Angioedema is an area of swelling (edema) of the lower layer of skin and tissue just under the skin or mucous membranes. The swelling may occur in the face, tongue, larynx, abdomen, or arms and legs. Often it is associated with hives, which are swelling within the upper skin. Onset is typically over minutes to hours.
Angioedema 是指按压时不会留下凹陷的肿胀,发生在皮肤或黏膜下层。它通常影响面部、嘴唇、颈部和四肢,以及口腔、咽喉和肠道等部位。当它累及喉咙时会变得危险,可能导致危及生命的情况。 Angioedema is non-pitting edema that involves subcutaneous and/or submucosal layers of tissue that affects the face, lips, neck, and extremities, oral cavity, larynx, and/or gut. It becomes life-threatening when it involves the larynx.
近期接触过敏原(如花生)可能诱发荨麻疹,但大多数荨麻疹的原因仍不明。
面部皮肤(多为口周围)以及口腔、喉咙或舌头的黏膜可在数分钟至数小时内出现肿胀,伴随瘙痒或疼痛,且荨麻疹常同时出现。
严重时可能出现气道喘鸣、吸气性呼吸音以及血氧下降,此时需进行气管插管,以防止呼吸停止和降低死亡风险。
