Efficacy of radial artery cannulation in treatment of cardiac arrest: A case report.

RATIONALE: Timely treatment and recovery of cardiac arrest in out-of-hospital settings present significant challenges. This report describes a novel method of integrating advanced monitoring techniques such as radial artery cannulation in the treatment of an 85-year-old male patient who suffered an out-of-hospital cardiac arrest (OHCA). PATIENT CONCERNS: The patient, an 85-year-old man, experienced sudden cardiac arrest at home around 4:10 pm on November 22, 2023, characterized by immediate loss of consciousness and absence of pulse, and no response when called by name, necessitating urgent medical intervention. DIAGNOSES: The patient was diagnosed with OHCA by the emergency doctor, which was further confirmed by the absence of spontaneous circulation and respiratory failure. INTERVENTIONS: The patient was treated with manual cardiopulmonary resuscitation (CPR), ventilator-assisted ventilation, internal jugular venous catheterization, medical treatment, mechanical CPR, and supplemented by radial artery cannulation for invasive blood pressure monitoring. This technique was pivotal for real-time hemodynamic assessment. OUTCOMES: The invasive monitoring facilitated the early detection of the return of spontaneous circulation, allowing for the timely cessation of mechanical CPR. Subsequent treatment in the intensive care unit was optimized based on continuous arterial pressure readings, enhancing the stabilization of the patient's condition. LESSONS: This case underscores the significant role of radial artery cannulation for invasive blood pressure monitoring in improving clinical outcomes for patients experiencing OHCA. Integrating radial artery cannulation with other advanced monitoring techniques aids in the early detection of the return of spontaneous circulation and optimizes subsequent intensive care treatment.

Neurologic complications in patients receiving aortic versus subclavian versus femoral arterial cannulation for post-cardiotomy extracorporeal life support: results of the PELS observational multicenter study.

BACKGROUND: Cerebral perfusion may change depending on arterial cannulation site and may affect the incidence of neurologic adverse events in post-cardiotomy extracorporeal life support (ECLS). The current study compares patients' neurologic outcomes with three commonly used arterial cannulation strategies (aortic vs. subclavian/axillary vs. femoral artery) to evaluate if each ECLS configuration is associated with different rates of neurologic complications. METHODS: This retrospective, multicenter (34 centers), observational study included adults requiring post-cardiotomy ECLS between January 2000 and December 2020 present in the Post-Cardiotomy Extracorporeal Life Support (PELS) Study database. Patients with Aortic, Subclavian/Axillary and Femoral cannulation were compared on the incidence of a composite neurological end-point (ischemic stroke, cerebral hemorrhage, brain edema). Secondary outcomes were overall in-hospital mortality, neurologic complications as cause of in-hospital death, and post-operative minor neurologic complications (seizures). Association between cannulation and neurological outcomes were investigated through linear mixed-effects models. RESULTS: This study included 1897 patients comprising 26.5% Aortic (n = 503), 20.9% Subclavian/Axillary (n = 397) and 52.6% Femoral (n = 997) cannulations. The Subclavian/Axillary group featured a more frequent history of hypertension, smoking, diabetes, previous myocardial infarction, dialysis, peripheral artery disease and previous stroke. Neuro-monitoring was used infrequently in all groups. Major neurologic complications were more frequent in Subclavian/Axillary (Aortic: n = 79, 15.8%; Subclavian/Axillary: n = 78, 19.6%; Femoral: n = 118, 11.9%; p < 0.001) also after mixed-effects model adjustment (OR 1.53 [95% CI 1.02-2.31], p = 0.041). Seizures were more common in Subclavian/Axillary (n = 13, 3.4%) than Aortic (n = 9, 1.8%) and Femoral cannulation (n = 12, 1.3%, p = 0.036). In-hospital mortality was higher after Aortic cannulation (Aortic: n = 344, 68.4%, Subclavian/Axillary: n = 223, 56.2%, Femoral: n = 587, 58.9%, p < 0.001), as shown by Kaplan-Meier curves. Anyhow, neurologic cause of death (Aortic: n = 12, 3.9%, Subclavian/Axillary: n = 14, 6.6%, Femoral: n = 28, 5.0%, p = 0.433) was similar. CONCLUSIONS: In this analysis of the PELS Study, Subclavian/Axillary cannulation was associated with higher rates of major neurologic complications and seizures. In-hospital mortality was higher after Aortic cannulation, despite no significant differences in incidence of neurological cause of death in these patients. These results encourage vigilance for neurologic complications and neuromonitoring use in patients on ECLS, especially with Subclavian/Axillary cannulation.

Using Simulation Models to Train Clinicians in the Use of Point-of-Care Ultrasound.

The use of point-of-care ultrasound (POCUS) has shown to be a beneficial non-invasive vascular access assessment method by clinicians, which can provide critical elements of visual and measurable information that proves to be useful in the context of vascular access cannulation, in combination with the practical skill of the clinician performing the cannulation. However, the use of POCUS in this context is to practically train and enable individuals who are novices in using this technique to become proficient in performing this task subsequently on patients in a careful and successful way. The simulation of these vascular conditions may be useful to help healthcare professionals learn, understand, apply, and establish such practical skills for vascular cannulation safely to achieve the desired outcomes. This project intended, through the attendance of a half-day workshop, to establish skills to use POCUS in connection with simulation models and perform specific tasks to enable clinicians to use this method in their clinical practice for vascular access cannulation in patients. A mixed-methods longitudinal study design was used to evaluate the effect of a point-of-care ultrasound workshop for peripheral intravenous cannula insertion, including specific tasks for the participants to be performed on simulation models. A total of 81 individuals participated in 11 half-day workshops through 2021 and 2022. Offering a workshop that uses simulation models in combination with various POCUS devices is useful in establishing this newly learned skill in clinicians, such as measurements of depth, caliper, and direction of a vein with POCUS prior to cannulation providing essential anatomical facts to the operator, which increases the likelihood of first-time success in cannulation.

Protect peripheral intravenous catheters: a study protocol for a randomised controlled trial of a novel antimicrobial dressing for peripheral intravenous catheters (ProP trial).

INTRODUCTION: Peripheral intravenous catheters (PIVCs) are the most commonly used vascular access device in hospitalised patients. Yet PIVCs may be complicated by local or systemic infections leading to increased healthcare costs. Chlorhexidine gluconate (CHG)-impregnated dressings may help reduce PIVC-related infectious complications but have not yet been evaluated. We hypothesise an impregnated CHG transparent dressing, in comparison to standard polyurethane dressing, will be safe, effective and cost-effective in protecting against PIVC-related infectious complications and phlebitis. METHODS AND ANALYSIS: The ProP trial is a multicentre, superiority, randomised clinical and cost-effectiveness trial with internal pilot, conducted across three centres in Australia and France. Patients (adults and children aged ≥6 years) requiring one PIVC for ≥48 hours are eligible. We will exclude patients with emergent PIVCs, known CHG allergy, skin injury at site of insertion or previous trial enrolment. Patients will be randomised to 3M Tegaderm Antimicrobial IV Advanced Securement dressing or standard care group. For the internal pilot, 300 patients will be enrolled to test protocol feasibility (eligibility, recruitment, retention, protocol fidelity, missing data and satisfaction of participants and staff), primary endpoint for internal pilot, assessed by independent data safety monitoring committee. Clinical outcomes will not be reviewed. Following feasibility assessment, the remaining 2624 (1312 per trial arm) patients will be enrolled following the same methods. The primary endpoint is a composite of catheter-related infectious complications and phlebitis. Recruitment began on 3 May 2023. ETHICS AND DISSEMINATION: The protocol was approved by Ouest I ethic committee in France and by The Queensland Children's Hospital Human Research Ethics Committee in Australia. The findings will be disseminated through presentation at scientific conferences and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05741866.

Prevention of complications related to peripherally inserted central catheter insertion techniques in newborns: systematic review and network meta-analysis.

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.

Vascular access specialist teams versus standard practice for catheter insertion and prevention of failure: a systematic review.

OBJECTIVE: Billions of vascular access devices (VADs) are inserted annually for intravenous therapy worldwide. However, their use is not without challenges. Facilitating the process and enhancing results, hospital authorities have created vascular access specialist teams (VASTs) with advanced competencies in the evaluation, insertion, care and management of VADs. The objective is to compare the effectiveness of VASTs versus standard practice regarding cannulation success and vascular access maintenance in hospitalised adults. DESIGN: Systematic review, using the Mixed Methods Appraisal Tool. DATA SOURCES: We conducted a structured data search on Cochrane Library, MEDLINE, Web of Science, Scopus and EBSCOhost up to 31 May 2023. We did not impose a time limit regarding the date of publication. ELIGIBILITY CRITERIA: Studies were eligible for inclusion in the review if they were randomised and non-randomised trials and observational studies. DATA EXTRACTION AND SYNTHESIS: We included studies that described or evaluated the activity of VASTs compared with clinical practitioners. The outcomes analysed were the success of the cannulation and the incidence of associated adverse effects. RESULTS: The search strategy produced 3053 papers published between 1984 and 2020, from which 12 were selected for analysis. VASTs are heterogeneously described among these studies, which mainly focus on insertions, frequently for patients with difficult intravenous access. Some patients presented with specific needs or requirement for specific insertion technique or catheter type. Compared with usual practice, these studies indicate that the involvement of a VAST is associated with a higher effectiveness in terms of first attempt insertions and insertion success rates, and a reduction in catheter-associated adverse events. However, meta-analyses confirming this trend are not currently possible. CONCLUSIONS: It seems apparent that VASTS contribute to improving the health of patients during the administration of intravenous. VASTs seem to increase the effectiveness of VAD insertion and care and reduce complications. PROSPERO REGISTRATION NUMBER: CRD42021231259.

Using Implementation Science to Improve Short Peripheral Intravenous Catheter Outcomes.

Short peripheral intravenous catheters (short PIVCs) are commonly used in acute care, guided by evidence-based policy with interventions to limit premature failure. Research on how nurses use evidence and change processes to optimize outcomes is needed. The study objective was to use a theory-based implementation science approach to evaluate and improve short PIVC insertion and care processes and reduce removals for adverse outcomes in acute care. This mixed-methods study was conducted with inpatient nursing units (n = 23) at a large urban quaternary medical center. Units identified and implemented one PIVC care intervention that could lower catheter removals for adverse outcomes over 3 months. Data from multiple sources were convergently analyzed to evaluate process and outcomes postintervention. Although overall frequency of PIVC removals for adverse outcomes was unchanged, several units improved their outcomes using implementation strategies. The determinant framework provides a plausible explanation for the study results. While adverse outcome rates remained below published rates, some units had limited success improving outcomes with traditional change strategies. Implementation strategies and readily accessible data can offer nursing units a new approach to effectively deploy, monitor, and maintain interventions to achieve improved outcomes.

Operational Definition of the Concept of Success in Peripheral Intravenous Catheterization in Hospitalized Children.

The objective of this study was to operationally define the concept of success in peripheral intravenous catheterization in children considering the Walker and Avant model. This is a methodological study, carried out through the following steps: concept selection, the definition of the analysis objective, identification of possible uses of the concept, determination of critical or essential attributes, construction of a model and opposite case, and identification of antecedents and consequences. The study was carried out based on a search in international databases from January to March 2021. The sample consisted of 47 studies conducted in 17 countries between 2008 and 2021. Five attributes, 20 antecedents, 10 consequences, and an empirical reference of the studied concept were identified. Also, 2 cases, model and opposite, were elaborated, and an operational definition of the concept was developed. The Walker and Avant method enabled the operationalization of the concept of success of peripheral intravenous catheterization in children based on attributes, antecedents and consequents, and model and opposite cases.

Randomised controlled trials in vascular access devices in emergency departments: a scoping review protocol.

BACKGROUND: The significance of vascular access devices for patients in the emergency department (ED) is undeniable. When it comes to evaluating the effectiveness of interventions, randomised controlled trials (RCTs) stand out as the most reliable sources of evidence compared with other study designs. AIM: To explore and synthesise the findings from RCTs related to vascular access devices in the ED setting. METHODS: A systematic search will be conducted in electronic medical databases including the Cochrane Central Register of Controlled Trials, Pubmed, CINAHL and Embase databases. All RCTs focusing on peripheral intravenous catheters, central venous catheters and intraosseous catheters, published in English and Chinese in peer-reviewed journals within the past decade, will be included. CONCLUSION: This scoping review will summarise the current state of evidence for vascular access devices in the ED setting. This will identify gaps in the literature and, in turn, assist clinicians and researchers in pinpointing areas for future exploration and provide a valuable guide for future research.

Development and evaluation of a PICC virtual simulator in neonatal nursing: A randomized controlled trial.

BACKGROUND: Peripherally Inserted Central Catheter (PICC) is essential in neonatal care, especially for critically ill infants. Traditional training for neonatal PICC insertion faces challenges such as high costs and limited practice opportunities. Virtual simulation technology has emerged as a potential training tool, providing a realistic, risk-free learning environment. OBJECTIVES: The study aimed to assess the effectiveness of a virtual simulation teaching system in neonatal PICC care training, focusing on improving nursing students' knowledge， skills and interest in pediatric nursing. DESIGN: A quasi-experimental design was used, with assessments conducted before and after the activity. PARTICIPANTS: The study involved 58 graduate nursing students from China Medical University, divided into experimental and control groups. METHODS: The System Usability Scale (SUS) was utilized to assess teachers' experiences with the PICC virtual simulation software. Students' perceptions of the software and their interest in pediatric nursing were measured using Self-Administered Questionnaires. Furthermore, Theoretical and Operational Assessments were applied to determine the extent of students' knowledge and practical skills before and after experimentation. RESULTS: Teachers and students have favorably evaluated the software system, with notable improvements in theoretical scores following testing. While the virtual simulation system does not enhance practical skills, it does increase student interest in pediatric nursing and employment. CONCLUSIONS: This neonatal virtual simulation software serves as a complement to, rather than a replacement for, traditional clinical training. Its integration into educational programs significantly enhances learning outcomes.

The effect of a pushing technique with normal saline on peripheral intravenous catheter placement success in paediatric haematology and oncology: A randomized controlled trial.

PURPOSE: The aim of the present study is to determine the effect of the pushing technique with saline on the success of peripheral IV catheter placement in a paediatric haematology and oncology sample. METHODS: The randomized controlled trial was conducted among 60 paediatric haematology and oncology patients aged between 0 and 17. The participants were randomly assigned to two peripheral intravenous catheter placement groups (intervention group, n:30, control group, n:30). Each patient was evaluated with the Difficult Intravenous Access (DIVA) score before being included in the study. Each patient was assessed using the Personal Information Form for Children and Catheter Registration Form. RESULTS: The average age of the children was 86.4 months (SD = 60.0); 36.7% were female. The pushing technique with saline significantly increased the success of placing a peripheral IV catheter on the first attempt in the intervention group compared to the control group (F = 42.391, p = 0.000). The number of attempts during peripheral IV catheter placement significantly decreased in the intervention group compared with the control group (t = -5.676, p = 0.000). Complications were less in the intervention group compared with the control group (χ2 = 24.438, p = 0.000). The procedure time was significantly shorter in the intervention group compared with the control group (t = -4.026, p = 0.000). CONCLUSION: The pushing technique with saline is an effective method to increase the first attempt success rate, decrease the number of attempts, reduce the procedure time, and reduce the complications during peripheral intravenous catheter placement procedures in paediatric haematology and oncology patients with difficult intravenous access.

Double arterial vs. single axillary cannulation in acute type A aortic dissections: a meta-analysis.

Aim: To evaluate the effects of double (axillary and femoral) vs. single (axillary) cannulation on early outcomes of acute type A aortic dissection (ATAAD). Materials & methods: Meta-analysis using PubMed/MEDLINE, Scopus, and Cochrane databases through August 23, 2023. Focused on operative mortality, postoperative stroke, re-exploration for bleeding, spinal cord injury, and renal replacement therapy. Results: Among 5 propensity score-matched studies with 2127 patients, double cannulation showed comparable mortality and higher rates of postoperative stroke (pooled odds ratio: 1.69, 95% confidence interval: 1.19-2.39) and need for renal replacement therapy (pooled odds ratio: 1.35, 95% confidence interval: 1.13-1.60) compared with single cannulation. Conclusion: Double arterial cannulation in ATAAD surgery is associated with increased postoperative stroke and renal replacement therapy than single cannulation.

What is this summary about? We studied the optimal way to maintain blood flow during surgery for acute aortic dissection. We focused on comparing the use of one tube placement site in the axillary artery with two sites, both in the axillary and femoral arteries, in five previous studies.What were the results? Using two sites was associated with a higher risk of stroke and need for dialysis after surgery than using only one site.What do the results mean? Adding a tube in the femoral artery for blood flow may increase the risk of complications. It appears that placing the tube only in the axillary artery may be a safer choice for appropriately selected patients having this surgery.

Surgical removal of a peripheral venous catheter fragment in the heart in a preterm infant.

Peripheral venous catheter fracture with cardiovascular embolization is a rare but potentially serious complication. Herein, we report a case of peripheral venous catheter fracture with embolization in right ventricle in a preterm infant. The catheter fragment was successfully removed by surgical procedure via median sternotomy under cardiopulmonary bypass(CPB).We hope this case will increase awareness of this rare complication and improve cannulation safety.

Use of Esmarch bandage does not increase peripheral vein size in healthy volunteers: A randomized clinical trial.

INTRODUCTION: Ultrasound is used for peripheral intravenous (PIV) cannulation in patients with difficult landmark-guided IV access in the Emergency Department. Distal-to-proximal application of an Esmarch bandage on the target limb has been suggested as a method for increasing vein size and ease of cannulation. METHODS: This study was a single-blinded crossover randomized controlled trial comparing basilic vein size under ultrasound with use of an Esmarch bandage in addition to standard IV tourniquet ("tourniquet + Esmarch") compared to use of a standard IV tourniquet alone. Participant discomfort with the tourniquet + Esmarch was also compared to that with standard IV tourniquet alone. RESULTS: Twenty-two healthy volunteers were used to measure basilic vein size with and without the Esmarch bandage. There was no difference in basilic vein size between the two groups, with a mean diameter of 6.0 ± 1.5 mm in the tourniquet + Esmarch group and 6.0 ± 1.4 mm in the control group, p = 0.89. Discomfort score (from 0 to 10) was different between the groups, with a mean discomfort score of 2.1 in the tourniquet + Esmarch group and 1.1 in the standard IV tourniquet alone group (p < 0.001). CONCLUSIONS: This study showed that the use of an Esmarch bandage does not increase basilic vein size in healthy volunteers but is associated with a mild increase in discomfort.

Development and evaluation of an algorithm for peripheral venous catheter placement (ALCOV): protocol for a quasi-experimental study.

INTRODUCTION: Multiple punctures during peripheral venous catheter (PVC) placement increase the risk of complications. Scoring for adult difficult intravenous access (A-DIVA Scale) exists but has never been assessed in the framework of a care algorithm (scoring associated with a new decision-making tree for puncture conditions, the A-DIVA Tree). We seek to implement an catheter placement algorithm to decrease the mean number of punctures per patient. The algorithm will be adjusted based on obstacles and levers revealed by the analysis of clinical data. The benefits of the algorithm will be assessed using a step-by-step implementation of the approach. METHODS AND ANALYSIS: 794 PVC placements will be recorded in two inclusion centres (50%/50%). In phase I, 297 PVC placements will be collected, and 16 individual semistructured interviews will be conducted to evaluate the centres' practices. In phase II, 200 PVC placements will be recorded to assess the impact of the A-DIVA Scale alone. The interphase will allow preliminary results based development of the A-DIVA Tree. In phase III, 297 PVC placements will be recorded to assess the impact of the algorithm on the mean number of punctures per patient. ETHICS AND DISSEMINATION: The study and related consent forms were approved by an institutional review board (Comité de Protection des Personnes Sud-Méditerranée I) on 25 April 2023 under reference number 2023-A00223-42. The results will be disseminated in the form of original articles, presentations and guidelines. TRIAL REGISTRATION NUMBER: NCT05935228.

Long-term intravenous devices: a narrative review of their placement.

PURPOSE OF REVIEW: This review summarizes the latest findings and recommendations about the characteristics, indications and use of peripheral and central long-term venous access devices.The various complications inherent in these devices are becoming better known, and their contributing factors determined, which could make it possible to reduce their incidence. RECENT FINDINGS: Some measures are integrated into recommendations for good practice, such as appropriate selection of devices, the preferential use of the thinnest catheters, and cyanoacrylate glue and dressings impregnated with chlorhexidine. SUMMARY: Improving understanding of the phenomena leading to infectious and thrombotic complications, as well as better knowing the differences between intravenous devices and their respective indications, should lead to improvement of in-hospital and out-of-hospital care.

Experiences and perceptions of critical care nurses on the use of point-of-care ultrasound (POCUS) to establish peripheral venous access in patients with difficult intravenous access: a qualitative study.

OBJECTIVES: This study aims to explore and describe critical care nurses' (CCNs') experiences and perceptions of using point-of-care ultrasound (POCUS) to establish peripheral intravenous access in patients with difficult intravenous access (DIVA). DESIGN: A qualitative design with a hermeneutic approach was chosen for this study. From May to August 2022, data were collected using individual, face-to-face, and digital semistructured interviews and analysed using Braun and Clarke's reflexive thematic analysis. SETTING: The study were conducted in six intensive care units in both Norway and Sweden. PARTICIPANTS: Nine CCNs experienced in using point-of-care ultrasound (POCUS) to establish peripheral intravenous access in patients with DIVA were recruited. RESULTS: Data analysis led to the construction of the overarching theme: 'POCUS simplifies a complicated procedure' based on the following five subthemes: 'Sharing the experience', 'Seeing inside the body', 'Independent in establishing difficult intravenous access', 'Using POCUS to increase action readiness', and 'Appreciating an expanded role as critical care nurses'. CONCLUSION: Ultrasound-guided peripheral intravenous access can become a valuable skill for CCN's caring for patients with DIVA in the intensive care unit. This practice can potentially reduce patient suffering, improve patient outcomes, enable the CCN to provide high-quality care, improve action readiness, time management and job satisfaction for the nurses.
