Trial summary

Postdural puncture headache (PDPH) is a common complication associated with neuraxial anesthesia and diagnostic lumbar puncture (LP). PDPH is defined as a bilateral headache that develops within 7 days and disappears within 14 days after the dural puncture with a distinct postural quality. Read more about this study

About this study

Official title: Sphenopalatine Ganglion Block Versus Occiptal Nerve Block in Treatment of Postduarl Puncture Headache

Postdural puncture headache (PDPH) is a common complication associated with neuraxial anesthesia and diagnostic lumbar puncture (LP). PDPH is defined as a bilateral headache that develops within 7 days and disappears within 14 days after the dural puncture with a distinct postural quality. PDPH causes significant short-term disability, prevents ambulation and care of the newborn (in obstetrics), and results in a prolonged hospital stay.

Read the detailed description

The sphenopalatine ganglion (SPG) is an extra-cranial neural structure located in the pterygopalatine fossa that has both sympathetic and parasympathetic components as well as somatic sensory roots. The trans-nasal approach is a low risk, noninvasive technique that is easily performed and could potentially be beneficial in the treatment of PDPH through blocking the parasympathetic flow to the cerebral vasculature through the sphenopalatine ganglion which will allow the cerebral vessels to return to normal diameter and thus relieve the headache.

The greater occipital nerve contains sensory fibers from C2 and C3 segments of medulla spinals. It arises from the dorsal ramus of C2 segment, contains a thin branch from C3 segment, and innerves the medial aspect of posterior scalp up to the anterior aspect of vertex. Greater occipital nerve block (GONB) inhibits the pain sensation of this region.

There is some evidence to suggest the effectiveness of GONB in the management of PDPH. Nowadays, guidelines for the management of PDPH were modified and included GONB as a part of standard management of PDPH.

  • Dexamethasone possess potent antiinflammatory and immunosuppressive actions by inhibiting cytokine-mediated pathways.
  • Many providers believe that the local anesthetic produces the rapid onset of headache relief, like an abortive agent, and that the locally acting steroid produces the preventive like action of up to 6 weeks.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sphenopalatine blockProcedure or surgery

    Also called SPGB

    patients will receive bilateral sphenopalatine ganglion block using 3ml mixture of 2ml 2% lidocaine plus 1ml dexamethasone 4mg (on each nostril).

  • Greater occipital nerve blockProcedure or surgery

    Also called GONB

    patients will receive bilateral greater occipital nerve block using a mixture of 3ml of 2ml 2% lidocaine plus 1ml dexamethasone 4mg (on each side of the occipital region).

Questions about this trial

What is this clinical trial studying?

A study testing Sphenopalatine block and Greater occipital nerve block in people with Headache, run by Assiut University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Numeric rating pain score (time frame: from intervention up to 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Aug 2020.
