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 是指按壓時不會留下凹陷的腫脹,發生於皮膚或黏膜的下層。它常見於臉部、嘴唇、頸部和四肢,也可能累及口腔、喉嚨及腸道等部位。若累及喉嚨,則可能危及生命,需立即就醫。 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.
最近接觸過敏原(例如花生)可能是蕁麻疹的原因,但大多數蕁麻疹的成因尚不明確。
臉部皮膚(常見於口腔周圍)以及口腔、喉嚨或舌頭的黏膜,會在數分鐘至數小時內腫脹。腫脹可能伴隨癢感或疼痛,且蕁麻疹可能同時出現。
在嚴重情況下,可能出現氣道喘鳴、呼吸困難或吸氣時的喘息音,並伴隨血氧濃度下降。此時需要氣管插管,以防止呼吸停止及降低死亡風險。
