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.


Clinical Trial 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. ;
