— Explanation · 中文詳解 —
嗜鉻細胞瘤（Pheochromocytoma）是一種腎上腺髓質腫瘤，會陣發性或持續性過度分泌兒茶酚胺（Catecholamines，如腎上腺素與正腎上腺素）。觸診腹部會對腫瘤施加物理壓力，極易誘發兒茶酚胺大量釋放，導致嚴重的高血壓危象（Hypertensive crisis），甚至引發中風或心律不整，因此絕對禁忌。
Palpating the abdomen is contraindicated in clients with a suspected pheochromocytoma because physical pressure on the tumor can trigger a massive release of catecholamines. This sudden surge can precipitate a hypertensive crisis, potentially leading to stroke or severe arrhythmias, making non-invasive assessment methods essential.
