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坑的肿胀,发生在皮肤或粘膜下层。它通常影响面部、嘴唇、颈部和四肢,以及口腔、喉咙和肠道等部位。当它影响喉咙时就会变得危险,可能会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.
最近接触过敏原(例如花生)可能是荨麻疹的原因,但荨麻疹的大多数原因尚不清楚。
面部皮肤(通常是口腔周围)以及口腔和/或喉咙以及舌头的粘膜会在几分钟到几小时内肿胀。肿胀可能会发痒或疼痛。荨麻疹可能同时发生。
在严重的情况下,会出现气道喘鸣,伴有喘息或喘息的吸气呼吸音以及氧气水平下降。在这些情况下需要气管插管,以防止呼吸停止和死亡风险。
