Discussion

Simulation analysis compares pulsatile flushing with differing catheter sizes, suggesting implications for nursing education.

Pulsatile flushing improved peripheral intravenous catheter patency, demonstrating effective methods for nurses.
Higher infusion volumes with optimal timing enhanced sodium chloride velocity and volume ratios, positively affecting perfusion.
Simulation analysis assessed flushing effects across 20G, 22G, and 24G catheter sizes indicate safety and efficacy.
Findings inform evidence-based nursing practices, highlighting the need for standardized flushing procedures and nurse training.

Kim et al. (2025) studied this question.
