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...

Intraduodenal Cannulation in a Rat Model for Immunopathology Studies

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.

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.

This manuscript describes a simple and reproducible protocol for isolation of intracerebral arterioles (a group of blood vessels encompassing parenchymal arterioles, penetrating arterioles and pre-capillary arterioles) from mice, to be used in pressure myography, immunofluorescence, biochemistry, and molecular studies.
FAQs
Blood return confirms that the needle has entered the vein before the flexible catheter is advanced. This confirmation helps the clinician distinguish vascular entry from incorrect positioning and supports the next step of sliding the catheter forward while withdrawing the needle. It therefore links visual confirmation with safe establishment of temporary access.
The needle provides the rigidity needed to pass through the skin and enter the vein, while the flexible catheter remains in place for treatment. After blood return confirms venous entry, the catheter is advanced and the needle withdrawn. This arrangement leaves a less rigid device in the vessel for delivering fluids, medications, or blood products.
Aseptic technique, appropriate site selection, secure fixation, and ongoing monitoring work together to reduce problems. These measures address different risks: asepsis helps limit infection, fixation helps prevent accidental dislodgement, and monitoring supports recognition of infiltration or phlebitis. Using all four principles is more comprehensive than relying on catheter insertion alone.
The principal complications identified for this technique are infiltration, phlebitis, infection, and accidental dislodgement. Monitoring is important because successful insertion does not guarantee that access will remain safe or functional. Continued observation, together with secure fixation and appropriate site selection, helps support patient care and reduce the likelihood that these problems will compromise access.
Peripheral cannulation can provide access for intravenous fluids, medications, and blood products. In selected circumstances, the same access may support blood sampling or contrast administration. The specific use depends on the care being delivered, but each application relies on maintaining a correctly positioned and monitored catheter for temporary vascular access.
The workflow uses a tourniquet, a needle, and a short flexible catheter, with aseptic technique applied during insertion. After venous entry is confirmed by blood return, the catheter is advanced and the needle removed. Secure fixation then helps maintain placement, while monitoring addresses complications during subsequent use.
It gives clinicians a practical route for delivering several commonly required treatments and for supporting selected sampling or contrast procedures. Because the access is temporary, clinicians must combine technical insertion with site selection, secure fixation, and monitoring. This combination makes the technique relevant across patient care while emphasizing safe maintenance after placement.
