Long guidewire peripheral intravenous catheters in emergency departments for management of difficult intravenous access: A multicenter, pragmatic, randomized controlled trial

BACKGROUND

A quarter of patients who present to emergency departments (EDs) have difficult intravenous access (DIVA), making it challenging for clinicians to successfully place a peripheral intravenous catheter (PIVC). Some literature suggests that guidewire PIVC improves first-insertion success rate.

AIM

The aim was to determine the clinical and cost-effectiveness of a novel long PIVC (5.8 cm) with a retractable coiled guidewire (GW-PIVC) for patients with DIVA, compared with standard care PIVCs.

METHODS

A pragmatic randomized controlled trial was conducted in two Australian EDs. Eligible participants were adults assessed as meeting DIVA criteria. Participants were randomized (1:1 ratio; stratified by hospital) to either GW-PIVC (long) or standard care group (short or long PIVC). The use of ultrasound was discretionary in the standard care group and was recommended in the GW-PIVC group due to the pragmatic design that was primarily testing the GW-PIVC rather than the ultrasound use. Primary outcome was first-insertion success and secondary outcomes included all-cause device failure, patient and staff satisfaction, and cost-effectiveness. The analysis was intention to treat.

RESULTS

A total of 446 participants were randomized and 409 received PIVCs. The use of GW-PIVC, compared with standard PIVC, had a lower first-insertion success rate (68% vs. 77%, odds ratio [OR] 0.65, 95% confidence interval [CI] 0.43-0.99, p < 0.05). There was no difference in PIVC failure (134.0 per 1000 catheter days [GW-PIVC] vs. 111.8 [standard PIVC] per 1000 catheter days, hazard ratio 1.18, 95% CI 0.72-1.95). Both participant (8/10 vs. 9/10, median difference [MD] -1.00, 95% CI -1.37 to -0.63) and clinician (8/10 vs. 10/10, MD -2.00, 95% CI -2.37 to -1.63) satisfaction was lower with GW-PIVCs compared with standard PIVCs. More nurses inserted standard PIVCs than GW-PIVCs (56.9% vs. 36.5%) and had less confidence in their ultrasound skills (28.0% vs. 46.6% self-claimed as advanced/expert users). The cost per participant of GW-PIVC insertions was 2.46 times greater than standard PIVC insertions ($AU80.24 vs. $AU32.57).

CONCLUSIONS

GW-PIVCs had significantly lower first-insertion success and non-significantly higher all-cause catheter failure. Additional training and device design familiar to clinicians are vital factors to enhance the likelihood of successful future implementation of GW-PIVCs.

End-stage renal disease in a critical patient with superior vena cava syndrome with central vein catheters inserted via the superficial femoral vein: A case study

Superior vena cava syndrome (SVCS) is caused by obstruction to the blood flow through this vein. Indwelling central venous devices, such as cardiac pacemakers and haemodialysis catheters have emerged as the most common benign aetiology of SVCS. SVCS is particularly severe in patients with end-stage renal disease who require continuous renal replacement therapy plus infusion therapy. The presence of SVCS results in a reduction of available venous access for affected patients. Therefore, venous access plays a crucial role in the management of these patients. The importance of dealing with vascular access (VA) in critical patients with these conditions cannot be overstated. This case describes an 81-year-old man with respiratory failure who had end-stage renal disease complicated with SVCS. Using ultrasound-guided puncture, we inserted a peripherally inserted central catheter (PICC) into the superficial femoral vein to meet his infusion requirements in intensive care. After successful placement, the catheter tip position was adjusted using imaging to position the tip relative to the haemodialysis catheter. Whenever patients with severe renal dysfunction are treated, central veins should be preserved. Safe PICC access is possible via the superficial femoral vein to protect the last central VA for rational use. This meets urgent needs for infusion and deserves promotion.

Quality of life in women with breast cancer undergoing neoadjuvant chemotherapy: comparison between PICC and PICC-port

BACKGROUND

Peripherally inserted central catheters (PICCs) and new type of arm-port, the PICC-port, are currently used for neoadjuvant chemotherapy treatment in patients with breast cancer. We aimed to compare Quality of Life (QoL) of patients receiving one of these two devices investigating overall satisfaction, psychological impact, as well as the impact on professional, social and sport activities, and local discomfort.

METHODS

We did a prospective observational before-after study of PICCs versus PICC-ports. Adult (aged ≥ 18 years) females with breast cancer candidate to neoadjuvant chemotherapy were included. The primary outcome was QoL according to the Quality-of-Life Assessment Venous Device Catheters (QLAVD) questionnaire assessed 12 months after device implantation.

RESULTS

Between May 2019 and November 2020, of 278 individuals screened for eligibility, 210 were enrolled. PICC-ports were preferred over PICCs with a QLAVD score of 29 [25; 32] vs 31 [26; 36.5] (p = 0.014). Specifically, most QLAVD constructs related to psychological impact, social aspects, and discomfort were in favor of PICC-ports vs PICC, especially in women under the age of 60. Overall, pain scores at insertion and during therapy administration were not significantly different between the two groups, as well as infection, secondary malpositioning, thrombosis, or obstruction of the device.

CONCLUSIONS

In women with breast cancer undergoing neoadjuvant chemotherapy, PICC-ports were overall better accepted than PICCs in terms of QoL, especially in those who were younger. Device-related complications were similar.

Midline catheters for blood gas and acid/base monitoring in critical patients: A prospective observational study

BACKGROUND

Arterial lines and central venous catheter (CVC) allow to monitor patients' acid-base status and gas exchange. Their placement and maintenance may however be burdened by severe complications. Midline Catheters (MC) are peripheral venous accesses that are less invasive and easier to insert compared to CVC and arterial lines.

METHODS

A prospective observational study was performed including stabilized critical patients with clinical indication to midline positioning before intensive care unit (ICU) discharge. The primary aim was to assess if venous sampling from MCs can be a reliable alternative to CVC for pH and CO2 monitoring. The secondary aim was to evaluate the correlation between samplings from MC, CVC and arterial line with regards to pH, carbon dioxide tension (pCO2), lactates and electrolytes. Three samples from CVC, arterial line and MC were collected simultaneously. Agreement and correlation of the studied parameters between different sampling sites were explored.

RESULTS

40 patients were included in the analysis. A good agreement for pH and pCO2 was recorded between MC and CVC: mean differences were 0.001 (95% CI -0.006 to 0.007) and 0.7 (-0.1 to 1.5), percentage error 0.4% and 11.2%, respectively. Correlation between MC and both central venous and arterial samples for pH, pCO2, lactates and electrolytes was found to be moderate-to-strong (Pearson's R coefficient range 0.59-0.99, p < 0.001 for all these parameters).

CONCLUSIONS

In stabilized critical patients, midline catheters represent a reliable alternative to CVC and arterial lines to monitor acid-base disturbances, CO2 levels and electrolytes. The present findings add to the known advantages of MC, which might be considered a first-line vascular access for non-critical or stabilized patients who do not require infusion of vesicant or irritant drugs.

Registered Nurses' Association of Ontario (RNAO) best practice guideline on the assessment and management of vascular access devices

INTRODUCTION

Vascular access is the most common invasive procedure performed in health care. This fundamental procedure must be performed in a safe and effective manner. Vascular access devices (VADs) are often the source of infections and other complications, yet there is a lack of clear guidance on VADs for health providers across different settings. A Best Practice Guideline (BPG) was developed by the Registered Nurses' Association of Ontario (RNAO) to provide evidence-based recommendations on the assessment and management of VADs.

METHODS

RNAO BPGs are based on systematic reviews of the literature following the GRADE approach. Experts on the topic of vascular access were selected to form a panel. Systematic reviews were conducted on six research areas: education, vascular access specialists, blood draws, daily review of peripheral VADs, visualization technologies, and pain management. A search for relevant research studies published in English limited to January 2013 was applied to eight databases. All studies were independently assessed for eligibility and risk of bias by two reviewers based on predetermined inclusion and exclusion criteria. The GRADE approach was used to determine certainty of the evidence.

RESULTS

Over 65,000 articles were screened related to the six priority research questions. Of these, 876 full-text publications were examined for relevance, with 174 articles designated to inform nine recommendations in the BPG on the subject areas of: comprehensive health teaching, practical education for health providers, blood draws, daily review of peripheral VADs, visualization technologies, and pain management. In June 2021, the RNAO published the BPG on vascular access, which included the recommendations and other supporting resources.

CONCLUSION

The vascular access BPG provides high quality guidance and updated recommendations, and can serve as a primary resource for health providers assessing and managing VADs.

Effectiveness of a nurse-led peripherally inserted central catheter service: A retrospective cohort study

BACKGROUND

A multitude of challenges arises from the growing utilisation of peripherally inserted central catheters (PICCs), including the ability to provide timely, effective and safe insertion, which must be ensured and prioritised in patient care. A nurse-led model of care has become more prevalent as PICCs become extensively needed due to their applications. However, despite their widespread use, such intervention is yet in its inception in Saudi Arabia, and thereby, evaluating the outcomes of this service is of utmost importance to support patient safety initiatives and quality of care.

PURPOSE

This research aims to assess the effectiveness of a nurse-led PICC placement service.

METHODS

A quantitative retrospective cohort design was used. The sample of this study was 333 random subsets of records on PICC insertion for adult patients between 1st April 2019 and 31st March 2023 in a tertiary medical facility in Riyadh, Saudi Arabia.

RESULTS

A nurse-led PICC service demonstrated an overall successful placement of 330 cases (99.1%), out of which 323 PICCs (97%) were successfully inserted under intra-cavitary electrocardiogram (IC-ECG) guidance, while 7 PICCs (2.1%) were successfully inserted with fluoroscopy. The overall complication rate was 2.35 occurrences per 1000 CL days, whereas the complication rate within the first 10 days after PICC insertion was 0.42 per 1000 CL days.

CONCLUSION

A nurse-led model for PICC insertion has remarkably high success rates and low rates of complication, highlighting the pivotal role of a specialised PICC team. This service boasted a commendable track record of achieving a high rate of success in its implementation, implying that a nurse-led PICC service operates effectively to improve the patient experience by delivering timely and high-quality healthcare service.

A GAVeCeLT consensus on the indication, insertion, and management of central venous access devices in the critically ill

Central venous access devices are essential for the management of critically ill patients, but they are potentially associated with many complications, which may occur during or after insertion. Many evidence-based documents-consensus and guidelines-suggest practical recommendations for reducing catheter-related complications, but they have some limitations. Some documents are not focused on critically ill patients; other documents address only some special strategies, such as the use of ultrasound; other documents are biased by obsolete concepts, inappropriate terminology, and lack of considerations for new technologies and new methods. Thus, the Italian Group of Venous Access Devices (GAVeCeLT) has decided to offer an updated compendium of the main strategies-old and new-that should be adopted for minimizing catheter-related complications in the adult critically ill patient. The project has been planned as a consensus, rather than a guideline, since many issues in this field are relatively recent, and few high-quality randomized clinical studies are currently available, particularly in the area of indications and choice of the device. Panelists were chosen between the Italian vascular access experts who had published papers on peer-reviewed journals about this topic in the last few years. The consensus process was carried out according to the RAND/University of California at Los Angeles (UCLA) Appropriateness Methodology, a modification of the Delphi method, that is, a structured process for collecting knowledge from groups of experts through a series of questionnaires. The final document has been structured as statements which answer to four major sets of questions regarding central venous access in the critically ill: (1) before insertion (seven questions), (2) during insertion (eight questions), (3) after insertion (three questions), and (4) at removal (three questions).

Adverse events with arterial catheters in intensive care units: a scoping review

INTRODUCTION

The installation of an arterial line is one of the invasive procedures performed for hemodynamic monitoring and, even with its clear importance in intensive care, it is still an invasive procedure and liable to cause harms to the patients.

OBJECTIVE

To identify the adverse events associated with the use of arterial catheters in critically-ill patients in the world scientific production.

METHODOLOGY

The present scoping review was conducted according to the JBI methodology for scoping reviews. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist was used for reporting. The research question was "Which adverse events related to the use of arterial catheters in patients admitted to intensive care are more evident in the literature?". Data collection took place in the following databases: LILACS; MEDLINE; EMBASE; CINAHL, EBSCOhost; and WEB OF SCIENCE.

RESULTS

Through the search strategies, 491 articles were found in the databases. After exclusion of duplicates, peer analysis of titles and abstracts, full reading and screening of lists of references, the final sample of studies included was 38 articles. The main harms cited by the publications were as follows: limb ischemia, thrombosis, hemorrhage, accidental removal, inadvertent connection of inadequate infusion solution, pseudoaneurysm and bloodstream infection.

CONCLUSIONS

It was evidenced that patients are subjected to risks of adverse events from the insertion moment to removal of the arterial catheter, focusing on the infusion solution used to fill the circuit, the type of securement and dressings chosen, as well as the Nursing care measures for the prevention of bloodstream infection.

Emergency Management and Nursing Considerations of Carotid Blowout Syndrome

INTRODUCTION

Carotid blowout syndrome is a rare but fatal complication often witnessed secondary to treating patients with head and neck cancer. It occurs when damage and necrosis lead to the carotid artery wall rupture. The symptoms encountered in these patients range from asymptomatic to cardiac arrest. Here, we present 5 cases of carotid blowout syndrome in the emergency department.

CASE PRESENTATIONS

Patients demonstrated symptoms ranging from subtle bleeding to hemodynamic instability, highlighting the diverse nature of carotid blowout syndrome in this population. Notably, while all patients had a history of radiotherapy, some had additional risk factors for carotid blowout syndrome, including prior surgery (n = 2), malnutrition (n = 3), and tracheostomies (n = 2). Definitive diagnoses were established through clinical evaluation and computed tomography angiography. Immediate interventions included bleeding control, resuscitation, and consultations with relevant specialties. Four patients underwent interventional radiology procedures, and 1 patient received otolaryngology care. While 2 patients recovered completely, 1 died in the emergency department, and 1 in the intensive care unit. One patient's clinical course was complicated by a stroke.

CONCLUSION

The approach to the carotid blowout syndrome patient includes complex steps that proceed in a multidisciplinary manner, starting from triage until discharge. Emergency nurses play crucial roles at every stage. They should be aware of carotid blowout syndrome when evaluating patients with head and neck cancer presenting with bleeding. When treating these patients, emergency nurses should be ready for airway interventions, bleeding control, and massive transfusion protocol. In this context, the multifaceted approaches made by nurses contribute significantly to carotid blowout syndrome management in the emergency department.

Chest Intensive Care Unit Imaging: Pearls and Pitfalls

Imaging plays a major role in the care of the intensive care unit (ICU) patients. An understanding of the monitoring devices is essential for the interpretation of imaging studies. An awareness of their expected locations aids in identifying complications in a timely manner. This review describes the imaging of ICU monitoring and support catheters, tubes, and pulmonary and cardiac devices, some more commonly encountered and others that have been introduced into clinical patient care more recently. Special focus will be placed on chest radiography and potential pitfalls encountered.

Patient preferences and willingness to pay for central venous access devices in breast cancer: A multicenter discrete choice experiment

BACKGROUND

Despite being a significant management decision in clinical or nursing practice, there is limited understanding of the preferences regarding risks, benefits, costs, and other attributes of patients with breast cancer when selecting peripherally inserted central catheters or totally implanted ports. The objective of this study is to investigate the preferences of patients with breast cancer who require chemotherapy when selecting an optimal central venous access device.

METHODS

Data on patients' preferences for central venous access devices were collected using a face-to-face discrete choice experiment from the oncology departments of three public hospitals in China representing the eastern (Zhejiang province), central (Henan province), and western (Sichuan province) regions. The study used six attributes to describe the preferences of breast cancer patients for central venous access devices, including out-of-pocket cost, limitations in activities of daily living, catheter maintenance frequency, risk of catheter-related thrombosis, risk of catheter-related infection, and size of incision. Data were analyzed using a conditional logit model and mixed logit model. The marginal willingness to pay (mWTP) was calculated by assessing the ratio of the preference for other attributes to the preference for out-of-pocket cost.

RESULTS

A total of 573 respondents completed the survey. The discrete choice experiment results showed that respondents strongly preferred a central venous access device with a catheter maintenance frequency of one time a month (vs four times a month, β = 1.188, p < 0.001), the lower risk of catheter-related thrombosis (2 % vs 10 %, β = 1.068; p < 0.001) and lower risk of catheter-related infection (2 % vs 8 % risk: β = 0.824; p < 0.001). Respondents were willing to pay CNY ¥11,968.1 (US$1776.5) for a central venous access device with a catheter maintenance frequency of one time a month rather than four times a month, ¥10,753.6 (US$1596.2) for a central venous access device with 2 % thrombosis risk over one with 10 %, and ¥8302.0 (US$1232.3) for a central venous access device with 2 % infection risk over one with 8 %. Respondents with longer travel time to the hospital, younger than 50 years old, and with urban employee basic medical insurance were willing to pay more for an improvement in the attributes.

CONCLUSIONS

These findings suggest that patients with breast cancer were mainly concerned with the out-of-pocket cost, catheter maintenance frequency, risk of catheter-related thrombosis and risk of catheter-related infection when choosing a central venous access device for the delivery of chemotherapy. In clinical or nursing practice, when making central venous access device recommendation for young patients and those who live far from hospitals, totally implanted ports may be a preferable choice.

Artificial Intelligence to Assess Tracheal Tubes and Central Venous Catheters in Chest Radiographs Using an Algorithmic Approach With Adjustable Positioning Definitions

PURPOSE

To develop and validate an artificial intelligence algorithm for the positioning assessment of tracheal tubes (TTs) and central venous catheters (CVCs) in supine chest radiographs (SCXRs) by using an algorithm approach allowing for adjustable definitions of intended device positioning.

MATERIALS AND METHODS

Positioning quality of CVCs and TTs is evaluated by spatially correlating the respective tip positions with anatomical structures. For CVC analysis, a configurable region of interest is defined to approximate the expected region of well-positioned CVC tips from segmentations of anatomical landmarks. The CVC/TT information is estimated by introducing a new multitask neural network architecture for jointly performing type/existence classification, course segmentation, and tip detection. Validation data consisted of 589 SCXRs that have been radiologically annotated for inserted TTs/CVCs, including an experts' categorical positioning assessment (reading 1). In-image positions of algorithm-detected TT/CVC tips could be corrected using a validation software tool (reading 2) that finally allowed for localization accuracy quantification. Algorithmic detection of images with misplaced devices (reading 1 as reference standard) was quantified by receiver operating characteristics.

RESULTS

Supine chest radiographs were correctly classified according to inserted TTs/CVCs in 100%/98% of the cases, thereby with high accuracy in also spatially localizing the medical device tips: corrections less than 3 mm in >86% (TTs) and 77% (CVCs) of the cases. Chest radiographs with malpositioned devices were detected with area under the curves of >0.98 (TTs), >0.96 (CVCs with accidental vessel turnover), and >0.93 (also suboptimal CVC insertion length considered). The receiver operating characteristics limitations regarding CVC assessment were mainly caused by limitations of the applied CXR position definitions (region of interest derived from anatomical landmarks), not by algorithmic spatial detection inaccuracies.

CONCLUSIONS

The TT and CVC tips were accurately localized in SCXRs by the presented algorithms, but triaging applications for CVC positioning assessment still suffer from the vague definition of optimal CXR positioning. Our algorithm, however, allows for an adjustment of these criteria, theoretically enabling them to meet user-specific or patient subgroups requirements. Besides CVC tip analysis, future work should also include specific course analysis for accidental vessel turnover detection.

Central venous catheter tip misplacement: A multicentre cohort study of 8556 thoracocervical central venous catheterisations

BACKGROUND

There is a paucity of data on the incidence of central venous catheter tip misplacements after the implementation of ultrasound guidance during insertion. The aims of the present study were to determine the incidence of tip misplacements and to identify independent variables associated with tip misplacement.

METHODS

All jugular and subclavian central venous catheter insertions in patients ≥16 years with a post-procedural chest radiography at four hospitals were included. Each case was reviewed for relevant catheter data and radiologic evaluations of chest radiographies. Tip misplacements were classified as 'any tip misplacement', 'minor tip misplacement' or 'major tip misplacement'. Multivariable logistic regression analyses were used to investigate associations between predefined independent variables and tip misplacements.

RESULTS

A total of 8556 central venous catheter insertions in 5587 patients were included. Real-time ultrasound guidance was used in 91% of all insertions. Any tip misplacement occurred (95% confidence interval) in 3.7 (3.3-4.1)% of the catheterisations, and 2.1 (1.8-2.4)% were classified as major tip misplacements. The multivariable logistic regression analyses showed that female patient gender, subclavian vein insertions, number of skin punctures and limited operator experience were associated with a higher risk of major tip misplacement, whereas increasing age and height were associated with a lower risk.

CONCLUSIONS

In this large prospective multicentre cohort study, performed in the ultrasound-guided era, we demonstrated the incidence of tip misplacements to be 3.7 (3.3-4.1)%. Right internal jugular vein catheterisation had the lowest incidence of both minor and major tip misplacement.

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.

Operator gender differences in major mechanical complications after central line insertions: a subgroup analysis of a prospective multicentre cohort study

BACKGROUND

A previous study on mechanical complications after central venous catheterisation demonstrated differences in complication rates between male and female operators. The objective of this subgroup analysis was to further investigate these differences. The hypothesis was that differences in distribution of predefined variables between operator genders could be identified.

METHODS

This was a subgroup analysis of a prospective, multicentre, observational cohort study conducted between March 2019 and December 2020 including 8 586 patients ≥ 16 years receiving central venous catheters at four emergency care hospitals. The main outcome measure was major mechanical complications defined as major bleeding, severe cardiac arrhythmia, pneumothorax, arterial catheterisation, and persistent nerve injury. Independent t-test and χ2 test were used to investigate differences in distribution of major mechanical complications and predefined variables between male and female operators. Multivariable logistic regression analysis was used to determine association between operator gender and major mechanical complications.

RESULTS

Female operators had a lower rate of major mechanical complications than male operators (0.4% vs 0.8%, P = .02), were less experienced (P < .001), had more patients with invasive positive pressure ventilation (P < .001), more often chose the internal jugular vein (P < .001) and more frequently used ultrasound guidance (P < .001). Male operators more often chose the subclavian vein (P < .001) and inserted more catheters with bore size ≥ 9 Fr (P < .001). Multivariable logistic regression analysis showed that male operator gender was associated with major mechanical complication (OR 2.67 [95% CI: 1.26-5.64]) after correction for other relevant independent variables.

CONCLUSIONS

The hypothesis was confirmed as differences in distribution of predefined variables between operator genders were found. Despite being less experienced, female operators had a lower rate of major mechanical complications. Furthermore, male operator gender was independently associated with a higher risk of major mechanical complications. Future studies are needed to further investigate differences in risk behaviour between male and female operators.

Feasibility and Safety of a Technique Intended to Place the Catheter Tip in the Right Atrium without Abutment Against the Cardiac Wall during Implantation of the Totally Implantable Venous Access Port

Purpose

To assess the safety and feasibility of intentionally positioning the catheter tip in the right atrium (RA) without an abutment during implantation of a totally implantable venous access port (TIVAP).

Materials and Methods

We enrolled 330 patients who had undergone TIVAP implantation between January and December 2016 and postoperative chest CT. The TIVAP was placed using the single-incision technique to access the axillary vein directly from the incision line. To position the catheter tip in the RA without abutment, blood return was checked before cutting. Catheter length and complications were evaluated by retrospectively reviewing medical images and records.

Results

All patients achieved successful catheter tip positioning without abutment or dysfunction. The median tip position was 15.3 mm distal to the cavoatrial junction (CAJ) on fluoroscopy and 6 mm distal to the CAJ on CT. Catheter tips migrated a median of 10.4 mm cephalically on CT compared to fluoroscopy. Thromboses were detected in the RA and superior vena cava in one patient each.

Conclusion

Intentional catheter tip positioning in the RA without abutment is a safe and feasible technique with a low incidence of thrombosis and no observed dysfunction.

The SIP protocol update: Eight strategies, incorporating Rapid Peripheral Vein Assessment (RaPeVA), to minimize complications associated with peripherally inserted central catheter insertion

Insertion of Peripherally Inserted Central Catheters (PICCs) is potentially associated with the risk of immediate/early adverse events, some of them minimal (repeated punctures) and some relevant (accidental arterial puncture or nerve-related injury). Several strategies adopted during the insertion process may minimize the risk of such events, including late complication risks such as infection, venous thrombosis, or catheter dislodgment and/or malposition. This paper describes an update version of the SIP protocol (Safe Insertion of PICCs), an insertion bundle which includes eight effective strategies that aims to minimize immediate, early, or late insertion-associated complications. These strategies include: preprocedural ultrasound assessment utilizing the RaPeVA (Rapid Peripheral Venous Assessment) protocol; appropriate skin antiseptic technique; choice of appropriate vein, adoption of the Zone Insertion Method™; clear identification of the median nerve and brachial artery; ultrasound-guided puncture; ultrasound-guided tip navigation; intra-procedural assessment of tip location; correct securement of the catheter, and appropriate protection of the exit site. This updated version of the SIP protocol includes several novelties based on the most recent evidence-based scientific literature on PICC insertion, such as the clinical relevance of the tunneling technique, the use of ultrasound for intra-procedural tip navigation and tip location, and the new technologies for the protection of the exit site (cyanoacrylate glue) and for the securement of the catheter (subcutaneous anchorage).

Ultrasound-guided subclavian vein catheterisation with a needle guide (ELUSIVE): protocol for a randomised controlled study

INTRODUCTION

Central venous catheters are indispensable in modern healthcare. Unfortunately, they are accompanied by minor as well as major complications, leading to increased morbidity, mortality and costs. Immediate insertion-related complications (mechanical complications) have decreased due to the implementation of real-time ultrasound guidance, but they still occur and additional efforts to enhance patient safety are warranted. This study aims to investigate whether the use of a needle guide mounted on the ultrasound probe in subclavian catheterisations may decrease the number of catheterisations with >1 skin puncture (primary outcome).

METHODS AND ANALYSIS

This is an investigator-initiated, non-commercial, randomised, controlled, parallel-group study conducted at Skåne University Hospital, Lund, Sweden. Adults (≥18 years) with a clinical indication for a subclavian central venous catheter and the ability to give written informed consent will be eligible for inclusion. Exclusion criteria include subclavian catheterisation deemed unsuitable based on the preprocedural ultrasound examination. Patients will be randomised to catheterisation by certified operators using a microconvex probe (long-axis, in-plane technique) with (n=150) or without (n=150) a needle guide. The ultrasound imaging from the procedures will be recorded and assessed by two reviewers individually. The assessors will be blinded for group affiliation. Secondary outcomes include the total number of skin punctures, mechanical complications, time to successful venous puncture, number of failed catheterisations and operator satisfaction with the needle guide at the end of the study period.Recruitment started on 8 November 2022 and will continue until the sample size is achieved.

ETHICS AND DISSEMINATION

This study was approved by the Swedish Ethical Review Authority (#2022-04073-01) and the Swedish Medical Products Agency (#5.1-2022-52130; CIV-21-12-038367). The findings will be submitted to an international peer-reviewed journal.

Intra-pocket ultrasound-guided axillary vein puncture vs. cephalic vein cutdown for cardiac electronic device implantation: the ACCESS trial

BACKGROUND AND AIMS

Intra-pocket ultrasound-guided axillary vein puncture (IPUS-AVP) for venous access in implantation of transvenous cardiac implantable electronic devices (CIED) is uncommon due to the lack of clinical evidence supporting this technique. This study investigated the efficacy and early complications of IPUS-AVP compared to the standard method using cephalic vein cutdown (CVC) for CIED implantation.

METHODS

ACCESS was an investigator-led, interventional, randomized (1:1 ratio), monocentric, controlled superiority trial. A total of 200 patients undergoing CIED implantation were randomized to IPUS-AVP (n = 101) or CVC (n = 99) as a first assigned route. The primary endpoint was the success rate of insertion of all leads using the first assigned venous access technique. The secondary endpoints were time to venous access, total procedure duration, fluoroscopy time, X-ray exposure, and complications. Complications were monitored during a follow-up period of three months after procedure.

RESULTS

IPUS-AVP was significantly superior to CVC for the primary endpoint with 100 (99.0%) vs. 86 (86.9%) procedural successes (P = .001). Cephalic vein cutdown followed by subclavian vein puncture was successful in a total of 95 (96.0%) patients, P = .21 vs. IPUS-AVP. All secondary endpoints were also significantly improved in the IPUS-AVP group with reduction in time to venous access [3.4 vs. 10.6 min, geometric mean ratio (GMR) 0.32 (95% confidence interval, CI, 0.28-0.36), P < .001], total procedure duration [33.8 vs. 46.9 min, GMR 0.72 (95% CI 0.67-0.78), P < .001], fluoroscopy time [2.4 vs. 3.3 min, GMR 0.74 (95% CI 0.63-0.86), P < .001], and X-ray exposure [1083 vs. 1423 mGy.cm², GMR 0.76 (95% CI 0.62-0.93), P = .009]. There was no significant difference in complication rates between groups (P = .68).

CONCLUSIONS

IPUS-AVP is superior to CVC in terms of success rate, time to venous access, procedure duration, and radiation exposure. Complication rates were similar between the two groups. Intra-pocket ultrasound-guided axillary vein puncture should be a recommended venous access technique for CIED implantation.

Single-plane versus real-time biplane approaches for ultrasound-guided central venous catheterization in critical care patients: a randomized controlled trial

BACKGROUND

Critical care patients often require central venous cannulation (CVC). We hypothesized that real-time biplane ultrasound-guided CVC would improve first-puncture success rate and reduce mechanical complications. The purpose of this study was to compare the success rate and safety of single-plane and real-time biplane approaches for ultrasound-guided CVC.

METHODS

From October 2022 to March 2023, 256 participants with critical illness requiring CVC were randomized to either the single-plane (n = 128) or biplane (n = 128) ultrasound-guided cannulation groups. The success rate, number of punctures, procedure duration, incidence of catheterization-related complications, and confidence score of operators were documented.

RESULTS

The central vein was successfully cannulated in all 256 participants (163 [64%] man and 93 [36%] women; mean age 69 ± 19 [range 13-104 years]), including 182 and 74 who underwent internal jugular vein cannulation (IJVC) and femoral vein cannulation (FVC), respectively. The incidence of successful puncture on the first attempt was higher in the biplane group than that in the single-plane group (91.6% vs. 74.7%; relative risk (RR), 1.226; 95% confidence interval (CI), 1.069-1.405; P = 0.002 for the IJVC and 90.9% vs. 68.3%; RR, 1.331; 95% CI, 1.053-1.684; P = 0.019 for the FVC). The biplane group was also associated with a higher first-puncture single-pass catheterization success rate (87.4% vs. 69.0% and 90.9% vs. 68.3%), fewer undesired punctures (1[1-1(1-2)] vs. 1[1-2(1-4)] and 1[1-1(1-3)] vs. 1[1-2(1-4)]), shorter cannulation time (205 s [162-283 (66-1,526)] vs. 311 s [243-401 (136-1,223)] and 228 s [193-306 (66-1,669)] vs. 340 s [246-499 (130-944)]), and fewer immediate complications (10.5% vs. 28.7% and 9.1% vs. 34.1%) for both IJVC and FVC (all P < 0.05).

CONCLUSION

Real-time biplane imaging of ultrasound-guided CVCs offers advantages over the single-plane approach for critically ill patients.

Ultrasound-guided PIVC insertion: a randomised controlled trial protocol

Ultrasound-guided insertion of peripheral intravenous catheters (PIVCs) is an alternative to traditional anatomical landmark-based insertion. However, data on its performance in paediatric patients of varying levels of difficult intravenous access are limited. The researchers hypothesise that ultrasound-guided PIVC insertion will increase first-attempt success compared with landmark technique. This randomised, parallel-group, single-centre, superiority trial commenced recruiting in July 2021, including hospitalised children (aged 0 (>37 weeks gestation) to 18 years) requiring a PIVC. It will recruit 180 children, stratified by degree of perceived difficulty, and centrally randomised into two groups (ratio 1:1). The primary outcome is first-attempt PIVC insertion success. Secondary outcomes include total number of PIVC insertion attempts, PIVC insertion failure, post-insertion complications, dwell time, patient/parent satisfaction, and healthcare costs. The current study will inform the superiority of ultrasound-guided PIVC insertion in comparison with landmark technique. Adoption by healthcare facilities might improve patient outcomes and decrease healthcare costs.

The SIF protocol: A seven-step strategy to minimize complications potentially related to the insertion of femorally inserted central catheters

The insertion of central venous catheters through the femoral veins is not uncommon and is potentially associated with the risk of immediate puncture-related complications and severe late complications as infection and thrombosis. As for other central venous access devices, the use of a standardized protocol of insertion and the correct application of evidence-based strategies are beneficial in reducing the risk of complications. We proposed a standardized protocol (S.I.F.: Safe Insertion of Femorally Inserted Central Catheters) consisting of seven strategies that should be part of vascular cannulation and should be adopted during the insertion of femoral venous catheters, aiming to minimize immediate, early and late insertion-related complications. These strategies include: preprocedural evaluation of the patient history and of the veins, appropriate aseptic technique, ultrasound guided puncture and cannulation of the vein, intra-procedural assessment of the tip position, adequate protection of the exit site, proper securement of the catheter, and appropriate coverage of the exit site.

A scoping review of Clinical Studies, Hospital Group Reports and National Strategic Documents on vascular access devices in cancer patients

INTRODUCTION

The extent of vascular/venous access device (VAD) research output from the Island of Ireland is unknown. The identification of the papers available is important to create a future research agenda.

OBJECTIVES

The main objective of this study is to answer three questions: What is the number and descriptive quality of reported Vascular Access Device literature from the Island of Ireland? Is the reporting of Catheter Related Infection rates for cancer patients common in Irish Hospital Groups, National Cancer Reports and Publication Outputs? What are the implications for future research in this area?

METHODS

We used a scoping review and searched selected databases, grey literature and hospital regulatory bodies websites following the Joanna Briggs Institute Guidelines 2017. A data charting form was developed based on a template from the Joanna Briggs Institute and this was used to extract data from the included reports.

RESULTS

A total of 660 reports were screened. Sixty-one full text articles were reviewed from which 20 reports were included for data extraction. Of the reports included the following designs were used: nine retrospective study designs, four guidelines, two prospective study designs, two literature reviews and one of the following; survey, case study and cross sectional analysis designs. We did not identify any randomised controlled trials, systematic reviews, meta-analysis, meta-synthesis and scoping reviews. Five studies included catheter related infection rates. Gaps in the research include the collection of data sets and the need to establish a VAD registry; develop core outcomes for VADs; assessment and evaluation of VAD care bundles among cancer patients; and, the inclusion of public and patient involvement in future VAD research.

CONCLUSION

The reporting of VAD outcomes in published literature regarding cancer patients receiving treatment in Ireland is inconsistent and varied with no interventional studies addressing vascular access complications in cancer care.

Implementation of modified Seldinger technology for percutaneous catheterization in critically ill newborns

OBJECTIVE

To describe the implementation of Modified Seldinger Technology for percutaneous catheterization in critically ill newborns.

METHOD

A quasi-experimental before- and-after study, carried out with neonatologist nurses in a Neonatal Intensive Care Unit.

RESULTS

Seven nurses participated in the research. Catheter pre-insertion, insertion and maintenance were assessed using the conventional and modified Seldinger technique. Reliability was satisfactory in pre-test, 5.40 (Md = 6.00), and post-test, 5.94 (Md = 7.00), and perfect in the items about device insertion and maintenance. There was low assertiveness in the items on indication, microintroduction procedure via ultrasound, limb repositioning and disinfection of connections/connectors.

CONCLUSION

Despite the Modified Seldinger Technique expanding some stages of execution over the traditional method of percutaneous catheterization, nurses were more assertive after theoretical-practical training. The technology was implemented and is in the process of being implemented in the health service.

Improving difficult peripheral intravenous access requires thought, training and technology (DART3): a stepped-wedge, cluster randomised controlled trial protocol

BACKGROUND

Peripheral intravenous catheters (PIVCs) are the most used invasive medical device in healthcare. Yet around half of insertion attempts are unsuccessful leading to delayed medical treatments and patient discomfort of harm. Ultrasound-guided PIVC (USGPIVC) insertion is an evidence-based intervention shown to improve insertion success especially in patients with Difficult IntraVenous Access (BMC Health Serv Res 22:220, 2022), however the implementation in some healthcare settings remains suboptimal. This study aims to co-design interventions that optimise ultrasound guided PIVC insertion in patients with DIVA, implement and evaluate these initiatives and develop scale up activities.

METHODS

A stepped-wedge cluster randomized controlled trial will be conducted in three hospitals (two adult, one paediatric) in Queensland, Australia. The intervention will be rolled out across 12 distinct clusters (four per hospital). Intervention development will be guided by Michie's Behavior Change Wheel with the aim to increase local staff capability, opportunity, and motivation for appropriate, sustainable adoption of USGPIVC insertion. Eligible clusters include all wards or departments where > 10 PIVCs/week are typically inserted. All clusters will commence in the control (baseline) phase, then, one cluster per hospital will step up every two months, as feasible, to the implementation phase, where the intervention will be rolled out. Implementation strategies are tailored for each hospital by local investigators and advisory groups, through context assessments, staff surveys, and stakeholder interviews and informed by extensive consumer interviews and consultation. Outcome measures align with the RE-AIM framework including clinical-effectiveness outcomes (e.g., first-time PIVC insertion success for DIVA patients [primary outcome], number of insertion attempts); implementation outcomes (e.g., intervention fidelity, readiness assessment) and cost effectiveness outcomes. The Consolidated Framework for Implementation Research framework will be used to report the intervention as it was implemented; how people participated in and responded to the intervention; contextual influences and how the theory underpinning the intervention was realised and delivered at each site. A sustainability assessment will be undertaken at three- and six-months post intervention.

DISCUSSION

Study findings will help define systematic solutions to implement DIVA identification and escalation tools aiming to address consumer dissatisfaction with current PIVC insertion practices. Such actionable knowledge is critical for implementation of scale-up activities.

Central venous stenosis after subclavian versus internal jugular dialysis catheter insertion (CITES) in adults in need of a temporary central dialysis catheter: study protocol for a two-arm, parallel-group, non-inferiority randomised controlled trial

BACKGROUND

The right internal jugular vein is currently recommended for temporary central dialysis catheters (tCDC) based on results from previous studies showing a lower incidence of central vein stenosis compared to the subclavian vein. Data is however conflicting, and there are several advantages when the subclavian route is used for tCDCs. This prospective, controlled, randomised, non-inferiority study aims to compare the incidence of post-catheterisation central vein stenosis between the right subclavian and the right internal jugular routes.

METHODS

Adult patients needing a tCDC will be included from several hospitals and randomised to either subclavian or internal jugular vein catheterisation with a silicone tCDC. Inclusion continues until 50 patients in each group have undergone a follow-up CT venography. The primary outcome is the incidence of post-catheterisation central vein stenosis detected by a CT venography performed 1.5 to 3 months after removal of the tCDC. Secondary outcomes include between-group comparisons of (I) the patients' experience of discomfort and pain, (II) any dysfunction of the tCDC during use, (III) catheterisation success rate and (IV) the number of mechanical complications. Furthermore, the ability to detect central vein stenosis by a focused ultrasound examination will be evaluated using the CT venography as golden standard.

DISCUSSION

The use of the subclavian route for tCDC placement has largely been abandoned due to older studies with various methodological issues. However, the subclavian route offers several advantages for the patient. This trial is designed to provide robust data on the incidence of central vein stenosis after silicone tCDC insertion in the era of ultrasound-guided catheterisations.

Perioperative anaphylactic reactions to central venous and pulmonary artery catheters containing chlorhexidine, sulfadiazine, or latex: a historical cohort study

PURPOSE

Central venous catheters (CVCs) and pulmonary artery catheters (PACs) containing chlorhexidine, silver sulfadiazine, or latex can cause perioperative anaphylaxis. We examined the incidence of and outcomes associated with anaphylaxis caused by CVCs/PACs.

METHODS

In a historical cohort study, we retrospectively identified adult patients fitted with CVCs/PACs at the Mayo Clinics in Minnesota, Arizona, and Florida from 1 January 2008 to 1 March 2018. Potential and confirmed cases of perioperative anaphylactic reactions were individually reviewed and classified.

RESULTS

During the study period, 39,505 procedures were performed during which CVCs/PACs were inserted. Of these, 2,937 patients with pre-existing chlorhexidine, sulfonamide (sulfa), and/or latex allergies had CVCs/PACs inserted that contained these substances. Perioperative anaphylaxis, in which CVCs/PACs were the confirmed or potential causative agent, occurred during 53 procedures. Seven patients had a preoperatively reported sulfa or latex allergy; no patients had a preoperative chlorhexidine allergy. Six of the seven patients with reported allergies to sulfa or latex had a CVC/PAC inserted that contained these substances. Twenty-four patients with anaphylaxis had postoperative allergic disease consultation; ten of these (42%) underwent skin testing.

CONCLUSION

Perioperative anaphylactic reactions related to CVCs/PACs containing chlorhexidine, silver sulfadiazine, or latex were rare in this large historical cohort study. We identified 2,937 patients with pre-existing chlorhexidine, sulfa, and/or latex allergies and had CVCs/PACs inserted that contained these substances. Although few cases of perioperative anaphylaxis attributable to these substances were observed in patients with corresponding allergies, the potential for substantial complication exists. Providers should be aware of the potential for these hidden exposures.

The Adult Difficult Intravenous Access (DIVA) Cognitive Aid: An Evidence-Based Cognitive Aid Prototype for Difficult Peripheral Venous Access

Difficult intravenous access (DIVA) is common, with imperfect solutions. Cognitive aids are widespread in anaesthesia; however, a standard DIVA cognitive aid is lacking. This article describes a cognitive aid for DIVA. It has been developed using evidence-based techniques for DIVA. The effects of heuristics, biases, and automatic thinking on procedural decision-making are briefly discussed. While often useful, shortcut decision-making can impair the performance of apparently simple tasks. Cognitive aids may lead to better outcomes by providing choice architecture. This resource is intended as a cognitive aid prototype for difficult peripheral venous access, incorporating both modern behavioural psychology principles and evidence-based medicine. It may be used as both an educational tool, or as a cognitive aid to assist in situations where DIVA is encountered or expected. The adult DIVA cognitive aid is intended for use in both elective and emergency scenarios by practitioners adequately trained in ultrasound-guided or ultrasound-assisted vascular access and Seldinger-based techniques. Clinical implementation and audit of the adult DIVA cognitive aid, or similar locally developed cognitive aids based on this prototype are recommended.

The SIC protocol: A seven-step strategy to minimize complications potentially related to the insertion of centrally inserted central catheters

Insertion of central venous catheters in the cervico-thoracic area is potentially associated with the risk of immediate/early untoward events, some of them negligible (repeated punctures), some relevant (accidental arterial puncture), and some severe (pneumothorax). Furthermore, different strategies adopted during insertion may reduce or increase the incidence of late catheter-related complications (infection, venous thrombosis, dislodgment). This paper describes a standardized protocol (S.I.C.: Safe Insertion of Centrally Inserted Central Catheters) for the systematic application of seven basic beneficial strategies to be adopted during insertion of central venous catheters in the cervico-thoracic region, aiming to minimize immediate, early, or late insertion-related complications. These strategies include: preprocedural evaluation, appropriate aseptic technique, ultrasound guided insertion, intra-procedural assessment of the tip position, adequate protection of the exit site, proper securement of the catheter, and adequate coverage of the exit site.

Ultrasound-Guided Infraclavicular Axillary Vein Versus Internal Jugular Vein Cannulation in Critically Ill Mechanically Ventilated Patients: A Randomized Trial

OBJECTIVES

This clinical trial aimed to compare the ultrasound-guided in-plane infraclavicular cannulation of the axillary vein (AXV) and the ultrasound-guided out-of-plane cannulation of the internal jugular vein (IJV).

DESIGN

A prospective, single-blinded, open label, parallel-group, randomized trial.

SETTING

Two university-affiliated ICUs in Poland (Opole and Lublin).

PATIENTS

Mechanically ventilated intensive care patients with clinical indications for central venous line placement.

INTERVENTIONS

Patients were randomly assigned into two groups: the IJV group ( n = 304) and AXV group ( n = 306). The primary outcome was to compare the IJV group and AXV group through the venipuncture and catheterization success rates. Secondary outcomes were catheter tip malposition and early mechanical complication rates. All catheterizations were performed by advanced residents and consultants in anesthesiology and intensive care.

MEASUREMENTS AND MAIN RESULTS

The IJV puncture rate was 100%, and the AXV was 99.7% (chi-square, p = 0.19). The catheterization success rate in the IJV group was 98.7% and 96.7% in the AXV group (chi-square, p = 0.11). The catheter tip malposition rate was 9.9% in the IJV group and 10.1% in the AXV group (chi-square, p = 0.67). The early mechanical complication rate in the IJV group was 3% (common carotid artery puncture-4 cases, perivascular hematoma-2 cases, vertebral artery puncture-1 case, pneumothorax-1 case) and 2.6% in the AXV group (axillary artery puncture-4 cases, perivascular hematoma-4 cases) (chi-square, p = 0.79).

CONCLUSIONS

No difference was found between the real-time ultrasound-guided out-of-plane cannulation of the IJV and the infraclavicular real-time ultrasound-guided in-plane cannulation of the AXV. Both techniques are equally efficient and safe in mechanically ventilated critically ill patients.

European recommendations on the proper indication and use of peripheral venous access devices (the ERPIUP consensus): A WoCoVA project

Since several innovations have recently changed the criteria of choice and management of peripheral venous access (new devices, new techniques of insertion, new recommendations for maintenance), the WoCoVA Foundation (WoCoVA = World Conference on Vascular Access) has developed an international Consensus with the following objectives: to propose a clear and useful classification of the currently available peripheral venous access devices; to clarify the proper indication of central versus peripheral venous access; discuss the indications of the different peripheral venous access devices (short peripheral cannulas vs long peripheral cannulas vs midline catheters); to define the proper techniques of insertion and maintenance that should be recommended today. To achieve these purposes, WoCoVA have decided to adopt a European point of view, considering some relevant differences of terminology between North America and Europe in this area of venous access and the need for a common basis of understanding among the experts recruited for this project. The ERPIUP Consensus (ERPIUP = European Recommendations for Proper Indication and Use of Peripheral venous access) was designed to offer systematic recommendations for clinical practice, covering every aspect of management of peripheral venous access devices in the adult patient: indication, insertion, maintenance, prevention and treatment of complications, removal. Also, our purpose was to improve the standardization of the terminology, bringing clarity of definition, and classification.

Echocardiography and Ultrasound Committee statement for the accreditation programme in point-of-care ultrasonography in Poland

Ultrasonography is becoming an essential part of the management of critically ill patients. There has been a sufficient body of evidence to support the incorporation of point-of-care ultrasound (POCUS) in anaesthesia and intensive care medicine training programme. Recently the European Society of Intensive Care Medicine reco-gnized POCUS as an essential skill for European Intensive Care Medicine specialists and updated Competency Based Training in Intensive Care (CoBaTrICe). Following European training standards, the Ultrasound and Echocardiography Committee of the Polish Society of Anaesthesiology and Intensive Therapy issued this Position Statement for recommendations for the accreditation process in POCUS in Poland.

Paediatric intensive care 'do not do' recommendations in Spain: Selection by Delphi method

INTRODUCTION

Health care is not free of ineffective, unsafe or inefficient diagnostic and therapeutic practices. To address this, different scientific societies and health authorities have proposed 'do not do' recommendations (DNDRs). Our goal was the selection by consensus of a set of DNDRs for paediatric intensive care in Spain.

MATERIAL AND METHOD

The research was carried out in 2 phases: first, gathering potential DNDRs; second, selecting the most important ones, using the Delphi method, based on the prevalence of the practice to be modified, the severity of its potential risks and the ease with which it could be modified. Proposals and evaluations were both made by members of working groups of the Sociedad Española de Cuidados Intensivos Pediátricos (SECIP, Spanish Society of Paediatric Intensive Care), coordinated by email. The initial set of DNDRs was reduced based on the coefficient of variation (<80%) of the corresponding evaluations.

RESULTS

A total of 182 DNDRs were proposed by 30 intensivists. The 14 Delphi evaluators managed to pare down the initial set to 85 DNDRs and, after a second round, to the final set of 26 DNDRs. The care quality dimensions most represented in the final set are clinical effectiveness and patient safety.

CONCLUSIONS

This study allowed the selection by consensus of a series of recommendations to avoid unsafe, inefficient or ineffective practices in paediatric intensive care in Spain, which could be useful for improving the quality of clinical care in our field.

Central catheter tip migration in critically ill patients

OBJECTIVES

Chest X-ray (CXR) is routinely required for assessing Central Venous Catheter (CVC) tip position after insertion, but there is limited data as to the movement of the tip location during hospitalization. We aimed to assess the migration of Central Venous Catheter (CVC) position, as a significant movement of catheter tip location may challenge some of the daily practice after insertion.

DESIGN AND SETTINGS

Retrospective, single-center study, conducted in the Intensive Care and Cardiovascular Intensive Care Units in Tel Aviv Sourasky Medical Center 'Ichilov', Israel, between January and June 2019.

PATIENTS

We identified 101 patients with a CVC in the Right Internal Jugular (RIJ) with at least two CXRs during hospitalization.

MEASUREMENTS AND RESULTS

For each patient, we measured the CVC tip position below the carina level in the first and all consecutive CXRs. The average initial tip position was 1.52 (±1.9) cm (mean±SD) below the carina. The maximal migration distance from the initial insertion position was 1.9 (±1) cm (mean±SD). During follow-up of 2 to 5 days, 92% of all subject's CVCs remained within the range of the Superior Vena Cava to the top of the right atrium, regardless of the initial positioning.

CONCLUSIONS

CVC tip position can migrate significantly during a patient's early hospitalization period regardless of primary location, although for most patients it will remain within a wide range of the top of the right atrium and the middle of the Superior Vena Cava (SVC), if accepted as well-positioned.

Review article: Peripheral intravenous catheter insertion in adult patients with difficult intravenous access: A systematic review of assessment instruments, clinical practice guidelines and escalation pathways

The optimal approach for peripheral intravenous catheter (PIVC) insertion in adult hospitalised patients with difficult intravenous access (DIVA) is unknown. The present study aimed to critically appraise the quality of (i) assessment instruments and (ii) clinical practice guidelines (CPGs) or escalation pathways for identifying and managing patients with DIVA. Cochrane Central Register of Controlled Trials, EBSCO MEDLINE, EMBASE (OVID) and EBSCO CINAHL databases were searched on 22 March 2021. Studies describing a DIVA assessment measure, CPG or escalation pathway for PIVC insertion in adults (≥18 years of age) were included. Data were extracted using a standardised data extraction form including study design, type of resource and reported clinical outcomes. Quality of DIVA assessment instruments were reviewed using the COnsensus-based Standards for the selection of health Measurement Instruments checklist. Methodological quality of CPGs and escalation pathways was assessed using the Appraisal of Guidelines for Research and Evaluation-II (AGREE-II) instrument. Overall, 24 DIVA resources comprising 16 DIVA assessment instruments and nine CPGs or escalation pathways (including one combined assessment instrument and escalation pathway) were identified. Instruments commonly focused on vein visibility and palpability as indicators of DIVA. CPGs and escalation pathways unanimously recommended use of vessel visualisation technology for patients with or suspected of DIVA. Methodological quality of the resources was mixed. Consensus and standardisation of resources to identify DIVA and recommendations for managing patients with DIVA is limited. Adopting consistent, evidence-based CPGs, escalation pathways or DIVA assessment instruments may significantly improve clinical outcomes.

Central Venous Access and the Risk for Thromboembolic Events in Patients Undergoing Neoadjuvant Chemotherapy and Radical Cystectomy for Muscle-Invasive Bladder Cancer

Thromboembolic events (TEE) are high-risk complications in patients undergoing neoadjuvant chemotherapy (NAC) and radical cystectomy (RC) for urothelial muscle-invasive bladder cancer (MIBC). The purpose of the study was to investigate any differences in TEE-incidence, comparing peripherally inserted central catheter (PICC) versus a totally implanted port (PORT) as CVA (central venous access) during NAC. We identified 947 cystectomized MIBC-patients from four Swedish medical centers in 2009-2021. Inclusion criteria were cT2-T4aN0M0 and 375 patients were finally eligible and evaluated, divided into: NAC-administered (n = 283) resp. NAC-naïve-NAC-eligible (n = 92), the latter as tentative control group. Data on TEEs and types of CVA were retrospectively collected and individually validated, from final transurethral resection of the bladder tumor (TUR-B) to 30 days post-RC. Adjusted logistic regression and log rank test were used for statistical analyses. Amongst NAC-administered, 83% (n = 235) received PICCs and 15% (n = 42) PORTs. Preoperative TEEs occurred in 38 PICC-patients (16.2%) and in one PORT-patient (2.4%), with 47 individual events registered. We found a significantly increased odds ratio of TEE in NAC-administered PICC-patients compared to in PORT-patients (OR: 8.140, p-value: 0.042, 95% CI 1.078-61.455). Our findings indicate a greater risk for pre-RC TEEs with PICCs than with PORTs, suggesting favoring the usage of PORTs for MIBC-NAC-patients.

Preoperative prediction of the need for arterial and central venous catheterization using machine learning techniques

Some surgical patients require an arterial or central venous catheterization intraoperatively. This decision relied solely on the experience of individual anesthesiologists; however, these decisions are not easy for clinicians who are in an emergency or inexperienced. Therefore, applying recent artificial intelligence techniques to automatically extractable data from electronic medical record (EMR) could create a very clinically useful model in this situation. This study aimed to develop a model that is easy to apply in real clinical settings by implementing a prediction model for the preoperative decision to insert an arterial and central venous catheter and that can be automatically linked to the EMR. We collected and retrospectively analyzed data from 66,522 patients, > 18 years of age, who underwent non-cardiac surgeries from March 2019 to April 2021 at the single tertiary medical center. Data included demographics, pre-operative laboratory tests, surgical information, and catheterization information. When compared with other machine learning methods, the DNN model showed the best predictive performance in terms of the area under receiver operating characteristic curve and area under the precision-recall curve. Operation code information accounted for the largest portion of the prediction. This can be applied to clinical fields using operation code and minimal preoperative clinical information.

Peripheral intravenous catheter insertion and use of ultrasound in patients with difficult intravenous access: Australian patient and practitioner perspectives to inform future implementation strategies

Objective

To understand healthcare worker and patient experience with peripheral intravenous catheter (PIVC) insertion in patients with difficult intravenous access (DIVA) including the use of ultrasound (US).

Methods

Descriptive study using 1-on-1 semi-structured interviews conducted between August 2020 and January 2021. Purposeful sampling was used to recruit healthcare practitioners (HCPs) and patients with DIVA who had PIVC experience. Data were analysed using inductive thematic analysis. Interview data were than mapped to the implementation theory Behaviour Change Wheel to inform implementation strategies.

Results

In total 78 interviews (13 patients; 65 HCPs) were completed with respondents from metropolitan (60%), regional (25%) and rural/remote (15%) settings across Australia. Thematic analysis revealed 4 major themes: i) Harmful patient experiences persist, with patient insights not leveraged to effect change; ii) ‘Escalation’ is just a word on the front lines; iii) Heightened risk of insertion failure without resources and training; and iv) Paving the way forward–‘measures need to be in place to prevent failed insertion attempts. Themes were mapped to the behaviour change wheel and implementation strategies developed, these included: staff education, e-health record for DIVA identification, DIVA standard of care and DIVA guidelines to support escalation and ultrasound use.

Conclusion(s)

DIVA patients continue to have poor healthcare experiences with PIVC insertion. There is poor standardisation of DIVA assessment, escalation, US use and clinician education across hospitals. Quality, safety, and education improvement opportunities exist to improve the patient with DIVA experience and prevent traumatic insertions. We identified a number of implementation strategies to support future ultrasound and DIVA pathway implementation.

Comparison of ultrasound-guided peripheral intravenous catheter insertion with landmark technique in paediatric patients: A systematic review and meta-analysis

BACKGROUND

Paediatric peripheral intravenous catheter (PIVC) insertion using traditional landmark insertion technique can be difficult.

AIM

To systematically review the evidence comparing landmark to ultrasound guidance for PIVC insertion in general paediatric patients.

STUDY DESIGN

Cochrane methodology to systematically search for randomised controlled trials comparing landmark to ultrasound-guided PIVC insertion.

DATA SOURCES

Cochrane Central Register of Controlled Trials, US National Library of Medicine, Cumulative Index to Nursing and Allied Health, Embase.

DATA EXTRACTION

English-language, paediatric trials published after 2000, reporting first-attempt insertion success, overall PIVC insertion success, and/or time to insert were included. Central venous, non-venous and trials including only difficult intravenous access were excluded. Data were independently extracted and critiqued for quality using GRADE by three authors, and analysed using random effects, with results expressed as risk ratios (RR), mean differences (MD) and 95% confidence intervals (CI). Registration (CRD42020175314).

RESULTS

Of 70 titles identified, 5 studies (995 patients; 949 PIVCs) were included. There was no evidence of an effect of ultrasound guidance, compared to landmark, for first-attempt insertion success (RR 1.27; 95% CI 0.90-1.78; I2  = 88%; moderate quality evidence), overall insertion success (RR 1.14; 95% CI 0.90-1.44; I2  = 82%; low quality evidence), or time to insertion (mean difference -3.03 min; 95% CI -12.73 to 6.67; I2  = 92%; low quality evidence).

LIMITATIONS

Small sample sizes, inconsistent outcomes and definitions in primary studies precluded definitive conclusions.

CONCLUSIONS

Large clinical trials are needed to explore the effectiveness of ultrasound guidance for PIVC insertion in paediatrics. Specifically, children with difficult intravenous access might benefit most from this technology.

[Application of ultrasound-guided central venous catheterization at various sites in infants with shock]

OBJECTIVES

To study the clinical characteristics of ultrasound-guided central venous catheterization at various sites in infants with shock, and to explore how to quickly select the site for central venous puncture in infants with shock.

METHODS

The medical data of 112 infants who were diagnosed with shock and underwent central venous catheterization in the Pediatric Intensive Care Unit, Dongguan Children's Hospital Affiliated to Guangdong Medical University, from January 2016 to December 2020 were reviewed retrospectively. The patients were divided into an ultrasound group (n=70) and a body surface location group (n=42) according to whether the catheterization was carried out under ultrasound guidance. The application of ultrasound-guided catheterization at various sites in infants was summarized and analyzed, and the success rate of one-time puncture, overall success rate, catheterization time, and complications were compared between these sites.

RESULTS

Compared with the body surface location group, the ultrasound group had a significantly higher success rate of one-time puncture, a significantly shorter catheterization time, and a significantly reduced incidence rate of complications in internal jugular vein and femoral vein catheterizations (P<0.05). In the ultrasound group, the proportion of internal jugular vein catheterization was the highest (51%, 36/70), followed by femoral vein catheterization (33%, 23/70), and subclavian vein catheterization (16%, 11/70). For the comparison between different puncture sites under ultrasound guidance, internal jugular vein catheterization showed the shortest time of a successful catheterization [5.5 (5.0, 6.5) minutes] (P<0.05). There was no significant difference in the incidence rate of complications among the different puncture sites groups (P>0.05).

CONCLUSIONS

In infants with shock, ultrasound-guided internal jugular vein catheterization can be used as the preferred catheterization method for clinicians.

Management of antithrombotic treatment and bleeding disorders in patients requiring venous access devices: A systematic review and a GAVeCeLT consensus statement

Insertion of venous access devices (VAD) is usually considered a procedure with low risk of bleeding. Nonetheless, insertion of some devices is invasive enough to be associated with bleeding, especially in patients with previous coagulopathy or in treatment with antithrombotic drugs for cardiovascular disease. The current practices of platelet/plasma transfusion in coagulopathic patients and of temporary suspension of the antithrombotic treatment before VAD insertion are based on local policies and are often inadequately supported by evidence, since many of the clinical studies on this topic are not recent and are not of high quality. Furthermore, the protocols of antithrombotic treatment have changed during the last decade, after the introduction of new oral anticoagulant drugs. Though some guidelines address some of these issues in relation with specific procedures (port insertion, etc.), no evidence-based document covering all the aspects of this clinical problem is currently available. Thus, the Italian Group of Venous Access Devices (GAVeCeLT) has decided to develop a consensus on the management of antithrombotic treatment and bleeding disorders in patients requiring VADs. After a systematic review of the available evidence, the panel of the consensus (which included vascular access specialists, surgeons, intensivists, anesthetists, cardiologists, vascular medicine experts, nephrologists, infective disease specialists, and thrombotic disease specialists) has structured the final recommendations as detailed answers to three sets of questions: (1) which is an appropriate classification of VAD-related procedures based on the specific bleeding risk? (2) Which is the appropriate management of the patient with bleeding disorders candidate to VAD insertion/removal? (3) Which is the appropriate management of the patient on antithrombotic treatment candidate to VAD insertion/removal? Only statements reaching a complete agreement were included in the final recommendations, and all recommendations were offered in a clear and synthetic list, so to be easily translated into clinical practice.

Retrospective Assessment of Patient and Catheter Characteristics Associated With Malpositioned Central Venous Catheters in Pediatric Patients

OBJECTIVES

The primary objective was to determine the prevalence and characteristics associated with malpositioned temporary, nontunneled central venous catheters (CVCs) placed via the internal jugular (IJ) and subclavian (SC) veins in pediatric patients.

DESIGN

Single-center retrospective cohort study.

SETTING

Quaternary academic PICU.

PATIENTS

Children greater than 1 month to less than 18 years who had a CVC placed between January 2014 and December 2018.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was the CVC tip position located on the first postprocedural radiograph. CVC tip was defined as follows: "recommended" (tip location between the carina and two vertebral bodies inferior to the carina), "high" (tip location between one and four vertebral bodies superior to the carina), "low" (tip position three or more vertebral bodies inferior to the carina), and "other" (tip grossly malpositioned). Seven hundred eighty-one CVCs were included: 481 (61.6%) were in "recommended" position, 157 (20.1%) were "high," 131 (16.8%) were "low," and 12 (1.5%) were "other." Multiple multinomial regression (referenced to "recommended" position) showed that left-sided catheters (adjusted odds ratio [aOR], 2.00, 95% CI 1.17-3.40) were associated with "high" CVC tip positions, whereas weight greater than or equal to 40 kg had decreased odds of having a "high" CVC tip compared with the reference (aOR, 0.45; 95% CI, 0.24-0.83). Further, weight category 20-40 kg (aOR, 2.42; 95% CI, 1.38-4.23) and females (aOR, 1.51; 95% CI, 1.01-2.26) were associated with "low" CVC tip positions. There was no difference in rates of central line-associated blood stream infection, venous thromboembolism, or tissue plasminogen activator usage or dose between the CVCs with tips outside and those within the recommended location.

CONCLUSIONS

The prevalence of IJ and SC CVC tips outside of the recommended location was high. Left-sided catheters, patient weight, and sex were associated with malposition. Malpositioned catheters were not associated with increased harm.
