Is this trial a fit for you?

Likely a good fit

Adults 18–75 years old undergoing first-time tunneled PICC placement with 4Fr single-lumen catheters and able to consent.

Probably not a fit

Patients with coagulation dysfunction, BMI below 18.5, pregnancy, lower-extremity access, or catheter allergies may not benefit.

What this trial studies

This prospective randomized trial compares one-needle versus two-needle tunneling methods used during tunneled PICC catheter placement. Adults aged 18–75 undergoing their first tunneled PICC with a 4Fr single-lumen catheter are randomized to either technique. The goal is to determine which method minimizes catheter-related complications while maintaining safety. The study is conducted at Sun Yat-sen University Cancer Center in Guangzhou and is led by Sun Yat-sen University with no listed collaborators. Participants must meet specific health and consent criteria and will receive standard PICC care and follow-up.

Why it matters

Potential benefit: If successful, the preferred tunneling method could reduce complications and improve outcomes for patients needing long-term PICCs.

How similar studies have gone: Previous research on tunneling techniques in PICC lines has explored safety and infection, but direct randomized comparisons are limited, making this study relatively novel in its direct head-to-head design.
