Source: Sharon Bord, MD, Department of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA Placement of an intravenous (IV) catheter is one of the key procedures in medicine. The IV catheter allows patients to receive critical medications, including pain medicine, insulin, antibiotics, blood products, and fluids for rehydration. Additionally, placing an IV catheter allows for blood samples to be obtained, which can be sent to the laboratory for testing and...

(2018)This video demonstrates the procedure for implanting a cannula into the cisterna magna of an anesthetized mouse. The technique involves guiding a needle-mounted cannula through the dura into the inverted triangular cisterna magna and securing it for targeted delivery into the cerebrospinal fluid.

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT Intravenous (IV) fluid administration and peripheral IV catheters (PIVs) may be discontinued for a number of reasons. The most common reason for discontinuing IV fluids is that the patient has returned to normal body fluid volume (euvolemia) and is able to maintain adequate oral fluid intake or is being discharged from the hospital. In addition, the Centers for Disease Control Guidelines...

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...
FAQs
During placement, the needle acts as a guide for the flexible catheter as both enter the vessel. Venous blood return confirms that the catheter has entered the vein. The needle is then withdrawn, leaving the catheter in place so an infusion set or extension line can be connected without retaining the sharp needle in the vessel.
Infiltration, phlebitis, infection, and accidental dislodgement are important site complications. Regular assessment helps identify problems while the cannula is being used. A change at the site may indicate that the catheter is no longer functioning safely or that local tissue is being affected, making ongoing observation an essential part of clinical care.
These measures address different risks. Aseptic technique helps reduce infection during placement and handling, securement helps prevent accidental dislodgement, and regular assessment supports early recognition of infiltration or phlebitis. Used together, they help maintain reliable vascular access while reducing complications that could interrupt treatment or require another cannula.
Placement begins with appropriate vein selection and aseptic preparation. The needle and catheter are advanced into the vein until venous blood return confirms entry. The needle is withdrawn while the catheter remains, after which an infusion set or extension line can be attached. The device is then secured and the site assessed regularly during use.
This form of access supports temporary delivery of several treatments, including fluids, medications, blood products, and contrast agents. The choice depends on the immediate clinical need and the suitability of peripheral venous access. In selected situations, the cannula may also permit blood sampling, extending its usefulness beyond infusion alone.
Yes, blood sampling may be possible in selected situations, although the overview does not present it as a universal use. Its primary clinical role is to provide access for fluids, medications, blood products, or contrast agents. Whether sampling is appropriate depends on the situation and should be considered alongside site condition and safe catheter management.
