How Common Are Post-Dural Puncture Headaches in Children?

Patient Presentation
A 9-year-old female came to the emergency room with headache, fever and nucal rigidity. A lumbar puncture was performed with results consistent with viral meningitis. After the lumbar puncture the patient’s headache seemed better when she was lying down but would get worse when she sat up or tried to walk. This was consistent over the next 3 days after which she was referred to a regional children’s hospital for evaluation and management. Upon admission, her fever had resolved after 24 hours and she was able to eat and drink, but intravenous fluids were maintained to ensure adequate hydration. Her headache was described as an occipital headache with some throbbing that occurred when she sat up. She denied vertigo and had minimal back pain at the lumbar puncture site. The family denied any medications other than what had been given in the hospital which included acetaminophen, ibuprofen and ceftriaxone which was stopped after cultures came back negative for bacterial meningitis. The past medical and family history revealed a fully-immunized child and were otherwise non-contributory. The radiologic evaluation from the outside hospital of an MRI of the spine was normal.

The pertinent physical exam showed a tired child in no distress lying in bed. Her vital signs were normal including blood pressure and growth parameters in the 10-25%. HEENT showed no papilledema. Her neurological examination revealed a patient who was alert and oriented x 4 with normal cranial nerves. Her DTRs were +2/+2 with normal strength and tone. Cerebellar maneuvers were normal. Her skin showed a small healing puncture over the lower spine.

The diagnosis of a post-dural puncture headache was made. After discussion with the family, the patient was treated with oral caffeine. Within an hour the patient was able to sit up and walk around the room without a headache. However after being up for about 4-5 hours, the headache returned. The headache resolved with lying recumbent. Caffeine was again given and the patient again was able to sit, walk and play. The headache again seemed to return after about 8 hours but was much less in intensity. Caffeinated beverages were then used along with some acetaminophen to maintain pain control. The patient went home after approximately 36 hours and on followup had complete resolution 2 days later.

Discussion
Post-dural puncture headache or spinal headache as they are often called, are headaches that occur within 7 days of a lumbar puncture and remit within 14 days of the lumbar puncture. They begin or worsen within 15 minutes of being in an upright position and improve or stop within 30 minutes of lying down. The headaches are described as a throbbing, dull and severe pain worse mainly in the occipital area, but can occur with radiation to the eyes, forehead or neck. Nausea, emesis, stiff neck, and visual or auditory changes may also occur. Most spinal headaches occur within 1-2 days of the lumbar puncture and spontaneously resolve after 5 days of headache (range 1-12 days).
The etiology is unknown but it is thought that the lumbar puncture allows a small cerebrospinal fluid leak to occur causing intracranial hypotension, downward sagging of the brain and subsequent pulling on the pain sensitive meninges and large blood vessels. Lumbar puncture techniques which may decrease the risk of spinal headaches include using a small gauge, non-cutting needle, orienting the bevel or opening of the needle parallel to the longitudinal dural fibers and replacement of the stylet before removing the needle.

Treatment usually begins with 1-2 days of supportive therapy including hydration, analgesics and bed rest. Medical treatment may include oral or IV caffeine. An epidural blood patch may also be attempted where ~10-15 ml of autologous blood is placed into the epidural space as close as possible to the lumbar puncture site. The success rate is 75-96%.

Learning Point
One prospective study of children ages 2-16 years showed 27% with some type of headache, 9% with a positional headache and 40% with backaches. Frequency of headaches increased with age, female gender in older patients and those with higher cerebrospinal fluid cell counts.

Other studies cite 2-15% occurence rate for spinal headaches.

Questions for Further Discussion
1. What are the classic cerebrospinal fluid findings for different types of meningitis? see What Are the Initial Cerebrospinal Fluid Findings in Differential Types of Meningitis?
2. Describe the key elements of informed consent?
