Sphenopalatine Ganglion Block for Post-Dural Puncture Headache

Sphenopalatine Ganglion Block for Treatment of Postdural Puncture Headache: A Prospective Randomized Double Blind Placebo Controlled Study

The investigators are attempting to determine a less invasive method of treatment for postdural puncture headaches that can occur after regional anesthesia. The investigators will be evaluating the relief of headache with those subjects receiving treatment with a sphenopalatine ganglion block with bupivacaine versus placebo, evaluating the incidence of epidural blood patch, pain score of headache at 1 hour, then 24, 48, and 72 hours lower with post study treatment versus placebo, and potential side effects of those patients receiving study therapy as well as epidural blood patch.

Inclusion Criteria:

• American Society of Anesthesiologists assigned class I-III
• age >/= 18 years
• experiencing a postdural puncture headache within 7 days of neuraxial analgesia rated >3/10 pain score

Exclusion Criteria:

• allergy to study medications <18 years of age pain score on presentation </=3/10 for headache
