Table 2. Number of Patients with a Postdural Puncture Headache and Number of Patients Requiring an Epidural Blood Patch

There were a total of 12 headaches. Both needles used: the patient was initially randomized to the Sprotte group. No cerebrospinal fluid (CSF) was obtained from that needle and then a Gertie Marx needle was subsequently used. At no time was the Gertie Marx needle used first without obtaining CSF.

*P < 0.05 versus  both the Sprotte and Gertie Marx needles used alone.
