Greater Occipital Nerve Block Value in Management of Postdural Puncture Headache

Plain-language summary
Neuraxial techniques are well tolerated and effective options for labor analgesia and anesthesia for caesarean section, and may protect high risk women against severe maternal morbidity. However, neuraxial techniques still have drawbacks especially postdural puncture headache (PDPH) and may be associated with chronic headache, back pain and postnatal depression. PDPH is a relatively common acute complication of neuraxial techniques that was traditionally considered benign and self-limiting, but it significantly impacts patients' general health and quality of life.
Greater Occipital Nerve (GON) originates from C2-3 segments and through its muscular relations it is divided as proximal and distal parts; the most proximal part lies between obliquus capitis inferior and semispinalis and then passes through the semispinalis to pierce the trapezius muscle. In distal region of trapezius fascia, the GON is crossed by the occipital artery and exits the trapezius fascia into the nuchal line about 5-cm lateral to midline. Functionally, GON provides motor supplies to the muscles while passing through it and its main sensory supply is in the occipital region.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients with postdural puncture headache;
* Patients partially improved on conservative treatment and required a definitive pain relieving management;
* Patients who were intolerant to conventional analgesics;
* Patients who did not receive or did not improve on conservative therapies.
Exclusion Criteria:
* Patients had postdural puncture headache who were improving on conservative treatment and refused further interventions;
* Patients who had headache secondary to local or systemic disease, cervical radiculopathy, manifest diabetes mellitus;
* Patients dependent on routine analgesia for other causes were excluded from the study;
* Patients refused to participate in the study or to sign the written consent;
* Patients missed during follow-up were not included in the study.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
