The process involves obtaining a blood sample from a peripherally inserted central catheter. This method is typically employed when frequent blood sampling is required or when peripheral veins are difficult to access. A trained healthcare professional performs the procedure, adhering to strict sterile protocols to minimize the risk of infection and ensure accurate laboratory results. For example, a patient requiring daily blood tests due to medication monitoring might benefit from this approach.
The utility of this method lies in its ability to reduce patient discomfort associated with repeated venipunctures and preserve peripheral venous access for other necessary treatments. Its adoption has grown alongside the increasing prevalence of long-term intravenous therapies and the need for reliable and consistent blood sampling. Historically, central lines were primarily used for this purpose, but the development and refinement of PICC lines offered a less invasive alternative with fewer associated complications.
The subsequent sections will delve into the specific steps involved in the procedure, potential complications and their management, and best practices for ensuring patient safety and optimal outcomes. This discussion will also cover appropriate indications for its use and compare it with other blood sampling techniques.
