Ultrasound-Guided Peripheral Nerve Block as the Sole Anesthetic for Above-Knee Amputation in a Patient With Severe Cardiopulmonary Comorbidities.
Article in Cureus, 2026. 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
Above-knee amputation (AKA) carries substantial perioperative risk in patients with advanced cardiopulmonary disease for whom general and neuraxial anesthesia are poorly tolerated. Data supporting peripheral nerve blocks (PNBs) as the primary intraoperative anesthetic remain limited. We present a 79-year-old male with extensive cardiopulmonary and metabolic comorbidities who underwent left AKA for chronic limb-threatening ischemia. Ultrasound-guided sciatic, femoral, obturator, and lateral femoral cutaneous nerve blocks using ropivacaine were performed as the sole anesthetic with intravenous midazolam, achieving complete anesthesia without hemodynamic compromise. The Visual Analog Scale score was 0 postoperatively. The technique was reproduced successfully for contralateral amputation, reinforcing the role of PNBs as a primary anesthetic strategy in high-risk patients.
