Vagal hypotension can occur after percutaneous biopsy and be misdiagnosed as hypovolemia due to hemorrhage. Inappropriate exploratory surgery and death have resulted. Increased vagal tone or massive discharge is characterized by hypotension with bradycardia or lack of tachycardia and can occur after many stimuli including contrast medium injection, anxiety, and needle insertion. Vagal reactions can be mild and self-limited, but can also progress to cardiac arrest. Atropine 0.6 to 0.8 mg intramuscularly or intravenously in increments up to 3 mg has been recommended for prompt treatment. Volume expansion is adjunctive.
经皮活检后可发生迷走神经性低血压，可能因出血被误诊为低血容量。这已导致不适当的 exploratory surgery（此处原文有误，可能是“exploratory laparotomy”即剖腹探查术）及死亡。迷走神经张力增加或大量放电表现为低血压伴心动过缓或无心动过速，可在包括注射造影剂、焦虑和针刺在内的多种刺激后发生。迷走神经反应可能轻微且为自限性，但也可能进展为心脏骤停。推荐立即肌内或静脉注射 0.6 至 0.8 毫克阿托品，可增量至 3 毫克。扩容为辅助治疗。
