The ultrasound-guided versus standard technique for peripheral intravenous catheter placement by nurses: A systematic review and meta-analysis

AimTo comprehensively evaluate the efficacy of Ultrasound-guided technique for peripheral intravenous catheter placement by nurses in their daily practice. BackgroundPeripheral intravenous catheter insertion is a common clinical procedure in healthcare settings. Ultrasound-guided peripheral intravenous placement has emerged in recent decades and was recognized as particularly useful in some specific patient groups. MethodsStudies that had compared the ultrasound-guided and traditional approaches were eligible for inclusion and further analysis. The primary outcome was the success rate on the first intravenous insertion attempt. The secondary outcomes included the time needed for successful insertion, and the average number of attempts to establish the IV access. We systematically assess all studies using Cochrane Collaboration's Risk of Bias tool and the Newcastle-Ottawa Scale. We calculated the odds ratio and standardized mean difference with 95 % confidence intervals for the outcomes. Data were analyzed and visualized on Review Manager 5.3.4 and Stata 16.0. Results23 studies were included (17 randomized controlled trials and six cohort studies) with a population of 2051 patients offered ultrasound-assisted technique and 2479 treated with the conventional approach for comparison. The former approach was associated with a higher success rate on the first attempt in comparison (OR = 2.95, 95 % CI: 1.86, 4.69). This technique also took less time and less acupuncture to patients’ skin (SMD = −0.62, 95 % CI: 1.01, −0.23; SMD = −0.55, 95 % CI: 0.92, −0.18). In the sub-group analyses, children were more likely to benefit from ultrasound guided technique. Ultrasound guided technique demonstrated consistent and significant benefits in emergency clinical settings. Hospitals from different geographical locations exhibited similar trends in the three outcomes. Year of publication and study design revealed inconsistent and insignificant outcomes. ConclusionsUltrasound-guided technique can be a safer, faster, and more effective alternative to the traditional approach for nurses to establish intravenous access across different clinical settings and age groups.

Just-in-time procedural training for pediatric emergency medicine trainees: A randomized educational interventional trial.

Pediatric requirements include procedural skills training such as peripheral intravenous (PIV) catheter placement and bag-mask ventilation (BMV). Clinical experiences may be limited and temporally remote from scheduled teaching. Just-in-time (JIT) training prior to utilization can promote skill development and mitigate learning decay. Our objective was to assess the impact of JIT training on pediatric residents' procedural performance, knowledge, and confidence with PIV placement and BMV. Residents received standardized baseline training in both PIV placement and BMV during scheduled educational programming. Between 3 and 6 months later, participants were randomized and received JIT training for either PIV placement or BMV. JIT training included a brief video and coached practice, totaling <5 min. Each participant was videotaped performing both procedures on skills trainers. Blinded investigators scored performance using skills checklists. Pre- and postintervention knowledge was assessed using multiple-choice and short-answer items, and confidence was reported using Likert scores. Seventy-two residents completed baseline training sessions: 36 were randomized to receive JIT training for PIV and 36 for BMV. Thirty-five residents in each cohort completed the curriculum. There were no significant differences between the cohorts with regard to demographics, baseline knowledge, or prior simulation experience. JIT training was associated with improved procedural performance for PIV (median 87% vs. 70%, p < 0.001) and for BMV (mean 83% vs. 57%, p < 0.001). Results remained significant after using regression models to adjust for differences in prior clinical experience. Improvements in knowledge or confidence were not associated with JIT training in either cohort. JIT training resulted in a significant improvement in resident procedural performance with PIV placement and BMV in a simulated environment. There were no differences in outcome with regard to knowledge or confidence. Future work might explore how the demonstrated benefit translates into the clinical setting.

Asynchronous training for ultrasound-guided peripheral IV placement among critical care nurses.

Teaching ultrasound (US) guidance for placement of peripheral intravenous (PIV) catheters requires significant time for synchronous didactic and hands-on training. The investigators assessed the feasibility of an asynchronous model for critical care nurses to learn the novel skill of US-guided PIV placement. Secondary outcomes included the percentage of successful attempts and number of sticks per attempt for anatomy versus US-guided approaches. The investigators built a self-contained training cart for learners to practice and record their performance. Training occurred asynchronously. The learners recorded data from PIV attempts. Participants completed pre- and post-training surveys. Data from this prospective observational cohort was analyzed for descriptive and comparative statistics, using Kirkpatrick's Model for evaluation of this educational intervention. During a 6 month period, 21 nurses completed the asynchronous training, with eight recording their PIV placements. 81.0% of the training occurred outside of a Monday to Friday 9AM-5PM period. There were 64 attempts by anatomy approach and 84 with US-guidance. The anatomic approach was successful in 35.9% of attempts with a mean of 1.5 sticks (SD 1.0, Range 1-5). The US-guided approach had a statistically significant greater rate of success (77.4%; p < 0.001) with a mean of 1.2 sticks (SD 1.2, range 1-2, p < 0.01). Participants reported increased confidence in US-guided PIV placement and enjoyment with this method of learning. Asynchronous learning model with cart-based instruction and practice is a feasible means for nurses to learn US-guided PIV placement. Significant outcomes were seen across Kirkpatrick levels I-IV for educational outcome assessment.

Factors Affecting Peripheral Intravenous Catheter Placement During Pediatric Trauma Resuscitation

IntroductionIntravenous access is required for resuscitation of injured patients but may be delayed in children because of challenges associated with peripheral intravenous (PIV) catheter placement. Early identification of factors predisposing patients to difficult PIV placement can assist in deciding strategies for timely intravenous access. MethodsWe conducted a retrospective, video-based review of injured children and adolescents treated between April 2018 and May 2019. Patient demographic, physiological, injury, and resuscitation characteristics were obtained from the patient record, including age, race, weight, injury type, Injury Severity Score, initial systolic blood pressure, initial Glasgow Coma Score, intubation status, activation level, and presence of prearrival notification. Video review was used to determine the time to PIV placement, the number of attempts required, the purpose for additional access, and the reason for abandonment of PIV placement. Multivariable regressions were used to determine factors associated with successful placement. ResultsDuring the study period, 154 consented patients underwent attempts at PIV placement in the trauma bay. Placement was successful in 139 (90.3%) patients. Older patients (OR [odds ratio]: 0.9, 95% confidence interval [CI]: 0.9, 0.9) and patients who required the highest level activation response (OR: 0.0, 95% CI: 0.0, 0.3) were less likely to have an attempt at PIV placement abandoned. Children with nonblunt injuries (OR: 11.6, 95% CI: 1.3, 119.2) and pre-existing access (OR: 39.6, 95% CI: 7.0, 350.6) were more likely to have an attempt at PIV placement abandoned. Among patients with successful PIV placement, the time required for establishing PIV access was faster as age increased (−0.5 s, 95% CI: −1.1, −0.0). ConclusionsYounger age was associated with abandonment of PIV attempts and, when successful, increased time to placement. Strategies to improve successful PIV placement and alternate routes of access should be considered early to prevent treatment delays in younger children.

How I Teach: Ultrasound-guided Peripheral Venous Access.

Ultrasound-guided peripheral intravenous (IV) placement is often required for patients with difficult IV access and is associated with a reduction in central line placement. Despite the importance, there is no standardized technical approach, and there is limited ability to attain mastery through simulation. We describe our step-by-step approach for teaching ultrasound-guided IV placement at the bedside using short-axis dynamic guidance, with emphasis on advancing the needle and catheter device almost entirely into the vessel before threading the catheter. Our teaching approach allows the opportunity for trainees to maximize the learning potential of a single insertion experience, which includes focused preprocedure hands-on practice, instruction with real-time feedback at the bedside, and a post-procedure debrief with reinforcement of concepts.

Development and Implementation of an Ultrasound-Guided Peripheral Intravenous Catheter Education Program for Critical Care Nurses.

Ultrasound-guided (US-guided) peripheral intravenous (PIV) insertion is a skill used by specially trained nurses for patients with difficult vascular access. It can result in potential complications such as occlusive thrombus, phlebitis, infiltration, and pain. Complications can be prevented or minimized with clinical training to achieve competency. Current research shows that the most effective approach to US-guided PIV training consists of a comprehensive structured educational program that includes didactic, hands-on training and skills application. This study aimed to develop and implement a US-guided PIV education program for critical care nurses. Structured education was developed using a step-wise method. Critical care nurse practitioners in the intensive care unit (ICU) developed training materials including hands-on training, ultrasound reference material, and supervised skills application. Afterward, US-guided PIV-trained critical care nurses were enabled to train other nurses in the ICU. The total number of US-guided PIV-trained registered nurses in the ICU increased from 5.8% to 26% of staff, but represents only 20% of those trained at current staffing levels. The percentage of US-guided PIV-trained nightshift/weekend staff increased from 3.9% to 24%, but represents 14% at current staffing levels. One hundred five US-guided PIVs showed a 97% success rate of US-guided PIV placement during an 11-month timeframe, similar to success rates published in the literature that ranged from 86% to 100%. There was 1.9% complication rate for occlusive thrombus, which is below published rates ranging up to 10%. Critical care nurse practitioners in the ICU collaborated with vascular nursing and hospital clinical education to successfully develop and implement a US-guided PIV training program to meet patient needs within a growing community facility. The results of the training program yielded similar success and complication rates as those reported in the literature. Ongoing training is essential for program sustainability. Critical care nurse practitioners training registered nurses in US-guided PIV placement is an effective approach to training. Critical care nurses trained in US-guided PIV insertion can safely and effectively train other critical care nurses in US-guided PIV insertion.

Characterization of the Difficult Peripheral IV in the Perioperative Setting: A Prospective, Observational Study of Intravenous Access for Pediatric Patients Undergoing Anesthesia.

BackgroundVarious criteria exist for defining difficult intravenous access (DIVA) in infants and children. The current study evaluated the factors associated with DIVA in a prospective cohort of over 1000 infants and children presenting for anesthetic care.MethodsThis was a prospective, observational study of patients aged 0 to 18 years undergoing elective surgical or radiologic procedures under general anesthesia. Prior to the initial attempt at peripheral intravenous (PIV) cannulation, the anticipated difficulty of PIV catheter placement was determined by the provider using a visual analogue scale (VAS) from 1 to 10. The number of attempts was recorded as well as the time required to achieve PIV access. DIVA was defined as requiring three or more attempts. After successful cannulation, the actual difficulty of the PIV placement was assessed by the provider and recorded using the same VAS. Patient characteristics, including age, race, body mass index (BMI), American Society of Anesthesiologists (ASA) physical classification, and history of difficult PIV placement, were evaluated as covariates.ResultsIn our cohort of 1002 pediatric patients, 78% of patients were successfully cannulated in a single attempt and 91% of patients were successfully cannulated in two or fewer attempts. Factors associated with requiring three or more PIV attempts included younger age (OR 8.73; 95% CI: 3.38, 22.6 for age <1 year and OR 4.93; 95% CI: 2.05, 11.8 for age 1–3 years), higher ASA physical classification (OR 1.95; 95% CI: 1.10, 3.46 for ASA II), and prior history of difficult PIV placement (OR 3.46; 95% CI: 1.70, 7.08). BMI, racial category or gender were not independent predictors of DIVA.ConclusionWe found that approximately 9% of patients required three or more attempts at IV placement in the operating room. Patients that required multiple PIV attempts were more likely to be younger, have a higher ASA classification or a history of difficult PIV placement.

Development and assessment of an efficient pediatric affect and cooperation scale

Study objectiveHRAD± was developed to quickly evaluate pediatric preprocedural affect and cooperativity during mask induction of anesthesia and peripheral intravenous (PIV) placement. HRAD± represents: Happy, Relaxed, Anxious, Distressed, with a yes/no answer to cooperativity. The primary aim of this study was to compare HRAD± to previously published scales. DesignWe conducted an observational study. SettingVideos of pediatric patients were collected in the perioperative environment. PatientsTwenty-four children, twenty-one pediatric anesthesiologists and twenty pediatric perioperative providers were included. InterventionsTo assess the reliability of HRAD±, standard patient videos were created. Children underwent mask induction or PIV placement, and these interventions were video recorded. Mask induction and PIV placement videos were rated by pediatric anesthesiologists and perioperative non-physician providers respectively using HRAD±. MeasurementsTwo trained researchers provided the modified Yale Preoperative Anxiety Scale (mYPAS), Observation Scale of Behavioral Distress (OSBD), and Induction Compliance Checklist (ICC) scores, and we calculated correlations to HRAD±, inter-rater reliability, and intra-rater reliability. Main resultsHRAD± scores strongly correlated with mYPAS (r = 0.846, p < 0.0001) and OSBD scores (r = 0.723, p < 0.0001). Cooperativity scores correlated strongly with ICC scores in the mask induction group (r = −0.715, p < 0.0001) and in the PIV group (r = −0.869, p < 0.0001).HRAD± inter-rater reliability for mask induction was 0.414 (p < 0.0001) and for PIV assessment was 0.378 (p < 0.0001). Inter-rater reliability for cooperativity on mask induction was 0.797 (p < 0.0001) and PIV assessment was 0.683 (p < 0.0001). Intra-rater reliability for mask induction was 0.675 and PIV assessments was 0.678. Intra-rater reliability for cooperativity for mask induction was 0.894 and for PIV assessments was 0.765. ConclusionsHRAD± is an efficient and reliable scale that serves as a practical alternative for measuring pediatric affect during mask induction and PIV placement. The results demonstrate strong correlation with commonly utilized yet more complex affect scales.

Comparative Study on Intravenous Catheter Insertion Pain control, Anxiety, and Satisfaction in Adult Same Day Surgery Patient; Using a Vibrating, Cold Device or Traditional Local Anesthetics Intradermal Injection

<h3>Introduction</h3> Intradermal local anesthetic injection has been shown to be effective in decreasing pain during peripheral intravenous placement compared with other interventions. Current research has identified that distraction techniques and topical anesthetics are effective in decreasing pain and anxiety during painful procedures. Vibration, cold and other tactile stimulation are also mechanisms for reducing the pain sensation <h3>Identification of the problem</h3> Pain from intravenous placement is one of the most frequent, painful, anxiety provoking events experienced by patients in the hospital. Current popular method to decrease pain during venipuncture is intradermal local anesthetic injection which is not within nursing scope of practice. Alternatives that may be used, such as the vibrating cold device should be explored. <h3>Purpose of the Study</h3> To determine if there is a difference between intravenous insertion techniques used to manage pain, anxiety and patient experience in adult pre-operative patients. Techniques compared are intradermal local anesthetic injection and an external vibrating/cold device. <h3>Methodology</h3> Experimental, Randomized Controlled Trial. Subjects approached through face to face invitation to participate and consent to be in the study. A coin was flipped to determine if they will receive vibrating/cold device or intradermal lidocaine injection as means of venipuncture comfort measure. Members of the research team utilized a de-identified data collection tool and subjects were asked to complete surveys after the intervention; pain score, anxiety rating, and satisfaction rating based on a Likert scale. <h3>Results</h3> 1.00=Vibrating Cold Device 2.00=Local Anesthetic Intradermal <h3>Discussion</h3> Vibrating cold device (VCD) mean pain score of 3.1 is considered mild pain intensity. Use of VCD yielded lower levels of anxiety and comparable satisfaction scores when comparted to Local anesthetic intradermal. <h3>Conclusion</h3> Vibrating cold device may be used, within the scope of nursing practice, to provide pain control during IV insertion. This intervention also has a positive effect on the anxiety level experienced by patients during IV insertion and offers a high level of patient satisfaction. <h3>Implications for perianesthesia nurses and future research</h3> Use of Vibration, cold and other tactile stimulation as mechanisms for reducing pain sensation experienced by patients post procedure.

Assessing Ease of Delivering Emergency Care for Patients with Autism Spectrum Disorders.

The aim of this study was to develop a method for objectively assessing the delivery of care to children with autism spectrum disorder (ASD) in the emergency department (ED). A case-control study of patients ages 2 to 18 years admitted to the hospital from January 2016 to January 2018. Cases were defined as patients with an International Classification of Diseases, Tenth Revision diagnosis of ASD or other pervasive developmental disorder (F84) in their medical record and were matched 1:1 with neurotypical controls. The primary outcome was ability to complete several core tasks clinically necessary within an ED visit and summarized into a Task Completion Index (TCI). Overall, children with ASD had higher median TCIs of 0.25 (interquartile range [IQR] 0-0.45) versus 0 (IQR 0-0.25) when compared with children without ASD (p < 0.01). Children with ASD were 5 times more likely to have difficulty with triage vitals, 3 times more likely to require additional staff for peripheral intravenous placement, and 4 times more likely to experience delays or disruptions to their plan of care. The TCI was also associated with 8-fold increased odds of receiving pharmacologic or physical restraint. The TCI reflects difficulty accomplishing core tasks necessary to complete an ED visit. Children with ASD have higher TCIs than neurotypical controls, which puts them at higher risk for care disruptions. Evaluation of initiatives to improve quality of care for children with ASD should focus not only on metrics of overall experience and satisfaction but also how these initiatives affect the ability to effectively administer care.

Training the Trainers in Ultrasound-guided Access to Improve Peripheral Intravenous Catheter Placement among Children Presenting for Anesthesia.

We implemented an evidence-based difficult IV algorithm and ultrasound-guided PIV placement training for attending pediatric anesthesiologists at a tertiary academic pediatric institution. The algorithm outlined risk factors for difficult IV access, established a goal of 3 or fewer attempts, and recommended early ultrasound use after 1 unanticipated attempt and the first attempt for anticipated difficult IV. Group sessions, including instruction and simulated practice, preceded a period of individual training in the operating room using a punch card to monitor each trainee's progress while also serving to motivate continued engagement. We performed a cross-sectional analysis of consecutive cases from December 1, 2015, to September 30, 2019, comparing a 22-month baseline period (n = 12,581) with the training period (n = 6,725) and the following year (n = 6,557). Cases requiring more than 3 attempts decreased from 4.0% to 2.7% overall and from 10% to 6.2% among patients 24 months or less of age. The time required to establish PIV access was unchanged. Factors associated with increased attempts were identified. Implementing a difficult IV algorithm and training among attending pediatric anesthesiologists in ultrasound-guided PIV placement reduced attempts but not the time required to establish PIV access.

Using Ultrasound-guided PIV Insertion in the Pediatric Population to Decrease Insertion Attempts

Intravenous (IV) therapy using a peripheral IV (PIV) in children is a medical intervention frequently used in hospitals. Current evidence supports ultrasound-guided PIV placement in the adult patient population. The purpose of this study was to implement an evidence-based practice approach to determine if ultrasound-guided IV insertion decreased the number of attempts for successful cannulation and improved staff and patient satisfaction with the treatment in the pediatric inpatient population. Data collection was conducted in a pediatric medical surgical unit and pediatric intensive care unit (PICU). After the implementation of ultrasound-guided IV insertion, the average number of attempts necessary for successful insertion decreased from 2 to 1.37. Findings support the integration of ultrasound-guided IV insertion into the standard of care on pediatric medical surgical units and PICUs.

Infrared vein visualization devices for ease of intravenous access in children: hope versus hype.

Peripheral intravenous placement can be difficult in children. Vein finder devices are vascular access devices that delineate veins lying in the subcutaneous tissues to identify potential venipuncture sites. In this narrative review, we highlight the currently available literature on this device to analyse the hope that this device has to offer vs. the unnecessary hype. The search of the databases (Cochrane Library, Google Scholar, and PubMed) was limited to studies on the paediatric population and in English language between 2011 and 2019. Twenty-three relevant articles were found. Most of the articles did not demonstrate amajor impact of these modalities in the general paediatric population. However, they may be beneficial in children with difficult intravenous access. Appro-priate simulator mannequins should be utilised to train healthcare providers in using these vein finder devices.

Topical Refrigerant Spray for IVs: Patient/Provider Responses - Prospective, Double-blind, Randomized Study.

Painful procedures are common. Patients prefer analgesia for painful procedures. Studies indicate that use of a topical refrigerant spray (TRS) prior to needlestick procedures decreases needlestick pain. TRS is easy to apply, inexpensive, has fast onset, and avoids needlestick pain and anxiety, and needlestick injury risk. Patient and health care provider (HCP) acceptance of any technique is essential before it is adopted. This study evaluated the decrease in pain with TRS and the patient and HCP satisfaction and acceptance of TRS for peripheral intravenous (PIV) placement. Adults (N = 300) randomized to placebo or TRS and HCPs (N = 300) placing PIVs answered questionnaires. Patients had significantly less pain than with prior PIVs, and were satisfied with and would use TRS in the future (P < 0.001). HCP felt that patients had significantly (P < 0.001) less pain with TRS than the placebo, and were satisfied with the TRS, and would use TRS in the future.Registered at Clinicaltrials.gov NCT01670487.

Things We DON'T Do for No Reason.

In 2010, Dr Howard Brody introduced the idea of “the top 5 list” in the New England Journal of Medicine , calling on medical specialties to identify items of overuse to provide high-value care.1 This led to the “choosing wisely” campaign to identify commonly overused measures in medicine in >70 different medical specialties.1 One aspect of this campaign is the “Things We Do For No Reason” articles in the Journal of Hospital Medicine , which focus on the evidence behind common overuse, overdiagnosis, or high-value care issues. These discussions are an important part of pediatric hospital medicine, and efforts to promote this subject must continue. As hospitalists, we also have an obligation to reassess things we should be doing. We will discuss 3 examples briefly in this article but encourage this discussion to continue, at conferences, meetings, and break rooms everywhere. Bronchiolitis is the most common reason infants are hospitalized, and over half require nonoral hydration.2,3 Multiple studies have shown that enteral and nasogastric hydration is comparable to intravenous (IV) hydration in terms of safety and tolerance.2,4,5 A large, randomized controlled trial of infants hospitalized with bronchiolitis did not reveal any significant difference in rates of ICU admission, oxygen therapy duration, ventilator support requirement, or length of stay when comparing IV with nasogastric hydration.2 In a 2018 survey, only 12% of physicians and nurses would choose nasogastric hydration for a healthy infant with bronchiolitis.6 Many practitioners reported concerns about nasal obstruction, parental resistance, and aspiration risk, and 66% did not know that nasogastric hydration was a documented …

The Effect of Catheter Length Placed Into the Vein on Peripheral Ultrasound-Guided Catheter Survival Time: A Prospective Observational Study

IntroductionEstablishing and maintaining peripheral intravenous access in patients with no visible or palpable veins can be arduous. Intravenous catheters placed with ultrasound do not survive as long as traditionally placed catheters. This study was performed to determine the relationship between the catheter length placed into the lumen of the vein using ultrasound and catheter survival. MethodsThis was a nonrandomized prospective observational study of admitted patients with difficult intravenous placement in 2017. Subjects had ultrasound-guided peripheral intravenous placement in the emergency department or intensive care unit. The main outcome was the time of catheter survival. Data were analyzed using descriptive statistics and Cox regression. ResultsA total of 98 patients with an average age of 63 years were enrolled. The total number of cases examined was 97 (N = 97), of which 29 intravenous catheters were removed for catheter-related problems (events). The mean (SD) survival time for catheters placed using ultrasound was 3,445 minutes (2,414) or 2.39 days. Peripheral catheter survival was not significantly related to the in-vein length of the catheter (X2 = 0.03, P = 0.86) nor was it significantly related to any of the covariates. DiscussionThe survival time of ultrasound-guided intravenous access doubled in the present study from 1674 minutes in a previous 2013 study. The results may have been due to clinician expertise and experience with the peripheral ultrasound-guided method and the use of updated equipment.

Handheld Ultrasound: Overcoming the Challenge of Difficult Peripheral Intravenous Access in the Emergency Department.

The purpose of this study was to evaluate the performance of a handheld ultrasound device for difficult peripheral intravenous (PIV) access performed by nurses and paramedics in the emergency department (ED). This was a retrospective review at an academic medical center. Participants were ED nurses and paramedics with competence in ultrasound-guided PIV placement. Participants were asked to log their use of the handheld device when used on patients deemed to have "difficult" access and complete a questionnaire, which consisted of items related to the effectiveness and ease of use of the device. Data were collected over the course of 1 year. An electronic medical record review was performed to track the success rates and the occurrence of any associated complications throughout the hospital stay. Nurses and paramedics logged a total of 483 cases in which PIV access was attempted with the handheld ultrasound device. Ninety-two percent (95% confidence interval [CI], 89%-94%) of the ultrasound-guided PIV lines attempted were placed successfully. Eighty-four percent (95% CI, 80%-87%) of the lines were placed successfully on the first attempt. In most cases (396 of 483 [82%]), no complications associated with the PIV occurred. A total of 429 questionnaires were completed over the study period. Most of the operators (84%; 95% CI, 80%-87%) stated that the handheld device was adequate to perform ultrasound-guided PIV access. The handheld ultrasound device performed well in terms of usability and reliability for PIV access.

Ultrasound-detected venous changes associated with peripheral intravenous placement in children.

Ultrasound shows several venous changes in pediatric PIV-containing veins. Changes were visualized by ultrasound in the absence of physical exam findings. Venous luminal narrowing, wall thickening, and thrombosis may explain PIV failure. Peripheral intravenous catheters (PIVs) are routinely used for venous access in hospitalized pediatric patients to administer fluids and medications and to aspirate blood. Unfortunately, PIVs do not remain functional for the entire duration of intravascular need. We hypothesized that PIV malfunction may be related to venous changes that can be visualized with ultrasound (US) imaging. The purpose of this study was to describe and document such changes in pediatric patients. This Institutional Review Board-approved study was performed at a tertiary pediatric medical center. Patients underwent US scans of their PIV-containing veins, documenting venous characteristics such as depth, diameter, wall thickness, blood flow, valves, branch points, and presence of thrombus. Patient demographics and PIV characteristics were also recorded. Data from 30 patients including 12 males and 18 females with a mean age of 11 years were analyzed. Mean venous depth and diameter were 2.07 ± 0.13 and 2.02 ± 0.18 mm, respectively. Mean PIV dwell time at time of evaluation was 3.3 days. PIV-associated venous changes were seen in 73% of accessed veins and included lumen narrowing (47%), wall thickening (33%), presence of thrombus (20%), and absence of blood flow around the PIV tip (40%). PIV-associated venous changes are seen with US in the majority of pediatric patients with indwelling PIVs but are not necessarily appreciated on physical exam. These changes may help explain the high rate of pediatric PIV device failure. Given the small sample size, further investigation is needed to better characterize PIV-associated venous changes in children.

Effectiveness of vialon biomaterial versus teflon catheters for peripheral intravenous placement: A randomized clinical trial.

This study was to determine the effects of the two types of catheter material (vialon biomaterial and teflon) on pain intensity, dwell time, and phlebitis score for peripheral intravenous catheter (PIVC) placement. Participants (N = 208) were randomly assigned to the vialon biomaterial group (n = 104), the teflon group (n = 104). After the PIVC placement, the intensity of pain and phlebitis score were evaluated. Catheter dwell mean time was determined. The pain intensity scores were similar immediately after inserting the PIVC. No difference was observed between the pain scores in both groups (p ≥ .050). Catheter dwell mean time for the vialon biomaterial catheter group (4.72 ± 1.20 days) was significantly longer compared to the teflon catheter group (4.10 ± 0.92 days) (p ≤ .001). It was determined that the catheter was removed due to phlebitis development in 16.3% of the vialon biomaterial catheter group and 53.8% of the teflon catheter group. An advanced level of statistically significant difference was found between the two groups in terms of phlebitis development scores (p ≤ .001). This study concluded that vialon biomaterial catheter (BD Insyte™ Autoguard™ BC winged) demonstrates longer dwell time of PIVC, lower phlebitis rate and phlebitis score than teflon catheter (BD Venflon™).
