Ultrasound-Guided Peripheral Nerve Block for Emergency Below-Knee Amputation in a High-Risk Patient With Coagulopathy: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Emergency below-knee amputation (BKA) in patients with significant comorbidities and coagulopathy presents formidable anesthetic challenges, as a central neuraxial blockade and general anesthesia are frequently contraindicated. We report the case of a 57-year-old female patient with uncontrolled diabetes mellitus, chronic kidney disease, coronary artery disease, and an elevated international normalized ratio (INR) of 1.6, necessitating urgent BKA for a septic diabetic foot ulcer. Ultrasound-guided peripheral nerve blocks (PNBs, popliteal sciatic and femoral) have been successfully employed to achieve effective intraoperative anesthesia and postoperative analgesia without bleeding complications or hemodynamic instability. This case underscores the safety and efficacy of ultrasound-guided PNBs as the preferred anesthetic strategy in high-risk patients with coagulopathy, offering a safer alternative to conventional methods and minimizing perioperative morbidity.
