Regional Blocks Benefit Patients Undergoing Bilateral Mastectomy with Immediate Implant-Based Reconstruction, Even After Discharge.
Article in Annals of surgical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundThere is limited evidence that regional anesthesia reduces pain in patients undergoing mastectomy with immediate implant-based reconstruction. We sought to determine whether regional blocks reduce opioid consumption and improve post-discharge patient-reported pain in this population.
methodsWe retrospectively reviewed patients who underwent bilateral mastectomy with immediate implant-based reconstruction with and without a regional block. We tested for differences in opioid consumption by block receipt using multivariable ordinal regression, and also assessed routinely collected patient-reported outcomes (PROs) for 10 days postoperatively and tested the association between block receipt and moderate or greater pain.
resultsOf 754 patients, 89% received a block. Non-block patients had an increase in the odds of requiring a higher quartile of postoperative opioids. Among block patients, the estimated probability of being in the lowest quartile of opioids required was 25%, compared with 15% for non-block patients. Odds of patient-reported moderate or greater pain after discharge was 0.54 times lower in block patients than non-block patients (p = 0.025). Block patients had a 49% risk of moderate or greater pain compared with 64% in non-block patients on postoperative day 5. There was no indication of any reason for these differences other than a causal effect of the block.
conclusionReceipt of a regional block resulted in reduced opioid use and lower risk of self-reported moderate and higher pain after discharge in bilateral mastectomy with immediate implant-based reconstruction patients. Our use of PROs suggests that the analgesic effects of blocks persist after discharge, beyond the expected duration of a 'single shot' block.
