Uncommon Malposition of an Ultrasound-Guided Central Venous Catheter in the Renal Vein through the Superficial Femoral Vein: A Case Report.

Introduction: Malposition is a relatively rare complication associated with peripherally inserted central catheters (PICCs), particularly in cases of superficial femoral vein (SFV) catheterization. To the best of our knowledge, we are the first to report this rare case of SFV PICC malposition in the contralateral renal vein. Case presentation: An 82-year-old woman underwent bedside cannulation of the SFV for PICC under ultrasound guidance. Subsequent radiographic examination revealed an unexpected misplacement, with the catheter tip positioned toward the contralateral renal vein. After pulling out the catheter on the basis of the X-ray result, it was observed that the catheter retained its function. Conclusion: Although rare, tip misplacement should be considered in SFV PICC placement. Prompt correction of the tip position is crucial to prevent catheter malfunction and further catastrophic consequences. For critical patients receiving bedside SFV PICC insertion, postoperational X-ray is crucial for enhancing safety.

Deep Learning for Predicting Phlebitis in Patients with Intravenous Catheters.

This study presents a deep learning model to predict phlebitis in patients with peripheral intravenous catheter (PIVC) insertions. Leveraging electronic health record data from 27,532 admissions and 70,293 PIVC events at a hospital in Seoul, South Korea, the study involved analyzing patient demographics, PIVC-specific features, and drug-related information. The developed deep learning model was benchmarked against various machine learning models, demonstrating superior performance with an accuracy of 0.93 and an AUC of 0.89. This highlights its potential as an effective tool for early detection of phlebitis, promising enhanced patient outcomes and healthcare efficiency.

Nurses' evidence-based knowledge and self-efficacy in venous access device insertion and management: Development and validation of a questionnaire.

AIM: To develop and psychometrically test an instrument to assess nurses' evidence-based knowledge and self-efficacy regarding insertion and management of venous access devices (short peripheral catheter (SPC), long peripheral catheter/midline (LPC) and PICC) and the management of totally implantable central venous catheter (Port) in adult patients. DESIGN: Multicenter cross-sectional observational study with questionnaire development and psychometric testing (validity and reliability). METHODS: An evidence-based instrument was developed including a 34-item knowledge section and an 81-item self-efficacy section including four device-specific parts. Nineteen experts evaluated content validity. A pilot study was conducted with 86 nurses. Difficulty and discrimination indices were calculated for knowledge items. Confirmatory factor analyses tested the dimensionality of the self-efficacy section according to the development model. Construct validity was tested through known group validity. Reliability was evaluated through Cronbach's alpha coefficient for unidimensional scales and omega coefficients for multidimensional scales. RESULTS: Content validity indices and results from the pilot study were excellent with all the item-content validity indices >0.78 and scale-content validity index ranging from 0.96 to 0.99. The survey was completed by 425 nurses. Difficulty and discrimination indices for knowledge items were acceptable with most items (58.8%) showing desirable difficulty and most items (58.8%) with excellent (35.3%) or good (23.5%) discrimination power, and appropriate to the content. The dimensionality of the model posited for self-efficacy was confirmed with adequate fit indices (e.g., comparative fit index range 0.984-0.996, root mean square error of approximation range 0.054-0.073). Construct validity was determined and reliability was excellent with alpha values ranging from 0.843 to 0.946 and omega coefficients ranging from 0.833 to 0.933. Therefore, a valid and reliable tool based on updated guidelines is made available to evaluate nurses' competencies for venous access insertion and management.

Factors influencing peripheral intravenous catheter practice of nurses in small and medium sized hospitals: a cross-sectional study.

BACKGROUND: The importance of the peripheral intravenous catheter (PIVC) practices on patient safety is increasing. Small and medium-sized hospitals play a central role in the provision of healthcare services in South Korea, but lack a system for quality improvement, leaving patient safety at risk. This study aimed to identify the extent to which the PIVC practice knowledge of nurses, the nursing working environment, and the patient safety-culture perception affect PIVC practices and thereby provide basic data for improving the PIVC practices in small and medium-sized hospitals. METHODS: This study had a cross-sectional descriptive design to identify the factors affecting PIVC nursing practices in small and medium-sized hospitals. Questionnaires returned by 149 nurses collected data on general characteristics, practical knowledge of PIVC nursing, nursing working environment, patient safety-culture perception, and PIVC practices. The questionnaire data were analysed using descriptive statistics, the independent t-test, one-way ANOVA, Scheffé's test, Pearson correlation, and hierarchical regression analysis. RESULTS: The mean score of PIVC practices was 4.60 out of 5. Length of clinical experience, practical knowledge of PIVC nursing and patient safety-culture perception were significant factors affecting the PIVC nursing practices, with these variables explaining 26.2% of the variance therein. CONCLUSIONS: The PIVC practices of nurses in small and medium-sized hospitals can be improved by providing education and training based on the latest standard or guideline to facilitate the acquisition of knowledge and skills. And campaigns and programs to strengthen patient safety culture perception specific to small and medium-sized hospital should be implemented. to ensure the safety of PIVC practice.

Factors associated with the disinfection of devices attached to peripheral intravenous catheters performed by the nursing team in pediatric units.

Background: Peripheral intravenous catheterization, as well as drug administration through it, represents one of the most performed procedures by the Nursing team and, for that, precautions need to be adopted to offer harm-free care. Objective: To verify the association of Nursing professionals' work shift and training time with proper disinfection of intravenous catheter devices in pediatric units. Methods: A cross-sectional and analytical study conducted between June and August 2021 in three hospitalization units of a Pediatric Hospital. The inclusion criterion was drug administration via peripheral intravenous catheters performed by Nursing professionals. The data were analyzed according to inferential statistics, adopting p ≤ .05 as significance level. Results: There were a total of 385 observations of drug administration procedures. The device was not disinfected in 60.3% of the cases, there was no friction at the suitable time in 86.3%, and the disinfectant was not allowed to dry in 72.5%. The work shift exerted no influence on performance of the disinfection procedure (p = .376). However, longer training time was associated with a lower rate in performing such procedure (p < .001). Conclusion: Performing friction below the recommended time can cause a false sense of prevention of catheter-associated bloodstream infection; therefore, training sessions and strategies for adherence to the disinfection procedures should be considered, mainly for professionals with more training time.

The safe implementation of peripherally inserted central catheters by nurse practitioners for patients with gastroenterological diseases in Japan: a single-center retrospective study.

PURPOSE: As a safe and reliable alternative to central venous catheters (CVCs), peripherally inserted central catheters (PICCs) are commonly used in clinical practice. However, the insertion of PICCs by nurse practitioners (NPs), especially in Japan, has not been reported extensively. Thus, we investigated the safety and efficiency of PICC insertions by NPs. METHODS: The participants were 1322 patients who underwent PICC insertion by NPs at Fujita Health University Hospital (FNPs). The basilic vein in the brachium was the preferred vein for insertion; the brachial vein was the alternative. Patients were monitored from the time of PICC insertion until its removal. Ultrasonography-guided puncture was used for all catheter insertions, and the catheter tip was replaced into the superior vena cava under fluoroscopic imaging with maximal sterile barrier precautions. The outcomes of the PICC insertions by the FNPs were evaluated retrospectively. RESULTS: Overall, 23 FNPs inserted a collective total of 1322 PICCs, which remained in place for a collective total of 23,619 catheter days. The rate of successful PICC insertion was 99% (1310 patients). The median time taken for PICC insertion was 12 min (interquartile range, 10-15 min). Intraoperative complications occurred in two patients (0.2%). The confirmed incidence of central line-associated bloodstream infection was 3.4% (45 patients), and these infections occurred on 1.9 per 1000 catheter days. The median duration of PICC placement was 15 days (range, 10-23 days). CONCLUSION: PICC insertion by NPs is safe and a potential alternative to CVC insertion by surgeons.

Objective: to analyze the effectiveness of peripherally inserted central catheter insertion techniques in preventing the occurrence of complications related to this device in newborns. Method: a paired and network systematic literature review and meta-analysis, with its search carried out in seven databases and in the Grey Literature, including randomized and non-randomized clinical trials. The risk of bias was assessed using the Cochrane Risk of Bias 2 and Risk of Bias In Non-randomized Studies of Interventions tools. Certainty of the evidence was assessed by means of the Grading of Recommendations Assessment, Development and Evaluation. A meta-analysis was carried out with the aid of the R statistical program. Results: eight studies with 1,126 newborns were included and six insertion techniques were identified: intracavitary electrocardiogram; intracavitary electrocardiogram associated with ultrasound; ultrasound; formula; anatomical landmark; and modified anatomical landmark. Five techniques significantly decreased primary tip malpositioning when compared to the control ( p <0.05). Intracavitary electrocardiogram significantly and more effectively reduced arrhythmias, general complications and phlebitis; the technique that used a formula also reduced general complications. Infection, infiltration, secondary tip malpositioning, catheter rupture, thrombosis, occlusion and catheter-associated skin lesion were not significantly preventable events. Conclusion: intracavitary electrocardiogram and use of the formula were the most effective techniques in reducing complications.

Selective Venous Sampling Prompting Unilateral Oophorectomy in an Adolescent With PCOS and Markedly Elevated Testosterone.

BACKGROUND: For adolescents with suspected polycystic ovary syndrome (PCOS) and severely elevated testosterone concentrations, imaging is recommended to assess for neoplasm. Selective venous sampling (SVS) can be considered when imaging is nondiagnostic. CASE: An adolescent female treated for PCOS had a peak testosterone of 344 ng/dL (11.9 nmol/L). Imaging did not localize a mass. SVS implicated the right ovary as the source of hyperandrogenism. Following laparoscopic right oophorectomy, pathology excluded a neoplasm and confirmed PCOS. She subsequently had rapid and persistent improvement in her hyperandrogenism. SUMMARY AND CONCLUSION: Striking testosterone elevation can occur with adolescent PCOS. SVS is a tool for localizing the source of severe hyperandrogenism, yet unilaterality is not always diagnostic of a neoplasm. Unilateral oophorectomy could nonetheless be therapeutic for severe PCOS.

Investigating the Kazakhstani Pediatric Nurses' intravenous catheter management knowledge and confidence: A cross-sectional study.

AIM: To assess Kazakh pediatric nurses' knowledge and confidence in peripheral intravenous catheter (PIVC) management and examine the personal and professional factors that influenced them. BACKGROUND: Despite the significance of having high levels of PIVC insertion and care knowledge and confidence among pediatric nurses, the literature portrays inadequacies in the knowledge of these nurses in various parts of the globe. DESIGN: This study is cross-sectional and observational, following the STrengthening the Reporting of OBservational studies in Epidemiology checklist in reporting. METHODS: A convenience sample of 200 pediatric nurses working in the University Medical Center in Kazakhstan were surveyed from November to December 2022 using a paper-based questionnaire to assess the PIVC management knowledge and confidence. RESULTS: The respondents had poor knowledge of patient assessment, PIVC insertion, maintenance, and removal. Participants reported high confidence in inserting and maintaining PIVCs among pediatric patients. Nurses' education, pediatric nursing experience, and training in PIVC management in the last 12 months were significant predictors of the nurses' knowledge. PIVC insertion and care knowledge directly influenced the nurses' confidence in these procedures. CONCLUSIONS: Despite the high confidence of the nurses, their actual knowledge of these skills needed to be higher. Some personal and professional factors influence the knowledge and confidence of pediatric nurses.

Effect of rapid cycle deliberate practice in peripheral intravenous catheters insertion training: A simulation experimental study.

AIM: to compare the effect of rapid cycle deliberate practice simulation training with skill-training simulation on peripheral intravenous catheter insertion for Licensed Practical Nurses. BACKGROUND: The use of peripheral intravenous catheters is associated with high rates of complications, although it is widely used in clinical practice. Training strategies to ensure good performance can minimize the risks inherent to this procedure. DESIGN: A randomized simulation experimental pre-post interventional study. METHODS: Sixty participants were allocated to intervention (n = 30) or control (n = 30) groups. Participants allocated to the intervention group were trained through the Rapid cycle deliberate practice simulation strategy, while participants in the control group were trained through the skill-training simulation strategy. A pre-test was applied before any intervention and a post-test after intervention. The primary outcome was the performance in the peripheral intravenous catheter insertion skill. The comparison of correct performance in the tests was analyzed intergroup and intragroup. The effect size of the interventions was also analyzed. The t-Student and Mann-Whitney tests compared the difference between the groups. The training effect was calculated by Cohen's dm and Glass's Δ measures. RESULTS: Performance between the pre-post-test increased from 59.4% to 96% (p < 0.001) in the intervention group and from 57.8% to 93.5% in the control group (p < 0001). There was no statistical difference between the groups after intervention (p = 0225). Cohen's dm measurement was 2.95 and 3.59 in the control and intervention groups, respectively. CONCLUSIONS: The rapid cycle deliberate practice simulation strategy resulted in Licensed Practical Nurses' performance improvements in peripheral intravenous catheter insertion, evidenced by the increase of correct performance actions in the post-test compared to the pre-test. However, with no statistical difference compared to the skill-training simulation strategy.

Comparison of procedure-related pain and patient satisfaction according to catheter size and insertion site in peripheral intravenous catheterization.

BACKGROUND: Peripheral intravenous catheterization is a painful and uncomfortable procedure and is the most commonly used invasive procedure in healthcare institutions. Compare procedure-related pain and patient satisfaction according to catheter size and insertion site in peripheral intravenous catheterization. METHODS: The study was comparative prospective randomized study. Individual Information Form, Visual Analog Scale, and Patient Satisfaction Scale about Catheterization were used for data collection. RESULTS: The highest pain score and the lowest patient satisfaction were determined in 20 gage insertion in the dorsum of the hand. It was less painful to perform the procedure in the forearm than in the dorsum of the hand. Moreover, there was a significant negative correlation between the level of pain experienced due to peripheral intravenous catheterization and patient satisfaction with catheterization. CONCLUSIONS: A smaller peripheral intravenous catheter inserted in the forearm resulted in less pain sensation and higher patient satisfaction.

Comparison between Wright and Shukla formulas: which is better for the placement of umbilical catheters in newborns ≤ 1500 g?

BACKGROUND: Intravascular venous (VUC) or arterial (AUC) umbilical catheter placement is the most frequent invasive procedure in the neonatal intensive care unit (NICU). Either Wright's or Shukla's formula is used to introduce the catheters. However, Shukla's formula is associated with incorrect insertion, especially for newborns < 1500 g. This study aimed to determine by chest X-ray if Wright's formula is better than Shukla's formula for the correct placement of umbilical catheters in newborns ≤ 1500 g. METHODS: We included patients admitted to the NICU of a secondary-level hospital between 2021-2022 who received VUC or AUC through the Wright or Shukla formulas. RESULTS: A total of 129 newborns were included: 78 with VUC and 51 with AUC. In VUC, 50% with Wright and 36.8% with Shukla formulas had the correct location, (p = 0.24). In AUC, 56.6 % with Wright and 52.4% with Shukla formulas were placed correctly placed, (p = 0.76). VUC with weight < 1000 g were correctly placed in 36.4% with Wright and 33.3% with Shukla formulas (p = 0.58). VUC in newborns > 1000 g were correctly placed in 66.6% with Wright and 38.4% with Shukla formulas (p = 0.065). AUC in newborns < 1000 g were correctly placed in 45% using Wright and 42.9% Shukla formulas (p = 0.63). AUC in newborns > 1000 g were correctly placed in 80% using Wright and 57.1% Shukla formulas (p = 0.23). CONCLUSIONS: We found 13% more correctly placed VUC using Wright's formula. Moreover, Wright's formula was 29% above Shukla's VUC placement in neonates > 1000 g, although there was no significant difference due to the sample size.

Métodos: Se incluyeron los pacientes ingresados en la UCIN de un hospital de segundo nivel entre 2021-2022 que recibieron CVU o CAU mediante las fórmulas de Wrigth o Shukla. Resultados: Se incluyeron en total 129 recién nacidos: 78 CVU y 51 CAU. En CVU, Wright 50% y Shukla 36.8% tuvieron localización correcta, p = 0.24. En las CAU, Wright 56.6% y Shukla 52.4% tenían una ubicación correcta, p = 0.76. En CVU con peso < 1000 g, Wright 36.4% y Shukla 33.3% bien situados, p = 0.58. En CVU > 1000 g, Wright 66.6% y Shukla 38.4% bien situados, p = 0.065. En CAU < 1000 g, Wright 45% y Shukla 42.9%, p = 0.63. En CAU con peso > 1000 g, Wright 80% y Shukla 57.1%, p = 0.23. Conclusiones: La colocación del CVU fue 13% mejor con la fórmula de Wright. La fórmula de Wright superó en el 29% la colocación del CVU en los neonatos > 1000 g en comparación con la de Shukla, aunque no hubo diferencia significativa debido al tamaño de la muestra.

Feasibility of Ultrasound-Guided, Peripherally Inserted Central Catheter Placement at the Bedside in a Communicable-Disease Isolation Unit.

BACKGROUND: Previous studies have investigated the safety of peripherally inserted central catheters (PICCs) in the intensive care unit (ICU). However, it remains uncertain whether PICC placement can be successfully carried out in settings with limited resources and a challenging environment for procedures, such as communicable-disease isolation units (CDIUs). METHODS: This study investigated the safety of PICCs in patients admitted to CDIUs. These researchers used a handheld portable ultrasound device (PUD) to guide venous access and confirmed catheter-tip location with electrocardiography (ECG) or portable chest radiography. RESULTS: Among 74 patients, the basilic vein and the right arm were the most common access site and location, respectively. The incidence of malposition was significantly higher with chest radiography compared to ECG (52.4% vs. 2.0%, p < 0.001). CONCLUSIONS: Using a handheld PUD to place PICCs at the bedside and confirming the tip location with ECG is a feasible option for CDIU patients.

The Association of Vasopressor Administration through a Midline Catheter with Catheter-related Complications.

Rationale: Little is known about the safety of infusing vasopressors through a midline catheter. Objectives: To evaluate safety outcomes after vasopressor administration through a midline. Methods: We conducted a cohort study of adults admitted to 39 hospitals in Michigan (December 2017-March 2022) who received vasopressors while either a midline or peripherally inserted central catheter (PICC) was in place. Patients receiving vasopressors through a midline were compared with those receiving vasopressors through a PICC and, separately, to those with midlines in place but who received vasopressors through a different catheter. We used descriptive statistics to characterize and compare cohort characteristics. Multivariable mixed effects logistic regression models were fit to determine the association between vasopressor administration through a midline with outcomes, primarily catheter-related complications (bloodstream infection, superficial thrombophlebitis, exit site infection, or catheter occlusion). Results: Our cohort included 287 patients with midlines through which vasopressors were administered, 1,660 with PICCs through which vasopressors were administered, and 884 patients with midlines who received vasopressors through a separate catheter. Age (median [interquartile range]: 68.7 [58.6-75.7], 66.6 [57.1-75.0], and 67.6 [58.7-75.8] yr) and gender (percentage female: 50.5%, 47.3%, and 43.8%) were similar in all groups. The frequency of catheter-related complications was lower in patients with midlines used for vasopressors than PICCs used for vasopressors (5.2% vs. 13.4%; P < 0.001) but similar to midlines with vasopressor administration through a different device (5.2% vs. 6.3%; P = 0.49). After adjustment, administration of vasopressors through a midline was not associated with catheter-related complications compared with PICCs with vasopressors (adjusted odds ratios [aOR], 0.65 [95% confidence interval, 0.31-1.33]; P = 0.23) or midlines with vasopressors elsewhere (aOR, 0.85 [0.46-1.58]; P = 0.59). Midlines used for vasopressors were associated with greater risk of systemic thromboembolism (vs. PICCs with vasopressors: aOR, 2.69 [1.31-5.49]; P = 0.008; vs. midlines with vasopressors elsewhere: aOR, 2.42 [1.29-4.54]; P = 0.008) but not thromboses restricted to the ipsilateral upper extremity (vs. PICCs with vasopressors: aOR, 2.35 [0.83-6.63]; P = 0.10; model did not converge for vs. midlines with vasopressors elsewhere). Conclusions: We found no significant association of vasopressor administration through a midline with catheter-related complications. However, we identified increased odds of systemic (but not ipsilateral upper extremity) venous thromboembolism warranting further evaluation.

Ultrasound-Guided Short-Axis Out-of-Plane Approach With or Without Dynamic Needle-Tip Positioning for Peripheral Venous Catheterization in Pediatric Patients: A Systematic Review With Network Meta-Analysis.

OBJECTIVES: To compare the efficacy of the ultrasound-guided approach with and without dynamic needle-tip positioning and the palpation technique regarding success for peripheral venous catheterization in children. DESIGN: A systematic review with network meta-analysis. SETTING: Databases of MEDLINE (via PubMed) and Cochrane Central Register of Controlled Trials. PARTICIPANTS: Patients (<18 years) undergoing peripheral venous catheter insertion. INTERVENTIONS: Randomized clinical trials were included to compare the following techniques: the ultrasound-guided short-axis out-of-plane approach with dynamic needle-tip positioning, the approach without dynamic needle-tip positioning, and the palpation technique. MEASUREMENTS AND MAIN RESULTS: The outcomes were first-attempt and overall success rates. Eight studies were included in the qualitative analyses. According to the estimate of network comparison, dynamic needle-tip positioning was associated with higher first-attempt (risk ratio [RR] 1.67; 95% CI 1.33-2.09) and overall success rates (RR 1.25; 95% CI 1.08-1.44) than palpation. The approach without dynamic needle-tip positioning was not associated with higher first-attempt (RR 1.17; 95% CI 0.91-1.49) and overall success rates (RR 1.10; 95% CI 0.90-1.33) than palpation. Compared to the approach without dynamic needle-tip positioning, dynamic needle-tip positioning was associated with a higher first-attempt success rate (RR 1.43; 95% CI 1.07-1.92), but not a higher overall success rate (RR 1.14; 95% CI 0.92-1.41). CONCLUSIONS: Dynamic needle-tip positioning is efficacious for peripheral venous catheterization in children. It would be better to include dynamic needle-tip positioning for the ultrasound-guided short-axis out-of-plane approach.

Cost-effectiveness analysis of arterial catheter insertion on robotic-assisted laparoscopic prostatectomy.

INTRODUCTION: To evaluate the utility, outcomes, and cost of arterial line placement in a single institution cohort of patients undergoing robotic-assisted laparoscopic prostatectomy (RALP). MATERIALS AND METHODS: A retrospective chart review was performed at a large tertiary care center from July 2018 through January 2021. Hospital costs and cost-effective analysis was performed on patients with and without arterial line placement. Means with standard deviations were used to report continuous variables, while numbers and percentages were utilized to describe categorical variables. T-tests and Chi-square tests compared categorical and continuous variables across study cohorts, respectively. Multivariable analyses were used to examine the association between A-line placement and outcomes as mentioned above adjusting for the effect of other co-variables. RESULTS: Among the 296 included patients, 138 (46.6%) had arterial lines. No preoperative patient characteristic predicted arterial line placement. Rates of complications and re-admissions were not statistically significant between the two groups. Arterial line use was associated with higher volumes of intraoperative fluid administration, as well as a longer hospital length of stay. Total cost and operative time did not significantly differ between cohorts, but arterial line placement increased variability of these factors. CONCLUSION: The use of arterial lines in patients undergoing RALP is not necessarily guideline-driven and does not decrease the rate of perioperative complications. However, it is associated with longer length of stay and increases variability in charge. These data show that the surgical team and anesthesia team should critically evaluate the need for arterial line placement in patients undergoing RALP.

UltraSound guided PEripheral Catheterization increases first-atTempt success RAte in hospitalized patients when compared with conventional technique: SPECTRA - Randomized Clinical Trial.

BACKGROUND: Peripheral intravenous catheter (PIVC) insertion is the most common invasive procedure in the hospital setting. Ultrasound guided PIVC insertion in specific populations and settings has shown patient care benefits. OBJECTIVE: To compare the success rate of first attempts of ultrasound guided PIVC insertion performed by nurse specialists with conventional PIVC insertion performed by nurse assistants. METHOD: Randomized, controlled, single-center clinical trial registered on the ClinicalTrials.gov platform under registration NTC04853264, conducted at a public university hospital from June to September 2021. Adult patients hospitalized in clinical inpatient units with an indication for intravenous therapy compatible with a peripheral venous network were included. Participants in the intervention group (IG) received ultrasound guided PIVC performed by nurse specialists from the vascular access team, while those in the control group (CG) received conventional PIVC by nurse assistants. RESULTS: The study included a total of 166 patients: IG (n = 82) and CG (n = 84), mean age 59.5 ± 16.5 years, mostly women (n = 104, 62.7%) and white (n = 136, 81.9%). Success rate on the first attempt of PIVC insertion in IG was 90.2% and in CG was 35.7% (p < 0.001), with a relative risk of 2.5 (95% CI 1.88-3.40) for success in IG versus CG. Overall assertiveness rate was 100% in IG and 71.4% in CG. Regarding procedure performance time, the medians in IG and CG were 5 (4-7) and 10 (6-27.5) min respectively (p < 0.001). As for the incidence of negative composite outcomes, IG had lower rates compared to CG, 39% versus 66.7% (p < 0.001), generating a 42% lower probability of negative outcomes in IG, 0.58 (95% CI: 0.43-0.80). CONCLUSION(S): Successful first-try insertion was higher in the group receiving ultrasound-guided PIVC. Moreover, there were no insertion failures and IG presented lower insertion time rates and incidence of unfavorable outcomes.
