The main reason for lying down for 6 hours after lumbar anesthesia is to prevent low cranial pressure headache.
Before doing lumbar anesthesia to release a certain amount of cerebrospinal fluid, cerebrospinal fluid outflow may lead to a decrease in intracranial pressure, if this time immediately sit up or stand up, it may lead to low cranial pressure headache.
After lumbar anesthesia is performed, because the volume of cerebrospinal fluid released has not completely returned to normal, it is recommended that the patient should lie down for more than 6 hours, when the cerebrospinal fluid will be produced through the choroid plexus in the lateral ventricles of the human brain, and the volume will be gradually restored.
After lumbar anesthesia, it is recommended that patients should follow the doctor’s instructions to take the appropriate position to avoid inducing low cranial pressure headache, which will bring pain to the patient, and communicate with the doctor in time if there is any discomfort after the operation.
