Contraindications Of Lumbar Puncture Needles

The patient's position during lumbar puncture can affect the patient's cardiopulmonary function, so patients with a certain degree of cardiopulmonary dysfunction should avoid lumbar puncture. The following patients should also avoid this operation, including patients with signs of cerebral herniation, patients with initial cerebral herniation due to elevated intracranial pressure, patients with possible elevated intracranial pressure and patients with focal neurological symptoms . If the physician has concerns about performing a lumbar puncture, the patient should be examined by computed tomography (CT) of the head before the operation, but CT may not be able to determine whether the patient has signs of increased intracranial pressure. Coagulation disorders can increase the risk of spinal cord hematomas, but it is still unclear what degree of clotting disorders will increase the risk of spinal cord hematomas. For patients who have previously undergone lumbar surgery, if an interventional radiologist uses imaging techniques to perform a lumbar puncture, it may increase the success rate of the operation.
