| | An Avoidable Complication of Lumbar Puncture? |
 | | The associated risk of post-lumbar puncture headache was 70% for a 16- to 19-gauge needle, 20% to 40% for a 20- to 22-gauge needle, and 5% to 12% for a 24- to 27-gauge needle. | | | According to the report, patients who had headache before the procedure were not only at greater risk for post-lumbar puncture headache but their headaches usually were more severe and were longer in duration than those of patients who did not have headache prior to or during the lumbar puncture. | | | Two practices that perform a large number of diagnostic lumbar punctures with cutting needles and that document a greater than 10% frequency of severe post-lumbar puncture headache should be recruited to perform independent, double-blind, prospective studies of same-gauge cutting versus noncutting needles. |

| | Lumbar puncture (LP) is the technique of using a needle to withdraw cerebrospinal fluid (CSF) from the spinal canal. | | | Lumbar puncture should be performed only with extreme caution, and only if the benefits are thought to outweigh the risks, in certain conditions. | | | In a lumbar puncture, the area of the spinal column used to obtain the CSF sample is in the lumbar spine, or lower section of the back. |

| | A lumbar puncture must be done with aseptic technique by qualified medical practitioners. | | | In performing a lumbar puncture (in an adult), first the patient is usually placed in a left (or right) lateral position with his/her neck bent in full flexion and knees bent in full flexion up to his/her chest, approximating a fetal position as much as possible. | | | Diagnostic analysis of changes in fluid pressure during lumbar puncture procedures requires both attention to the patient's condition during the procedure and to their medical history. |

| | Lumbar puncture headache (Spinal Headaches) |
| | The size of the needle used, the amount of fluid withdrawn, and multiple punctures are factors that influence the development of headache. | | | The frequency and severity of headaches following lumbar puncture may be reduced by using a fine gauge needle, having the patient lie prone for 4 hours after lumbar puncture, and maintaining bed rest for 24 hours after the procedure. | | | It is believed that the mechanism is the loss of the CSF position to the brain so that when a patient is upright there is probably dilatation and tension based on the brain’s anchoring structures, the pain-sensitive dural sinuses, resulting in pain. |
