What are the steps of lumbar puncture

Lumbar puncture first needs to rule out contraindications for lumbar puncture. If suitable for a lumbar puncture, the puncture steps are as follows:

First, determine the body position, generally require the patient to take a lateral position, and then extremely flex the knees and hips, so that the waist can be completely exposed and the lumbar intervertebral space can be increased.

Second, select the puncture point, generally take the intersection of the line connecting the highest points of the bilateral iliac spines and the posterior median as the puncture point.

The third pair of puncture points were anesthetized layer by layer.

Fourth, use the puncture needle to slowly insert the needle until the pillow feels a clear sense of failure. At this time, the needle core can be pulled out, and the cerebrospinal fluid can be seen to flow out. Bandage with gauze and then ask the patient to lie down for more than six hours.
