What Are The Risks Of Spinal Puncture?

For spinal puncture, lumbar puncture is a common clinical examination method. It is mainly used to extract a small amount of cerebral effusion through lumbar puncture to determine whether there is hemorrhagic or infectious diseases. It can also be used to judge whether intracranial pressure is normal through lumbar puncture. However, lumbar puncture is an invasive operation and has certain risks, mainly manifested in the following two aspects:

First, if the aseptic operation of lumbar puncture is not strict, it may lead to infection of the punctor. If the surrounding blood vessels are damaged, a subcutaneous hematoma may result. If the puncture site is too deep, it can also damage the deep venous plexus and cause bleeding.

Second, if the cerebrospinal fluid extraction speed is too fast or the intracranial pressure itself is relatively high during lumbar puncture, the intracranial pressure will fluctuate sharply, resulting in cerebral hernia, which may endanger the patient's life in serious cases.
