Abstract: | In a prospective study lumbar iohexol myelography was performed in 107 consecutive patients, randomised for lumbar puncture with a Quincke or Whitacre spinal needle. All patients answered a questionnaire about possible side effects. Data from 100 patients (58 men, 42 women) were evaluated. In the Quincke group (n = 53), 23 (43 %) reported no side effects. In the 30 patients who reported various side effects, post-dural puncture headache (PDPH) occurred in 22 (42 %), of whom 9 had mild, 6 moderate and 7 (13 %) severe cephalalgia, 18 (34 %) reported increased low back pain/sciatica, 5 nausea and 7 dizziness. In the Whitacre group (n = 47), 33 (70 %) had no side effects. PDPH was reported by 9 patients (19 %), of whom 2 had mild, 6 moderate and only 1 (2 %) severe cephalalgia, 4 (9 %) reported increased low back pain/sciatica, 5 nausea and 4 dizziness. The conclusion drawn from this study is that lumbar myelography performed with the Whitacre spinal needle reduces postspinal side effects. |
