Association Between Local Anesthetic Dosing, Postoperative Opioid Requirement, and Pain Scores After Lumpectomy and Sentinel Lymph Node Biopsy with Multimodal Analgesia.
Article in Annals of surgical oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundMultimodal analgesia (MMA) during breast surgery reduces postoperative pain and opioid requirements, but the relative contribution of local anesthetic dosing as a component of MMA is not well defined among patients undergoing lumpectomy and sentinel lymph node biopsy (SLNB). PATIENTS AND
methodsWe identified consecutive patients who underwent lumpectomy and SLNB with MMA from 1/2019 to 4/2020. Univariable and multivariable linear and logistic regression were used to examine associations between local anesthetics, opioid requirements in the post-anesthesia care unit (PACU), and pain scores in the PACU and on postoperative day (POD) 1.
resultsIn total, 1603 patients [median tumor size, 14 mm (interquartile range 8-20 mm)] were included. The median PACU opioid requirement was 0 morphine milligram equivalents (interquartile range 0-5). PACU maximum pain was none or mild in 58% of patients and moderate to severe in 42%; among 420 survey respondents, 56% reported no or mild pain and 44% reported moderate to severe pain on POD 1. On multivariable analysis that adjusted for routine components of MMA, increasing doses of 0.5% bupivacaine were associated with reduced PACU opioid requirements (β -0.04, 95% confidence interval -0.07 to -0.01, p = 0.011) and lower odds of moderate to severe pain (odds ratio 0.98, 95% confidence interval 0.97-0.99, p < 0.001). Local anesthetics were not associated with pain scores on POD 1.
conclusionsHigher amounts of local anesthetics reduce acute postoperative pain and opioid requirement after lumpectomy and SLNB. Maximizing dosing within weight-based limits is a low-risk, cost-effective pain control strategy that can be used in diverse practice settings.
