Effects of Intercostal Nerve Cryoablation on Pain Control and Pulmonary Recovery after Open Aortic Repair via Left Thoracotomy.

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
purposeThe aim of this study was to evaluate the impact of intercostal nerve cryoablation on postoperative pain, opioid usage, and lung expansion after open aortic repair via left thoracotomy.
methodsThis retrospective study included 62 patients who underwent aortic repair via left thoracotomy between 2017 and 2023. Patients were divided into cryoablation (n = 32) and non-cryoablation (n = 30) groups. Pain was assessed using the Numerical Rating Scale (NRS), and lung volume was measured using computed tomography 1 week postoperatively.
resultsThe cryoablation group showed significantly lower mean NRS scores (1.7 vs. 2.4, p <0.01) and lower opioid consumption (6.2% vs. 56.6%, p <0.01). The left lung volume ratio was significantly higher in the cryoablation group (72.3% vs. 62.4%, p = 0.05).
conclusionsIntercostal nerve cryoablation effectively reduces postoperative pain and opioid consumption and enhances pulmonary expansion after left thoracotomy. This technique may offer a favorable analgesic option in thoracic aortic surgery.
