Insights
Running a slow continuous infusion to keep veins open (TKVO) did not extend peripheral intravenous (PIV) catheter patency compared to saline lock in pediatric patients. Older age was associated with longer PIV catheter duration.
Area of Science:
- Pediatric Nursing
- Intravenous Therapy
- Clinical Practice Guidelines
Background:
- Peripheral intravenous (PIV) catheter insertion is a common but potentially painful procedure in pediatric care.
- Maintaining PIV catheter patency is crucial for effective treatment delivery and reducing patient discomfort.
- Current practices for maintaining PIV patency include saline lock and continuous infusions to keep veins open (TKVO).
Purpose of the Study:
- To compare the effectiveness of saline lock versus TKVO infusions in prolonging PIV catheter patency in pediatric patients.
- To identify factors influencing PIV catheter dwell time in a pediatric setting.
Main Methods:
- Retrospective chart review of pediatric patients with PIV catheters at a regional hospital.
- Data abstraction included patient demographics, catheter characteristics, and time spent on therapeutic infusions, TKVO, or saline lock.
- Statistical analysis compared PIV patency duration based on TKVO use, gender, and age.
Main Results:
- Of 189 PIVs meeting inclusion criteria, the method of maintaining patency (TKVO vs. saline lock) did not significantly impact total PIV catheter duration (P=0.33).
- Patient gender did not influence PIV patency.
- Older patient age was significantly associated with increased PIV catheter patency duration (P=0.028).
Conclusions:
- TKVO infusions are not superior to saline lock for maintaining PIV catheter patency in the pediatric population.
- While age is a factor in PIV dwell time, interventions should focus on efficient catheter management strategies.
- Further research may explore other methods to optimize PIV catheter longevity in children.
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.
