Anaesthesia · Regional anaesthesia: ultrasound needle approach

Sample item

In ultrasound-guided blocks, what is the advantage of the in-plane needle approach?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. The whole needle shaft and tip can be seen during advancement

In the in-plane technique, the needle is aligned with the long axis of the ultrasound beam, so the entire shaft and tip are visible. This improves safety by reducing inadvertent puncture of vessels, pleura or nerves. The out-of-plane approach shows only a dot, which may be the shaft rather than the tip.

Option by option

  • A. The whole needle shaft and tip can be seen during advancement (correct)

    Correct. Seeing the full needle allows accurate tip placement.

  • B. The needle does not need to be visualised

    Needle visualisation is the basis of ultrasound-guided blocks.

  • C. Only the needle tip is seen as a dot

    A dot view describes the out-of-plane approach.

  • D. Nerve stimulation becomes unnecessary in all cases

    Stimulation can still be used as an adjunct.
