“…No entanto, existem dois obstáculos relevantes nessa bomba que são o alto custo desse equipamento e a grande geração de ruídos na linha base da análise devido aos pulsos gerados, de maneira que, novos tipos de equipamentos substituintes da bomba peristáltica têm sido ainda mais desenvolvidos e empregados. 19,29 Uma alternativa viável de substituição das bombas peristálticas foi proposta por Moreira et al em 2014, 19 na qual utilizaram bombas de aquário e alguns outros materiais alternativos, mostrando além de bons resultados, um baixo custo e fácil manuseio de equipamentos. O controle das vazões dos minicompressores de ar utilizados foi feito por meio da variação das pressões obtidas pelas diferentes alturas de colunas de água.…”

During the human development is common have an increase of medications consumption, in especial caused by new disease or complications, both in the health of the humans and animals. This may it turn a social problem because of no frequency on industrial or environmental control. In that context, exist a necessity of efficient methodologies to monitory the biochemistry composition of products or waste generated and in this perspective the electrochemistry has been so much studied. Any important characteristics of the electrochemistry methodologies need be highlight, such as portability, analytical speed, high sensibility and selectivity, besides of good results of detection and quantification of analyte. It can be further explored in terms of better robustness, velocity and analytical frequency when associated, for example, the flow or batch system of injection. Flow Injection Analysis (FIA) is an analytic system where the samples are moved in direction to the detection with a flow of solutions, while the Batch Injection Analysis is a system used to insert the samples mechanically into the work electrode surface, allowed to both successive analysis. These technologies are characterized by low consumption of solution, relative low cost of instrumentation and easy maintenance. Due it, the goal of this work is to do a review about the advantages of the electroanalytical methods when they are used with FIA and BIA system, highlight their assembly and application to detection of drugs. Com o passar do tempo o consumo de medicamentos tem se tornado excessivo, principalmente com o desenvolvimento de novas doenças ou complicações tanto na saúde de humanos como de animais, o que se torna um problema social devido à ausência frequente do controle industrial e ambiental. Nesse sentido, há uma demanda por metodologias eficientes para o monitoramento bioquímico dos produtos e resíduos gerados e, nessa perspectiva, destacam-se os métodos eletroanalíticos, já que estes apresentam portabilidade, rapidez analítica, alta sensibilidade e seletividade, além de bons resultados de limite de detecção e quantificação de vários desses fármacos. Essas metodologias podem ainda ser aprimoradas quanto à robustez, velocidade e frequência analítica por meio, por exemplo, da utilização dos sistemas de injeção em fluxo e em batelada. A Análise por Injeção em Fluxo (FIA) consiste de um sistema analítico no qual as amostras são carregadas e transportadas ao longo do sistema por um fluxo contínuo de soluções em direção ao detector, enquanto que na Análise por Injeção em Batelada (BIA) alíquotas das amostras são injetadas mecanicamente sobre a superfície do eletrodo de trabalho permitindo, em ambas, a realização de análises sucessivas. Estas tecnologias possibilitam então, um baixo consumo de soluções, são de fácil manuseio e manutenção, contando ainda com o custo moderado para a instrumentação necessária. Dessa forma, este trabalho tem como objetivo revisar sobre as vantagens dos métodos eletroanalíticos acoplados aos sistemas FIA e BIA, destacando ...

Precision and reliability study of hospital infusion pumps: a systematic review

et al. 2023

View full text Add to dashboard Cite

Background Infusion Pumps (IP) are medical devices that were developed in the 1960s and generate fluid flow at pressures higher than that of normal blood pressure. Various hospital sectors make use of them, and they have become indispensable in therapies requiring continuity and precision in the administration of medication and/or food. As they are classified Class III (high risk) equipment, their maintenance is crucial for proper performance of the device, as well as patient and operator safety. The principal consideration of the pump is the volume infused, and the device demands great attention to detail when being calibrated. A lack of necessary care with this equipment can lead to uncertainty in volume and precision during the administration of substances. Because of this, it is essential to evaluate its reliability, to prevent possible failures at time of execution. This control aims at the quality of the intended infusion result, becoming an indication of quality. Methods This systematic review summarizes studies done over the last 10 years (2011 to December 2021) that address the reliability and accuracy of hospital infusion pumps, in order to identify planning of maintenance and/or other techniques used in management of the equipment. The Prisma method was applied and the databases utilized were Embase, MEDLINE/Pubmed, Web of Science, Scopus, IEEE Xplore, and Science Direct. In addition, similar reviews were studied in Prospero and the Cochrane Library. For data analysis, softwares such as Mendeley, Excel, RStudio, and VOSviewer were used, and Robvis helped in plotting risk of bias results for studies performed with Cochrane tools. Results The six databases selected produced 824 studies. After applying eligibility criteria (inclusion and exclusion), removing duplicates, and applying filters 1 and 2, 15 studies were included in the present review. It was found that the most relevant sources came from the Institute of Electrical and Electronics Engineers (IEEE) and that the most relevant keywords revolved around the terms (“device failure”, “infusion pumps”, “adverse effects”, “complications”, etc.). These results made clear that there remains substantial room for improvement as it relates to the study of accuracy and reliability of infusion. Conclusions We verified that the reliability and precision analysis of hospital infusion pumps need to be performed in a more detailed and consistent way. New developments, considering the model and IP specification, are intended, clearly explaining the adopted methodology.
