Comparison of PECS I Block and Local Anesthetic Infiltration for Pain Management in Breast Augmentation: A Prospective, Split-Body Study.
Article in Aesthetic plastic surgery, 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
backgroundWhile various analgesic methods have been proposed in breast augmentation, limited data exist comparing their efficacy in a controlled setting. This prospective, split-body study aimed to compare the effectiveness of preoperative PECS I block and intraoperative direct local anesthetic infiltration for postoperative pain control following breast augmentation.
methodsTwenty female patients (ASA I-II, aged 18-59) undergoing bilateral breast augmentation with identical implants via dual-plane or submuscular approaches were included. Each patient received a PECS I block on the right breast (10 mL of 0.5% bupivacaine) performed preoperatively by the same anesthesiologist. The left breast received an identical dose via direct local anesthetic infiltration administered by the same plastic surgeon prior to muscle transection. Postoperative pain was evaluated using the Numeric Rating Scale (NRS) at 30 min intervals for the first 2 h, every 2 h between 2 and 6 h, at 24 h, on postoperative day 5, and at 3 months.
resultsPain scores were significantly lower on the PECS I block side compared to the local infiltration side during the early postoperative period (30 min to 6 h) (p < 0.05). No significant difference was observed at 24 h, day 5, or 3 months. The mean tramadol requirement in the first 6 h was 72.0 ± 10.05 mg, with a total of 171.0 ± 21.98 mg at 24 h.
conclusionsIn this split-body study, PECS I block provided superior pain control during the early postoperative period (first 6 h) compared to direct local infiltration.
