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...

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
Venous blood return confirms that the needle and catheter have entered a vein, providing the key procedural cue to stop advancing the needle and advance the catheter instead. Once positioned, the catheter remains as the access device while the needle is removed, allowing temporary bloodstream access for the intended clinical task.
Site selection, aseptic preparation, and stabilization address different requirements. Selecting an appropriate peripheral vein supports access, aseptic technique helps limit contamination, and stabilization keeps the catheter from shifting or becoming dislodged. Together with flushing and ongoing observation, these measures support reliable access and help reduce infection, infiltration, phlebitis, and accidental dislodgement.
Flushing is one of the post-placement practices identified for maintaining usable access. It is performed alongside catheter stabilization and monitoring rather than treated as a substitute for either. In the clinical workflow, these measures help reduce complications including infiltration, phlebitis, infection, and accidental dislodgement while the catheter remains available for patient care.
After venous blood return confirms entry, the catheter is advanced into the vein, the needle is removed, and the device is secured. Subsequent flushing and monitoring complete immediate management. This sequence separates access placement from access maintenance and helps preserve temporary access for fluids, medications, blood products, contrast agents, or sampling.
Clinicians use this access for several distinct purposes: administering fluids, medications, blood products, and contrast agents, or obtaining blood samples. The appropriate use depends on the patient-care task requiring temporary bloodstream access. This range makes the technique relevant across treatment delivery, diagnostic sampling, and procedures involving contrast.
Monitoring should include the complications identified for this technique: infiltration, phlebitis, infection, and accidental dislodgement. Observation is not an isolated final step; it works with proper site selection, catheter stabilization, and flushing. This continuing attention helps clinicians recognize problems with the access and support ongoing patient care.
