Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT Central venous access devices (CVAD), commonly known as central lines or central catheters, are large-bore intravenous (IV) catheters that are introduced into the central circulation. Typically, CVADs terminate in the superior vena cava, just outside of the right atrium of the heart, but they may also terminate in any one of the great veins (i.e., aorta, inferior vena cava, brachiocephalic...

In pandemic times, medical staff is becoming a key resource in fighting the infection. To achieve the best medical care, relevant techniques and procedures have to be taught to medical staff while reducing the risk of infection. Intensive care medical treatment can necessitate central venous catheters due to different indications like vasopressor therapy or treatment of the patient with vein irrigating substances. This video shows the placement of central venous catheters for intensive care...

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...

FAQs
Venous blood return provides an immediate procedural checkpoint: it indicates that the needle or catheter has entered a vein before the device is used for therapy, sampling, or monitoring. The catheter can then be secured and connected to appropriate tubing, creating a stable pathway while helping the clinician verify that placement is suitable for the intended use.
Device and site selection should match the clinical task rather than follow a single standard choice. Treatment duration, the properties of the fluid being delivered, and the patient’s condition guide whether clinicians use peripheral or central venous access. Matching these factors supports reliable delivery and helps avoid choosing an access arrangement unsuited to the therapy.
Aseptic practice is a central control for preventable complications during venous access. Keeping the procedure aseptic helps reduce the possibility of infection while the skin is traversed and the pathway remains in use. This principle matters across short-term interventions and ongoing therapy because infection is one of the complications associated with venous access procedures.
Safety assessment must account for infiltration, infection, bleeding, and thrombosis, because each represents a different complication associated with venous access. The overview links prevention to several controllable elements: appropriate site and device selection, confirmation through blood return, securement, and aseptic practice. Together, these measures support safer ongoing use of the established pathway.
A basic setup includes a needle or catheter for entering the vein, a means of confirming venous blood return, securement for keeping the catheter in place, and tubing for connection to the intended therapy or monitoring system. The selected device and connected components should correspond to treatment duration, fluid properties, and patient condition.
Clinical teams choose this approach whenever a dependable venous pathway is needed for a defined purpose. Supported uses include administering therapy, obtaining blood, monitoring patients, emergency care, anesthesia, infusion therapy, transfusion, and diagnostic sampling. The required duration and the patient’s condition influence how access is planned, so the technique serves both urgent and continuing clinical needs.
In clinical practice, venous access technique links a physical procedure with decisions about patient care. It provides the route through which therapies and transfusions are delivered, blood is sampled for diagnosis, and monitoring can be supported. Its value depends not only on entering the vein, but also on maintaining a secure, appropriate, and aseptic pathway for the planned use.
