A lumbar puncture is a feeling of disappointment in the doctor's hand, not the patient's, right? The roommates insisted that it was the patient who felt a sense of disappointment.

This is for the feeling of the doctor's operation. If the needle insertion position is correct, the puncture needle should enter through the skin in turn. When the puncture needle passes through the ligamentum flavum, the doctor can feel a sense of breakthrough. At this time, the needle core should be pulled out 2mm to observe whether there is cerebrospinal fluid outflow.

suggestions:

If there is a wound during the puncture, it may be slightly bloody. It should be clear and bloodless, unless subarachnoid hemorrhage is present. If the flow of cerebrospinal fluid is not smooth, the needle can be rotated 90 degrees, it is necessary to consider the blockage and other conditions.
