Which vein is commonly referred to as the Houseman's friend vein?

The median cubital vein is commonly referred to as the "Houseman's friend vein." This vein has a prominent and superficial location at the elbow, making it easily accessible for venipuncture. It serves as a convenient site for drawing blood or administering IV medications, which is especially helpful for junior doctors or house officers engaging in routine venous access.

The median cubital vein typically connects the cephalic and basilic veins, providing a stable point that doesn't change position with movement, adding to its practicality for medical professionals in various settings. This characteristic, along with its size and location, contributes to its reputation for being a reliable choice for venous access, which is why it's fondly dubbed the Houseman's friend vein.

In contrast, the subclavian vein, while also significant for vascular access, is not as easily visualized or accessed as the median cubital vein. The cephalic and basilic veins, though important, tend to be less favored for routine blood draws due to their deeper or more variable positions, which can complicate access.
