of the total procedures performed, demographic characteristics of the study population, rates of success, aborted procedure, failure, complications, and catheter survival, and costs. Results: the main causes of end stage renal disease (ESRD) were systemic arterial hypertension and diabetes mellitus, 37.9% each. Patients had a high number of previous arteriovenous fistula (1.72 ± 0.84) and temporary catheter (2.87 ± 1.9) attempts until a definitive vascular access was achieved, while the preferred vascular site was right internal jugular vein (80%). Success, abortion, and failure rates were 93.3%, 2.7% and 4%, respectively, with only 5.36% of complications (minors). Overall LTCVC survival rates over 1, 3, 6, and 12 months were 93.38, 71.81, 54.36, and 30.2%, respectively, with a mean of 298 ± 280 days (median 198 days). The procedure cost was around 496 dollars. Catheter dysfunction was the main reason for catheter removal (34%). Conclusion: Our analysis shows that placement of LTCVC by a nephrologist in an OR of a dialysis center is effective, safe, and results in substantial cost savings.


Resumo Introdução: Procedimentos invasivos realizados por nefrologistas podem reduzir o número de procedimentos no mesmo paciente, complicações e atrasos na obtenção de acesso vascular definitivo, bem como proporcionar menor custo para o Sistema de Saúde. Objetivo: Demonstrar a segurança, a eficácia e os resultados dos implantes de cateteres venosos centrais de longa permanência (CLP) realizados por nefrologista sem fluoroscopia. Métodos: Estudo retrospectivo que analisou 149 implantes de CLP por nefrologista no centro cirúrgico de clínica de diálise, sem auxílio de fluoroscopia, no período de março/2014 a setembro/2017. Os dados coletados consistiram em: características demográficas da população estudada, taxas de sucesso, procedimento abortado, falha no procedimento, complicações observadas, patência do cateter e custos. Resultados: Houve um elevado número de tentativas fístulas arteriovenosas (1,72 ± 0,84) e de cateter de curta permanência (2,87 ± 1,9) até a realização de um acesso vascular definitivo. O sítio vascular preferido foi a veia jugular interna direita (80%). Taxas de sucesso, procedimentos abortados e falhas foram de 93,3%, 2,7% e 4,0%, respectivamente, com apenas 5,36% de pequenas complicações. A patência dos CLP com 1, 3, 6 e 12 meses foram de 93,38%, 71,81, 54,36% e 30,2%, respectivamente, com média de 298 ± 280 dias (mediana 198 dias). Os custos dos procedimentos foram em torno de US$ 496. Disfunção foi o principal motivo da remoção do cateter (34%). Conclusão: Nossa análise mostra que o implante de CLP por nefrologista no centro cirúrgico de clínica de diálise é eficaz e seguro e está associado à redução significativa de custos.

ABSTRACT

Abstract Introduction: Indications for cardiac devices have been increasing as well as the need for lead extractions as a result of infections, failed leads and device recalls. Powered laser sheaths, with a global trend towards the in-creasingly technological tools, meant to improve the procedure's outcome but have economic implications. Objective: The aim of this study is to demonstrate the experience of a Bra-zilian center that uses simple manual traction in most lead removals per-formed annually, questioning the real need for expensive and technically challenging new devices. Methods: This retrospective observational study included 35 patients who had a transvenous lead extraction in the period of a year between January 1998 and October 2014 at Hospital de Messejana Dr. Carlos Alberto Studart Gomes, in Fortaleza, CE, Brazil. Data were collected through a records review. They were evaluated based on age, type of device, dwelling time, indication for removal, technique used and immediate outcomes. Results: The median dwelling time of the devices was 46.22 months. Infec-tion, lead fracture and device malfunction were the most common indica-tions. Simple traction was the method of choice, used in 88.9% of the pro-cedures. Manual traction presented high success rates, resulting in com-plete removal without complications in 90% of the cases. Conclusion: This article suggests that lead extraction by simple manual traction can still be performed effectively in countries with economic diffi-culties as a first attempt, leaving auxiliary tools for a second attempt in case of failure or contraindications to the simple manual traction technique.

ABSTRACT

Abstract Introduction: Vascular access (VA) in hemodialysis (HD) is essential to end-stage renal disease (ESRD) patients survival. Unfortunately, after some years in HD program, a significant number of patients may develop VA failure for many reasons. In this situation, arterial venous fistula (AVF) confection or catheters placement in traditional vascular sites (jugular, femoral or subclavian) are not feasible. In this scenario, translumbar tunneled dialysis catheter (TLDC) may be a salvage option. Objectives: To describe placement technic, complications, and patency of 12 TLDC. Methods: A retrospective study was performed to analyze 12 TLDC placement in an angiography suite using fluoroscopic guidance at the University Hospital of the Rio Grande do Norte Federal University from January 2016 to October 2017. The data collected of the total procedures performed consisted of demographic characteristics, success rates, observed complications, patient survival, and catheter patency. Results: All 12 TLDC were placed with success; there were only 2 significant periprocedure complications (major bleeding and extubation failure); 41.6% of patients presented a catheter-related first infection after 98 ± 72.1 (6-201) days, but catheter withdrawal was not necessary, mean total access patency was 315.5 (range 65 - 631) catheter-days, and catheter patency at 3, 6 and 12 months was 91 %, 75%, and 45%. Conclusion: TLDC is an option for patients with VA failure, improving survival and acting as a bridge for renal transplantation.


Resumo Introdução: O acesso vascular (AV) para hemodiálise (HD) é crucial para os pacientes portadores de doença renal crônica (DRC) estágio V. Infelizmente, com o passar dos anos, um percentual não desprezível desses enfermos evolui para falência de AV por diversos motivos, o que impossibilita a confecção de novas fístulas arteriovenosas (FAV) ou o implante de cateteres venosos centrais nos sítios de punções tradicionais. Nesse cenário, o implante de cateteres translombares para hemodiálise (CTLHD) em veia cava inferior ganha destaque como medida salvadora. Objetivos: Relatar uma série de 12 casos de implante de CTLHD, sua técnica de implante, patência e complicações. Métodos: Estudo retrospectivo que analisou 12 implantes de CTLHD por radiologista intervencionista no setor de hemodinâmica do Hospital Universitário da Universidade Federal do Rio Grande do Norte (UFRN), no período de janeiro/2016 a outubro/2017. Os dados coletados consistiram em: características demográficas da população estudada, taxa de sucesso, complicações observadas, sobrevida dos pacientes, patência do cateter e desfechos clínicos. Resultados: Todos os 12 CTLHD foram implantados e utilizados com sucesso; ocorreram apenas 2 complicações associadas ao procedimento (sangramento e falha na extubação); 41,6% dos pacientes apresentaram infecção relacionada ao cateter após 98 ± 72,1 dias (6-201 dias), mas não houve necessidade de remoção; e a patência foi de 315,5 cateteres-dia (65-631 dias). Conclusão: O CTLHD é uma opção para pacientes com falência de acesso vascular, prolongando a sobrevida dos pacientes e atuando como ponte para o transplante renal.

ABSTRACT

Representantes de la Sociedad Argentina de Infectología (SADI) y la Sociedad Argentina de Terapia Intensiva (SATI) acordaron la elaboración de recomendaciones de diagnóstico, tratamiento y prevención de la infección del tracto urinario asociada a sonda vesical (ITU-SV). La metodología utilizada fue el análisis de la bibliografía publicada en 2006-2016, complementada con la opinión de expertos y datos epidemiológicos locales. En este documento se pretende ofrecer herramientas básicas de optimización de diagnóstico en base a criterios clínicos y microbiológicos, orientación en los esquemas antibióticos empíricos y dirigidos, y promover las medidas efectivas para reducir el riesgo de ITU-SV. Se destaca la preocupación por el control y tratamiento inadecuados de la ITU-SV, en particular el uso indiscriminado de antimicrobianos y la importancia de garantizar la mejora en las prácticas diarias. Se establecen pautas locales para mejorar la prevención, optimizar el diagnóstico y tratamiento de la ITU-SV, y así disminuir la morbimortalidad, los días de internación, los costos y la resistencia a antibióticos debidos al mal uso de los antimicrobianos.


Representatives of the Argentine Society of Infectious Diseases (SADI) and the Argentine Society of Intensive Therapy (SATI) issued the present recommendations on diagnosis, treatment, and prevention of catheter associated urinary tract infection (CA-UTI). Articles published during 2006-2016 were analyzed in the light of experts' opinion and local data. This document aims to offer basic strategies to optimize the diagnosis based on clinical and microbiological criteria, provide guidance in empirical and targeted antibiotic schemes, and promote effective measures to reduce the risk of CA-UTI. The joint work of both societies highlights the experts' concern about the mismanagement of CA-UTI, which is associated to the indiscriminate use of antimicrobials, and the importance of improving daily practices of CA-UTI management. Through these recommendations, local guidelines are established to optimize the diagnosis, treatment and prevention of CAUTI in order to reduce morbimortality, days of hospitalization, costs and antibiotic resistance due to the misuse of antimicrobials.

ABSTRACT

ABSTRACT Objective: To evaluate the safety and feasibility of the use of indwelling pleural catheters (IPCs) in patients with malignant pleural effusion (MPE). Methods: We prospectively collected data from patients with MPE undergoing IPC placement between January of 2014 and July of 2015. All patients submitted to IPC placement had a life expectancy > 30 days, in accordance with the MPE treatment guidelines established by the British Thoracic Society. The data collected included gender, age, body mass index, primary cancer site, duration of IPC drainage, IPC-related complications, length of hospital stay, pleural effusion recurrence, and occurrence of spontaneous pleurodesis. Results: A total of 19 patients underwent IPC placement during the study period. Median overall survival after IPC insertion was 145 days. The median follow-up among the surviving patients was 125 days (range, 53-485 days), and the median time between catheter insertion and removal was 31 days (range, 2-126 days). There were IPC-related complications in 5 patients (26.2%), and spontaneous pleurodesis was achieved in 8 (42.0%). Among those 8 patients, the IPC was removed between days 30 and 126 in 4, and spontaneous pleurodesis occurred within the first 30 days in 4. Conclusions: The use of IPCs seems to be feasible and safe in patients with MPE.


RESUMO Objetivo: Avaliar a segurança e a viabilidade do uso de cateter pleural de longa permanência (CPLP) em pacientes com derrame pleural neoplásico (DPN). Métodos: Dados referentes a pacientes com DPN que receberam CPLP entre janeiro de 2014 e julho de 2015 foram colhidos prospectivamente. Todos os pacientes que receberam CPLP tinham expectativa de vida > 30 dias, em conformidade com as diretrizes de tratamento de DPN da Sociedade Torácica Britânica. Foram colhidos dados sobre sexo, idade, índice de massa corporal, local do câncer primário, tempo de drenagem com o CPLP, complicações relacionadas com o CPLP, tempo de internação hospitalar, recidiva do derrame pleural e ocorrência de pleurodese espontânea. Resultados: Dezenove pacientes receberam CPLP durante o período de estudo. A mediana de sobrevida global após a inserção do CPLP foi de 145 dias. A mediana de tempo de acompanhamento dos pacientes sobreviventes foi de 125 dias (variação: 53-485 dias), e a mediana de tempo decorrido entre a inserção e a remoção do cateter foi de 31 dias (variação: 2-126 dias). Houve complicações relacionadas com o CPLP em 5 pacientes (26,2%) e pleurodese espontânea em 8 (42,0%). Nesses 8 pacientes, o CPLP foi retirado entre os dias 30 e 126 em 4, e a pleurodese espontânea ocorreu nos primeiros 30 dias em 4. Conclusões: O uso de CPLP parece ser viável e seguro em pacientes com DPN.

ABSTRACT

Introdução: Durante o tratamento ambulatorial da criança ou adolescente com doença oncohematológica são necessárias inúmeras internações hospitalares e o estabelecimento de um acesso venoso vascular de longa permanência se faz necessário para realização do tratamento quimioterápico. Objetivos: Identificar o perfil clínico de crianças/adolescentes com doença oncohematológica e as características dos cateteres utilizados para realização do seu tratamento; Identificar as principais complicações a partir da manipulação destes cateteres; Elaborar fluxograma de Terapia Lock em cateter totalmente implantado; Elaborar rotina de manipulação do cateter totalmente implantado; Aprimorar a ficha de vigilância epidemiológica que contemple os diferentes tipos de procedimentos realizados durante a manipulação dos cateteres; Realizar um curso de manipulação segura de Cateter Totalmente Implantado. Metodologia: Estudo descritivo, com abordagem quantitativa de 78 fichas de vigilância epidemiológica dos cateteres totalmente implantados e dos cateteres epicutâneo; o cenário do estudo foi um ambulatório de oncohematologia pediátrica localizado em um Hospital Federal do município do Rio de Janeiro, os dados foram coletados em agosto 2015. O projeto foi aprovado com o parecer de número: 1.213.979. Resultados: Os dados levantados nos mostraram que as crianças que realizam tratamento hematológico tiveram um ou mais cateteres. Observou-se que n=32 (59%) dos portadores de cateter totalmente implantado eram do sexo masculino, e n=sete (53%) dos portadores de cateter epicutâneo eram do sexo feminino, a idade variava entre 10 a 16 anos, o principal diagnóstico foi leucemia linfoide aguda em ambos. A média de utilização do cateter totalmente implantado foi 303 dias, enquanto do cateter epicutâneo foi 55 dias, o término do tratamento é o principal motivo de retirada de ambos. A falta de preenchimento de informações nas fichas foi limitador desta pesquisa. Conclusão: Conclui-se que os dois dispositivos levantados por esta pesquisa, desde que indicados e manipulados de forma correta, conseguem cumprir com o objetivo proposto que é proporcionar um tratamento ininterrupto e seguro para o paciente. Havia necessidade de padronizar a rotina de manipulação do cateter totalmente implantado afim de que toda a equipe envolvida realizasse as técnicas de forma segura e eficaz reduzindo assim as chances de complicações relacionadas a este dispositivo.

ABSTRACT

ABSTRACT Objective To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein. Methods Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies. Results In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients. Conclusion Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others.


RESUMO Objetivo Avaliar prospectivamente segurança perioperatória, complicações precoces e grau de satisfação de pacientes submetidos ao implante de cateteres centrais de inserção periférica pela veia basílica. Métodos Foram acompanhados prospectivamente e submetidos ao implante de cateteres de longa permanência de inserção periférica, entre novembro de 2013 e junho de 2014, 35 pacientes consecutivos com doença oncológica ativa necessitando de quimioterapia. Os procedimentos foram realizados em centro cirúrgico por uma mesma equipe composta por três cirurgiões vasculares. Os desfechos primários avaliados foram as complicações pós-operatórias precoces, ocorridas em até 30 dias após o implante. A avaliação do grau de satisfação foi realizada com base na aplicação de um questionário específico já utilizado em estudos prévios. Resultados Em todos os casos, a punção ecoguiada da veia basílica foi possível, e o procedimento foi concluído com sucesso. As complicações precoces observadas incluíram um caso de tromboflebite de basílica e um de infecção de bolsa, ambos tratados clinicamente sem necessidade de retirada do dispositivo. Dos 35 pacientes interrogados, 33 (94,3%) recomendariam o dispositivo para outras pessoas. Conclusão A implantação do port braquial é uma opção factível, com baixo risco intraoperatório e taxas semelhantes de complicações pós-operatórias imediatas quando comparada a dados já existentes da técnica convencional. Os pacientes estudados apresentaram-se satisfeitos com o dispositivo e recomendariam o procedimento para outras pessoas.

ABSTRACT

La canalización de los vasos umbilicales es un procedimiento frecuente en las unidades de cuidados intensivos neonatales, especialmente en los recién nacidos de muy bajo peso al nacer. Raras veces el catéter arterial umbilical se rompe; los fragmentos retenidos pueden provocar trombosis, infección, embolización distal e incluso la muerte. En este artículo, describimos el caso de un recién nacido con isquemia bilateral, clínicamente significativa, de las extremidades que se manifestó después de la extracción de un catéter arterial umbilical roto. Estaba recibiendo tratamiento vasodilatador junto con fibrinolíticos y anticoagulantes. La evolución fue favorable.


Umbilical vessel catheterization is a common procedure in Neonatal Intensive Care Units, especially in very low birthweight infants. Rarely, umbilical artery catheters break, and the retained fragments can cause thrombosis, infection, distal embolization, and even death. Herein, we describe a neonate with clinically significant bilateral limb ischemia developing after removal of a broken umbilical artery catheter. He was under vasodilator treatment in addition to fibrinolytic and anticoagulants. The evolution was favourable.

ABSTRACT

Resumo Atualmente, cateteres venosos permanentes (CVCp) estão se tornando cada vez mais uma alternativa de acesso vascular de longa permanência para pacientes nos quais o acesso arteriovenoso não pode ser confeccionado, sendo a oclusão trombótica complicação mecânica comum. Essa complicação pode ocasionar mudanças frequentes dos locais de cateter, eliminando os sítios vasculares. Este estudo teve como objetivo realizar uma revisão narrativa do manejo da oclusão trombótica de CVCp na população em HD. O tratamento da trombose de CVC consiste em infusão de solução salina ou na administração de trombolíticos como plasminogênio tecidual ativado, reteplase ou uroquinase. Há poucos estudos sobre o uso de alteplase em CVCp obstruídos na população em diálise, e todos eles relatam sucesso entre 80 a 95% dos casos com uso de trombolítico na dose de 1 mg/ml. Por tratar-se de medicamento de custo elevado, estudos sugerem que a criopreservação e o fracionamento da alteplase tornam o uso financeiramente viável.


Abstract Currently, permanent catheters (pCVC) are becoming an alternative vascular access for long-stay patients in whom arteriovenous access cannot be made. Occlusion is a commun mechanical complication related to pCVC, leading to inadequate dialysis dose and frequent changes of local catheter location, which can cause exclusion of vascular sites. The aim of this study was to perform a narrative review of treatment of pCVC thrombotic occlusion in HD patients. The treatment of CVCP thrombosis typically consists on the saline infusion or administration of thrombolytics such as tissue plasminogen activated, reteplase and urokinase. There are few studies on the use of alteplase in pCVC clogged in oncology area and in dialysis population, and they all report success with the use of thrombolytic therapy ranging from 80-95% of cases, using 1mg/ml. Due to the high cost of alteplase, studies have suggested that cryopreservation and fractionated alteplase dose have made its use financially viable.

ABSTRACT

OBJECTIVE: To determine whether mobility therapy is associated with central or peripheral catheter-related adverse events in critically ill patients in an ICU in Brazil. METHODS: A retrospective analysis of the daily medical records of patients admitted to the Clinical Emergency ICU of the University of São Paulo School of Medicine Hospital das Clínicas Central Institute between December of 2009 and April of 2011. In addition to the demographic and clinical characteristics of the patients, we collected data related to central venous catheters (CVCs), hemodialysis (HD) catheters and indwelling arterial catheters (IACs): insertion site; number of catheter days; and types of adverse events. We also characterized the mobility therapy provided. RESULTS: Among the 275 patients evaluated, CVCs were used in 49%, HD catheters were used in 26%, and IACs were used in 29%. A total of 1,268 mobility therapy sessions were provided to patients while they had a catheter in place. Catheter-related adverse events occurred in 20 patients (a total of 22 adverse events): 32%, infection; 32%, obstruction; and 32%, accidental dislodgement. We found that mobility therapy was not significantly associated with any catheter-related adverse event, regardless of the type of catheter employed: CVC-OR = 0.8; 95% CI: 0.7-1.0; p = 0.14; HD catheter-OR = 1.04; 95% CI: 0.89-1.21; p = 0.56; or IAC-OR = 1.74; 95% CI: 0.94-3.23; p = 0.07. CONCLUSIONS: In critically ill patients, mobility therapy is not associated with the incidence of adverse events involving CVCs, HD catheters, or IACs. .


OBJETIVO: Verificar se a realização de fisioterapia com foco na reabilitação motora está associada a eventos adversos em cateteres centrais e periféricos em uma UTI brasileira. MÉTODOS: Análise retrospectiva das fichas de evolução diária dos pacientes internados, de dezembro de 2009 a abril de 2011, na UTI de Emergências Clínicas do Instituto Central do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Além das características clínicas e demográficas dos pacientes, foram coletados dados referentes aos cateteres venoso central (CVC), de hemodiálise (HD) e de pressão arterial invasiva (PAi), tais como sítio de inserção, tempo de permanência e eventos adversos relacionados, bem como à caracterização da fisioterapia motora realizada. RESULTADOS: De um total de 275 pacientes, 49% utilizaram CVC, 26%, cateter de HD e 29%, cateter de PAi em algum momento da internação. Um total de 1.268 sessões de fisioterapia motora ocorreu enquanto o paciente apresentava algum tipo de cateter inserido. Os eventos adversos relacionados à inserção dos dispositivos ocorreram em 20 pacientes, totalizando 22 ocorrências: 32% de infecção, 32% de obstrução e 32% de retirada acidental. Neste estudo, verificou-se que não existe relação entre eventos adversos nos cateteres e a realização de fisioterapia motora: fisioterapia motora e CVC - OR = 0,8; IC95%: 0,7-1,0; p = 0,14; fisioterapia motora e cateter de HD - OR = 1,04; IC95%: 0,89-1,21; p = 0,56; e fisioterapia motora e cateter de PAi - OR = 1,74; IC95%: 0,94-3,23; p = 0,07. CONCLUSÕES: A realização de fisioterapia motora em pacientes críticos não está relacionada à incidência de eventos adversos em CVC, cateteres de HD e cateteres de PAi. .

ABSTRACT

Purple urine bag syndrome is an uncommon but particularly striking phenomenon observed in people with urinary catheters and co-existent urinary tract infections. A chemical reaction between plastic and certain bacterial enzymes results in an intense purple urine color. We report a 72 year-old male with a cystostomy. A purple coloration of his urinary drainage bag and tubing was noted in the context of a urinary tract infection caused by Citrobacter freundii.

ABSTRACT

Introdução: A doença renal crônica é uma doença cuja prevalência tem aumentado no Brasil. A hemodiálise é sua principal modalidade terapêutica e tem, como via de acesso preferencial, a confecção de fístula arteriovenosa. Apesar disso, muitos pacientes necessitam do uso de cateteres duplo-lúmen, seja como acesso temporário ou permanente. Complicações vasculares relacionadas a este procedimento podem ocorrer, sendo o melhor método de avaliação não invasiva a análise ecográfica. Objetivo: Analisar as complicações pelo uso do cateter duplo-lúmen em pacientes com doença renal crônica, em hemodiálise, no Hospital Santa Casa de Misericórdia de Ponta Grossa, PR, por meio do eco-Doppler. Métodos: Estudo observacional, analítico, tipo caso-controle, com obtenção dos dados por TASY®, questionário, exame físico direcionado e exame de imagem (eco-Doppler). Resultados: Nenhuma das variáveis analisadas se mostrou significativa isoladamente como preditora de repercussão vascular no eco-Doppler, que detectou alterações em 31,25% dos casos. O exame físico se mostrou de péssima acurácia em relação ao eco-Doppler na detecção das complicações (K = -0,123). Conclusão: Concluímos que as repercussões vasculares do uso de CDL são frequentes (31,25%), manifestando-se na forma de oclusões com/sem recanalização e estenoses. Sendo assim, é necessária uma análise prévia do sítio de inserção com o eco-Doppler, a fim de se evitar procedimentos desnecessários e com possíveis complicações. .


Introduction: Chronic renal failure is a disease which prevalence has been increasing in Brazil. Hemodialysis is their primary therapeutic modality and arterio-venous fistula their preferential access. Nevertheless, many patients require the use of double-lumen catheters, either as permanent or temporary access. Vascular complications related to this procedure may occur, and their best method of non-invasive analysis is ultrasound analysis. Objective: To analyze the complications by the use of double-lumen catheter in patients with chronic kidney disease on hemodialysis, at "Santa Casa de Misericordia de Ponta Grossa" hospital, through eco-Doppler exam. Methods: Observational research, analytical, case-control type, to obtain data we used TASY®, interview, physical exam and imaging (eco-Doppler). Results: None of the variables was significant isolated as a predictor of vascular impact in eco-Doppler, which detected changes in 31.25% of the cases. Physical exam showed poor accuracy compared to Doppler capacity to detect complications (K = -0.123). Conclusion: We conclude that the vascular effects of the use of CDL are frequent (31.25%). Manifesting itself in the form of occlusions with/without recanalization and stenoses. This leads us to required a prior analysis of the insertion site with Doppler, in order to avoid unnecessary procedures and possible complications. .

ABSTRACT

Ralstonia mannitolilytica junto con Ralstonia pickettii han sido asociadas con brotes hospitalarios relacionados con la contaminación de algún dispositivo o fluido. El objetivo de este trabajo fue describir un brote por R. mannitolilytica a partir de bacteriemias asociadas a catéteres implantables y semiimplantables ocurrido en un hospital pediátrico de alta complejidad y evaluar la utilidad del empleo de métodos moleculares para su investigación.Se detectó la presencia de bacilos gram negativos no fermentadores, con igual antibiotipo, en hemocultivos y retrocultivos a partir de dos pacientes que tenían catéteres implantables y estaban atendidos en una misma área del hospital. Se realizaron estudios microbiológicos de muestras de frascos de heparina, soluciones de dextrosa y soluciones antisépticas con resultado negativo. Algunos pacientes tuvieron signos y/o síntomas clínicos de bacteriemia al habilitar los catéteres para su uso. Se citaron para su estudio a todos los pacientes que habían tenido un procedimiento de apertura y cierre de catéter durante las fechas cercanas a los hallazgos en hemocultivos (N expuestos = 45). Ocurrieron 17 casos (infectados), a partir de los cuales se analizaron 23 aislamientos, en los que se pudo documentar la presencia de R. mannitolilytica (23 aislamientos). Por métodos moleculares se determinó que los aislamientos provenientes de muestras de pacientes involucrados en el brote se encontraban estrechamente relacionados y podrían representar una misma cepa o clon. Por evidencia circunstancial se consideró a la "solución heparínica de cierre" como fuente posible del brote (AU)


Both Ralstonia mannitolilytica and Ralstonia pickettii have been associated with hospital outbreaks due to device or fluid contamination. The aim of this study was to describe an implantable- or semi-implantable-catheter-related bacteremia outbreak by R. mannitolilytica in a tertiary-care hospital and to assess the usefulness of molecular analysis for the identification of the organism. Non-fermenting gram-negative bacilli, with identical antibiotypes, were detected in hemocultures of two patients with implantable catheters in the same hospital area. Microbiological studies of heparin and dextrose and antiseptic solution vials were negative. Some of the patients had clinical signs and/or symptoms of bacteremia when the catheter was prepared for use. All patients who underwent a procedure of accessing or locking the port of the catheter around the time of the positive hemoculture findings were contacted (N exposed = 45). Seventeen infections were detected, of which 23 isolates were analyzed. The presence of R. mannitolilytica was recorded in 23 isolates. Molecular analysis showed that the isolates from the samples of the patients involved in the outbreak were closely related and might represent the same strain or clone. Circumstantial evidence suggested that the heparin-lock solution may have been the source of the outbreak (AU)

ABSTRACT

OBJECTIVE: The purpose of this study was to determine the incidence and risk factors of infections associated with implantable venous access ports (IVAPs). MATERIALS AND METHODS: From August 2003 through November 2011, 1747 IVAPs were placed in our interventional radiology suite. One hundred forty four IVAPs were inserted in patients with hematologic malignancy and 1603 IVAPs in patients with solid tumors. Among them, 40 ports (23 women and 17 men; mean age, 57.1 years; range, 13-83) were removed to treat port-related infections. We evaluated the incidence of port-related infection, patient characteristics, bacteriologic data, and patient progress. Univariable analyses (t test, chi-square test, and Fisher's exact test) and multiple logistic regression analyses were used to determine the risk factors for IVAP related infection. RESULTS: Overall, 40 (2.3%) of 1747 ports were removed for symptoms of infection with an incidence rate of 0.067 events/1000 catheter-days. According to the univariable study, the incidences of infection were seemingly higher in the patients who received the procedure during inpatient treatment (p = 0.016), the patients with hematologic malignancy (p = 0.041), and the patients receiving palliative chemotherapy (p = 0.022). From the multiple binary logistic regression, the adjusted odds ratios of infection in patients with hematologic malignancies and those receiving palliative chemotherapy were 7.769 (p = 0.001) and 4.863 (p = 0.003), respectively. Microorganisms were isolated from 26 (65%) blood samples, and two of the most causative organisms were found to be Staphylococcus (n = 10) and Candida species (n = 7). CONCLUSION: The underlying hematologic malignancy and the state of receiving palliative chemotherapy were the independent risk factors of IVAP-related infection.

MÉTODOS: foram colocados 815 cateteres totalmente implantáveis em 793 pacientes submetidos ao regime de quimioterapia preferencialmente utilizando-se a veia cefálica direita. Foram avaliadas as complicações precoces e tardias. RESULTADOS: a análise retrospectiva mostrou duração média dos cateteres de 339 dias. Em 733 (90%) cateteres não se observou nenhuma complicação. Entre as complicações precoces observamos um pneumotórax, um mau posicionamento de cateter, uma punção arterial, um sangramento, um hemotórax e hemomediastino e seis hematomas na loja de implantação. Entre as complicações tardias, ocorreram 35 infecções relacionadas ao cateter, dez infecções no sítio cirúrgico, seis obstruções e 20 tromboses. Foram retirados 236 cateteres, 35 devido às complicações e 201 por final de tratamento. CONCLUSÃO: os cateteres totalmente implantáveis para quimioterapia são meios seguros para a administração de substâncias, em vista do baixo número de complicações observadas neste estudo.


OBJECTIVE: To retrospectively study the results obtained with the implementation of totally implantable catheters in patients undergoing chemotherapy. METHODS: 815 totally implantable catheters placed in 793 patients undergoing chemotherapy regimen, preferably using the right cephalic vein. We evaluated early and late complications. RESULTS: The retrospective analysis showed an average duration of 339 days of the catheters. In 733 (90%) catheters there was no observe complication. Among early complications we observed one pneumothorax, one bad positioning of the catheter, one arterial puncture, one bleeding, one hemothorax and hemomediastinum and six hematomas in the implantation site. As for late complications, there were 35 catheter-related infections ten, infections in the surgical site, six obstructions and 20 thromboses. We removed 236 catheters, 35 due to complications and 201 by the end of treatment. CONCLUSION: totally implantable catheters for chemotherapy are a safe means for the administration of substances, in view of the low number of complications observed in this study.

ABSTRACT

A fragmentação de um cateter intravascular foi primeiramente publicada em 1954 e, desde então, observamos notável evolução das técnicas de retirada de corpo estranho intravascular. A descrição pioneira de remoção não cirúrgica de corpo estranho data de 1964, com o relato da retirada de fragmento de fio-guia com auxílio de um fórceps de biópsia para broncoscópio. Apesar da disponibilidade de variados dispositivos dedicados, por vezes, para se ter sucesso, é necessária a adaptação de materiais. Relatamos aqui o caso de uma portadora de cateter Port-a-Cath em veia subclávia esquerda, implantado 5 anos antes, que rompeu a porção intravascular durante sua retirada, tendo sido removido com sucesso por via percutânea.


The first report of an intravascular catheter fragmentation was published in 1954 and ever since we have observed a remarkable evolution in the techniques of intravascular foreign body removal. The pioneer description of non-surgical foreign body removal dates back to 1964, with the report of a guidewire fragment withdrawal using a bronchoscopy biopsy forceps. Despite the availability of several dedicated devices, materials may have to be adapted at times to achieve technical success. We report the case of a patient with a Port-a-Cath catheter in the left subclavian vein, which had been placed 5 years before and whose intravascular portion was broken during withdrawal. It was successfully removed using the percutaneous approach.

ABSTRACT

BACKGROUND/AIMS: The high mortality attributable to persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in spite of glycopeptide treatment has heightened the need for early detection and intervention with alternative agents. The purpose of this study was to determine the clinical characteristics of and risk factors for persistent MRSA bacteremia. METHODS: All first episodes of significant MRSA bacteremia at a 710-bed academic medical center from November 2009 through August 2010 were recorded. Blood cultures were conducted at 3 days and every 2 to 3 days thereafter until clearance. Clinical characteristics and outcomes were compared between persistent MRSA bacteremia (> or = 7 days) and nonpersistent MRSA bacteremia (< or = 3 days). RESULTS: Of 79 patients with MRSA bacteremia during the study period, 31 (39.2%) had persistent MRSA bacteremia. The persistent MRSA bacteremia group had significantly higher 30-day mortality than the nonpersistent MRSA bacteremia group (58.1% vs. 16.7%, p < 0.001). Multivariate analysis indicated that metastatic infection at presentation (odds ratio [OR], 14.57; 95% confidence interval [CI], 3.52 to 60.34; p < 0.001) and delayed catheter removal in catheter-related infection (OR, 3.80; 95% CI, 1.04 to 13.88; p = 0.004) were independent predictors of persistent MRSA bacteremia. Patients with a time to blood culture positivity (TTP) of < 11.8 hours were at increased risk of persistent MRSA bacteremia (29.0% vs. 8.3%, p = 0.029). CONCLUSIONS: High mortality in patients with persistent MRSA bacteremia was noted. Early detection of metastatic infection and early removal of infected intravascular catheters should be considered to reduce the risk of persistent MRSA bacteremia. Further studies are needed to evaluate the role of TTP for predicting persistent MRSA bacteremia.

ABSTRACT

Aim of The Study: A totally implantable venous access port (TIVAP) has become an essential prerequisite for many chemotherapy protocols. It is serving its purpose very well, but its use is not without complications. We are presenting our experience with these devices (TIVAPs). Subjects and Methods: We retrospectively reviewed the totally implantable venous access ports in 81 patients at our hospital between January 2009 and March 2011 for long-term problems which include postoperative and follow-up problems, excluding the immediate complications which occur at the time of insertion. Results: Catheter malfunction was the most common complication (9.87%, 0.40/1000 device-days of use/observation). Catheter-related bloodstream infections were present in 5 (6.17%) patients (0.25/1000 device-days of use/observation). The mean life of the catheter was 246 days. Only 11.1% ports required removal during the treatment period. Overall, patients either completed treatment (82.8%) or died (6.1%) while receiving treatment. Conclusion: TIVAPs provide safe and reliable vascular access for patients on chemotherapy but require utmost care by a dedicated team of trained medical professionals and paramedics experienced with the use of such ports, in order to minimize the complications and their continued use while administering treatment.
