Does the Midline Peripheral Intravenous Catheter Have a Place in Critical Care?

Area of Science:

• Critical care medicine
• Vascular access
• Infusion therapy

Background:

• Preserving vascular health and ensuring safe treatment delivery are key goals of infusion therapy, often complicated in critical care settings.
• The need for long-term peripheral vascular access devices, distinct from central venous catheters, has led to increased use of midline catheters.
• Midline catheters are being reconsidered for their role in reducing risks associated with central catheter-associated bloodstream infections.

Purpose of the Study:

• To comprehensively review the characteristics, benefits, and risks associated with midline catheters.
• To examine the current evidence base for the utilization of midline catheters within critical care environments.

Main Methods:

• Literature review of research on midline catheters and vascular access devices.
• Analysis of safety profiles and clinical evidence regarding midline catheter use.

Main Results:

• Extensive research has significantly advanced understanding of vascular access device selection and midline catheter application.
• Emerging evidence is refining the safety profile of midline catheters, highlighting their potential to support infusion therapy objectives.

Conclusions:

• While research quality varies, a clearer safety profile for midline catheters is developing.
• Midline catheters fill a specific niche but require careful consideration; they are not for infection prevention and are best for peripherally compatible solutions or short-term emergent vesicant therapy.
