Peripheral Intravenous Attempts Research Articles

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.

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.

Impacting Neonatal Patient Care: Reducing Needle Sticks, with an Extended Dwell Catheter

Highlights Abstract Background: The use and efficacy of extended dwell peripheral intravenous catheters (EPIVs) has been extensively described at scientific conferences and in recent literature. The ramifications of repeated needle sticks include damage to vessels and ultimately the need for more invasive and costly access devices, which clearly support the need for reliable forms of vascular access. Methods: This quality improvement project spanned 4 years, 2017 through 2020, and included 128 patients who required a peripherally inserted catheter as their primary or secondary access site for a prescribed therapy. The EPIV utilized was a 4-cm, 22-gauge catheter made of thermosensitive polyurethane inserted using the Seldinger technique. Results: Over the course of 4 years, 128 patients received an EPIV for 2 or more days, totaling 849 days of therapy. Total insertion attempts were 174 or an average of 1.4 per patient. An estimated number of short PIVs needed for 849 days would have been 404 with 1011 attempts. Resultant savings with EPIV are estimated to be $30,686. Conclusions: Reducing the number of patient peripheral intravenous attempts while extending the dwell time results in less patient trauma, reliable longer-term access, reduced infection risk, reduced supply usage, and savings in terms of nursing time. The ultimate result for preterm newborns is more efficient delivery of care with less cost.

Difficult intravenous access in the emergency department: Performance and impact of ultrasound-guided IV insertion performed by nurses.

Difficult intravenous access (DIVA) is a common problem in Emergency Departments (EDs), yet the prevalence and clinical impact of this condition is poorly understood. Ultrasound-guided peripheral intravenous catheter (USGPIV) insertion is a successful modality for obtaining intravenous (IV) access in patients with DIVA. We aimed to describe the prevalence of DIVA, explore how DIVA affects delivery of care, and determine if nurse insertion of USGPIV improves care delays among patients with DIVA. We retrospectively queried the electronic medical record for all ED patients who had a peripheral IV (PIV) inserted at a tertiary academic medical center from 2015 to 2017. We categorized patients as having DIVA if they required ≥3 PIV attempts or an USGPIV. We compared metrics for care delivery including time-to-IV-access, time-to-laboratory-results, time-to-IV-analgesia, and ED length of stay (LOS) between patients with and without DIVA. We also compared these metrics in patients with DIVA with a physician-inserted USGPIV versus those with a nurse-inserted USGPIV. A total of 147,260 patients were evaluated during the study period. Of these, 13,192 (8.9%) met criteria for DIVA. Patients with DIVA encountered statistically significant delays in time-to-IV-access, time-to-laboratory-results, time-to-IV-analgesia, and ED LOS compared to patients without DIVA (all p<0.001). Patients with nurse-inserted USGPIVs also had statistically significant improvements in time-to-IV-access, time-to-laboratory-results, time-to-IV-analgesia, and ED LOS compared to patients with physician-inserted USGPIVs (all p<0.001). DIVA affects many ED patients and leads to delays in PIV access-related care. Nurse insertion of USGPIVs improves care in patients with DIVA.

Criterion and Construct Validity and Reliability of the Pediatric IV Difficulty Score

Highlights Abstract Background: In pediatric patients, intravenous placement success may be related to predetermined vascular access difficulty. The study purpose was to examine validity and reliability of the 6-item Pediatric Intravenous Difficulty Score. Methods: We determined if a tool that assesses pediatric intravenous difficulty was associated with clinical outcomes of peripheral attempts (criterion validity), hypotheses regarding patients’ age, race, and medical diagnosis (construct validity), and reliability of difficulty levels. Results: In 596 episodes of peripheral intravenous attempts, first-attempt success, overall success, and number of staff attempting access were associated with level of intravenous access difficulty by tool score. The tool met hypothesized construct validity criteria, and in multivariable modeling, the tool was reliable based on difficulty levels of 2 user groups. Conclusions: The 6-item Pediatric Intravenous Difficulty Score has criterion and construct validity and is reliable over time among clinicians with different levels of expertise in peripheral vascular access.

The intraosseous have it: A prospective observational study of vascular access success rates in patients in extremis using video review.

Quick and successful vascular access in injured patients arriving in extremis is crucial to enable early resuscitation and rapid OR transport for definitive repair. We hypothesized that intraosseous (IO) access would be faster and have higher success rates than peripheral intravenous (PIV) or central venous catheters (CVCs). High-definition video recordings of resuscitations for all patients undergoing emergency department thoracotomy from April 2016 to July 2017 were reviewed as part of a quality improvement initiative. Demographics, mechanism of injury, access type, access location, start and stop time, and success of each vascular access attempt were recorded. Times to completion for access types (PIV, IO, CVC) were compared using Kruskal-Wallis test adjusted for multiple comparisons, while categorical outcomes, such as success rates by access type, were compared using χ test or Fisher's exact test. Study patients had a median age of 30 years (interquartile range [IQR], 25-38 years), 92% were male, 92% were African American, and 93% sustained penetrating trauma. A total of 145 access attempts in 38 patients occurred (median, 3.8; SD, 1.4 attempts per patient). There was no difference between duration of PIV and IO attempts (0.63; IQR, 0.35-0.96 vs. 0.39 IQR, 0.13-0.65 minutes, adjusted p = 0.03), but both PIV and IO were faster than CVC attempts (3.2; IQR, 1.72-5.23 minutes; adjusted p < 0.001 for both comparisons). Intraosseous lines had higher success rates than PIVs or CVCs (95% vs. 42% vs. 46%, p < 0.001). Access attempts using IO are as fast as PIV attempts but are more than twice as likely to be successful. Attempts at CVC access in patients in extremis have high rates of failure and take a median of over 3 minutes. While IO access may not completely supplant PIVs and CVCs, IO access should be considered as a first-line therapy for trauma patients in extremis. Therapeutic, level III.

Pediatric Vascular Access Peripheral IV Algorithm Success Rate

PurposeDetermine if the pediatric peripheral vascular access algorithm (PPVAA) led to differences in first-attempt and overall peripheral intravenous (PIV) success, staff attempting PIV access per episode and overall attempts and first PIV attempt success by provider. Design/MethodsA two-cohort pre-/post-implementation comparative design involved pediatric nurses and patients. The PPVAA included four components: a patient comfort plan, PIV grading score, nurses' self-assessed IV access capability and nurse decision to stop-the-line. Two sample t-test or Wilcoxon rank sum test and Pearson's chi-square test were used to evaluate differences between groups and measures. ResultsHealthcare providers (N=96) attempted 721 PIV insertions (pre-PPVAA, n=419 and post-PPVAA, n=302). Of 78 nurse providers, mean (SD) age was 37.4 (11.0) years and 20.0% self-assessed PIV capability as expert. Of children, mean age was 8.3 (7.0) years. Post-PPVAA, first-attempt (p=0.86) and overall (p=0.21) success did not change, though fewer staff were needed per episode to initiate PIV; p=0.017. Overall rate of success after one attempt in the post-PPVAA period compared to pre-PPVAA was reduced (p=0.002), reflecting greater awareness to stop-the-line. Compared to pre-PPVAA, advanced practice nurses and non-clinician providers were more likely to achieve success on first attempt. ConclusionsThe PPVAA did not increase first-attempt or overall PIV success; however, it decreased overall IV attempts and the number of staff attempting access per episode. Practice ImplicationsThe multi-component PPVAA provided a guide for nurses during PIV and assisted decision making to stop attempts in difficult cases.

Prehospital Peripheral Intravenous Vascular Access Success Rates in Children

Objective. Achieving successful peripheral intravenous (PIV) vascular access in children can be difficult. In the prehospital setting, opportunities are rare. Obtaining access becomes vital in emergent and life-threating conditions, such as seizures, hypoglycemia, and cardiac arrest. This study examines prehospital pediatric PIV attempts, success rates, and the impact of patient age. Methods. This was a retrospective chart review of patients aged 18 years or younger receiving prehospital PIV attempts from January 1, 2003, through May 31, 2011. Included cases were identified by querying electronic patient care reports for PIV attempts within the specified age range. The documentation of PIV attempts and successes was reported by emergency medical service providers. This study was approved by an institutional review board. Results. Throughout the 101-month study period, there were 261,008 ambulance responses. PIV attempts were made in 4188 patients aged 18 years or younger. PIV placement was successful in 3699 patients (88.3%) and failed in 489 (11.7%). Age was significantly associated with success. Each 1-year increase in age was associated with an 11% increase in odds of PIV success (odds ratio, 1.11; 95% CI, 1.09–1.12; p < 0.001). Success was lowest in patients younger than 2 years old, with an overall success rate of 64.1% (141/220). Accounting for multiple attempts, success was achieved in 53.0% of attempts (141/266). Conclusions. Prehospital PIV attempts are uncommon (2% of emergent responses). Success rates are significantly associated with patient age in the pediatric population and lowest in those aged 2 years or less. Consideration of alternative forms of vascular access in this population may be beneficial. Key words: ambulance; emergency medical services; intraosseous; intravenous; pediatric

Intravenous Administration Issues

Nurses on a surgical unit compared 2 groups of patients, vancomycin versus other antibiotics, to determine whether vancomycin intravenous therapy is associated with more peripheral intravenous (PIV) complications. Data were collected on a number of PIV attempts and insertions, phlebitis and infiltration scores, nursing time, and missing or late doses on 153 orthopedic and trauma patients. Increased adverse outcomes were found with repeat venipunctures, attempts, nursing time, and infiltration. Patients receiving vancomycin through a PIV catheter developed more complications than those receiving other antibiotics. This is increasingly important because nurses make recommendations for vascular catheters.

Ultrasound-guidance vs. standard technique in difficult vascular access patients by ED technicians

Purpose We evaluated the efficacy and safety of emergency department technicians' (EDT) use of ultrasound (US) guided peripheral intravenous (PIV) access compared to the traditional approach on a subset of patients with difficult IV access. Methods We enrolled a convenience sample of 75 ED patients with difficult IV access (at least 2 failed PIV attempts). During phase I, EDTs used the standard technique. EDTs then attended a didactic session on ultrasound guided PIV access of the upper extremity. In phase II, the EDTs used US guidance for PIV access. Outcome measures were successful PIV cannulation by an EDT, time to cannulation, medical doctor (MD) or registered nurseRN intervention, complications, patient satisfaction, and number of skin punctures. Results Successful cannulation rates were similar (US: 33/41, 80.5%; traditional technique: 24/34, 70.6%) (difference: 9.9%; 95% confidence interval (CI): -9.3%, 29.1%). US was 2.0 times faster (CI 1.3, 3.1), required less MD/RN intervention (7.3% vs. 20.6%) (difference: 13.3%; CI: -2.5, 30.2%), had fewer complications (41.5% vs. 64.7%, difference: 23.3%; CI 0.6%, 42.7%) and skin punctures (1.6 vs. 3.6; difference: 2.0; CI: 1.6, 2.7), and improved patient satisfaction from 4.4 to 7.7 cm ( P-value = .0001). Conclusions Following a brief US training for PIV access, EDTs showed similar success rates but US had significantly improved speed and patient satisfaction with fewer skin punctures and complications.
