Intraduodenal Cannulation in a Rat Model for Immunopathology Studies
0 Views •
2025
This video demonstrates intraduodenal cannulation in a rat model. After anesthetizing the rat, the duodenum is located and a small puncture is created. A J-shaped cannula with a beveled tip is carefully inserted and secured, and the incision is closed. The cannulated rat model enables intra-intestinal infusion for immunopathology studies.

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...

A protocol for the cannulation of the mouse submandibular salivary gland via the Wharton's duct is described. For this experiment, the trypan blue solution is used as a dyer to demonstrate how this technique effectively delivers infusions into the targeted gland, and to suggest the reliability of this new approach as a potential clinical drug/cell therapy for the regeneration of salivary glands.
FAQs
Vessel choice determines what the access can support. Peripheral and central venous routes are suited to fluid and medication delivery, while an arterial route provides continuous blood-pressure monitoring and repeated blood-gas analysis. This distinction links anatomy and vessel type to the clinical purpose of cannulation, rather than treating all access sites as interchangeable.
Anatomical knowledge helps clinicians select a vessel and guide the catheter along an appropriate path. It also supports safer needle placement and more dependable positioning. In practice, vessel selection must be considered alongside the intended use, because access for treatment through a vein has different requirements from access for arterial monitoring or sampling.
Catheter advancement can occur directly after needle entry or over a guidewire. The guidewire provides a pathway that allows the catheter to follow the established vessel access, whereas direct advancement uses the initial needle-created route. Either approach requires attention to position, because reliable monitoring, sampling, or treatment depends on access remaining correctly placed.
Clinicians select the vessel, puncture it with a needle, and advance the catheter either directly or over a guidewire. They then secure the catheter, confirm its position, and maintain sterile conditions. These steps create a controlled sequence from access establishment to dependable use for circulation monitoring, blood sampling, fluid administration, or medication delivery.
Sterile conditions help address infection risk, while securement helps keep the catheter in its intended position during use. Together with position confirmation, these measures support reliable access for monitoring, sampling, or treatment and help prevent problems associated with an unstable or contaminated access site. Bleeding prevention is also an essential safety consideration.
Venous cannulation is appropriate when the clinical goal is to deliver fluids or medications, using either a peripheral or central route. Arterial cannulation is selected when continuous blood-pressure monitoring or repeated blood-gas analysis is needed. The choice therefore follows the required function of the access, whether treatment delivery or ongoing physiological assessment.
