Objective: This study aimed to compare the impact of saline lock to running a slow continuous infusion to-keep-vein-open (TKVO) on the total time a peripheral intravenous (PIV) catheter remained patent.
Method: A retrospective chart review of all children admitted to the paediatric ward of a regional hospital in Saskatchewan December 1, 2013 through February 28, 2014. Characteristics of patients with PIV catheters were abstracted from the health records, including patient size, catheter size and site, and total time each PIV catheter spent (i) infusing therapeutic fluids or medications, (ii) running a TKVO infusion, or (iii) saline locked. The duration of catheter patency was compared with the proportion of time that TKVO infusions were run, as well as patient gender and age.
Results: During 375 admissions, there were 189 PIVs which met inclusion criteria. The proportion of nontherapeutic time a PIV catheter spent TKVO compared to saline locked did not affect the total time the PIV catheter was patent (P=0.33). Gender had no influence, but older age, a nonmodifiable factor, was associated with increased time a PIV catheter remained patent (P=0.028).
Discussion: Peripheral intravenous (PIV) catheter insertion can be a painful and traumatic procedure. On the paediatric ward of a regional hospital, TKVO infusions were not superior to saline lock for prolonging PIV catheter patency.

Advances in neonatal medicine over the last several decades have led to improvements in survival for the most fragile and critically ill infants. A mainstay of supporting the health needs of hospitalized infants involves use of peripheral intravenous (PIV) catheters to administer medications, parenteral nutrition, and blood products. However, PIV catheters are not without risks and complications such as infiltration and extravasation.

Background: In 2020, as a result of evidence of demonstrated safety of an initial pilot program, our institution set out to implement a peripheral vasopressor infusion protocol.
Objective: To evaluate the use of peripheral lines for vasopressor administration to reduce placement of unnecessary central lines and central line days.
Methods: This is an Institutional Review Board approved, single center retrospective chart review conducted as pre/post-analysis.

Introduction: Ultrasound guided IV catheter (USGIV) access occurs frequently in Emergency Departments (EDs). This task is often performed using large, expensive, cart-based ultrasound systems (CBUS) which are frequently needed for other ED ultrasound functions and can be cumbersome to use and store. Handheld ultrasounds (HHUs) may be able to meet this need, but it is unknown if they function interchangeably with CBUS for USGIV placement.

Design: Quantitative two-phase, cluster analysis design.
Methods: The study consisted of the following two phases: (1) a quantitative retrospective chart review to evaluate clinician utilisation and preference for vein visualisation technologies and (2) a quantitative prospective design, including a post-discharge retrospective chart review, to confirm utilisation of vein visualisation technologies and factors influencing clinician decision-making.

Background: Ischemic stroke is a leading cause of death and significant long-term disability worldwide. Mechanical thrombectomy is emerging as a standard treatment for eligible patients. As clinical implementation of stent retrieval and aspiration thrombectomy increases, there is a need for physiologically relevant in vitro device efficacy testing.
