Comparison of Ultrasound-Guided 10-cm Midline Catheter Versus 4.78-cm Long Peripheral IV for Difficult Vein Access in Emergency Department Patients

What this Trial Is About

This research aims to compare two types of intravenous catheters used in emergency department patients who have veins that are difficult to access for intravenous IV treatment. The study focuses on comparing a 10-centimeter single lumen midline catheter with a 4.78-centimeter long peripheral IV catheter to see which device stays functional longer and has fewer complications. Difficult IV access can delay treatment, so finding the better catheter could improve care delivery for these patients. Participants will be randomly assigned to receive either the long peripheral IV catheter or the midline catheter. Both devices are inserted using ultrasound guidance to visualize veins and ensure proper placement. The midline catheter uses a guidewire technique to assist insertion, while the long peripheral IV does not. The study devices are standard care and approved for use. Insertion is performed by trained clinicians in the emergency department, and detailed ultrasound images will be taken during placement. During the study, participants will be followed from the time of catheter placement through up to 28 days after removal. Researchers will collect data on catheter dwell time, complications, and patient and provider satisfaction using surveys and medical records. Arm measurements, catheter position, and time taken for device placement will also be recorded. Participants will be monitored daily while hospitalized and contacted after discharge to assess outcomes and any issues related to catheter use.
