【答】猝死型胰腺炎发生猝死的机理目前还不十分清楚,可能与以下因素有关. 1.休克:导致休克的原因:(1)出血坏死的胰腺,能释放使小血管扩张和毛细血管通透性增加的物质——缓激肽、组织胺及其他血管活性物质.缓激肽是一种调节小血管口径的激素,可使小血管扩张,血压下降,毛细血管通透性增加,体液渗出.组织胺和其他血管活性物质也具有上述作用.由于以上原因,大量的体液通过毛细血管壁渗入腹腔,
[A] Sudden death of sudden death The mechanism of sudden death is not yet very clear, may be related to the following factors: 1. Shock: Causes of shock: (1) hemorrhagic necrosis of the pancreas, can release small blood vessels and capillary expansion Increased permeability of substances - bradykinin, histamine and other vasoactive substances. Bradykinin is a regulator of small blood vessels caliber hormones, can make small blood vessels dilate, decreased blood pressure, increased capillary permeability, body fluid seepage Histamine and other vasoactive substances also have the above effects.For these reasons, a large number of body fluids through the capillary wall infiltration into the abdominal cavity,
