Sphenopalatine Ganglion Block for Postdural Puncture Headache in the Obstetric Population: A Narrative Review.
Review in Journal of pain research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Postdural puncture headache (PDPH) frequently complicates neuraxial anesthesia, delaying patient recovery and reducing quality of life after surgery. Epidural blood patch (EBP), the conventional standard of care, is effective but not without risks. Therefore, safer, less invasive alternatives are of increasing interest. The sphenopalatine ganglion block (SPGB) is a minimally invasive regional analgesic technique that has drawn attention in recent years for managing PDPH, largely because it is non‑opioid and generally well tolerated. In this narrative review, we summarize current knowledge on the anatomical basis, proposed mechanisms, procedural techniques, and clinical evidence (mostly from case reports and case series) for SPGB in the obstetric population, and we discuss key controversies that remain unresolved.
