after lumbar puncture

"Doctor, after a lumbar puncture in one bed, I don't want to lie down for 6 hours." Usually, we ask patients to lie on their backs for 6 hours after lumbar puncture, in order to avoid postoperative headaches, which is the legendary Lie to win. The principle is that short-term bed rest can reduce the hydrostatic pressure of the cerebrospinal fluid on the dura mater surface, accelerate the spontaneous healing of dural wounds, and reduce the occurrence of subdural hematoma (according to literature, subdural hematoma after lumbar puncture). The incidence of hematoma is about 37%). Therefore, if the patient does not comply with the doctor's advice, we will persuade the patient to lie down for 6 hours after the operation, even at the risk of the patient not giving a good review. But does it have to be 6 hours? Do you have to lie down?

Studies have shown that there is no difference in the incidence of headache after lumbar puncture between 1 hour and 6 hours of postoperative bed rest, and prolonged bed rest even increases the incidence of orthostatic headache and venous thrombosis. Some data even point out that it is not necessary to stay in bed after lumbar puncture, and it is also feasible for patients to say to themselves "what to sleep and wake up to" after surgery, but they should be cautious. As for the posture of bed rest, there is still controversy in the academic world.

However, some studies have pointed out that the effect of different bed positions is similar, and if the patient has suffered a headache after lumbar puncture, the patient can be left to unlock various sleeping positions while lying down. In addition, there is no strong literature support for the idea of drinking more water after surgery.
