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.

An inexpensive and simple method to fabricate intracerebroventricular (i.c.v.) cannulae for rats with readily available material is described here. The procedure is cost effective and quick. The cannulae thus designed are suitable for injecting minute quantities (microliters) of drugs/chemicals interacerebroventricularly for acute or chronic experiments in rats.

En el desarrollo de la radiología intervencionista se pasan por tres periodos: el aprendizaje del método, el de convencimiento a los colegas de la utilidad del procedimiento y el de la utilización masiva. Por problemas económicos, los catéteres de alto costo no pueden ser usados de rutina. En este trabajo se discute nuestra experiencia con la utilización de catéteres de bajo costo como vía alternativa
