2023
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...

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.

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.
FAQs
The Seldinger technique establishes access in stages: a needle first enters the artery, a guidewire then advances through the needle, and the catheter follows the wire into position. After the needle is removed, the catheter can be secured and connected to monitoring equipment. This sequence helps organize the access process and supports stable arterial sampling or pressure monitoring.
The subclavian artery lies beneath the clavicle and close to the pleura and brachial plexus. Precise localization therefore helps direct the needle toward the intended vessel while limiting injury to nearby structures. Its anatomical position also explains why clinicians must consider complications such as pneumothorax, bleeding, thrombosis, and ischemia during and after access.
Assessment should include bleeding, thrombosis, ischemia, and pneumothorax because the catheterized artery is adjacent to the pleura and important neurovascular structures. These risks provide a clinical reason for careful placement, securement, and follow-up rather than treating catheter insertion as the endpoint. Monitoring for these outcomes is relevant across critical care, anesthesia, vascular surgery, and interventional medicine.
The procedure begins with anatomical localization and needle puncture of the subclavian artery. A guidewire is advanced through the needle, after which the catheter is passed over the wire. The access system is then secured and connected to monitoring equipment. Each stage depends on maintaining accurate vessel access and recognizing the nearby pleural and neurovascular anatomy.
This access can support several clinical tasks: obtaining arterial blood samples, monitoring blood pressure, and supporting endovascular procedures. The appropriate use depends on the intended need for arterial access rather than on a single specialty. Its relevance to critical care and anesthesia includes monitoring, while vascular surgery and interventional medicine may use it in procedural contexts.
In medicine, the technique provides a route for direct arterial sampling and blood-pressure monitoring, while its catheter access can also support endovascular procedures. These functions make it relevant to critical care, anesthesia, vascular surgery, and interventional medicine. Because the access site is anatomically constrained, its clinical value must be balanced against bleeding, thrombosis, ischemia, and pneumothorax risks.
