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...

Catheter Based Intravenous Injection of Experimental Agents: A Technique for Delivering Experimental Agents Intravenously Through Jugular Vein in Mouse Model
0 Views •
2025
In this video, we describe a method for implanting a catheter into the jugular vein of a mouse model through which experimental agents such as drugs and tracer dyes can be delivered intravenously in vivo. Such an arrangement when connected to other systems can also be used for monitoring hemodynamics and blood sampling.

We describe a novel surgical method for catheterizing 'intestinal loops' within the ileum of sheep. Once animals have recovered from surgery and have cleared antibiotics and analgesics, multiple treatments can be deposited directly in loops via the catheters.

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

The use of domestic and miniature pigs in science has increased significantly in recent years. By demonstrating how to perform intubation, transurethral bladder catheterization, femoral artery and vein catheterization, as well as transcardial perfusion, we aim to further increase the value of Göttingen minipigs in biomedical research.
FAQs
Because the catheter provides direct vascular access, administered medication enters the circulation without depending on gastrointestinal absorption. This makes the route useful when oral absorption is inadequate or treatment must begin quickly. Direct access also supports controlled delivery through an infusion line or syringe, helping pharmacologists administer a measured dose and observe its systemic effects.
Intravenous delivery allows medication to be administered in a controlled manner through an infusion line or syringe. This control is important when researchers need reliable systemic exposure or carefully timed administration. Compared with situations in which oral absorption may be inadequate, the route offers a dependable way to relate the delivered dose to observed pharmacological responses.
Stable vascular access permits both administration and blood sampling during pharmacokinetic studies. Investigators can deliver a medication and obtain blood samples to examine how exposure changes over time. This paired capability helps connect administered treatment with measured circulating drug levels, supporting evaluation of drug behavior under controlled experimental conditions.
Important complications include infiltration, infection, phlebitis, and accidental dislodgment. Infiltration can interfere with intended delivery, while infection and phlebitis can affect the condition of the vessel and surrounding tissue. Dislodgment may interrupt administration. Careful technique and continued attention to the catheter help reduce these risks during therapy or research procedures.
The process begins with venipuncture using a needle to access a vein. Once the catheter enters the vessel, it is advanced while the needle is removed. The remaining flexible catheter then connects to an infusion line or syringe for controlled administration. This sequence creates usable vascular access while avoiding continued needle-based delivery.
This route is particularly relevant when oral absorption is inadequate or when immediate treatment is required. Direct vascular access supports rapid systemic exposure and controlled dosing, making it useful for medication administration and fluid therapy. Its value depends on maintaining access safely, because complications such as infiltration, infection, phlebitis, or dislodgment can disrupt intended treatment.
Beyond administering medications, the catheter can support fluid therapy, delivery of blood products, blood sampling, and pharmacokinetic studies. These applications make the technique useful in both clinical treatment and pharmacology research. The same vascular access can therefore support therapeutic delivery, specimen collection, or controlled investigation of drug exposure, provided careful technique is maintained.
