Technologies in pediatric vascular access: have we improved success rate in peripheral vein cannulation?

Evaluating Effectiveness of the Use of an Extremity Stabilization Device for Vascular Access Procedures in Pediatrics

The purpose of this study is to evaluate the effectiveness of SafeBoard, a Food and Drug Administration-approved extremity stabilization device, as an assistive method in performing peripherally inserted central catheter procedures on children 0 to 3 years of age. This is a retrospective chart review ( n  = 59) of vascular access procedures where SafeBoard was utilized ( n  = 32 ) in comparison to those procedures which utilized a traditional approach to placement ( n  = 27). Statistical analysis demonstrated significant effect on length of procedure time, number of personnel needed for procedure, and success of placement when SafeBoard was utilized. Obtaining vascular access in pediatrics can be a challenging endeavor. Most young pediatric patients require procedural sedation and/or assistive personnel as a "holder" for successful vascular access placement to occur. An alternative option for extremity stabilization may provide improved workflow and improved placement success, which in turn may positively affect workflow.

Effect of a thin-tipped short bevel needle for peripheral intravenous access on the compressive deformation and displacement of the vein: A preclinical study

BACKGROUND

Peripheral intravenous catheter (PIVC) insertion often fails on the first attempt. Risk factors include small vein size and dehydration, causing vein deformation and displacement due to puncture resistance of the vessel. The authors developed a short, thin-tipped bevel needle and compared its puncture performance with needles of four available PIVCs using an ex vivo model.

METHODS

The PIVC with the thin-tipped short bevel needle was compared to four available PIVCs using an ex vivo model which simulated the cephalic vein of the human forearm. The ex vivo model consisted of a porcine shoulder and porcine internal jugular vein, and was used for evaluation of the rate of vein deformation and vessel displacement during needle insertion.

RESULTS

An ex vivo model was created with a vessel diameter of 2.7-3.7 mm and a depth of 2-5 mm. The thin-tipped short bevel PIVC needle was associated with a significantly lower compressive deformation rate and venous displacement compared to the needles of the other four PIVCs.

CONCLUSION

The thin-tipped short bevel needle induced lower compressive deformation and displacement of the vein than the conventional needles. This needle has the potential to improve the first-attempt success rate of peripheral intravenous catheterization in patients with difficult venous access.

Association between Endotype of Prematurity and Mortality: A Systematic Review, Meta-Analysis, and Meta-Regression

INTRODUCTION

Preterm birth represents the leading cause of neonatal mortality. Pathophysiological pathways, or endotypes, leading to prematurity can be clustered into infection/inflammation and dysfunctional placentation. We aimed to perform a systematic review and meta-analysis exploring the association between these endotypes and risk of mortality during first hospital admission Methods: PROSPERO ID: CRD42020184843. PubMed and Embase were searched for observational studies examining infants with gestational age (GA) ≤34 weeks. Chorioamnionitis represented the infectious-inflammatory endotype, while dysfunctional placentation proxies were hypertensive disorders of pregnancy (HDP) and small for GA (SGA)/intrauterine growth restriction (IUGR). A random-effects model was used to calculate odds ratios (ORs) and 95% confidence intervals. Heterogeneity was studied using random-effects meta-regression analysis.

RESULTS

Of 4,322 potentially relevant studies, 150 (612,580 infants) were included. Meta-analysis showed positive mortality odds for chorioamnionitis (OR: 1.43, 95% confidence interval: 1.25-1.62) and SGA/IUGR (OR: 1.68, 95% confidence interval: 1.38-2.04) but negative mortality odds for HDP (OR 0.74, 95% confidence interval: 0.64-0.86). Chorioamnionitis was associated with a lower GA, while HDP and SGA/IUGR were associated with a higher GA. Meta-regression showed a significant correlation between these differences in GA and mortality odds.

CONCLUSION

Our data suggest that the infectious/inflammatory endotype of prematurity has a greater overall impact on mortality risk as it is the most frequent endotype in the lower GAs. However, when the endotype of placental dysfunction is severe enough to induce growth restriction, it is strongly associated with higher mortality rates even though newborns are more mature.

NURSING CARE IN PERIPHERAL INTRAVENOUS CATHETERIZATION IN HOSPITALIZED CHILDREN: INTEGRATIVE REVIEW

ABSTRACT Objective: to describe nursing care in peripheral intravenous catheterization in hospitalized children. Method: integrative review carried out in November 2020 in LILACS, CINAHL, MEDLINE, SciELO, BDENF and COCHRANE databases. The analysis was constructed from the processes of this review. Results: 19 articles were analyzed, classified according to the level of evidence: level II (5%), level IV (21%), level V (5%), level VI (63%) and level VII (5%). Analytical category "Care for hospitalized child requiring peripheral intravenous catheter". Ultrasound was considered a useful technology. The most used and recommended catheter is the 24 Gauge caliber and the ideal dressing is to use sterile transparent film. Venipuncture in children is more difficult than adults and is often associated with adverse events. Elective catheter replacement is not recommended in children, but there are still doubts. The Difficult Intravenous Access score determines the probability of catheterization failure. Specialized and trained nursing professionals make a difference in this procedure. One should be concerned with pain, using pharmacological and non-pharmacological devices to minimize it. Conclusion: this review contributes to good practices in the care of peripheral intravenous catheterization in children and was based on data on the main technologies used, forms of prevention of adverse events, as well as nursing actions that ensure the safest and least stressful process for children and their families.
