Post-dural-puncture headache (PDPH) is a complication of puncture of the dura mater (one of the membranes around the brain and spinal cord).[3] The headache is severe and described as "searing and spreading like hot metal", involving the back and front of the head and spreading to the neck and shoulders, sometimes involving neck stiffness. It is exacerbated by movement and sitting or standing and is relieved to some degree by lying down. Nausea, vomiting, pain in arms and legs, hearing loss, tinnitus, vertigo, dizziness and paraesthesia of the scalp are also common.[3]
PDPH is a common side effect of lumbar puncture and spinal anesthesia. Leakage of cerebrospinal fluid causes reduced fluid pressure in the brain and spinal cord. Onset occurs within two days in 66% of cases and three days in 90%. It occurs so rarely immediately after puncture that other possible causes should be investigated when it does.[3]
Using a pencil-point needle rather than a cutting spinal needle decreases the risk of developing PDPH.[4][1] Smaller needle gauges decrease the odds of PDPH, but make it more challenging to perform the procedure successfully.[3][1] The needle with the lowest PDPH rate and highest succession rate is the 26G pencil-point needle.[5] Its estimated PDPH rate is between 2% and 10%.[1]
