Establishing a plan to improve pediatric patient comfort during PIV insertions and blood specimen collection: a quality improvement effort.

HIGHLIGHTS: Patient comfort during peripheral intravenous (PIV) insertion and specimen collection was increased. The authors extended the contingency plan implemented for PICC insertion to include PIV insertion and specimen collection. The authors met their goals by using quality improvement methodology. Prioritizing patient comfort often requires institutional culture change. BACKGROUND: Needle procedures can cause pain and distress, especially in pediatric patients.1 Retrospective data collected at a freestanding pediatric facility revealed that approximately 30% of pediatric patients were not demonstrating sufficient levels of comfort during peripheral intravenous (PIV) catheter insertion and specimen collection (lab draws) even after successful implementation of comfort measures by the vascular access team (VAT) in an adjacent procedure (eg peripherally inserted central catheter placement). The current quality improvement project was implemented to support adaptation and expansion of previous lessons learned to PIVs and lab draws specifically. DESIGN AND METHODS: The VAT used the Pediatric Sedation State Scale,2 a standardized assessment tool integrated into the electronic medical record, to assess procedural comfort during PIVs and lab draws from February 2021 through April 2023. A total of 24 134 patients aged 0 to 18 years were included in the data collection. Interventions were delivered concurrently and included (1) reeducation/ongoing support for implementation of the Comfort Promise3 measures, (2) the creation and implementation of advanced comfort options, and (3) culture change. AIMS AND OBJECTIVES: The goal of the interventions was to improve the percentage of pediatric patients achieving adequate levels of comfort beginning at 68% in year 1 to 90% in year 2. RESULTS: From February 2021 to April 2023, the VAT team was able to improve procedural comfort scores from 68% to 90% of pediatric patients with adequate comfort for lab draws and/or PIV insertions. CONCLUSIONS: While standard comfort measures are a good first step in pain management during needle procedures, they are not sufficient for every pediatric patient. Nitrous, sedation, and the use of anxiolytics and analgesics can play an important role in reducing pain and anxiety during needle procedures and should be considered for patients not achieving adequate levels of comfort with standard comfort measures.

Beyond traditional venous access: Midline catheter use in pediatric apheresis.

The objective of this study was to assess the use of midline catheters as venous access for apheresis procedures in pediatric patients. A retrospective analysis of medical records was conducted from September 2019 to June 2022 to evaluate the safety and efficacy of midline catheters for therapeutic pediatric apheresis. During the study period, a total of 121 procedures were inserted in 22 unique patients. The age of the subjects ranged from 2.7 to 21 years. The blood flow rates achieved with midline catheters met or exceeded the recommended rates for apheresis in children (40 mL/min), by the Wilcoxon signed-rank test (p < 0.0001). There was one episode of catheter-related thrombosis, but no cases of bloodstream infection or catheter dislodgement were reported. In conclusion, this study supports the use of midline catheters as a safe and effective alternative for venous access during therapeutic and donor apheresis procedures in pediatric patients.

[Intraosseous vascular access - step by step]. / Intraossärer Zugang ­ Schritt für Schritt.

Probably everyone who works in emergency medicine has been in the situation of having to insert a peripheral vein under time pressure in difficult venous conditions. So what do I do if I don't succeed? Establish a peripheral venous catheter? In recent years, the intraosseous approach has become increasingly popular as an alternative procedure. In this article, you will be guided step by step through the creation of an intraosseous access.

Evolution of distal limb perfusion management in adult peripheral venoarterial extracorporeal membrane oxygenation with femoral artery cannulation.

Limb ischaemia is a clinically relevant complication of venoarterial extracorporeal membrane oxygenation (VA ECMO) with femoral artery cannulation. No selective distal perfusion or other advanced techniques were used in the past to maintain adequate distal limb perfusion. A more recent trend is the shift from the reactive or emergency management to the pro-active or prophylactic placement of a distal perfusion cannula to avoid or reduce limb ischaemia-related complications. Multiple alternative cannulation techniques to the distal perfusion cannula have been developed to maintain distal limb perfusion, including end-to-side grafting, external or endovascular femoro-femoral bypass, retrograde limb perfusion (e.g., via the posterior tibial, dorsalis pedis or anterior tibial artery), and, more recently, use of a bidirectional cannula. Venous congestion has also been recognized as a potential contributing factor to limb ischaemia development and specific techniques have been described with facilitated venous drainage or bilateral cannulation being the most recent, to reduce or avoid venous stasis as a contributor to impaired limb perfusion. Advances in monitoring techniques, such as near-infrared spectroscopy and duplex ultrasound analysis, have been applied to improve decision-making regarding both the monitoring and management of limb ischaemia. This narrative review describes the evolution of techniques used for distal limb perfusion during peripheral VA ECMO.

Increased risk of complications in lower versus upper limb peripheral intravenous cannulation in children with severe neurological impairment.

BACKGROUND: Obtaining peripheral intravenous catheter (PIVC) access in children with severe neurological impairment (SNI) is often challenging and commonly associated with complications, including dislodgement, phlebitis and extravasation. In severe cases, extravasation injury may lead to tissue necrosis, ulceration and long-term morbidity. The aim of this study was to determine the relative incidence of PIVC complications secondary to lower limb cannulation, compared to upper limb, in children with SNI. METHODS: A single centre, retrospective, observational review was conducted. Patients with SNI, admitted at a tertiary paediatric centre over 6 months between July and December 2022, were included. RESULTS: One-hundred fifty-five PIVC procedures were conducted in 110 children over the study period. Complications were more common in lower limb PIVCs (12/16, 75%) compared to upper limb (58/139, 42%), p = 0.01. CONCLUSION: Upper limb cannulation is preferred in children with SNI.

A New Equation to Estimate Peripherally Inserted Central Catheter Length.

Background and Objectives: Peripherally inserted central catheter (PICC) placement plays an important role in clinical practice. This study aimed to provide an equation for the proper estimation of catheter length in cases of PICC placement without imaging guidance in relation to patient height, weight, sex, and age. Materials and Methods: For 1137 PICC placement cases in both arm veins of 954 patients at a single center, the elbow crease to the cavoatrial junction length (ECL) was calculated as follows: ECL = (PICC length) + (distance from the elbow crease to the puncture site). We analyzed the relationship between ECL and patient characteristics and suggested a new equation for ECL based on height, weight, sex, and age. Results: The average ECL was 48.0 ± 2.4 cm in the right side and 51.0 ± 3.0 cm in the left side. ECL in the right arm was significantly correlated with patient height, sex, and age, whereas the ECL in the left arm was additionally significantly correlated with patient weight. The ECL (cm) prediction model was as follows: right ECL = 26.32 + 1.33 × (female = 1, male = 2) - 0.02 × age (years) + 0.13 × height (cm); left ECL = 22.09 + 1.28 × (female = 1, male = 2) + 0.02 × age (years) + 0.14 × height (cm) + 0.042 × weight (kg). Conclusions: The appropriate PICC length was predicted based on the patient's height, weight, sex, and age. The equations in our study can help predict the optimal catheter length and can be automatically calculated using computerized patient information for bedside procedures in PICC.

Routine preprocedural ultrasound in palpation versus ultrasound guided radial access for cardiac catheterization.

BACKGROUND: The radial first approach in cardiac catheterization is preferred for its benefits in patient comfort and recovery time. Yet, challenges persist due to characteristics like small, deep, calcified, and mobile radial arteries. Utilizing ultrasound before and during procedures can improve success rates. However, the adoption of its use is still limited and subject to debate. AIM: To utilize routine preprocedural ultrasound (US) and compare US guided with palpation guided radial access, focusing on operator efficiency and outcomes. METHODS AND RESULTS: Consenting adult patients undergoing elective radial cardiac catheterization were divided into palpation and US groups. Routine preprocedural assessment of radial artery characteristics was performed using handheld US. Baseline data, US findings, procedural outcomes, and clinical outcomes were compared in 182 participants (91 in each group). US guided radial access had significantly higher first pass success rates (76.92% vs. 49.45%, p 0.0001), fewer number of attempts (1.46 ± 1 vs. 1.99 ± 1.46, p 0.004), and shorter amount of time (93.62 ± 44.04 vs. 120.44 ± 67.1, p 0.002) compared with palpation guidance. The palpation group had significantly higher incidence of spasm (15.38% vs. 3.3%, p 0.0052). Subgroup analysis indicated consistent benefits of US guidance, especially in calcified radial arteries. CONCLUSION: This prospective, nonrandomized, single-center study demonstrated that real-time procedural US improved the operator's time and effort and enhanced patient comfort compared with palpation. US guidance use was particularly favorable in the presence of calcifications observed on baseline preoperative US.

The distal radial artery: Versatile vascular access for transcatheter interventions.

Conventional transradial access has been established as the gold standard for invasive coronary angiography and percutaneous interventions by the current European and American guidelines. The distal or snuffbox radial artery access represents an alternative transradial access site that allows radial sheath insertion with the patient's hand pronated. Firstly described 40 years ago, it exploded in popularity only recently. Promising additional benefits, the distal radial access is increasingly being adopted in various types of percutaneous interventions, being preferred by many interventional cardiologists and radiologists for its reduced vascular complications and time to hemostasis, and improvement of patient and operator comfort. Other centers consider it a fad, waiting for solid clear evidence and benefits. The evidence is dynamic and discrepant, depending on the center, the operator, and how it was collected (randomized controlled vs observational studies). Another essential aspect raised by "skeptics" was whether distal radial access, by its smaller diameter and more angled course, can support all types of interventions. The aim of this review is to gather all the scenarios where distal radial access has been utilized and to conclude whether this vascular access is feasible across all transcatheter interventions.

Stent graft implantation from distal radial access-A novel way to treat femoral access site complication during transcatheter aortic valve replacement: A case report.

In this paper, a case of an 82-year-old man who was admitted to our department with sever symptomatic degenerative aortic valve stenosis is presented and discussed. After all screening procedures, a successful transfemoral transcatheter aortic valve replacement was performed, but the closure of the femoral access was unsuccessful due to suture-based device failure. We decided to perform a prolonged balloon dilatation and external compression at the bleeding site, but the bleeding did not stop; therefore, an iCover stent graft was implanted from distal radial artery access using slender technique. Following that, the bleeding was stopped, and the patient had an uneventful outcome.

Ultrasound-guided peripheral intravenous canulation by emergency nurses: A systematic review and meta-analysis.

BACKGROUND: Peripheral intravenous cannulation is a common procedure in the emergency department. Nevertheless, failure rates during the first attempt are as high as 40% in adults and 65% in children. Evidence suggests that physician performed ultrasound-guided peripheral intravenous cannulation (USG-PIVC) is an effective alternative to the traditional method; however, there is insufficient data on the efficacy of the technique performed by nurses. OBJECTIVE: To examine the efficacy of the USG-PIVC technique performed by emergency department nurses. METHODS: A literature review with meta-analysis was performed. The databases used were PubMed, Scopus and CINAHL. The search was conducted in March 2023. Two meta-analysis one of clinical trials about the effectiveness and one about the succession rate were performed. RESULTS: 20 studies were selected and analysed. The studies showed that USGPIVC performed by emergency nurses increased the probability of both the overall success and a successful first attempt compared to the standard technique. In addition, patients showed high satisfaction and lower complication rates. However, the procedure had no significant effect on the time or number of attempts required. A lower probability of success was obtained as regards peripheral intravenous cannulation when the standard technique was used, OR = 0.42 (95 %CI 0.25-0.70p < 0,05). CONCLUSIONS: Ultrasound-guided peripheral intravenous cannulation performed by emergency nurses is a safe and effective technique.

Manejo de PICC en el Servicio de Urgencias de un hospital universitario / Use of PICC at the University Hospital Emergency Unit

Para gestionar el capital venoso del paciente con seguridad y responsabilidad es necesario aumentar la calidad de los cuidados proporcionados, unificando y estandarizando los criterios de actuación, basándose siempre en la mejor evidencia científica. Las enfermeras de los Servicios de Urgencias deben aplicar la evidencia en el manejo del catéter venoso central de inserción periférica (PICC), conocer el protocolo aprobado por la Dirección Asistencial de su hospital y, sobre todo, evitar la variabilidad en la actuación, que podría aumentar los riesgos relacionados con la atención sanitaria, así como la desconfianza del paciente. Mantener actualizados los conocimientos y promover la adquisición de habilidades en la práctica clínica es de suma importancia para garantizar cuidados de calidad en el manejo de este tipo de catéteres, debiéndose comprobar periódicamente el grado de cumplimiento de la evidencia recogida en los protocolos existentes en el hospital. Las enfermeras tienen el reto de estar al día en el manejo de los accesos vasculares, y deben responder con seriedad y evidencia a los cuidados que necesitan los pacientes a los que se atienden. En este manuscrito se objetiva la necesidad de formar y capacitar de forma continua a los profesionales para el manejo adecuado del PICC. (AU)

In order to manage the venous resource of the patient safely and with responsibility, it is necessary to increase the quality of care provided, unifying and standardizing performance criteria, always based on the best scientific evidence. Emergency Unit nurses must apply evidence in their use of the peripherally inserted central venous catheter (PICC), they must know the protocol approved by the Patient Care Management in their hospital and, most of all, must avoid variability of action, which could increase the risks associated with healthcare as well as mistrust by patients. It is extremely important to keep an updated knowledge and to promote the acquisition of clinical practice skills, in order to guarantee quality care in the use of this type of catheters; the level of compliance of the evidence collected in the hospital protocols must be confirmed periodically. Nurses face the challenge of being updated in the management of vascular accesses, and must give response with seriousness and evidence to the care needed by their patients. This manuscript sets out objectively the need for continuous training and qualification for professionals regarding the adequate use of PICC. (AU)

Effectiveness of near-infrared light devices for peripheral intravenous cannulation in children and adolescents: A meta-analysis of randomized controlled trials.

OBJECTIVES: To examine the effectiveness of near-infrared light devices (NIR) on procedure time of successful cannulation, success rate at the first attempt, and pain scores among pediatric patients and explore potential covariates on the intervention effect. BACKGROUND: Pediatric patients have encountered a high failure rate as compared with adult patients using traditional cannulation. NIR devices might help to access veins with an optimum viewing area and eliminate the number of attempts. However, methodological limitations and inconsistent results from previous reviews were found. METHODS: A three-step comprehensive search was performed in nine databases. Meta-analysis, subgroup, and meta-regression analyses were conducted. Individual quality assessment and certainty of evidence were assessed using the Cochrane risk of bias tool and the Grading of Recommendations, Assessments, Development, and Evaluation criteria, respectively. RESULTS: We included 18 randomized controlled trials (RCTs) with 5298 children and adolescents across nine countries. NIR light devices significantly reduce -29.43 s of procedure time and -0.47 attempts of peripheral intravenous cannulation compared with traditional methods. Subgroup analysis observed a significantly large effect size on procedure time using AccuVein with pre-procedure training at the clinics. However, NIR light devices do not significantly decrease the procedure time, first attempt success rate, and pain scores. Meta-regression identified sample size as a significant covariate that had an impact on the success rate at the first attempt. CONCLUSIONS: The near-infrared light device can statistically significantly reduce the procedure time and the number of attempts. Given the low or very low certainty of the evidence, future well-designed RCTs are necessary.

Spiced RCT: Success and Pain Associated with Intravenous Cannulation in the Emergency Department Randomized Controlled Trial.

BACKGROUND: Peripheral venous cannulation is one of the most common procedures in medicine. A larger cannula allows higher rates of fluid to be provided if needed in a deteriorating patient; however, it is also perceived that larger-gauge cannula placement is associated with increased pain and procedural difficulty. OBJECTIVE: This study aimed to compare the pain and procedural difficulty experienced during insertion between 18-gauge (18G) and 20-gauge (20G) cannulas. METHODS: We conducted a single-blinded, randomized controlled trial on adult patients who required peripheral IV cannulation within a tertiary hospital emergency department between April and October 2018. Patients were randomized to either the 18G or 20G cannula group. The primary outcomes of the study-pain experienced by patients and procedural difficulties experienced by clinical staff-were recorded on two separate 10-cm visual analog scales. Other outcomes include first-attempt success rate, operator designation, complications, and the intent and actual use of the IV cannula were documented on preformatted questionnaires. RESULTS: Data from 178 patients were included in the analysis. Eighty-nine patients were allocated to each cannula group. There were no statistically or clinically significant differences between mean pain score (0.23; 95% CI 0.56-1.02; p = 0.5662) and mean procedural difficulty score (0.12; 95% CI 0.66-0.93; p = 0.7396). between the two groups. There was no difference in first-attempt success rate (73 of 89 vs. 75 of 89; p = 0.1288), complications (2 of 89 vs. 1 of 89) between the 20G group and 18G group, respectively. CONCLUSIONS: There was no significant difference between the 18G or 20G cannula for either pain experienced by patients or procedural difficulty experienced by clinicians.

Length of hospitalization, APPLE score, and number of intravenous catheters placed at admission are associated with increased odds of peripheral intravenous catheter complications in dogs.

OBJECTIVE: To identify risk factors associated with peripheral intravenous catheter (PIVC) complications in dogs hospitalized in the critical care unit (CCU). ANIMALS: 107 dogs admitted to the CCU between October 2022 and March 2023. METHODS: This prospective, observational clinical trial was performed at a single veterinary teaching hospital. Dogs hospitalized in the CCU for at least 24 hours were evaluated for enrollment. PIVC were placed following a standardized protocol and monitored for complications. PIVC complications were classified as extravasation, phlebitis, dislodgement, occlusion, line breakage, or patient removal. RESULTS: Median PIVC dwell time was 46.50 hours (range, 24.25 to 159.25 hours). Overall PIVC complication rate was 12.1% (13/107), with phlebitis (4/107 [3.7%]) and extravasation (4/107 [3.7%]) being the most frequently recorded complications. Multivariable analysis identified increasing length of hospitalization (LOH; OR, 1.43; 95% CI, 1.04 to 1.97; P = .029), an acute patient physiologic and laboratory evaluation full (APPLEFULL) score > 35 (OR, 4.66; 95% CI, 1.09 to 19.90; P = .038), and having 2 PIVCs placed at admission (OR, 10.92; 95% CI, 1.96 to 60.73; P = .006) as risk factors for PIVC complication. CLINICAL RELEVANCE: Increasing LOH, an APPLEFULL score > 35 and having 2 PIVCs placed at admission were associated with increased odds for PIVC complication in this study. Although these are independent risk factors for PIVC complication, the combination of increasing LOH, an APPLEFULL score > 35, and having 2 PIVCs placed at admission may represent a more severely ill population, drawing attention to a vulnerable group of dogs at risk for PIVC complication.

Safety and learning curve of percutaneous axillary artery access for complex endovascular aortic procedures.

BACKGROUND: Percutaneous axillary artery access is increasingly used for large-bore access during interventional vascular and cardiac procedures. The aim of this study was to evaluate the safety and learning curve of percutaneous axillary artery access in patients undergoing complex endovascular aortic repair (fenestrated and branched endovascular aneurysm repair [FBEVAR]) requiring large-bore upper extremity access and to discuss best practices for technique and complication management. METHODS: One-hundred forty-six patients undergoing large-bore percutaneous axillary artery access during FBEVAR in a prospective, nonrandomized, Investigational Device Exemption study between September 2017 and January 2023 were analyzed. Ultrasound guidance and micropuncture were used to access the second portion of the axillary artery and 2 Perclose Proglide or Prostyle devices (Abbott Vascular) were predeployed before the insertion of the large-bore sheath. Completion angiography was performed in all patients to verify hemostatic closure. Axillary artery patency was also assessed on follow-up computed tomography angiography. Patient-related, procedural, and postoperative variables were collected and analyzed. RESULTS: One-hundred forty-five patients underwent successful percutaneous axillary artery access; 1 patient failed axillary access and alternative access was established. The left axillary artery was accessed in 115 patients (79%), and the right axillary artery was accessed in 30 patients (21%). The largest profile sheath was 14 F in 4 patients (2.8%), 12F in 133 patients (91.7%), and 8F in 8 patients (5.5%). Ten patients (6.9%) required covered stent placement (Viabahn, W. L. Gore & Associates) for failure to achieve hemostasis; there were no conversions to open surgical repair. Additional adverse events included transient upper extremity weakness in two patients (1.3%) and transient upper extremity paresthesias in two patients (1.3%). Three patients (2%) suffered postoperative strokes, including one unrelated hemorrhagic stroke and two possibly access-related embolic strokes. On follow-up, axillary artery patency was 100%. There was a trend toward decreased closure failure over time, with seven patients (10%) in the early cohort and three (4%) in the late cohort. There was a significant negative correlation between the cumulative complication rate and the cumulative experience. CONCLUSIONS: Large-bore percutaneous axillary artery access provides safe upper extremity large-bore access during FBEVAR, achieving successful closure in >90% of patients with a low incidence of access-related complications. There was a trend toward better closure rates with increasing experience, suggesting a learning curve effect. Application of best practices including ultrasound guidance and angiography may ensure safe application of the technique of percutaneous large-bore axillary artery access.

Pain and Satisfaction Perceptions of Ultrasound-Guided Versus Conventional Peripheral Intravenous Catheterization: A Randomized Controlled Trial.

BACKGROUND: While many emergency department (ED) patients need peripheral vascular catheterization, diagnosis and treatment are often delayed by difficult intravenous access (DIVA). AIMS: This study of ED patients with DIVA was designed to evaluate ultrasound (US)-guided peripheral intravenous (IV) catheterization, compare it with conventional catheterization, and analyse patient pain and satisfaction regarding catheterization. DESIGN: Randomized controlled clinical trial. METHODS: Adult patients treated in the ED who scored >3 on the Adult-Difficult Venous Catheterization scale were randomly assigned to either US-guided or conventional peripheral IV catheterization. Data were collected from April to December 2016. Study variables were catheter insertion success, number of catheterization attempts, time required to perform the procedure, catheter length and calibre, puncture site, complications, and catheter functioning. Pain and patient satisfaction were also analysed for each group and the full sample. RESULTS: 120 and 138 patients were recruited for the US-guided and conventional peripheral IV catheterization groups, respectively. For the US-guided compared to the conventional procedure, insertion success was greater (91.75% versus 89.9%; p=0.04), the mean (SD) number of attempts was lower (1.29 (0.59) versus 1.81 (1.28); p<0.001), mean (SD) satisfaction was greater (7.59 (2.04) versus 6.69 (2.28); p=0.03), and the mean (SD) required time in minutes was greater (7.89 (7.13) versus 5.1 (3.69); p=0.045). Mean (SD) pain was moderate in both groups (4.6 (2.75) versus 4.33 (2.91) (p=0.32). Logistic regression for the full sample indicated that more attempts and greater pain were both associated with reduced satisfaction, while use of higher-calibre catheters was associated with greater satisfaction. CONCLUSION: US-guided compared to conventional peripheral IV catheterization in patients with DIVA was more successful, required fewer attempts, enabled use of longer and higher-calibre catheters, and led to greater patient satisfaction. Patients who underwent US-guided intravenous catheterization reported moderate pain, similar to that reported for the conventional procedure. CLINICAL IMPLICATIONS: US-guided peripheral intravenous catheterization improves ED patient care, as it requires fewer catheterization attempts. It is especially recommended for patients with DIVA.

Implementation of Tunneled Peripherally Inserted Central Catheters Placement in Cancer Patients: A Randomized Multicenter Study.

This study sought to evaluate the impact of the subcutaneous tunneling technique on peripherally inserted central catheter (PICC) placement. We randomized 694 patients who needed PICC placement to either the tunneled PICCs (experimental group) or the non-tunneled PICCs (control group) from August to December 2021. The cumulative frequency of complications was assessed as the primary outcome. Secondary outcomes comprised of the amount of bleeding, catheter insertion time, self-reported pain score, and one-puncture success rate. After 6 months of follow-up, the tunneled PICCs group showed a significant decrease in the frequency of total complications, especially in infection (3.0% vs. 7.1%, p = .021) and catheter-related thrombosis (3.3% vs. 8.3%, p = .008), although approximately 0.5 ml bleeding and 3.5 min time were increased. This randomized multicenter study supports the efficacy of subcutaneous tunneling technology in reducing PICC-related complications, enhancing patient comfort, and encouraging using subcutaneous tunneling technology for PICC placement.

Difficult Intravascular Access in Pediatric Emergency Department: The Ultrasound-Assisted Strategy (DIAPEDUS Study).

Vein line positioning represents one of the first diagnostic and therapeutic steps in Pediatric Emergency Department (PED); however, the outcome of this maneuver is frequently not as expected, especially for difficult-to-access (DIVA) patients. The standard technique (visual-palpatory) has a low success rate; hence ultrasound (US) assistance has been suggested for DIVA patients, although controversial results have been obtained. Our study compared the success rate of an intravascular (IV) access procedure at the first attempt, with and without ultrasound assistance, in pediatric DIVA patients. Secondary objectives were the global success rate, the mean procedural time, the IV device's life span, and the complications rate. We conducted an observational, prospective, monocentric, no-profit cohort study enrolling 110 patients presenting to our ED, aged 0-21 years. All the patients were considered difficult-to-access patients according to the DIVA score (≥4) or history of previous difficult intravascular access. They were randomized into two homogeneous groups: 50 patients with the standard and 60 with the US-assisted technique. We obtained a significantly higher success rate at first attempt with the US-guided technique (90% vs 18%, p ≤ .00001). Moreover, the overall success rate was higher in the US group (95% vs 46%, p < .00001). The mean procedural time resulted significantly less in the US group (2.7 ± 2.2 min vs 10 ± 6.4 min, p < .0001), as well as the overall number of attempts to obtain a stable IV line (1.09 ± 0.34 attempts vs 2.38 ± 1.09 attempts, p < .0001). We experienced some post-procedural complications without differences in the two groups, although none were severe. Our study showed that bedside ultrasound assisting implantation of peripheral venous access in pediatric DIVA patients improves first-time success rate, overall success rate, procedural time, and patient comfort, reducing the number of attempts to obtain a stable IV line.

The role of hospital-based vascular access teams and implications for patient safety: A multi-methods study.

BACKGROUND: Peripherally inserted central catheters (PICCs) and midline catheters are often placed by nurse-led vascular access teams (VATs). While some data regarding the effectiveness of these teams exists, less is known about their structure and function. OBJECTIVES: To examine the roles, functions, and composition of VATs related to the use and management of PICC and midline catheters. METHODS: A descriptive, multi-method study that included an online survey of 62 hospitals participating in a quality improvement consortium and qualitative interviews with 74 hospital-based clinicians in 10 sites. Interviews were recorded, transcribed, and analyzed using a rapid analysis and matrix approach. The survey, which contained closed-ended, categorical questions, was analyzed using frequencies and percentages. RESULTS: More than 77% (n = 48) of hospitals had an on-site VAT. The average team size was seven nurses; their primary function was device insertion. Interview findings revealed that teams varied in characteristics and functions. Interviewees described the broad role that teams play in device insertion, care and removal, and in educating/training hospital staff. However, we found that teams' role in decision making, particularly related to appropriate device selection, was limited and, in some cases, met with physician resistance. CONCLUSIONS: To realize the full benefit of VATs, changes in hospital culture, along with an increased willingness from physicians to integrate VAT nurses in decision making, may be needed. Future interventions aimed at engaging and empowering teams appear necessary.

Bilateral Femoral Cannulation Is Associated With Reduced Severe Limb Ischemia-Related Complications Compared With Unilateral Femoral Cannulation in Adult Peripheral Venoarterial Extracorporeal Membrane Oxygenation: Results From the Extracorporeal Life Support Registry.

OBJECTIVES: Peripheral venoarterial extracorporeal membrane oxygenation (ECMO) with femoral access is obtained through unilateral or bilateral groin cannulation. Whether one cannulation strategy is associated with a lower risk for limb ischemia remains unknown. We aim to assess if one strategy is preferable. DESIGN: A retrospective cohort study based on the Extracorporeal Life Support Organization registry. SETTING: ECMO centers worldwide included in the Extracorporeal Life Support Organization registry. PATIENTS: All adult patients (≥ 18 yr) who received peripheral venoarterial ECMO with femoral access and were included from 2014 to 2020. INTERVENTIONS: Unilateral or bilateral femoral cannulation. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the occurrence of limb ischemia defined as a composite endpoint including the need for a distal perfusion cannula (DPC) after 6 hours from implantation, compartment syndrome/fasciotomy, amputation, revascularization, and thrombectomy. Secondary endpoints included bleeding at the peripheral cannulation site, need for vessel repair, vessel repair after decannulation, and in-hospital death. Propensity score matching was performed to account for confounders. Overall, 19,093 patients underwent peripheral venoarterial ECMO through unilateral ( n = 11,965) or bilateral ( n = 7,128) femoral cannulation. Limb ischemia requiring any intervention was not different between both groups (bilateral vs unilateral: odds ratio [OR], 0.92; 95% CI, 0.82-1.02). However, there was a lower rate of compartment syndrome/fasciotomy in the bilateral group (bilateral vs unilateral: OR, 0.80; 95% CI, 0.66-0.97). Bilateral cannulation was also associated with lower odds of cannulation site bleeding (bilateral vs unilateral: OR, 0.87; 95% CI, 0.76-0.99), vessel repair (bilateral vs unilateral: OR, 0.55; 95% CI, 0.38-0.79), and in-hospital mortality (bilateral vs unilateral: OR, 0.85; 95% CI, 0.81-0.91) compared with unilateral cannulation. These findings were unchanged after propensity matching. CONCLUSIONS: This study showed no risk reduction for overall limb ischemia-related events requiring DPC after 6 hours when comparing bilateral to unilateral femoral cannulation in peripheral venoarterial ECMO. However, bilateral cannulation was associated with a reduced risk for compartment syndrome/fasciotomy, lower rates of bleeding and vessel repair during ECMO, and lower in-hospital mortality.
