皮下气肿 Subcutaneous emphysema

(重定向自Tissue emphysema)
Bubbles of air in the subcutaneous tissue (arrow) feel like mobile nodules that move around easilyA chest X-ray of a right sided pulmonary contusion associated with flail chest and subcutaneous emphysemaSubcutaneous air (arrows) can be seen as black areas on this pelvic CT scan.

皮下气肿英语:Subcutaneous emphysema),亦被称为组织气肿,是指因空气或气体积存于皮下组织而形成的气肿。皮下气肿中的皮下是指位于皮肤表面下的组织,而气肿则是指积存在皮下组织的气体。皮下气肿可以被简称为SCESE。由于人体内的空气一般来自于胸腔,所以皮下气肿通常在胸腔附近的部位出现,如胸部,颈部或面部。这些空气通常沿着筋膜进入到其他组织。皮下气肿摸上去的质感像纸巾或米饼,按压的时候同时会发出些微劈啪的声音。这种声音在医学上被统称为皮下捻发音

医学界对皮下气肿的成因有不同的看法。第一个就皮下气肿的成因作出假设的人是何内·雷纳克,他在1819年的报告中指出,皮下气肿主要由皮肤创伤所做成。其后,路易·哈曼博士(Dr. Louis Hamman)于1939年指出,皮下气肿亦会在产后妇女身上出现。因此,皮下气肿亦被称为哈曼综合症。此外,L.麦克林(L. Macklin)、M.T.麦克林(M.T. Macklin)和C.C.麦克林(C.C. Macklin)于1939至1944年间,分别就皮下气肿的病理学成因作进一步的研究及补充,因此皮下气肿同时亦可被称为麦克林综合症

Subcutaneous emphysema 皮下气肿

(重定向自Tissue emphysema)
Bubbles of air in the subcutaneous tissue (arrow) feel like mobile nodules that move around easilyA chest X-ray of a right sided pulmonary contusion associated with flail chest and subcutaneous emphysemaSubcutaneous air (arrows) can be seen as black areas on this pelvic CT scan.

Subcutaneous emphysema is when gas or air is in the layer under the skin. Subcutaneous refers to the tissue beneath the skin, and emphysema refers to trapped air. It is sometimes abbreviated SCE or SE and also called tissue emphysema, or Sub Q air. Since the air generally comes from the chest cavity, subcutaneous emphysema usually occurs on the chest, neck and face, where it is able to travel from the chest cavity along the fascia. Subcutaneous emphysema has a characteristic crackling feel to the touch, a sensation that has been described as similar to touching Rice Krispies; this sensation of air under the skin is known as subcutaneous crepitation.
