RESUMEN

Occasionally, the administration of intravenous (IV) therapies can go wrong. Infiltration or extravasation is a complication when a drug or IV therapy leaks into the tissues surrounding the vascular access device. Extravasation can cause serious and often life-changing injuries. Extravasation is often associated with systemic anti-cancer therapy but non-chemotherapy drugs have been reported as having a greater risk of serious complications. This study outlines the first UK Infusion unit evaluation of the ivWatch infusion monitoring device which was undertaken from August 2023 to January 2024. Out of 2254 infusions monitored with ivWatch, the device prevented 122 cases of infiltration and extravasation from causing any harm to the patient, corresponding to a 5.4% 'check IV' notification rate.

RESUMEN

BACKGROUND: Patients with cancer can expect to receive numerous invasive vascular access procedures for intravenous therapy and clinical diagnostics. Due to the increased incidence and prevalence of cancer globally there will be significantly more people who require first-line intravenous chemotherapy over the next ten years. METHODS: Our objective was to determine the types of evidence that exist for the vascular access device (VAD) type for the delivery of systemic anti-cancer therapy (SACT) in cancer patients. We used JBI scoping review methodology to identify the types of VADs used for SACT and with a specific search strategy included articles from 2012-2022 published in the English language. We identify (i) type of VADs used for SACT delivery (ii) the type of insertion and post-insertion complications (iii) the geographical location and clinical environment (iv) and whether VAD choice impacts on quality of life (QOL). Findings were presented using the PAGER framework. MAIN FINDINGS: Our search strategy identified 10,390 titles, of these, 5318 duplicates were removed. The remaining 5072 sources were screened for eligibility, 240 articles met the inclusion criteria. The most common design include retrospective study designs (n = 91) followed by prospective study designs (n = 31). We found 28 interventional studies with 21 registered in a clinical trial registry and identified no core outcome sets papers specific to VAD for SACT. The most prevalent publications were those that featured two or more VAD types (n = 70), followed by tunnelled intravenous VADs (n = 67). Of 38 unique complications identified, the most frequent catheter related complication was catheter related thrombosis (n = 178, 74%), followed by infection (n = 170, 71%). The county where the most publications originated from was China (n = 62) with one randomized controlled multicenter study from a comprehensive cancer centre. Of the thirty three studies that included QOL we found 4 which reported on body image. No QOL measurement tools specific to the process of SACT administration via VAD are available INTERPRETATION: Our findings suggest a systematic review and meta-analysis of VAD use for intravenous SACT can be considered. However, the development of a core outcome set for SACT should be prioritised. Funding for high quality programs of research for VAD in cancer are needed. Comprehensive cancer centres should lead this research agenda.

RESUMEN

Vascular access continues to be a key factor for the reliable and safe delivery of intravenous (IV) therapy to patients in any healthcare setting. Clinical guidelines advocate for the right vascular access device selection, in order to reduce avoidable complications, eg multiple stabs, phlebitis, thrombophlebitis, insertion site infection, and blood stream infection, while improving efficiency and reducing costs. Peripheral intravenous catheters or cannulas (PIVCs) remain widely used for gaining vascular access in all clinical settings, with both adults and children, because they provide a relatively cheap and simple way to provide blood sampling and the prompt administration of IV medications. Although safe and easy to insert, PIVCs present with associated risks that can be costly to the organisation. The case studies included with this article introduce Nipro's Safetouch Cath Winged with Injection Port as a new cost-effective choice of PIVC, which is now available from NHS Supply Chain.

RESUMEN

BACKGROUND: Accurate placement of central venous access devices is important to avoid complications such as infection, thrombosis and migration. This audit aims to determine if there is a difference in complication rates and accuracy of tip position between two different intravenous jugular (IVJ) port device insertion techniques: fixation of port first (PF) versus tip first (TF). METHODS: Patients who underwent port device insertions from 2019 to 2021 at the Cairns Hospital were identified from the Australia Vascular Audit database. The primary outcome of accurate catheter tip placement (based on radiological criteria), secondary outcomes of line infection, thrombosis and other outcomes such as removal rates were gathered and compared between the 2 groups of port first (PF) versus tip first (TF) insertion. RESULTS: Two-hundred and twenty-seven patients underwent port device insertions during the period of interest. 98 (43.2%) patients had a PF insertion technique and 129 (56.8%) had a TF insertion technique. In the PF group, 81.6% (P < 0.05) of lines were accurately placed compared to 69.8% (P < 0.05) in the TF group. The line related thrombosis rate was 1% (P < 0.05) in the PF group compared to 6.2% (P < 0.05) in the TF group. Rate of line infections in the PF group was 5.1% (P = 0.92) compared to 6.2% (P = 0.92) in the TF group. CONCLUSION: The port first technique for IVJ port device placement was associated with higher accuracy and lower thrombosis rates and this was statistically significant. Further studies should involve larger multicentre populations to compare results between practitioners.

RESUMEN

Catheter-related bloodstream infection (CRBI) is an important complication of catheter use for haemodialysis, but it remains unclear whether clinical outcomes following CRBI are influenced by organism type. This study aims to compare clinical outcomes following CRBI from Gram-positive and non-Gram-positive organisms. This was a retrospective cohort study of patients with kidney failure receiving haemodialysis (HD) via vascular catheters who had a documented episode of CRBI in Western Australia between 2005 and 2018. The associations between organism type, likelihood of hospitalization, catheter removal and death from CRBI were examined using adjusted logistic regression models. There were 111 episodes of CRBI in 99 patients (6.1 episodes per 1000-catheter-days at risk). Of the study cohort, 53 (48%) were male and 38 (34%) identified as Aboriginal or Torres Strait Islander. Gram-positive organisms were identified in 73 (66%) CRBI episodes, most commonly Staphylococcus aureus. Of those with non-Gram-positive CRBI, 9 (24%) were attributed to Pseudomonas aeruginosa. One-hundred and two (92%) episodes of CRBI required hospitalization and 15 (13%) patients died from CRBI. Compared with non-Gram-positive CRBI, Gram-positive CRBI was associated with an increased risk of hospitalization and catheter removal, with adjusted odds ratio of 9.34 (95% CI 1.28-68.03) and 3.47 (95% CI 1.25-9.67), respectively. There was no association between organism type and death from CRBI. Staphylococcus aureus remains the most common organism causing CRBI in HD patients. CRBI is associated with substantial morbidity, particularly CRBI attributed to Gram-positive organisms.

RESUMEN

Regular flushing and locking of totally implantable venous access devices (TIVADs) is recommended to maintain their patency when not in use. In this case report, a 73-year-old male patient received radical resection for rectal carcinoma in January 2010. A TIVAD was implanted in 2014 and a total of 12 rounds of chemotherapy of FOLFIRI was completed in 2015. During the period from 2015 to 2020, the patient never used or conducted the monthly infusion port flushing because of the inconvenience, the COVID-19 pandemic, and so on. On 18th April 2020, the patient was admitted to the radiotherapy department of Yiwu Central Hospital. The nurse evaluated the TIVAD upon admission, finding that the skin around the reservoir was normal without any sign of infection as erythema or induration of the skin overlying the implantable port but there was intraluminal occlusion of the devices. In order to re-access the catheter, discussion of a MDT was performed and several days of unremitting efforts were tried. Gratifyingly, the patient's port was re-accessed successfully without any adverse reactions. This is a rare infusion port that has not been used and maintained for 5 years. For the port that has not been used and maintained for a long time up to 5 years, the medical staff should not give up easily. During the COVID-19 pandemic, prolonging the flushing interval of TIVADs can be an optimal clinical strategy without negative outcomes.

RESUMEN

INTRODUCCIÓN: La canulación por micropunción ecodirigida de venas profundas del brazo aumenta la tasa de éxito al primer intento y reduce la probabilidad de complicaciones1 lo que redunda en la mejora de la eficiencia del procedimiento. El desplazamiento del catéter es una complicación evitable que se relaciona con mayor riesgo de flebitis, trombosis e infecciones2, así como con mayor gasto económico y por tanto una disminución de la eficiencia del procedimiento 3-8. La estrategia de selección del dispositivo de fijación (eFIX) pretende ser una herramienta que minimize las posibilidades de desplazamiento del dispositivo de acceso vascilar (DAV). OBJETIVOS: General: Analizar la influencia de la estrategia “eFIX” para la selección del dispositivo de fijación sobre el desplazamiento de los catéteres venosos implantados con punción ecodirigida. Específico: Identificar la existencia de relación entre el desplazamiento del DAV y la aparición de trombosis, flebitis y BRC. MATERIAL Y MÉTODO: Se realizó estudio observacional analítico de corte transversal. Se incluyeron todas las inserciones exitosas realizadas en los pacientes mayores de 14 años ingresados en el Hospital Universitario de La Palma que cumplían criterios para un catéter venoso tipo Midline (ML) o Catéter Central de Inserción Periférica (CCIP) entre el 1 de julio de 2021 y el 30 de junio de 2022. Se identificó como variable dependiente el desplazamiento del catéter y como variable independiente la aplicación de la estrategia de selección del sistema de fijación (eFIX) (de elaboración propia) que incluye el uso rutinario de dispositivos adhesivos (DA) con tecnología statlock y la selección de pacientes para el uso de anclajes subtutáneos (ASC) y adhesivo tisular. Análisis de datos con estadística descriptiva con medida de efecto OR (AU)


INTRODUCTION: Ul trasound-guided micropuncture cannula tion of deep veins of the arm increases the success rate at the first attempt and reduces the probability of complications, which results in an improvement in the efficiency of the procedure. Displacement of the catheter is an avoidable complica tion that is related to a higher risk of ph lebitis, thrombosis, and infectionsb as well as greater financial costs and, there fore, a decrease in the efficiency of the procedure. OBJECTIVE: To analyze the in fluence of the "eFIX" fixation device se lection strategy on the displacement of venous catheters implanted with ultra sound-guided puncture. MATERIAL AND METHOD: A cross-sectional analytical observational study was carried out. It included all pa tients older than 14 years admitted to the University Hospital of La Palma who met the criteria for a Midline (ML) or Central Peripherally Inserted Catheter (PICC) between July 1, 2021 and June 30. 2022. Displacement of the catheter was identi fied as a dependent variable and the ap plication of the self-made fixation system selection strategy (eFIX) as an indepen dent variable, which includes the routine use of adhesive devices (AD) with statlock technology and the selection of patients for the use of subcutaneous an chors (ASC) and tissue adhesive.

RESUMEN

Introdução: Os ports são cada vez mais aceitos no meio médico e por pacientes. Por ser um dispositivo totalmente implantável, requer menores cuidados locais, diminuindo a possibilidade de infecção ou outras complicações inerentes aos acessos centrais de longa duração. Levando-se em conta o risco das complicações, faz-se necessário analisar a prevalência de complicações após inserção dos ports, a fim de avaliar a eficácia e segurança do procedimento e identificar possíveis falhas do processo. Objetivo: Avaliar a prevalência de complicações após inserção de acessos venosos centrais totalmente implantáveis pela equipe de cirurgia vascular. Método: O estudo foi realizado na enfermaria e ambulatório da cirurgia vascular do Hospital do Servidor Público Municipal ­ SP, e incluiu pacientes atendidos no período de agosto de 2022 a agosto de 2023. Resultados: A amostra deste estudo foi constituída por 62 pacientes oncológicos, sendo 17 do sexo masculino (27%) e 45 do sexo feminino (73%). A comorbidade mais prevalente foi a Hipertensão Arterial Sistêmica isolada ou associada a outras doenças (40,3%, 25 pacientes). A neoplasia mais frequente foi o adenocarcinoma de colo em 14 pacientes (22,6%). Quanto ao acesso, a veia jugular interna direita foi a mais utilizada (50 pacientes, totalizando 80,6%). Quanto às complicações, estas estiveram ausentes em 56 pacientes (90,3%). Desconexão de cateter foi observada em 1 paciente (1,6%), hematoma infectado em 1 (1,6%), hematoma local em 1 (1,6%), hematoma em pós-operatório imediato em 1 (1,6%), infecção em 1 (1,6%), e trombose de veia jugular interna direita em 1 (1,6%). Em 60 pacientes não houve dificuldade de manuseio (96,8%), e em 5 pacientes o dispositivo necessitou ser retirado (8,1%). No total ocorreram 10 óbitos (16,1%) enquanto 52 pacientes permaneceram vivos após a avaliação (83,9%). Conclusão: A prevalência de complicações relacionadas à inserção de cateter em nossa amostra foi bastante reduzida, tendo sido identificadas em apenas 6 pacientes (9,7% do total). Desconexão de cateter, hematoma infectado, hematoma local, hematoma em pós-operatório imediato, infecção e trombose de veia jugular direita foram identificadas cada uma em um único paciente.

RESUMEN

INTRODUCTION: During the COVID-19 pandemic, bloodstream infection (BSI) rates were substantially rising in Sungai Buloh Hospital (HSB). It is believed that the COVID-19 pandemic has had an adverse impact on BSI incidence caused by contaminated periphery vascular catheters (PVCs). The study's objective is to reduce the BSI rates in HSB by improving adherence to the PVC care bundle via the Plan-Do-Study-Act (PDSA) approach. MATERIALS AND METHODS: A quality improvement (QI) project was employed over four months, from June to September 2021, during the COVID-19 pandemic in HSB. All adults hospitalised for COVID-19 with intravenous lines were subjected to data collection. A baseline audit was conducted to study BSI incidence from April to May 2021. Implementation was carried out by PDSA cycles and data on BSI rates per 100 admissions was described using a monthly run chart. RESULTS: At baseline, the BSI rate per 100 admissions was 5.44 before implementing our QI project. Initial changes via PDSA cycles did not bring significant improvements to BSI rates and a rising trend in BSI rates was observed after two PDSA cycles. Further audits identified the problem of noncompliance with the practice of aseptic non-touch technique (ANTT) and a lack of effective leadership in implementing the PVC care bundle. The third PDSA cycle focused on adopting practical leadership skills among senior clinicians to ensure compliance with the prevention bundle and to encourage the use of ultrasound guidance for difficult line insertion. After the third PDSA cycle, the BSI rate per 100 admissions was reduced from 6.41 to 4.34 (p < 0.05). The BSI rates continued to decline down the line for another five months. CONCLUSION: Through QI initiatives, the risk of BSI can be significantly reduced.

RESUMEN

Background: Portal vein thrombosis is a disease with potentially deleterious outcomes including portal vein hypertension and intestinal infarction. The factors contributing is various; however, dogs with with acute portal vein thrombosis or multiple thromboses are less likely to survive. Therefore, acute development of portal hypertension has a requires an immediate treatment. Case Description: A 10-year-old Dalmatian was referred for syncope and azotemia, hyperammonemia. After each examinations including computed tomography scan, we diagnosed with acute portal vein thrombosis with unknown cause. A portal vein port was inserted to prevent and control the portal vein thrombus. The port was placed in abdomen subcutaneously after the position of the catheter were stabilized. Low-molecular-weight heparin was injected from the port to manage thrombosis after the operation. This case responded well to this treatment. Syncope and azotemia, hyperammonemia resolved and no relapse of thrombosis was found 6 months after the operation. Conclusion: Implantable vascular access port is a drug delivery system with the advantage of dealing with treatment-resistant acute portal vein thrombosis.

RESUMEN

The risk for venous thromboembolism (VTE) is considered to be low in the general paediatric intensive care unit (PICU) population, and pharmacological thromboprophylaxis is not routinely used. PICU patients considered at high-risk of VTE could possibly benefit from pharmacological thromboprophylaxis, but the incidence of VTE in this group of patients is unclear. This was an observational, prospective study at a tertiary multi-disciplinary paediatric hospital. We used comprehensive ultrasonography screening for VTE in critically ill children with multiple risk factors for VTE. Patients admitted to PICU ≥ 72 h and with ≥ two risk factors for VTE were included. Patients receiving pharmacological thromboprophylaxis during their entire PICU stay were excluded. The primary outcome of the study was VTEs not related to the use of a CVC. Ultrasonography screening of the great veins was performed at PICU discharge. Seventy patients with median (interquartile range) 3 (2-4) risk factors for VTE were evaluated. Median age was 0.3 years (0.03-4.3) and median PICU length of stay 9 days (5-17). Regarding the primary outcome, no symptomatic VTEs occurred and no asymptomatic VTEs were found on ultrasonography screening, resulting in an incidence of VTEs not related to a vascular catheter of 0% (95% CI: 0-5.1%). CONCLUSION: Our results indicate that VTEs not related to a vascular catheter are a rare event even in a selected group of severely ill small children considered to be at high risk of VTE. WHAT IS KNOWN: • Children in the PICU often have several risk factors for venous thromboembolism (VTE). • The incidence of VTE in PICU patients is highly uncertain, and there are no evidence-based guidelines regarding VTE prophylaxis. WHAT IS NEW: • This study found an incidence of VTEs not related to a vascular catheter of 0% (95% CI: 0-5.1%). • This indicates that such VTE events are rare even in PICU patients with multiple risk factors for VTE.

RESUMEN

PURPOSE: A totally implantable vascular access port (TIVAP) is commonly required in cancer patients. Possible adverse events after TIVAP implantation include surgical site infection (SSI) and port-related bacteremia. This study examined whether adhesive surgical drapes can reduce the risk of SSI. METHODS: A total of 100 mostly cancer patients were randomized into two groups before undergoing TIVAP implantation by surgical cut-down. In one group, an adhesive, non-impregnated drape was applied to the skin prior to incision, while the control group underwent surgery without a drape. Swabs were taken from the surgical site and sent for microbiologic testing. SSI rates were compared between groups. RESULTS: No SSI occurred within 30 days after surgery. In each group, two patients died. There were 5 complications (port thrombosis, port dislocation, two cases of pneumothorax, skin allergy), all in the intervention group (p = 0.056). Using the incision drape prolonged procedure time by + 5 min (95% CI - 1 to + 10, p = 0.125). Microbiologic swab testing failed to detect any effect of the incision drape. CONCLUSIONS: Plastic adhesive skin drapes may be unnecessary in cancer patients who undergo surgical implantation of a TIVAP.

RESUMEN

This study was to explore the application value for central venous stenosis and occlusion in hemodialysis patients under the CT angiography based on intelligent segmentation algorithm, so that patients can survive better. Spiral CT was used to examine upper limb swelling in 62 uremic hemodialysis patients at a speed of 3.8 mL/s. Nonionic iodine contrast agent was injected around the contralateral limb. The total dosage of 90-102 mL, it was scanned by intelligent trigger technology. The trigger scanning threshold was set. The monitoring point was located in the superior vena cava. CT with convolutional neural network intelligent segmentation algorithm was used to process image data. Finally, the quality of life and related biochemical levels of patients before and after hemodialysis were detected. Under the CT angiography of intelligent segmentation algorithm, 77 stenoses were found in 62 uremic patients, including 48 stenoses of the brachial vein and 17 stenoses of the superior vena cava. The correlation coefficient between CT angiography and digital subtraction angiography (DSA) imaging results of intelligent segmentation algorithm was 0.411. Segmentation effect of the algorithm in this study: automatic segmentation accuracy was greater than 79%. After hemodialysis treatment, the scores of physical fitness, pain, social function, and energy status of patients were significantly increased compared with those before treatment, and the levels of albumin, serum phosphorus, and parathyroid hormone were significantly decreased (P < 0.05). In summary, CT angiography with intelligent segmentation algorithm can obtain clear, intuitive, and complete vascular walking images, and better display subclavian vein, brachiocephalic vein, and superior vena cava. It can provide more valuable support for surgical intervention and has certain application value for better survival of hemodialysis patients.

RESUMEN

BACKGROUND: Retained intravascular catheter fragments (RICF) are a rare complication of implantable vascular access device (IVAD) removal for which there is limited understanding of aetiology. There is a varied approach to management among the currently published literature. AIMS: The aim of this study was to establish incidence, risk factors, and outcomes for RICF after attempted removal of IVADs. METHODS: A single institution retrospective review was undertaken of individuals ≤ 25 years undergoing removal of IVADs from October 2014 to June 2019. Risk factors for RICF were explored using univariable logistic and Cox regression analysis. RESULTS: Six cases of RICF were identified among 654 line removal episodes (0.92% (95% CI 0.37-2%)) in patients aged 6-17 years (median 11, IQR 6-15 years). The main risk factor for RICF at removal was found to be line duration (OR 3.5/year, 95% CI 2.1-5.84, p < 0.0001). No RICFs occurred in lines indwelling for < 3 years. Five children with RICF ≤ 16 years were discussed with a paediatric cardiothoracic centre, and all were left in situ with 4 remaining asymptomatic. One had the fragment tip extruded through a wound, which required trimming. The other (17 years of age) developed an infected sinus for which partial removal with open excision followed by full removal with endovascular snare retrieval was performed by the adult vascular surgeons. CONCLUSION: IVADs in-situ for longer than a three-year period are at greatest risk of RICF upon removal. Management with transfixion of line fragments to surrounding muscle seems prudent while invasive attempts at retrieval appear unwarranted.

RESUMEN

BACKGROUND: An increased incidence of thrombotic complications in patients with coronavirus disease 2019 (COVID-19) has been reported. Severe acute kidney injury (AKI) is one of the major clinical manifestations of COVID-19 with the need for renal replacement therapy. It was observed that hemodialysis (HD) accesses tended to thrombose more often in the COVID-19 population than in non-COVID-19 patients. We hypothesize that the hypercoagulable state of COVID-19 is associated with higher incidence of access clotting. METHOD: In this retrospective single-centered study at Kings County Hospital in New York City, 1,075 patients with COVID-19 were screened, and 174 patients who received HD from January 3, 2021 to May 15, 2020 were enrolled to examine the risk factors of dialysis access clotting in patients with COVID-19. RESULTS: Of the 174 patients, 109 (63%) were COVID-19 positive. 39 (22.6%) patients had dialysis access clotting at least once during their hospitalization, and they had significantly higher body mass index (BMI) (p = 0.001), higher rates of COVID-19 (p = 0.015), AKI (p < 0.001), higher platelet counts (p = 0.029), higher lactate dehydrogenase levels (p = 0.009), and lower albumin levels (p = 0.001) than those without access malfunctions. Low albumin levels (p = 0.008), AKI (p = 0.008), and high BMI (p = 0.018) were risk factors associated with HD access clotting among COVID-19 patients. CONCLUSION: Patients with COVID-19 who receive HD for AKI with high BMI are at a higher risk of clotting their HD access.
