Sphenopalatine Ganglion Block for Postdural Puncture Headache in the Emergency Department

September 23, 2019 updated by: University of Arkansas

Sphenopalatine Ganglion Block for Treatment of Postdural Puncture Headache in the Emergency Department: A Prospective, Randomized, Double-Blind Placebo Controlled Study

This study evaluates sphenopalatine ganglion block (SPGB) for the treatment of postdural puncture headache (PDPH) in the emergency department (ED). Half of the patients will receive a true nerve block with lidocaine and bupivacaine. The other half will receive a placebo nerve block.

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

Postdural puncture headaches (PDPH) are a common consequence of diagnostic lumbar puncture. The gold standard treatment for a PDPH is currently an autologous epidural blood patch (AEBP), which involves placing a needle into the epidural space of the spine and then injecting 20 ml of the patients own blood through the needle and into the epidural space to form a clot over the tear in the tissue layer that causes the headache. This is an invasive procedure that carries risks of pain, bleeding, infection, and in rare cases, neurological complications. We want to test the efficacy of using a less invasive procedure, called a sphenopalatine ganglion block (SPGB), for treatment of PDPH. SPGB has been used for many years in the treatment of migraines and cluster headaches, and there are several case reports of its use to successfully treat PDPH as well. SPGB simply involves applying a local anesthetic to the mucosa in the back of each nostril to numb the nerves that cause the headache. We hope that the SPGB will reduce the number of PDPH patients that require an AEBP.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

ACTIVE_COMPARATOR: Sphenopalatine Ganglion Block
Subjects will be asked to blow out each nostril. They will then be laid supine with a small shoulder roll and intranasal phenylephrine 0.25% (RhinallⓇ) will be sprayed once into each nostril to preemptively minimize bleeding. Sphenopalatine ganglion block will be performed by inserting long cotton tipped applicators saturated in 2% viscous lidocaine into nostril until properly seated in the posterior nasopharynx. These will be left in place for 10 minutes and then 1 mililiter of 0.5% bupivacaine will be administered down the plastic hollow shaft of each applicator via an 18g angiocatheter. The applicators will remain in place for 10 more minutes and then be removed.

They will then be laid supine with a small shoulder roll and intranasal phenylephrine 0.25% (RhinallⓇ) will be sprayed once into each nostril to preemptively minimize bleeding. SPGB will be performed by inserting long cotton tipped applicators saturated in carboxymethylcellulose based lubricant (i.e. K-Y Jelly®) into nostril until properly seated in the posterior nasopharynx. These will be left in place for 10 minutes and then 1 mililiter of normal saline will be administered down the plastic hollow shaft of each applicator via an 18g angiocatheter. The applicators will remain in place for 10 more minutes and then be removed.
