RESUMO

Background: Peripheral intravenous catheterization, as well as drug administration through it, represents one of the most performed procedures by the Nursing team and, for that, precautions need to be adopted to offer harm-free care. Objective: To verify the association of Nursing professionals' work shift and training time with proper disinfection of intravenous catheter devices in pediatric units. Methods: A cross-sectional and analytical study conducted between June and August 2021 in three hospitalization units of a Pediatric Hospital. The inclusion criterion was drug administration via peripheral intravenous catheters performed by Nursing professionals. The data were analyzed according to inferential statistics, adopting p ≤ .05 as significance level. Results: There were a total of 385 observations of drug administration procedures. The device was not disinfected in 60.3% of the cases, there was no friction at the suitable time in 86.3%, and the disinfectant was not allowed to dry in 72.5%. The work shift exerted no influence on performance of the disinfection procedure (p = .376). However, longer training time was associated with a lower rate in performing such procedure (p < .001). Conclusion: Performing friction below the recommended time can cause a false sense of prevention of catheter-associated bloodstream infection; therefore, training sessions and strategies for adherence to the disinfection procedures should be considered, mainly for professionals with more training time.

RESUMO

ABSTRACT Objective: to assess the incidence of complications related to peripherally inserted central catheters in hospitalized adult patients with Covid-19 and to discuss the potential benefits of employing insertion technologies to prevent complications. Method: a descriptive, exploratory and cross-sectional study was conducted from March 2020 to December 2021 at a high-complexity hospital. The study included patients over 18 years old with a positive diagnosis for Covid-19 who made use of peripherally inserted central catheters for venous infusion. Data collection included sociodemographic and clinical information regarding catheter insertion and use. The analysis involved Chi-square and Fisher's Exact tests, with a significance level of 0.05. Results: a total of 123 inserted catheters were analyzed. The patients' mean age was 50 years old (SD=16.37), most of them male and in the acute phase of infection (59.3%). The following significant complications related to the insertion process were identified: catheter material (p=0.01); use of Sherlock (p=0.03); need for traction (p<0.001); number of punctures (p<0.001); and difficulty in catheter progression (p<0.001). Conclusion: the study identified the main complications related to the insertion and use of PICCs and showed that employing vascular visualization technologies such as ultrasound and Sherlock 3CG® can mitigate complications, as well as maximize patient comfort, experience and safety. The research provides support for the implementation of protocols for insertion and management of peripherally inserted central catheters, thus avoiding the occurrence of adverse events.

RESUMO

Objective: to analyze the effectiveness of peripherally inserted central catheter insertion techniques in preventing the occurrence of complications related to this device in newborns. Method: a paired and network systematic literature review and meta-analysis, with its search carried out in seven databases and in the Grey Literature, including randomized and non-randomized clinical trials. The risk of bias was assessed using the Cochrane Risk of Bias 2 and Risk of Bias In Non-randomized Studies of Interventions tools. Certainty of the evidence was assessed by means of the Grading of Recommendations Assessment, Development and Evaluation. A meta-analysis was carried out with the aid of the R statistical program. Results: eight studies with 1,126 newborns were included and six insertion techniques were identified: intracavitary electrocardiogram; intracavitary electrocardiogram associated with ultrasound; ultrasound; formula; anatomical landmark; and modified anatomical landmark. Five techniques significantly decreased primary tip malpositioning when compared to the control ( p <0.05). Intracavitary electrocardiogram significantly and more effectively reduced arrhythmias, general complications and phlebitis; the technique that used a formula also reduced general complications. Infection, infiltration, secondary tip malpositioning, catheter rupture, thrombosis, occlusion and catheter-associated skin lesion were not significantly preventable events. Conclusion: intracavitary electrocardiogram and use of the formula were the most effective techniques in reducing complications.

RESUMO

AIM: to compare the effect of rapid cycle deliberate practice simulation training with skill-training simulation on peripheral intravenous catheter insertion for Licensed Practical Nurses. BACKGROUND: The use of peripheral intravenous catheters is associated with high rates of complications, although it is widely used in clinical practice. Training strategies to ensure good performance can minimize the risks inherent to this procedure. DESIGN: A randomized simulation experimental pre-post interventional study. METHODS: Sixty participants were allocated to intervention (n = 30) or control (n = 30) groups. Participants allocated to the intervention group were trained through the Rapid cycle deliberate practice simulation strategy, while participants in the control group were trained through the skill-training simulation strategy. A pre-test was applied before any intervention and a post-test after intervention. The primary outcome was the performance in the peripheral intravenous catheter insertion skill. The comparison of correct performance in the tests was analyzed intergroup and intragroup. The effect size of the interventions was also analyzed. The t-Student and Mann-Whitney tests compared the difference between the groups. The training effect was calculated by Cohen's dm and Glass's Δ measures. RESULTS: Performance between the pre-post-test increased from 59.4% to 96% (p < 0.001) in the intervention group and from 57.8% to 93.5% in the control group (p < 0001). There was no statistical difference between the groups after intervention (p = 0225). Cohen's dm measurement was 2.95 and 3.59 in the control and intervention groups, respectively. CONCLUSIONS: The rapid cycle deliberate practice simulation strategy resulted in Licensed Practical Nurses' performance improvements in peripheral intravenous catheter insertion, evidenced by the increase of correct performance actions in the post-test compared to the pre-test. However, with no statistical difference compared to the skill-training simulation strategy.

RESUMO

BACKGROUND: Intravascular venous (VUC) or arterial (AUC) umbilical catheter placement is the most frequent invasive procedure in the neonatal intensive care unit (NICU). Either Wright's or Shukla's formula is used to introduce the catheters. However, Shukla's formula is associated with incorrect insertion, especially for newborns < 1500 g. This study aimed to determine by chest X-ray if Wright's formula is better than Shukla's formula for the correct placement of umbilical catheters in newborns ≤ 1500 g. METHODS: We included patients admitted to the NICU of a secondary-level hospital between 2021-2022 who received VUC or AUC through the Wright or Shukla formulas. RESULTS: A total of 129 newborns were included: 78 with VUC and 51 with AUC. In VUC, 50% with Wright and 36.8% with Shukla formulas had the correct location, (p = 0.24). In AUC, 56.6 % with Wright and 52.4% with Shukla formulas were placed correctly placed, (p = 0.76). VUC with weight < 1000 g were correctly placed in 36.4% with Wright and 33.3% with Shukla formulas (p = 0.58). VUC in newborns > 1000 g were correctly placed in 66.6% with Wright and 38.4% with Shukla formulas (p = 0.065). AUC in newborns < 1000 g were correctly placed in 45% using Wright and 42.9% Shukla formulas (p = 0.63). AUC in newborns > 1000 g were correctly placed in 80% using Wright and 57.1% Shukla formulas (p = 0.23). CONCLUSIONS: We found 13% more correctly placed VUC using Wright's formula. Moreover, Wright's formula was 29% above Shukla's VUC placement in neonates > 1000 g, although there was no significant difference due to the sample size.

INTRODUCCIÓN: La colocación de catéteres intravasculares venosos umbilicales (CVU) y arteriales (CAU) es el procedimiento invasivo más frecuente en la unidad de cuidados intensivos neonatales (UCIN). Para introducirlos se utilizan las fórmulas de Wright y de Shukla, aunque esta última podría estar asociada con una inserción incorrecta, especialmente en neonatos < 1500 g. El objetivo de este estudio fue determinar mediante radiografía de tórax cuál fórmula es mejor para la correcta colocación de catéteres umbilicales en recién nacidos ≤ 1500 g. MÉTODOS: Se incluyeron los pacientes ingresados en la UCIN de un hospital de segundo nivel entre 2021-2022 que recibieron CVU o CAU mediante las fórmulas de Wrigth o Shukla. RESULTADOS: Se incluyeron en total 129 recién nacidos: 78 CVU y 51 CAU. En CVU, Wright 50% y Shukla 36.8% tuvieron localización correcta, p = 0.24. En las CAU, Wright 56.6% y Shukla 52.4% tenían una ubicación correcta, p = 0.76. En CVU con peso < 1000 g, Wright 36.4% y Shukla 33.3% bien situados, p = 0.58. En CVU > 1000 g, Wright 66.6% y Shukla 38.4% bien situados, p = 0.065. En CAU < 1000 g, Wright 45% y Shukla 42.9%, p = 0.63. En CAU con peso > 1000 g, Wright 80% y Shukla 57.1%, p = 0.23. CONCLUSIONES: La colocación del CVU fue 13% mejor con la fórmula de Wright. La fórmula de Wright superó en el 29% la colocación del CVU en los neonatos > 1000 g en comparación con la de Shukla, aunque no hubo diferencia significativa debido al tamaño de la muestra.

RESUMO

BACKGROUND: Peripheral intravenous catheter (PIVC) insertion is the most common invasive procedure in the hospital setting. Ultrasound guided PIVC insertion in specific populations and settings has shown patient care benefits. OBJECTIVE: To compare the success rate of first attempts of ultrasound guided PIVC insertion performed by nurse specialists with conventional PIVC insertion performed by nurse assistants. METHOD: Randomized, controlled, single-center clinical trial registered on the ClinicalTrials.gov platform under registration NTC04853264, conducted at a public university hospital from June to September 2021. Adult patients hospitalized in clinical inpatient units with an indication for intravenous therapy compatible with a peripheral venous network were included. Participants in the intervention group (IG) received ultrasound guided PIVC performed by nurse specialists from the vascular access team, while those in the control group (CG) received conventional PIVC by nurse assistants. RESULTS: The study included a total of 166 patients: IG (n = 82) and CG (n = 84), mean age 59.5 ± 16.5 years, mostly women (n = 104, 62.7%) and white (n = 136, 81.9%). Success rate on the first attempt of PIVC insertion in IG was 90.2% and in CG was 35.7% (p < 0.001), with a relative risk of 2.5 (95% CI 1.88-3.40) for success in IG versus CG. Overall assertiveness rate was 100% in IG and 71.4% in CG. Regarding procedure performance time, the medians in IG and CG were 5 (4-7) and 10 (6-27.5) min respectively (p < 0.001). As for the incidence of negative composite outcomes, IG had lower rates compared to CG, 39% versus 66.7% (p < 0.001), generating a 42% lower probability of negative outcomes in IG, 0.58 (95% CI: 0.43-0.80). CONCLUSION(S): Successful first-try insertion was higher in the group receiving ultrasound-guided PIVC. Moreover, there were no insertion failures and IG presented lower insertion time rates and incidence of unfavorable outcomes.

RESUMO

AIM: To evaluate complications after PICC use in cancer patients. DESIGN: This was a clinical and retrospective study in which the risk factors and complications of PICC use were evaluated. METHODS: This study was carried out in the patient, emergency room, and intensive care units through the evaluation of electronic medical records. To assess the association between qualitative variables, the chi-squared test or Fisher's exact test was used, and to compare the reason for withdrawal, the Kruskal-Wallis test was applied. RESULTS: A total of 359 patients (53.5% men) with 43.1 ± 14 years who had a PICC (88% with solid tumours) were evaluated. The most common complications were mechanical complications (61.2%), infection (38%), and thrombosis (57.1%). Patients with double-lumen catheters experienced thrombosis (85.7%). This study demonstrated the effectiveness of PICC and that patients with haematological cancer are more prone to multiple PICC passages and more mechanical complications and infections.

RESUMO

Resumo: Os recém-nascidos durante o período de internação em unidade de terapia intensiva neonatal necessitam de cateterismo percutâneo no tratamento devido à gravidade clínica apresentada e à terapia de infusão necessária para a restauração das funções vitais. Na Unidade de Terapia Intensiva Neonatal, essa tecnologia é a primeira escolha quando o paciente necessita de acesso venoso a partir de 7 dias, já que o procedimento pode ser realizado à beira leito, por enfermeiros capacitados e dispensa anestesia geral. Com o tempo, o procedimento de inserção do dispositivo vascular passou por refinamentos. A tecnologia de Seldinger modificada foi uma das inovações incrementais. Entretanto, no contexto público no qual o hospital se encaixa, a incorporação de novas tecnologias é tardia e, portanto, os enfermeiros permaneciam utilizando a tecnologia convencional para cateterismo percutâneo. Assim, o estudo desenvolvido agregou novas funcionalidades e características à terapia de infusão de neonatos criticamente enfermos, resultando em ganho efetivo de qualidade no cuidado e segurança, sem alterar as funções e finalidades já existentes da tecnologia em vigor. Objetivo: implementar o uso da tecnologia de Seldinger modificada para a inserção de cateterismo percutâneo em recém-nascidos criticamente enfermos. Método: estudo quase experimental. A intervenção realizada foi a capacitação por meio da avaliação pré e pós-teste, realizada em hospital de referência. Participaram da pesquisa 48 profissionais de enfermagem (enfermeiros e técnicos). A intervenção educativa foi avaliada por meio de instrumento aplicado anteriormente para analisar os conhecimentos prévios sobre a temática, e na sequência houve o pós-teste. O instrumento de avaliação da intervenção para os enfermeiros caracterizou-se por conter 37 questões relacionadas à pré-inserção, à inserção e à manutenção do dispositivo vascular. Para os técnicos de enfermagem, o instrumento de avaliação continha 20 questões sobre os cuidados relacionados ao cateter. Foi realizada análise descritiva dos dados por técnicas estatísticas adequadas. Resultados: Para ambos os grupos, houve maior número de acertos no pós-teste do que no pré-teste. Os enfermeiros demostraram confiabilidade na inserção e manutenção do dispositivo. Na avaliação das inserções executadas por enfermeiros, através da observação direta, verificou-se melhora na realização da segunda inserção do cateter pela nova tecnologia em comparação com a primeira. Os técnicos obtiveram maior acerto nos cuidados após a capacitação. Conclusão: o processo de incorporação da tecnologia na unidade de terapia intensiva neonatal foi satisfatório. A capacitação evidenciou que os profissionais de saúde necessitam de educação continuada e permanente, e resultou em aumento do conhecimento dos profissionais de enfermagem sobre a tecnologia de Seldinger modificada.

Abstract: Newborns during their stay in a neonatal intensive care unit need percutaneous catheterization for treatment due to the clinical severity presented and the infusion therapy required to restore vital functions. In the Neonatal Intensive Care Unit, this technology is the first choice when the patient needs venous access from 7 days since the procedure can be performed at the bedside by trained nurses and does not require general anesthesia. Over time, the vascular device insertion procedure has undergone refinements. The modified Seldinger technology was one of the incremental innovations. However, in the public context in which the hospital is located, the incorporation of new technologies is late and, therefore, nurses continued to use conventional technology for percutaneous catheterization. Thus, the study developed added new functionalities and features to infusion therapy for critically ill neonates, resulting in an effective gain in quality of care and safety, without changing the existing functions and purposes of the technology in force. Objective: to implement the use of modified Seldinger technology for percutaneous catheterization insertion in critically ill newborns. Method: quasi-experimental study. The intervention was training through pre- and post-test evaluation, carried out in a reference hospital. Forty-eight nursing professionals (nurses and technicians) participated in the research. The educational intervention was evaluated by means of a previously applied instrument to analyze the previous knowledge about the theme, and then there was the post-test. The instrument to evaluate the intervention for nurses contained 37 questions related to pre-insertion, insertion, and maintenance of the vascular device. For the nursing technicians, the evaluation instrument contained 20 questions about catheter-related care. Descriptive data analysis was performed using appropriate statistical techniques. Results: For both groups, there were more correct answers in the post-test than in the pre-test. The nurses showed reliability in device insertion and maintenance. In the evaluation of the insertions performed by nurses, through direct observation, there was an improvement in the second catheter insertion using the new technology when compared to the first. The technicians were more accurate in their care after the training. Conclusion: the process of incorporating the technology in the neonatal intensive care unit was satisfactory. The training showed that health professionals need continued and permanent education and resulted in increased knowledge of nursing professionals about the modified Seldinger technology.
