Effects of ultrasound-guided nerve block combined with PCIA analgesia on postoperative pain, inflammatory response, hospital stay, and adverse reactions in breast cancer 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
Background: This study aimed to evaluate the effects of ultrasound-guided combined nerve block with patient-controlled intravenous analgesia (PCIA) on postoperative pain, inflammatory response, hospital stay, and adverse reactions in breast cancer surgery. Methodology: A total of 100 patients undergoing radical mastectomy for breast cancer were randomly assigned to two groups. The combined group received ultrasound-guided thoracic nerve block with PCIA, while the PCIA group received PCIA alone. Visual Analogue Scale (VAS) scores for pain were assessed postoperatively at intervals, and levels of inflammatory response markers (IL-6, TNF-α, hs-CRP) were compared before and after surgery. Analgesic efficacy, sufentanil dosage, hospitalization conditions, and safety profiles were recorded. Results: The combined group exhibited significantly lower VAS scores for resting and active pain at various postoperative time points compared to the PCIA group. Inflammatory markers at 48h post-surgery were notably lower in the combined group. Sufentanil consumption, analgesia pump use, rescue analgesia rate, and duration of effective pain relief were all improved in the combined group (P<0.05). Conclusions: Ultrasound-guided nerve block combined with PCIA effectively reduced analgesia pump usage, alleviated postoperative pain, and suppressed inflammatory marker expression. However, it showed minimal impact on hospital stay and adverse reactions, making it a promising strategy for postoperative pain management in breast cancer surgery.
