A spinal puncture should be an intradural puncture, also called a lumbar puncture. It is commonly used for intracranial pressure monitoring, examination of cerebrospinal fluid, and anesthesia for lower extremity surgery, and is a relatively common type of examination and treatment operation. Of course, it can be harmful to some degree, but it can be reduced and avoided through standardized operation and treatment. The risk of complications is higher when the patient has scoliosis, herniated discs, or spinal stenosis of the spinal canal. The most serious complications of spinal cord puncture can result in damage to the spinal cord, causing pain, numbness and sensory loss in the area of spinal cord innervation, and even paralysis to varying degrees. If the damage to the spinal cord is severe, the edema gradually moves upward, causing even cardiac and respiratory arrest, with localized pain. Infection in the spinal canal is also a complication of spinal cord puncture. However, there are some diseases for which a spinal tap is necessary to check the cerebrospinal fluid, and there is no alternative. Complications can occur with any invasive procedure, but the chances of them occurring are not very high and should not be taken too seriously.
