"Mini-MCs were associated with longer dwell time, fewer complications, and reduced unplanned removal compared with PIVCs, and may be a suitable option for short-term intravenous therapy in this population" Jin et al (2026).
Mini-midline catheters versus peripheral intravenous catheters

Abstract:

Objectives: To compare the mini-midline catheters (Mini-MCs) and peripheral intravenous catheters (PIVCs) in hospitalized children with digestive system diseases.

Methods: In this study, children received either an 8-cm Mini-MC or a 24-gauge PIVC based on patient or guardian preference. Catheter outcomes, including dwell time, complications, and unplanned removal, were monitored during the indwelling period.

Results: Sixty-four children received Mini-MCs and 61 received PIVCs. Median dwell time was significantly longer in the Mini-MC group (94 hours; Z = -4.37, P < .01). Kaplan-Meier analysis showed longer catheter survival for Mini-MCs (χ2 = 29.58, P < .001). The PIVC group had higher overall complication rates (χ2 = 8.23, P < .01) and more unplanned removals (χ2 = 9.30, P < .01).

Conclusion: Mini-MCs were associated with longer dwell time, fewer complications, and reduced unplanned removal compared with PIVCs, and may be a suitable option for short-term intravenous therapy in this population.
