Catheter Insertion

Catheter insertion is a medical procedure that places a thin, flexible tube into a body cavity, vessel, or duct to drain fluids, deliver treatments, or monitor physiological conditions. The catheter advances through a selected anatomical pathway under aseptic conditions, and its position is maintained so fluids can move in or out without damaging surrounding tissue. In biology and biomedical research, catheter insertion supports urine collection, vascular access, pressure measurement, and targeted administration of drugs or contrast agents. Proper technique reduces contamination, trauma, blockage, and infection, making catheter-based procedures valuable for clinical care, experimental studies, and understanding organ function.

2023

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...

Central Venous Catheter Insertion: Subclavian Vein

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations for hemodynamic monitoring, medication delivery, and blood sampling. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the femoral vein. Central venous access via the subclavian vein has several advantages over other possible locations. The subclavian...
