Which technique might be used for vascular access in a hypovolemic patient with collapsed veins?

In a hypovolemic patient with collapsed veins, central venous catheterization using the Seldinger technique is an effective method for vascular access. This technique allows for direct access to larger central veins, which are less likely to collapse, even in the presence of significant hypovolemia. The Seldinger technique involves the insertion of a thin needle into the vein, followed by the placement of a guidewire through the needle. Once the guidewire is in place, the needle is removed, and a catheter can be threaded over the wire into the vein.

This approach is particularly advantageous in cases of fluid resuscitation or the need for medication administration when peripheral intravenous access is difficult or impossible. The central veins allow for larger volumes of fluids or medications to be administered quickly, which is crucial in a hypovolemic patient who may be in a critical condition.

In contrast, the peripheral intravenous approach is typically less effective in such patients, as their veins may be collapsed or difficult to visualize and puncture. Although intraosseous access is another alternative that can be utilized in emergencies, especially when venous access fails, it is generally considered a secondary option to central venous access in situations requiring rapid volume resuscitation.
