Assessing patient knowledge and concerns about peripheral nerve blocks: Implications for preoperative education.
Article in Saudi journal of anaesthesia. 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
Background: Peripheral nerve blocks offer numerous advantages, including reduced postoperative pain, decreased opioid use, and faster recovery. Despite their benefits, patients' understanding of peripheral nerve blocks remains poorly characterized. This survey study aimed to assess patient knowledge of peripheral nerve blocks among individuals undergoing outpatient orthopedic surgery. Methods: Adult patients scheduled for outpatient orthopedic surgery and awaiting consent for peripheral nerve blocks between February 18, 2025 and July 3, 2025 at a single academic institution were eligible for inclusion. Pediatric and non-English-speaking patients were excluded. After providing written consent, participants completed a one-time written survey in the preoperative area on the day of surgery. The survey included 10 "true/false" statements assessing knowledge of peripheral nerve block mechanisms, applications, outcomes, and comparisons with general anesthesia. Participants also ranked concerns regarding potential complications, including neurological, vascular, and infectious ones, allergic/autoimmune reactions to anesthetic, and pain during the procedure. Results: Most patients reported limited prior understanding, with only 4.0% identifying as "very knowledgeable." Only 27.7% reported receiving prior explanations about peripheral nerve blocks from a non-anesthesiologist physician. Neurological and infectious complications were ranked as the most concerning. Conclusion: This study identified significant knowledge gaps, particularly regarding continuous peripheral nerve blocks and distinctions between peripheral nerve blocks and general anesthesia. These findings highlight the need for targeted preoperative educational initiatives to support informed decision-making and improve patient-centered outcomes.
