Esta revisão integrativa da literatura teve como objetivo identificar na literatura nacional e internacional, no período de 1992 a 2002, as publicações referentes à utilização de curativos para manutenção de cateter intravenoso periférico. Identificamos sete artigos científicos no banco de dados Medline por meio da utilização dos descritores “peripheral catheterization” e “dressing”. Para o alcance dos objetivos utilizado-se um roteiro sistematizado de coleta de dados. A análise constituiu da categorização, ordenação e síntese dos dados. Os resultados demonstraram que quatro publicações foram obtidas no site de periódicos on line disponibilizado pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, seis foram realizadas por enfermeiros, cinco utilizaram como metodologia o desenho descritivo comparativo. As complicações locais foram as variáveis investigadas na maioria das publicações, dois estudos demonstraram redução na ocorrência de complicações locais durante a utilização do curativo transparente com dispositivo de segurança acoplado. As considerações acerca dos problemas metodológicos identificados nas publicações fizeram concluir que falta base suficiente para subsidiar a seleção do curativo para manutenção de cateter intravenoso periférico. / This whole review of literature has the main goal to identify national and international literature within 1992 and 2002, the used reports were the aids to keep on the venous peripheral catheterization. It was identified 7 scientific reports in Medline data basis using the description “peripheral catheterization” and “dressing”. Reaching the goals it was used a standarded data collection. The outcomes showed that four reports were obtained from internet sites of Journals from Graduation and Personal Studies Coordination, six of them were from nurses, five of them used as methodology a comparative descriptive design . The local complications were the researched varieties in the most reports, two studies showed decreased local complications during the use of transparent aid as a close secure gadget. The considerations about the methodological problem identified in the reports leaded us to conclude that misses enough basis to help a selection from aid to maintenance peripheral intravenous peripheral catheterization.

Magnetic sensors are deployed in many applications such as automotive, consumer electronics, navigation and data storage devices. Their market’s growth is driven by demands of higher performance; primarily to assist in the advancement of the Internet of Things (IoT) and smart systems. Challenging obstacles of miniaturization and power consumptions must be overcome. A leading sensor that has the potential to accelerate the development is the magnetic tunnel junction (MTJ) devices. Corrosion causes catastrophic consequences for industries. Preventive measures could save up to 35% of annual corrosion-related costs. An advanced corrosion sensing technique is developed based on iron nanowires. The iron nanowires are magnets which lose their magnetization when corroded. Their magnetization loss is monitored using sensitive MTJ sensor. Combined, the nanowires and the MTJ sensor realize a highly integrated sensor concept that enables corrosion sensing with an ultra-low power consumption of less than 1 nW, a sensitivity of 0.1 %/min, a response time of 30 minutes and an area of 128 μm2. Surgical tool development is accelerating in the healthcare sector. Cardiac catheterization specifically is a minimally invasive surgery that relies heavily on x-ray imaging and contrast dyes. A flexible tri-axis MTJ sensor is developed to help minimizing the need for x-ray imaging during the procedure. The flexible sensor can bend to a diameter of 500 μm without compromising the performance and can endure over 1000 bending cycles without fatigue. Three flexible sensors are mounted onto the tip of a 3 mm cardiac catheter, realizing a novel sensor-on-tube (SOT) tri-axis sensor concept. The sensor has a high sensitivity of 9 Ω/° and an MR ratio of 29%. It weighs 16 μg only, adds 5 μm to the catheter’s diameter and a total size 300 μm2. The prototype system estimated the heading angle with an RMS error value of 7° and tracked the orientation of the sensor with an acceptable accuracy. However, the sensor has a misalignment issue caused by the manual placement of the sensors. A high precision tool is needed for the assembly, and any further misplacement -within a reasonable margin of error- could be corrected by calibration algorithms.

The peripherally inserted central catheter (PICC) is a catheter that is inserted in a peripheral vein, which get along to the superior or inferior cava vein, getting in a central localization, which promotes more safety and comfort to patients. A trained nurse, according to the Resolution of the Federal Nursing Council n º, inserts this catheter. 258/2001. The general objective of this study was aimed to know nurses‟ perceptions when using the peripherally inserted central catheter on adult patients at a teaching hospital. The specific objectives were: to describe nurses‟ experiences in relation to the using of peripherally inserted central catheter on adult patients; and to identify the facilitating and complicating factors in relation to the use of peripherally inserted central catheter by nurses. The research constituted a qualitative, descriptive and exploratory study. The place of study was the Teaching Hospital of Santa Maria, specifically, at areas of adult patients. Data collection was carried out from May to August of 2015. The participants of study were 18 nurses who had training for peripherally inserted central catheter and worked with adult patients. Data was collected through semistructured interviews, which were recorded via audio and later transcribed. Data was also analyzed through thematic analysis. The ethical aspects according to the Resolution 466 of December 2012 from the National Health Council were respected, and the project approved by the Ethics Research Committee under the number CAAE 40675915.1.0000.5346. from the results, three categories emerged: the trained nurses‟ experience when using the peripherally inserted central catheter on adult patients; aspects that interfere when using peripherally inserted central catheter on adult patients; and the using of peripherally inserted central catheter by trained nurses on adult patients: seeking for autonomy. It was possible to verify that the nurses‟ experience when using this catheter on adult patients is recent and timorous. The interviewers cited as facilitating factors for using the catheter: stimulus from the institution, availability of catheter and the support of medical and nursing teams. On the other hand, the complicating factors were: few trained nurses; lack of divulgation of people that have the training; lack of training of nursing professionals; lack of people and time to insert the catheter; service characteristics, patients‟ profile and type of treatment; venous system of hard access; ultrasound machine missing; being a teaching hospital; lack of knowledge from medical and nursing teams; and the lack of eye of nurses to diagnose the necessity of catheter insertion. The results evidenced that PICC is seen as the last option for venous access for some nurses and physicians, being almost not used due to the lack of knowledge between medical and nursing teams. Thus, the nurse has a fundamental role when seeking to upgrade and update their knowledge on the catheter, having to remember their autonomy in order to amplify the using of PICC on adult patients. For this reason, he/she needs to be proactive, have a critical and reflexive thinking to evaluate the patient as soon as he gets into the Unity for earlier indication for this dispositive and train the team to use the same. / O Cateter Central de Inserção Periférica (PICC) é um cateter inserido em veia periférica que progride até a veia cava superior ou inferior, adquirindo localização central, promovendo maior segurança e conforto aos pacientes. Este cateter é inserido por enfermeiro capacitado, conforme Resolução do Conselho Federal de Enfermagem nº 258/2001. O estudo teve como objetivo geral conhecer as percepções de enfermeiros sobre a utilização do Cateter Central de Inserção Periférica em pacientes adultos em um Hospital Universitário. Os objetivos específicos foram: descrever a experiência dos enfermeiros em relação à utilização do Cateter Central de Inserção Periférica em pacientes adultos e identificar os fatores facilitadores e dificultadores em relação ao uso do Cateter Central de Inserção Periférica pelos enfermeiros. A pesquisa constituiu-se em um estudo qualitativo, descritivo e exploratório. O local de estudo foi o Hospital Universitário de Santa Maria, especificamente, nas áreas que atendiam pacientes adultos. A coleta dos dados ocorreu no período de maio a agosto de 2015. Os participantes do estudo foram 18 enfermeiros que tinham capacitação em inserção do Cateter Central de Inserção Periférica e que atuavam com pacientes adultos. Os dados foram coletados por meio de entrevista semiestruturada, que foram gravadas em áudio e após, transcritas. Os dados foram analisados por meio de análise temática. Foram respeitados todos os aspectos éticos conforme Resolução 466 de Dezembro de 2012 do Conselho Nacional de Saúde, sendo o projeto aprovado por Comitê de Ética em Pesquisa sob o nº CAAE 40675915.1.0000.5346. A partir dos resultados emergiram três categorias: a experiência dos enfermeiros capacitados na utilização do Cateter Central de Inserção Periférica em pacientes adultos; aspectos que interferem na utilização do Cateter Central de Inserção Periférica em pacientes adultos e a utilização do Cateter Central de Inserção Periférica por enfermeiros capacitados em pacientes adultos: em busca de autonomia. Verificou-se que a experiência dos enfermeiros no uso deste cateter em pacientes adultos é recente e tímida. Os entrevistados citaram como fatores facilitadores para utilização deste cateter: estímulo da instituição, disponibilidade do cateter e, o apoio das equipes médica e de enfermagem. Já os fatores dificultadores foram: existência de poucos enfermeiros capacitados; falta de divulgação de quem tem o curso; falta de treinamento da equipe de enfermagem; falta de pessoal e falta de tempo para inserção do cateter; características do serviço, perfil dos pacientes e tipo de tratamento; rede venosa difícil; falta do aparelho de ultrassom; fato de ser um hospital escola; falta de conhecimento das equipes médicas e de enfermagem; e a falta de visão do enfermeiro para diagnosticar a necessidade de inserção do cateter. Os resultados evidenciaram que o PICC é visto como última opção de acesso venoso por alguns enfermeiros e médicos, sendo pouco utilizado devido a falta de conhecimento entre as equipes médica e de enfermagem. Portanto, constatou-se que o enfermeiro tem papel fundamental na busca de aprimoramento e atualização sobre o cateter, devendo valer-se de sua autonomia a fim de ampliar a utilização de PICC em pacientes adultos. Para isso ele precisa ser pró-ativo, ter pensamento crítico e reflexivo para avaliar o paciente logo que ele chega à Unidade para a indicação precoce deste dispositivo, devendo, também, treinar a equipe para utilização do mesmo.

Direct measurement of blood pressure using a fluid-filled catheter and an electromechanical transducer is widely accepted in clinical practice. However, errors associated with the measurement are often not appreciated and these catheter-manometer systems are frequently unable to accurately reproduce applied pressures. To assess the accuracy of catheter-manometer systems used for invasive arterial blood pressure measurements, in vitro and in vivo evaluations were performed. The frequency response (described in terms of damped natural frequency and damping factor) for a variety of cannulae, pressure tubing and stopcocks (and combinations thereof) and their dependence on various parameters (catheter length, lumen diameter, fluid temperature and catheter material) were measured using an hydraulic pressure generator. The design and construction details of the pressure generator are presented. It was found that the damped natural frequency of the catheter-manometer system is directly proportional to lumen diameter of the pressure tubing/catheter. Furthermore, damping factor is inversely related to the damped natural frequency and stiffer catheter material (for identical radius ratios) results in higher damped natural frequency. Catheter length is inversely related to damped natural frequency and the resonant frequency decreases for an increase in fluid operating temperature. It was established that all catheter-manometer systems tested were under-damped (0.15 < β < 0.37) and that the damped natural frequency ranged from 10.5 Hz for 1500 mm to 27.0 Hz for pressure tubing of 300 mm in length. Furthermore, catheter-manometer systems which had pressure tubing in excess of 300 mm in length did not comply with the bandwidth requirements for accurate dynamic blood pressure measurement. For the in vivo assessment of the catheter-manometer system, the blood pressure waveform was analysed in the time and frequency domains. It was established that in 60 percent of the cases, the systolic pressure peak was higher when measured by a narrow bandwidth catheter-manometer system compared to that measured by a wide bandwidth system. Furthermore, values of dp/dt maximum were lower for wide bandwidth catheter-manometer systems than those measured by narrow bandwidth systems for heart rates above 90 beats per minute. In the frequency domain analysis, artifact was sometimes found to occur at frequencies higher than the bandwidth of the catheter-manometer system. This high frequency artifact was found to distort the blood pressure waveform and resulted in false high dp/dt and peak systolic pressures.

The placement of an indwelling urinary catheter (IUC) is a commonly performed clinical procedure which may become challenging for the clinician and painful for the patient. In response to urologic complications attributed to repeated failed IUC insertion attempts by nurses, a difficult urinary catheter (DUC) team program was launched in October 2012. The purpose of the doctoral project was to conduct a quality improvement evaluation of the effectiveness of the DUC team program using retrospective data from May 1, 2013 through May 31, 2017. Benner's novice to expert model was chosen as the theoretical framework to guide the additional training, critical thinking, problem-solving, and skill acquisition necessary for team member inclusion. The practice-focused question for the project answered whether DUC team nurses, through advanced training and demonstrated procedural competence, have been effective with DUC insertions. Sources of evidence included primary and secondary articles in peer-reviewed journals, as well as clinical evidence collected from internal sources. During the project time-line, 463 DUC team consultations were recorded with an insertion success rate of 89.6%. Based on the DUC team concept, additional didactic content and simulation training may be developed for other cognitive and skill-based clinical procedures. The implications for positive social change include improved patient safety and comfort, as well as cost savings for the organization and overall healthcare system.
