Insights

Mini-midline catheters (Mini-MCs) offer longer dwell times and fewer complications than peripheral intravenous catheters (PIVCs) in children with digestive diseases. This suggests Mini-MCs are a suitable alternative for short-term IV therapy.

Area of Science:

  • Pediatric Gastroenterology
  • Vascular Access Devices
  • Medical Devices

Background:

  • Hospitalized children with digestive system diseases often require intravenous (IV) therapy.
  • Choosing the appropriate vascular access device is crucial for effective treatment and patient comfort.
  • Mini-midline catheters (Mini-MCs) and peripheral intravenous catheters (PIVCs) are common options, each with distinct characteristics.

Purpose of the Study:

  • To compare the efficacy and safety of mini-midline catheters (Mini-MCs) versus peripheral intravenous catheters (PIVCs) in pediatric patients hospitalized for digestive system diseases.
  • To evaluate differences in dwell time, complication rates, and unplanned removal between Mini-MCs and PIVCs.

Main Methods:

  • A comparative study involving hospitalized children with digestive system diseases.
  • Participants were assigned either an 8-cm Mini-MC or a 24-gauge PIVC based on patient or guardian preference.
  • Catheter outcomes, including dwell time, complications, and reasons for removal, were systematically monitored.

Main Results:

  • The study included 64 children in the Mini-MC group and 61 in the PIVC group.
  • Mini-MCs demonstrated a significantly longer median dwell time (94 hours) compared to PIVCs.
  • The PIVC group experienced higher overall complication rates and a greater number of unplanned removals.

Conclusions:

  • Mini-midline catheters (Mini-MCs) are associated with superior outcomes, including extended dwell time and reduced complications, when compared to peripheral intravenous catheters (PIVCs) in pediatric patients with digestive diseases.
  • Mini-MCs represent a potentially advantageous option for short-term intravenous therapy in this specific patient population.
