Determining the Correct Purge Volume for Blood Sampling Using PiccLine in Adults A Study in Hospitalized Hematology Patients

What this Trial Is About

Researchers are evaluating the best volume of purge needed for blood sampling through PiccLine systems used by patients receiving therapeutics and nutrition. This trial addresses the lack of consensus on sampling methods and aims to standardize practice by comparing current hospital procedures with established guidelines. The study focuses on patients hospitalized in hematology units who have had a PiccLine placed recently and are receiving infusions. Participants will be randomly assigned to one of two groups one where six consecutive blood tubes are collected through the PiccLine using the usual purge volume, and another where the PiccLine is first rinsed with 10 ml of saline before sample collection. Each participant will also have a peripheral blood sample taken as a reference. The study compares the biological results from the PiccLine samples to those obtained from the peripheral samples. During the study, researchers will collect and analyze blood samples for sodium, potassium, chlorine, creatinine, and glucose levels over two days. Participants are monitored to ensure sample quality and to determine the lowest purge volume that matches peripheral blood results. The trial involves hospital stays in hematology units and requires participants to have given informed consent. The study is expected to continue until May 2026.
