About this study
Official title: Peripherally Inserted Central Venous Catheter: Efficacy and Safety
Central venous access is critical for administering intravenous medications, parenteral nutrition, and fluid therapy in intensive care units (ICUs). Peripherally inserted central catheters (PICCs) provide an alternative to traditional centrally placed catheters, but they can be associated with complications such as blood clots (thrombosis), catheter-related infections, and mechanical blockages. The primary purpose of this study is to assess the procedural efficacy, functional lifespan, and complication rates of ultrasound-guided PICCs in critically ill adult patients.
In this prospective observational study, 60 adult ICU patients who require central venous access for at least 5 to 7 days will undergo bedside PICC placement by radiology staff using real-time ultrasound guidance and the modified Seldinger technique. Proper positioning of the catheter tip will be verified by a portable chest radiograph immediately after insertion.
Participants will be monitored daily while the catheter remains in place until line removal, ICU discharge, or death. Surveillance includes daily clinical site inspections, structured laboratory assessments, and scheduled compression Doppler ultrasound scans to check for blood clots in the cannulated arm. If an infection or blockage is suspected, appropriate blood cultures and diagnostic work-ups will be conducted. The gathered data will determine the insertion success rate, functional patency rate, and the overall incidence of complications per 1,000 catheter-days to establish evidence-based guidelines for vascular access in critical care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Critically Ill Patients Receiving PICC | Adult patients (aged 18 years or older) admitted to the intensive care unit requiring central venous access for at least 5 to 7 days for indications such as difficult peripheral access, parenteral nutrition, prolonged intravenous antibiotic therapy, or vasoactive infusions. All enrolled participants undergo bedside ultrasound-guided peripherally inserted central catheter (PICC) placement performed by the Radiology Department using the modified Seldinger technique, with tip position confirmed by post-procedure chest radiograph. Patients are followed daily throughout the catheter dwell period until line removal, ICU discharge, or death to evaluate insertion success, functional patency, and procedural complications including catheter-related bloodstream infections, upper-extremity deep vein thrombosis, and mechanical failures. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With at Least One PICC-Related Complication
Number of patients who experience at least one PICC-related complication (including catheter occlusion, accidental dislodgement, catheter-related bloodstream infection confirmed per CDC/NHSN criteria, or catheter-related venous thrombosis confirmed by Doppler ultrasound) during the catheter dwell period.
Measured: Up to 30 days
