How to minimize pain with local anesthesia and improve patient experiences: a review.
Review in Anais brasileiros de dermatologia. 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
backgroundLocal anesthesia is essential in common procedures in dermatology, but injection and infiltration of anesthetic often cause significant pain, reducing patient comfort and satisfaction.
objectiveTo review evidence-based techniques to reduce pain associated with local anesthetic injection and infiltration. METHODS AND MATERIALS: A narrative review of the literature was performed, and techniques were summarized for clinicians to reference.
resultsTechnical methods to reduce pain include using smaller-gauge needles (30-33G), smaller syringes (1‒3 mL), buffering lidocaine with sodium bicarbonate, inserting the needle at 90 degrees, slow infusion, subcutaneous delivery, and pore-guided injection. Adjuncts such as warming anesthetic, vibration, ice, music, and verbal distraction ("talkesthesia") also reduce patient perception of pain. STUDY LIMITATIONS: Limitations include heterogeneity in study designs, outcomes measures, and clinical contexts across the included literature, precluding quantitative synthesis or direct comparison of individual techniques. Additionally, several recommendations are based on expert opinion or limited evidence.
conclusionA multimodal approach using both technical refinements and adjunctive measures can make local anesthetic administration less painful. Dermatologists may routinely implement these strategies to improve patient experience and satisfaction.
