Clinical Trial Summary

The purpose of this study is to evaluate the long term effects of the ganglion sphenopalatine block (GSP block) on postdural puncture headache.

Description:

Adult patients with postdural puncture headache was enrolled in main study (NCT03652714). In the main study the patients was randomised to receive a ganglion sphenopalatine block (GSP-block) with either local anesthetic (lidocaine + ropivacaine) or placebo (isotone NaCl).

Following inclusion in the main study all participants are sent a follow-up questionnaire.

Primary outcome is disability due to headache defined as moderate to severe disability measured with Migraine Disability Assessment Test (MIDAS) in the 3 months following initial block and average pain score in the 3 months following the initial block on a 0-10 pain intensity scale.

Secondary outcome is disability due to headache defined as moderate to severe disability measured with Migraine Disability Assessment Test (MIDAS) in the 3 previous months as well as average pain scores in the previous 3 months, days with headache and long and short term side effects of the block.
