ABSTRACT

OBJECTIVE@#To study the clinical features of pericardial effusion caused by central venous catheterization in preterm infants.@*METHODS@#A retrospective analysis was performed on 11 preterm infants with pericardial effusion caused by central venous catheterization. Their catheterization features, manifestations, treatment, and prognosis were analyzed.@*RESULTS@#A total of 11 preterm infants (11/2 599, 0.42%) developed pericardial effusion, with a mean gestational age of (30.1±2.6) weeks and a mean birth weight of (1 240±234) g. Pericardial effusion mostly occurred within 4 days after central venous catheterization (10 cases, 91%). The main manifestations included poor response (6/11, 55%), cyanosis (5/11, 45%), increased respiratory rate (6/11, 55%), increased heart rate (6/11, 55%), aggravated dyspnea (5/11, 45%), and muffled heart sound (5/11, 45%). At the time of disease progression, 7 preterm infants (64%) had a deep position of the end of the catheter, 3 preterm infants (27%) had a correct position, and 1 preterm infant (9%) had a shallow position. Five preterm infants (45%) experienced cardiac tamponade, among whom 4 underwent pericardiocentesis. Seven preterm infants were given conservative medical treatment. Among the 11 children, 2 (18%) died and 9 (82%) improved.@*CONCLUSIONS@#Pericardial effusion caused by central venous catheterization mostly occurs in the early stage of catheterization and has critical clinical manifestations. Pericardiocentesis is required for cardiac tamponade, and early diagnosis and intervention can effectively improve prognosis.

ABSTRACT

Peripherally inserted central catheter (PICC) has been widely used in the neonatal intensive care unit (NICU) in recent years, but there are potential risks for complications related to PICC. Based on the current evidence in China and overseas, the operation and management guidelines for PICC in neonates were developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) in order to help the NICU staff to regulate the operation and management of PICC.

ABSTRACT

Introducción: La cateterización venosa central es un procedimiento usual en Unidades de Cuidados Intensivos (UCI). El ultrasonido (US) para guiar la cateterización, ofrece ventajas, permitiendo tener una imagen topográfica precisa del vaso, reduciendo las complicaciones, el tiempo y el número de punciones. Objetivo: determinar, si la US en la colocación de catéteres venosos centrales (CVC), podría disminuir el número de punciones y lograr la cateterización exitosa. Población y métodos: Estudio descriptivo, prospectivo de los CVC colocados mediante punción guiada por US, en una UCI polivalente del Hospital de Pediatría Juan P. Garrahan, entre el año 2018 al 2019. Población: pacientes de 1 mes a 18 años que requirieron colocación de un CVS por US. Se consideró significativo un valor de p< 0.05. Resultados: VYI en 66 pacientes (43,5%), VF fue en 86 pacientes (56,5%). 86 (56,5%) CVC, fueron insertados en el primer intento y 66 (43,5%), requirieron más de un intento. Las inserciones en VYI fueron exitosas en el primer intento en 46 pac. (53,5%) 20 pac. requirieron más de un intento (30,3%) p 0,004 OR 0,37 (IC 95% 0,18-0,78. En <6 meses los CVC colocados en VYI tuvieron menos riesgo de requerir más de un intento, con respecto a aquellos en los cuales se eligió la VF, p 0,0026 OR 0,31 (IC 95% 0,12 -0,75). 5,2% presentaron complicaciones, no hubo mortalidad relacionada al procedimiento. Conclusiones: La inserción de CVC guiados por US fue segura y significativamente exitosa en el primer intento cuando el vaso de elección fue la VYI, especialmente en < 6 meses (AU)


IIntroduction: Central venous catheterization is a common procedure in intensive care units (ICU). The use of ultrasound (US) to guide catheterization offers advantages, allowing for an accurate topographic image of the vessel, reducing complications as well as time and number of punctures. Objective: To determine whether the use of US for the placement of central venous catheters (CVCs) may decrease the number of punctures and achieve successful catheterization. Patients and methods: A descriptive, prospective study was conducted of CVCs placed by US-guided puncture at a general ICU of Hospital de Pediatría Juan P. Garrahan between 2018 and 2019. Patients from 1 month to 18 years of age who required US-guided placement of a CVC were included. A p< 0.05 was considered significant. Results: The internal jugular vein (IJV) was used in 66 (43.5%) and the femoral vein (FV) in 86 patients (56.5%). Overall, in 86 (56.5%) CVC were inserted on the first attempt and 66 (43.5%) required more than one attempt. Insertions into the VYI were successful on the first attempt in 46 (53.5%) patients and 20 (30.3%) patients required more than one attempt, p 0.004; OR 0.37 (95% CI 0.18-0.78). In patients <6 months CVCs placed in the IJV had a lower risk of requiring more than one attempt compared to those in which the FV was chosen, p 0.0026 OR 0.31 (95% CI 0.12 -0.75). Complications occurred in 5.2%; no procedure-related mortality was observed. Conclusions: US-guided insertion of CVC was safe and significantly successful on the first attempt when the vessel of choice was the IJV, especially in patients < 6 months (AU)

ABSTRACT

Abstract Background and objectives Ultrasound-guided internal jugular vein catheterization is a common and generally safe procedure in the operating room. However, inadvertent puncture of a noncompressible artery such as the subclavian artery, though rare, may be associated with life-threatening sequelae, including hemomediastinum, hemothorax, and pseudoaneurysm. Case report We describe a case of the successful endovascular repair of right subclavian artery injury in a 75-year-old woman. Subclavian artery was injured secondary to ultrasound-guided right internal jugular vein catheterization under general anesthesia for orthopedic surgery. Conclusion Under general anesthesia several factors such as hypotension can mask the signs of subclavian artery injury. This case report indicates that clinicians should be aware of the complications of central venous catheterization and take prompt action.


Resumo Justificativa e objetivos A cateterização da veia jugular interna guiada por ultrassom é um procedimento comum e geralmente seguro em sala cirúrgica. No entanto, a punção inadvertida de uma artéria não compressível, como a artéria subclávia, embora rara, pode estar associada a sequelas e risco para vida, incluindo hemomediastino, hemotórax e pseudoaneurisma. Relato de caso Descrevemos um caso bem-sucedido da correção endovascular de lesão da artéria subclávia direita em uma paciente de 75 anos. A artéria subclávia foi lesionada após cateterização guiada por ultrassom da veia jugular interna direita sob anestesia geral para cirurgia ortopédica. Conclusão Sob anestesia geral, vários fatores, como a hipotensão, podem mascarar os sinais de lesão da artéria subclávia. Este relato de caso indica que os médicos devem estar cientes das complicações da cateterização venosa central e tomar medidas imediatas.

ABSTRACT

ABSTRACT Objective: To evaluate the compliance of the care process involving insertion of central vascular catheter (CVC) in hemodialysis. Method: Cross-sectional quantitative approach developed at the hemodialysis service of a reference hospital in Sergipe, Brazil. Sample consisting of 1,342 actions evaluated, corresponding to 122 forms for monitoring and control of CVC insertion. Data collection was held from July to December 2016. Results: The adherence rate to the use of the insertion form was 54.9%. The procedure evaluated achieved 93% overall compliance. Of the 11 specific actions observed, seven (64%) presented 100% compliance. The density of the overall incidence of primary bloodstream infections reduced from 10.6 to 3.1 infections per 1,000 patients/day. Conclusion: Although the observed actions reached specific desired conformities, the use of the checklist was lower than expected. Strategies for monitoring, coaching and educational and organizational actions can contribute to safe care.

ABSTRACT

Background: Placing central venous lines under ultrasonographic guidance reduces the complications of the procedure. Aim: To compare prevalences of complications of central venous line placements with or without ultrasonographic guidance. Material and Methods: Descriptive study that contemplated the comparison of two groups of patients subjected to a central venous line placement at a nephrology service for renal replacement therapy. In one group of 100 patients, the line was placed without ultrasonographic guidance between 2008 and 2012. Between 2015 and 2017 the line was placed in 138 patients using ultrasonographic guidance. The prevalences of complications with both types of procedures were recorded. Results: The frequency of complications of procedures with and without ultrasonographic guidance was 0.7 and 18% respectively (prevalence ratio 0.04, 95% confidence interval 0-0.3). Ninety five percent of recorded complications were arterial puncture, followed by hematomas in 10% and pneumothorax in 5%. The higher prevalence of complications was observed in emergency line placement without ultrasonographic guidance. There was a direct association between the number of line placement attempts in a single procedure and the prevalence of complications. Conclusions: Ultrasonographic guidance is associated with a reduction in the prevalence of central venous line complications.

ABSTRACT

Representantes de la Sociedad Argentina de Infectología (SADI) y la Sociedad Argentina de Terapia Intensiva (SATI) se reunieron para trabajar en la elaboración de recomendaciones concretas de diagnóstico, tratamiento y prevención de las infecciones asociadas a catéteres venosos centrales (IAC). La metodología utilizada fue el análisis de la bibliografía publicada en los últimos 10 años complementada con la opinión de expertos y datos locales. En este documento se pretende ofrecer herramientas básicas de optimización de diagnóstico sobre la base de criterios clínicos y microbiológicos, orientar acerca de los esquemas antibióticos empíricos y dirigidos, la posología y la administración de antibióticos en pacientes críticos, y promover las medidas efectivas para reducir el riesgo de IAC. Asimismo, se ofrece un algoritmo de diagnóstico y tratamiento para uso en la actividad asistencial y consideraciones sobre la dosificación de antibióticos. Este trabajo conjunto de infectólogos e intensivistas pone en evidencia la preocupación por el manejo de las IAC y la importancia de velar por la mejora en las prácticas cotidianas. A través de esta recomendación se establecen pautas locales para optimizar el diagnóstico, el tratamiento y la prevención de las IAC con el objeto de disminuir la morbimortalidad, los días de internación, los costos y la resistencia antimicrobiana.


Representatives of the Argentine Society of Infectious Diseases (SADI) and the Argentine Society of Intensive Therapy (SATI) joined together to issue specific recommendations for the diagnosis, treatment, and prevention of intravascular catheter related infections (CRI). The methodology used was the analysis of the literature published in the last 10 years, complemented with the opinion of experts and local data. This document aims to promote effective measures to reduce the risk of CRI and to offer basic tools for diagnosis optimization based on clinical and microbiological criteria, orientation on empirical and targeted antibiotic schemes, posology, and administration of antibiotics in critical patients. It also offers a diagnostic and treatment algorithm for use in the care activity, as well as considerations on the dosage of antibiotics. The joint work of both societies highlights the concern for the management of CRI and the importance of ensuring improvement in daily practices. Through this recommendation, local guidelines are established to optimize the diagnosis, treatment and prevention of CRI in order to reduce morbidity and mortality, days of hospitalization, costs, and antimicrobial resistance.

ABSTRACT

RESUMO Objetivo: Determinar os fatores de risco para contrair infecções da corrente sanguínea associadas a cateter de acesso central em unidades de terapia intensiva pediátrica, e investigar a incidência e a etiologia dessas infecções nas unidades de terapia intensiva pediátrica com diferentes perfis. Métodos: Este foi um estudo prospectivo de coorte, conduzido em três hospitais. Um deles é um grande hospital público metropolitano, com duas unidades de terapia intensiva pediátrica que contabilizam 19 leitos; o segundo é um hospital regional com oito leitos em unidade de terapia intensiva pediátrica; e o terceiro é um hospital privado com 15 leitos de terapia intensiva pediátrica. Incluíram-se pacientes com idades entre 1 mês e 18 anos, que utilizaram cateter de acesso venoso central por pelo menos 24 horas. Registramos a evolução diária dos pacientes. Colheram-se dados gerais sobre o paciente e sobre o cateter, utilizados como variáveis. Todos os dados foram analisados com utilização do pacote estatístico Statistical Package for Social Science (SPSS), versão 13.0, para comparação de pacientes com infecção da corrente sanguínea associada a cateter com ou sem fatores de risco. Resultados: Durante o período do estudo admitiram-se às unidades de terapia intensiva 728 pacientes; deles, 170 tiveram cateter de acesso venoso central instalado por, no mínimo, 24 horas. A mediana de idade foi de 32 meses, e 97 (57%) dos pacientes eram do sexo masculino. A taxa de incidência de infecções da corrente sanguínea relacionadas a cateter foi de 3,9/1.000 cateteres venosos centrais-dias. A incidência variou entre os hospitais, sendo de 1,6 a 6,6. A taxa geral de mortalidade foi de 11,1%, e as taxas de mortalidade com e sem infecções da corrente sanguínea relacionadas a cateter foram, respectivamente, de 12,9% e 10,7%. Na análise multivariada, os fatores de risco para ocorrência de infecções da corrente sanguínea relacionadas a cateter foram maior tempo de uso do cateter venoso central (OR: 1,07; IC95% 1,00 - 1,14; p = 0,019) e o uso de mais de um cateter venoso central de uma vez (OR: 2,59; IC95% 1,17 - 5,73; p = 0,048). Conclusão: Maior duração do uso de cateter venoso central e mais de um cateter venoso central de uma vez foram os principais fatores de risco para infecções da corrente sanguínea associadas a cateter em unidades de terapia intensiva pediátrica.


ABSTRACT Objectives: To determine the risk factors for acquiring central line-associated blood stream infections (CLABSI) in pediatric intensive care units and to investigate the incidence and etiology of CLABSI in pediatric intensive care units with different profiles. Methods: The study was a prospective cohort study in three hospitals. One of the hospitals is a large metropolitan public hospital with two pediatric intensive care units and a total of nineteen pediatric intensive care unit beds, another is a regional hospital with eight pediatric intensive care unit beds, and the third is a private hospital with fifteen beds. Patients between the ages of 1 month old and 18 years old who used a central venous catheter for over 24 hours were included. We recorded patients' daily progress. General patient and catheter-related data were collected and used as variables. All the data were analyzed using Statistical Package for Social Science (SPSS), version 13.0, to compare patients with CLABSI with or without risk factors. Results: A total of 728 patients were admitted to the pediatric intensive care units, and 170 had a central line in place for at least 24 hours. The median age was 32 months, and 97 (57%) of the patients were males. The CLABSI incidence rate was 3.9/1000 central venous catheter-days. The incidence among hospitals varied from 1.6 to 6.6. The overall mortality rate was 11.1%, and the CLABSI and non-CLABSI mortality rates were 12.9% and 10.7%, respectively. In multivariate analysis, independent risk factors for CLABSI were a longer duration of central venous catheter use (OR: 1.07; 95%CI 1.00 - 1.14; p = 0.019) and the use of more than one central venous catheter at once (OR: 2.59; 95%CI 1.17 - 5.73; p = 0.048). Conclusion: A longer duration of central venous catheter use and the use of more than one central venous catheter at once were the main risk factors for CLABSI in pediatric intensive care units.

ABSTRACT

ABSTRACT Background: The impact of central venous catheter (CVC) removal on the outcome of patients with candidemia is controversial, with studies reporting discrepant results depending on the time of CVC removal (early or any time during the course of candidemia). Objective: Evaluate the effect of time to CVC removal, early (within 48 h from the diagnosis of candidemia) vs. removal at any time during the course of candidemia, on the 30-day mortality. Methods: Retrospective cohort study of 285 patients with candidemia analyzing CVC removal within 48 h (first analysis) or at any time (second analysis). Results: A CVC was in place in 212 patients and was removed in 148 (69.8%), either early (88 patients, 41.5%) or late (60 patients, 28.3%). Overall, the median time to CVC removal was one day (range 1-28) but was six days (range 3-28) for those removed later. In the first analysis, APACHE II score (odds ratio [OR] 1.111, 95% confidence interval [95% CI] 1.066-1.158), removal at any time (OR 0.079, 95% CI 0.021-0.298) and Candida parapsilosis infection (OR 0.291, 95% CI 0.133-0.638) were predictors of 30-day mortality. Early removal was not significant. In the second analysis APACHE II score (OR 1.122, 95% CI 1.071-1.175) and C. parapsilosis infection (OR 0.247, 95% CI 0.103-0.590) retained significance. Conclusions: The impact of CVC removal is dependent on whether the optimal analysis strategy is deployed and should be taken into consideration in future analyses.

ABSTRACT

Introducción. La canalización vascular central en niños presenta alta complejidad técnica y dificultades. La ecografía vascular puede facilitar este procedimiento. Objetivo. Describir las características de las canalizaciones vasculares ecoguiadas en el paciente pediátrico crítico. Población y métodos. Las variables de interés registradas prospectivamente fueron los vasos más comúnmente canalizados, su localización, la medición del diámetro/profundidad, la tasa de éxito y las complicaciones presentadas, entre otras. Resultados. En 86 pacientes pediátricos, se realizaron 124 punciones vasculares. Los accesos vasculares fueron la vena femoral (39,7%), seguida de la arteria femoral (27,2%) y la vena yugular interna (14,7%). Los vasos femorales se localizaron a una profundidad de 0,75 ± 0,25 mm con un diámetro medio de 0,31 ± 0,16 mm. La profundidad de los vasos venosos yugulares fue menor (0,64 ± 0,24 mm) y su diámetro global, mayor (0,44 ± 0,19 mm). El número medio de intentos en las canalizaciones vasculares ecoguiadas fue de 2,2 ± 1,3. La tasa de éxito fue del 79% asociada a un mayor diámetro del vaso (0,39 ± 0,20 mm vs. 0,28 ± 0,13 mm, p 0,01) y un menor número de intentos (1,90 ± 1,16 vs. 3,45 ± 1,77, p= 0,001). Las complicaciones, fueron la punción accidental de otro vaso (5,3%) y el desarrollo de un hematoma durante la punción (2,3%). Conclusiones. La canalización vascular ecoguiada en los pacientes pediátricos estudiados permite visualizar los vasos y medir su profundidad y diámetro; presenta una alta tasa de éxito y se asocia a una baja tasa de complicaciones.


Introduction. Central vascular cannulation in children is a highly complex technique and poses many difficulties. Vascular ultrasound can make this procedure easier. Objective. To describe the characteristics of ultrasound-guided vascular cannulation in critically-ill pediatric patients. Population and methods. Outcome measures prospectively recorded were vessels most frequently cannulated, their localization, the measurement of their diameter/depth, the success rate and complications developed, among others. Results. One hundred and twenty four vascular punctures were performed in 86 pediatric patients. Vascular accesses were the femoral vein (39.7%), followed by the femoral artery (27.2%) and the internal jugular vein (14.7%). Femoral vessels were localized at a depth of 0.75 ± 0.25 mm, with a mean diameter of 0.31 ± 0.16 mm. The depth of jugular vein vessels was smaller (0.64 ± 0.24 mm) and their overall diameter, larger (0.44 ± 0.19 mm). The mean number of attempts in ultrasound-guided cannulations was 2.2 ± 1.3. The success rate was 79% and was associated to a larger vessel diameter (0.39 ± 0.20 mm vs. 0.28 ± 0.13 mm, p= 0.01) and a lower number of attempts (1.90 ± 1.16 vs. 3.45 ± 1.77, p= 0.001). Complications were accidental puncture of another vessel (5.3%) and hematoma formation during puncture (2.3%). Conclusions. In the pediatric patients studied, ultrasound-guided vascular cannulation allowed vessel visualization and measurement of their depth and diameter; the success rate was high and it was associated to a low complication rate.

ABSTRACT

Abstract Objective: This was a systematic review of the incidence density and risk factors for central venous catheter-related infections in a neonatal population. Data source: The MEDLINE, Embase, Cochrane, BDENF, SciELO, and LILACS databases were used without date or language restriction. Studies that analyzed risk factors for bloodstream infections in newborns were identified. Data synthesis: A total of 134 articles were found that met the eligibility criteria. Of these articles, 14 were selected that addressed risk factors for central venous catheter-related infection in neonates. Catheter-related bloodstream infections remain an important complication, as shown by the incidence rates reported in the studies included in this review. The observed risk factors indicate that low birth weight, prematurity, and longer catheter permanence are related to a higher incidence of bloodstream infections. It has been observed that low rates of catheter-related infections, i.e., close to zero, are already a reality in health institutions in developed countries, since they use infection surveillance and control programs. Conclusion: Catheter-related bloodstream infections still show high incidence density rates in developing countries. The authors emphasize the need for further longitudinal studies and the need for better strategies to prevent risk factors, aiming at the reduction of catheter-related infections.


Resumo Objetivo: Revisão sistemática sobre a densidade de incidência e de fatores de risco para infecção associada a cateter venoso central em população neonatal. Fontes dos dados: Usaram-se os bancos de dados Medline, Embase, Cochrane, Bdenf, Scielo e Lilacs, sem restrição de data ou de idioma. Identificaram-se os estudos que analisaram fatores de risco para infecção da corrente sanguínea em recém-nascidos. Síntese dos dados: Foram encontrados 134 artigos conforme os critérios de elegibilidade. Desses, foram selecionados 14 que abordaram fatores de risco para infecção associada a cateter venoso central em neonatos. A infecção da corrente sanguínea associada a cateter continua a mostrar-se como uma importante complicação, conforme demonstram as taxas de incidência relatadas nos estudos incluídos nesta revisão. Os fatores de risco observados apontam que baixo peso ao nascer, prematuridade e maior tempo de permanência do cateter estão relacionados a maior incidência de infecção da corrente sanguínea. Observou-se que taxas de infecção associada a cateter em valores baixos, próximos a zero, já são uma realidade em instituições de saúde de países desenvolvidos, uma vez que usam programas de vigilância e controle de infecção. Conclusão: A infecção da corrente sanguínea associada a cateter ainda apresenta altas taxas de densidade de incidência em países em desenvolvimento. Destaca-se a necessidade de mais estudos longitudinais e a necessidade de melhores estratégias de prevenção dos fatores de risco para a redução de infecção associada a cateter.

ABSTRACT

Introdução: Os cateteres venosos centrais são dispositivos de saúde importantes para a manutenção das terapias venosas na assistência à saúde, principalmente em unidades de alta complexidade e com pacientes em cuidados intensivos e que requer vigilância. A inserção do CVC é de competência médica, para sua indicação devem-se levar em consideração os possíveis riscos e complicações envolvidos com uso da terapia. Os eventos adversos relacionados ao uso de cateteres venosos centrais têm sido descritas, pois se trata de uma técnica invasiva, e que pode ocasionar malefícios se mal utilizado para os submetidos ao procedimento. Assim, protocolos rígidos de indicação das regras de assepsia e antissepsia, além dos cuidados a manutenção do cateter, são cruciais para se minimizar a probabilidade de complicações. As complicações decorrentes do uso do cateter venoso central se dividem em complicações locais e sistêmicas dentre elas estão: Infiltração, Extravazamento, Flebite, Obstrução, Trombose, Infecção, Hipertermia, Embolia, Pneumotórax, Hemotórax e até mesmo a morte. Objetivo: Analisar os eventos adversos em pacientes portadores de Cateter Venoso Central. Método: O estudo tem caráter retrospectivo, documental, com método quantitativo de análise dos dados. Realizado em um Hospital Público Federal, na cidade de Belo Horizonte. Os dados foram coletados nos meses de junho e julho de 2017, pelo pesquisador, de dados secundários do livro de registros dos procedimentos cirúrgicos do CC em busca de todos os pacientes que foram submetidos ao cateterismo venoso central, no período de setembro de 2016 à novembro de 2016, e de seu respectivos prontuários. A amostra foi composta por 60 prontuários de pacientes. Resultados: Os resultados foram descritos com a caracterização sociodemográficas e clínicas dos pacientes, eventos adversos relacionados ao paciente e ao CVC, fatores que influenciam na ocorrência da urgência na implantação do CVC e fatores que influenciam na ocorrência da 11 hipertermia. Como resultado obteve: Indivíduos do sexo masculino o total de 36 (60,00%), com idade média igual a 23,04 anos, com um desvio padrão de 25,46, A maior parte dos pacientes 50 (83,33%) apresentaram urgência na implantação do cateter, realizaram anestesia local no momento da inserção 24 (40,00%), os grupos com maiores frequências foram ASA II e ASA III com 23 (39,66%), o tipo de cateter mais utilizado foi o Cateter Hemodiálise/Permicath com 22 (36,67%), referente ao tempo de permanência do cateter 30 (50,00%) apresentaram um tempo entre 1 e 10 dias, dos 27 (45,00%) dos pacientes tiveram como local da inserção a veia jugular, tipo de precaução apresentada pelos indivíduos foi a precaução padrão com 46 (76,67%), das complicações analisadas, as que mais predominaram foram infecção do cateter e oclusão com 3 (5,00%), e os sinal mais frequente na inserção do cateter apresenta o sangramento com 11 (18,33%) porém o maior número de pacientes não apresentaram nenhuma intercorrência na inserção do cateter 49 (81,67%), a grande maioria dos pacientes não apresentaram hipertemia 42 (70,00%) e a comorbidade mais frequente foi doença renal ou trato urinário com 28 (46,67%). Conclusão: Os eventos encontrados evidenciam grande relação com as técnicas utilizadas na inserção, os cuidados e na utilização e manutenção dos cateteres. Assim, é necessário criar uma equipe de monitoramento dos EA por meio da aplicação de indicadores de qualidade com o propósito de beneficiar na melhoria da segurança e assistência prestada ao paciente, partindo de um olhar crítico aos problemas para atuar em busca de soluções que proporcionem melhorias para a prática clínica e que fortaleçam a segurança do paciente.(AU)


Introduction: The central venous catheters are important health devices for the maintenance of venous therapies in health care, especially in high complexity units and in intensive care patients who need surveillance. The insertion of CVC is of medical competence, for its indication one must take into account the possible risks and complications involved with the use of the therapy. Adverse events related to the use of central venous catheters are studying due to invasive technique, which can cause harm and if poorly used for those submitted to the procedure. Thus, rigid protocols to indicate the rules of asepsis and antisepsis, as well as catheter maintenance, are crucial to minimize the likelihood of complications. Central venous catheter complications can be local and systemic among them are infiltration, extravasation, phlebitis, obstruction, thrombosis, infection, hyperthermia, embolism, pneumothorax, hemothorax and even death. Objective: The objective is analyze the adverse events in patients with Central Venous Catheter. Method: This study is a retrospective document, with a quantitative method of data analysis. The information was collet in the Federal Public Hospital placed on Belo Horizonte, in the period of June and July of 2017 by the researcher, using secondary data from the records book of the surgical procedures of the Surgical Center. In this moment, the researcher sought all patients who underwent central venous catheterization from September 2016 to November 2016 and from their respective medical records. The sample consisted of 60 patient files. Results: The results were described with the sociodemographic and clinical characterization of the patients, adverse events related to the patient and the CVC, factors that influence the occurrence of urgency in the implantation of CVC and factors that influence the occurrence of hyperthermia. As results obtained: Male subjects are 36 (60.00%), with a mean age of 23.04 years, with a standard deviation of 25.46, most patients 50 (83.33%), (40.00%), the groups with 13 the highest frequencies were ASA II and ASA III with 23 (39.66%), the type of catheter most used was the Hemodialysis / Permicath Catheter with 22 (36.67%). When we analyzed the time of permanence of the catheter 30 (50.00%) presented a time between 1 and 10 days. Twenty-seven patients (45.00%) had a jugular vein at the site of insertion, and 46 (76.67%) of the type of precaution presented by the subjects was the standard precaution. Of the complications analyzed, the most prevalent were catheter infection and occlusion with 3 (5.00%), and the most frequent signs at catheter insertion present bleeding with 11 (18.33%). But the largest number of patients (81.67%), the vast majority of the patients did not present hypertemia 42 (70.00%) and the most frequent comorbidity was renal or urinary tract disease with 28 (46.67%). Conclusion: The events found evidenced a great relation with the techniques used in the insertion, the care, in the way of using the catheters and maintenance of the catheters. Thus, it is necessary to create a monitoring team of the adverse effects that uses through the application of quality indicators with the purpose of benefiting in the improvement of the safety and assistance provided to the patient. For this, it is necessary that the professional takes a critical look at the patient's problems to work in search of solutions that provide improvements in clinical practice and that strengthen patient safety.(AU) I

ABSTRACT

Abstract INTRODUCTION: Bloodstream infections are the second most common cause of death among patients on hemodialysis. This study aimed to evaluate the incidence of and risk factors associated with central venous catheter-related infections in patients undergoing hemodialysis, and to identify and characterize the type and antimicrobial susceptibility profiles of the primary microorganisms isolated during one year of follow-up. METHODS: A prospective cohort study was conducted in 2014 in a hemodialysis referral center. We included 200 outpatients with acute kidney injury who had no permanent venous access. A nurse assessed the patients for signs of infection three times per week during dressing changes. The clinicopathologic characteristics of patients with and without local or systemic infection were compared. RESULTS: Fifty-five episodes of catheter-related infections occurred in 43 (22%) patients; 38 (69%) were bloodstream infections and 17 (31%) were local infections. Thirty-two (75%) patients with infection had femoral vein catheter placement. In total, 6,240 hemodialysis sessions were performed; the rates of primary bloodstream and local infection were 6.1 and 2.7 episodes per 1,000 patients on daily dialysis, respectively. In the univariate analysis, diabetes was significantly associated with the development of infection, while level of education, ethnicity, age, and sex were not. Gram-negative bacteria were primarily isolated from blood culture specimens (55% of samples). Of the Gram-negative isolates, 56% were resistant to the carbapenems. CONCLUSIONS: We identified a high incidence of catheter-related infections caused by resistant microorganisms in patients undergoing hemodialysis via central venous catheters.

ABSTRACT

Abstract Purpose: To compare the fixation of the central venous catheter (CVC) using two suture techniques. Methods: A clinical, analytical, interventional, longitudinal, prospective, controlled, single-blind and randomized study in adult, intensive care unit (ICU) patients. After admission and indication of CVC use, the patients were allocated to the Wing group (n = 35, catheter fixation with clamping wings and retainers) or Shoelace group (n = 35, catheter fixation using shoelace cross-tied sutures around the device). Displacement, kinking, fixation failure, hyperemia at the insertion site, purulent secretion, loss of the device, psychomotor agitation, mental confusion, and bacterial growth at the insertion site were evaluated. Results: Compared with the Wing group, the Shoelace group had a lower occurrence of catheter displacement (n=0 versus n =4; p = 0.04), kinking (n=0 versus n=8; p=0.001), and fixation failure (n=2 versus n=8; p=0.018). No significant difference was found in bacterial growth (n=20 versus n=14; p=0.267) between groups. Conclusion: The Shoelace fixation technique presented fewer adverse events than the Wing fixation technique.

ABSTRACT

Summary Introduction: Central venous catheters are fundamental to daily clinical practice. This procedure is mainly performed by residents, often without supervision or structured training. Objective: To describe the characteristics of central venous catheterization and the complication rate related to it. Method: Retrospective cohort study. Adult patients undergoing central venous catheter insertion out of the intensive care unit (ICU) of a teaching hospital were selected from March 2014 to February 2015. Data were collected from medical charts using an electronic form. Clinical and laboratory characteristics from patients, procedure characteristics, and mechanical and infectious complications rates were assessed. Patients with and without complications were compared. Results: Three hundred and eleven (311) central venous catheterizations were evaluated. The main reasons to perform the procedure were lack of peripheral access, chemotherapy and sepsis. There were 20 mechanical complications (6% of procedures). Arterial puncture was the most common. Procedures performed in the second semester were associated with lower risk of complications (odds ratio 0.35 [95CI 0.12-0.98; p=0.037]). Thirty-five (35) catheter-related infection cases (11.1%) were reported. They were related to younger patients and procedures performed by residents with more than one year of training. Procedures performed after the first trimester had a lower chance of infection. Conclusion: These results show that the rate of mechanical complications of central venous puncture in our hospital is similar to the literature, but more attention should be given to infection prevention measures.


Resumo Introdução: Cateteres venosos centrais são fundamentais na prática clínica diária. Em hospitais de ensino, esse procedimento é realizado por médicos residentes, frequentemente sem supervisão ou treinamento estruturado. Objetivo: Descrever as características das punções venosas centrais e a taxa de complicações relacionadas. Método: Estudo de coorte retrospectiva. Foram selecionados pacientes adultos submetidos a punção venosa central fora de unidade de terapia intensiva (UTI) de um hospital de ensino no ano letivo de 2014 (março de 2014 a fevereiro de 2015). Os dados foram coletados por meio de revisão de prontuários com o uso de formulário eletrônico. Foram avaliadas características clínicas e laboratoriais dos pacientes, características do procedimento, taxa de complicações mecânicas e infecciosas relacionadas. Foram comparados os pacientes com complicações em relação àqueles sem complicações. Resultados: Foram avaliadas 311 punções venosas centrais. Os principais motivos para realização do procedimento foram falta de rede periférica, quimioterapia e sepse. Ocorreram 20 complicações mecânicas (6% dos procedimentos); punção arterial foi a mais comum. Procedimentos realizados no segundo semestre do ano letivo foram associados a menor risco de complicações (razão de chances de 0,35 [IC95 0,12-0,98; p=0,037]). Foram descritos 35 casos de infecção relacionada ao cateter (11,1%). Casos de infecção foram associados a pacientes mais jovens e procedimentos realizados por residentes com mais de um ano de treinamento. Procedimentos realizados após o primeiro trimestre tiveram menor chance de infecção. Conclusão: Esses resultados mostram que a taxa de complicações mecânicas de punção venosa central em nosso hospital é semelhante à da literatura; porém, maior atenção deve ser dada para medidas de prevenção de infecção.

ABSTRACT

Background: Infectious complications associated to central venous catheter (CVC) increase morbidity, mortality and costs. Total parenteral nutrition (TPN) is one of the risk factors described for catheter-related bloodstream infection (CR-BSI). The aim of this study was explore if TPN and time of exposition, are risk factors for CR-BSI among patient exposed to this therapy. Patients and Methods: Cohort study of patients with CVC exposed and not exposed to TPN with calculation of the relative risk (RR) for CR-BSI and percentage of CR-BSI according to different times of exposition to TPN. Study encompassed years 2010-2015 and only adult patients were included. Results: During the study period 51 events of CR-BSI were identified, with 27 occurring among those exposed to TPN and 24 among those not exposed. CR-BSI incidence rate was 6.3 in the group with TPN and 1.2 in those without this therapy (RR 5.4; IC 95 3.6-8.2). The percentage of patients with CR-BSI increased in parallel to exposition time (Pearson coefficient +0.91) and the OR increased for expositions ≥ 7 days (OR 2.8; IC 95 1.047.4; p < 0.05). Conclusions: Exposition to TPN increases the risk to CR-BSI in adult patients with CVC and this risk raise with exposition time.


Antecedentes: Las complicaciones infecciosas asociadas a dispositivos vasculares centrales tienen impacto en morbi-mortalidad y costos. Diferentes factores de riesgo han sido identificados en las ITS/CVC, incluyendo la nutrición parenteral total (NPT). Objetivo: Determinar si la NPT y el tiempo de exposición constituyen factores de riesgo para desarrollar ITS/CVC. Pacientes y Método: Estudio de cohortes de diseño prospectivo, de pacientes adultos con catéter venoso central (CVC) convencional, internados en el Hospital Militar entre los años 2010 y 2015 y que estuvieron expuestos o no expuestos a NPT, calculando el riesgo relativo (RR) y la distribución porcentual de las ITS/CVC a diferentes intervalos de exposición de NPT con análisis de coeficiente de correlación y cálculo de Odds Ratio (OR). Resultados: Durante el período de estudio se registraron 51 eventos de ITS/CVC en pacientes adultos con CVC, de los cuales 27 estuvieron expuestos a NPT y 24 no. Incidencia de 6,3 por 1.000 días en expuestos a NPT vs 1,2 en no expuestos (RR de 5,4; IC 95 3,6 a 8,2). La proporción de pacientes con ITS/CVC aumentó a medida que aumentaba la exposición a NPT (coeficiente correlación r = +0,91), siendo significativa para exposiciones ≥ 7 días (OR 2,8; IC 95 1,04-7,4; p < 0,05). Conclusiones: La exposición a NPT aumenta el riesgo de ITS/CVC en pacientes adultos hospitalizados respecto a aquellos pacientes que no reciben NPT, además este riesgo aumenta con el tiempo de exposición.

ABSTRACT

RESUMO Objetivo: Identificar e avaliar o posicionamento correto dos dispositivos médicos mais comumente utilizados, observados nas radiografias de tórax de pacientes durante a permanência em unidade de terapia intensiva de nosso centro. Métodos: Foi realizada uma pesquisa bibliográfica quanto aos critérios utilizados para avaliar o posicionamento correto dos dispositivos médicos nas radiografias de tórax. Avaliamos todas as radiografias de tórax realizadas na unidade de terapia intensiva de nosso centro durante um período de 18 meses. Incluíram-se todas as admissões nas quais foi realizada uma radiografia do tórax na unidade de terapia intensiva, nas quais fosse identificável a presença de pelo menos um dispositivo médico. Para análise, selecionou-se uma radiografia por admissão. As radiografias foram avaliadas por um observador independente. Resultados: De um total de 2.312 radiografias analisadas, 568 foram incluídas neste estudo. Identificaram-se diversos dispositivos médicos, incluindo eletrodos de monitoramento, tubos endotraqueais, cânulas de traqueostomia, cateteres venosos centrais, marca-passos e próteses valvares cardíacas. Dentre os cateteres venosos centrais identificados, 33,6% dos subclávios e 23,8% dos jugulares estavam mal posicionados. Dentre os tubos endotraqueais, 19,9% estavam mal posicionados, enquanto todas as cânulas de traqueostomia tinham posicionamento correto. Conclusão: Frequentemente se identificam, na radiografia de tórax realizada em pacientes na unidade de terapia intensiva, cateteres venosos e tubos endotraqueais mal posicionados. Isso é importante, pois dispositivos mal posicionados podem se relacionar a eventos adversos. Estudos futuros devem investigar possíveis associações entre o mau posicionamento dos dispositivos e eventos adversos.


ABSTRACT Objective: To identify and evaluate the correct positioning of the most commonly used medical devices as visualized in thoracic radiograms of patients in the intensive care unit of our center. Methods: A literature search was conducted for the criteria used to evaluate the correct positioning of medical devices on thoracic radiograms. All the thoracic radiograms performed in the intensive care unit of our center over an 18-month period were analyzed. All admissions in which at least one thoracic radiogram was performed in the intensive care unit and in which at least one medical device was identifiable in the thoracic radiogram were included. One radiogram per admission was selected for analysis. The radiograms were evaluated by an independent observer. Results: Out of the 2,312 thoracic radiograms analyzed, 568 were included in this study. Several medical devices were identified, including monitoring leads, endotracheal and tracheostomy tubes, central venous catheters, pacemakers and prosthetic cardiac valves. Of the central venous catheters that were identified, 33.6% of the subclavian and 23.8% of the jugular were malpositioned. Of the endotracheal tubes, 19.9% were malpositioned, while all the tracheostomy tubes were correctly positioned. Conclusion: Malpositioning of central venous catheters and endotracheal tubes is frequently identified in radiograms of patients in an intensive care unit. This is relevant because malpositioned devices may be related to adverse events. In future studies, an association between malpositioning and adverse events should be investigated.

ABSTRACT

We present two cases of misplaced central venous catheters having in common theabsence of free blood return from one lumen immediately after placement. The former is acase of right hydrothorax associated with central venous catheterization with the catheter tipin intra-pleural location. In this case the distal port was never patent. In the latter case therewas an increased aspiration pressure through the middle port due to a catheter looping.The absence of free flow on aspiration from one lumen of a central catheter should not beundervalued. In these circumstances the catheter should not be used and needs to be removed.


Apresentamos dois casos de mau posicionamento de cateter venoso central. Têmem comum a ausência do retorno sanguíneo livre em um dos lúmens imediatamente após acolocac¸ão. O primeiro é um caso de hidrotórax direito associado ao cateterismo venoso central,com a ponta do cateter em localizac¸ão intrapleural. Nesse caso, a porta distal nunca estevepatente. No segundo caso houve um aumento da pressão de aspirac¸ão através da porta medialpor causa da formac¸ão de alc¸a no cateter.A ausência de fluxo livre na aspirac¸ão de um lúmen do cateter central não deve ser subesti-mada. Nessas circunstâncias, o cateter não deve ser usado e deve ser removido.
