Sphenopalatine Ganglion Block Versus Occiptal Nerve Block in Treatment of Post Dural Puncture Headache (PDPH)

August 4, 2020 updated by: Hala Saad Abdel-Ghaffar, Assiut University

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Numeric rating pain score
Time Frame: from intervention up to 24 hours
pain score

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
