A Rare Case Report of Contrast Media-induced Sympathetic Crashing Acute Pulmonary Edema.

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
introductionSympathetic crashing acute pulmonary edema (SCAPE), also known as flash pulmonary edema or hypertensive acute heart failure, is a critical condition characterized by a rapid escalation of sympathetic outflow, excessive afterload, and worsening heart failure. Although rare, contrast media-induced pulmonary edema is a severe adverse reaction, occurring in 0.001-0.008% of patients receiving intravenous contrast and accounting for 10-20% of lethal contrast reactions. CASE REPORT: A 70-year-old male developed acute respiratory distress shortly after undergoing an outpatient, contrast-enhanced computed tomography. Despite treatment for suspected anaphylaxis, the patient's condition continued to deteriorate until a diagnosis of SCAPE was ultimately recognized. Treatment with high-dose nitroglycerin, non-invasive positive pressure ventilation (NIPPV), and eventual intubation resulted in the patient's full recovery.
conclusionThis report highlights the importance of recognizing SCAPE in patients presenting with sudden dyspnea after contrast administration and emphasizes the need for early intervention with NIPPV and vasodilators to reduce morbidity and mortality.
