He became delirious, then violent, yelling and pushing when nurses tried to insert an IV into his arm. Only after sedation was a physician able to slide a long needle between two vertebra in the small of his back and extract a few drops of cerebrospinal fluid.

In healthy individuals, it is clear and quick flowing, moving with an almost silky rush through a needle.
