Retrospective evaluation of the effects of traditional interscalene block alone versus combined with superior truncus block-associated diaphragm paralysis during arthroscopic shoulder surgery.

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
objectivesThe aim of this study was to investigate the effects of traditional interscalene block (ISB) alone and ISB combined with superior truncus block (STB)-associated diaphragm paralysis evaluated by ultrasound, duration of analgesia, and rate of complication in patients undergoing arthroscopic shoulder surgery. PATIENTS AND
methodsBetween January 2020 and December 2022, a total of 285 patients (158 males, 127 females; mean age: 48.0±15.1 years; range, 18 to 80 years) who underwent arthroscopic shoulder surgery under ISB, either alone or combined with STB, were retrospectively analyzed. The patients were operated under ISB alone using 30 mL 0.5% bupivacaine (n=140) or ISB using 10 mL (n=67) or 5 mL 0.5% bupivacaine (n=78) combined with STB using 20 mL 0.5% bupivacaine. Ultrasound reports of all patients' diaphragm function were also retrieved. Duration of analgesia, need for additional analgesics, and the type of analgesic drugs, and evaluations of patient and surgeon satisfactions were evaluated. Degree of diaphragm paralysis considered as complete (≥75%), partial (25.1 to 74.9%) and no paralysis (≤25%) were evaluated for comparison between the block types.
resultsThe patients underwent operation due to rotator cuff rupture (n=218) or Bankart (n=67). Duration of analgesia, need for additional analgesia, and the type of analgesic drugs used were comparable between the block types. The most common complication was Horner syndrome (n=96, 33.68%) which was significantly lower in ISB (5 mL) +STB (20 mL) than the others (17.9% vs. 41.4% and 37.3%, p=0.002). The ISB (5 mL bupivacaine 0.5%) + STB (20 mL bupivacaine 0.5%) resulted in less complete diaphragm paralysis with adequate surgical anesthesia not requiring general anesthesia.
conclusionThe ISB using 5 mL of 0.5% bupivacaine + STB instead of traditional ISB alone can be preferred due to the low rate of complete hemi-diaphragm paralysis with adequate surgical anesthesia/analgesia and high patient and surgeon satisfaction.
