大肠杆菌内毒素休克狗平均动脉压变化规律基本一致,心搏出量和体循环总外周阻力变化的差异较大,可将其大致区分为“低排-低阻”、“低排-高阻”和“高排-低阻”三种类型,且绝大多数动物以“低排-低阻”开始和告终。“高排-低阻”代偿最有效,“低排-高阻”次之,低排-低阻”最差,后者实际上是失代偿的表现。体液因子的变化提示,“低排-低阻”型动物胆碱能系统的活动占优势,“低排-高阻”型动物肾上腺素能系统的活动占优势,“高排-低阻”型动物两个系统的活动接近于相对平衡。
The changes of mean arterial pressure in endotoxin-induced Escherichia coli in dogs were basically the same, the differences of cardiac output and total peripheral resistance in systemic circulation were quite different, which could be roughly divided into “low-row-low-resistance”, “low-row- And ”high row - low resistance“ three types, and the vast majority of animals to ”low row - low resistance“ began and ended. ”High-row-low-resistance“ is the most effective compensation, ”low row - high resistance“ second, low row - low resistance ”worst, the latter is actually the performance of decompensation.Humoral fluid changes suggest that“ low The activities of cholinergic system of ”low-row and low-resistance“ type animals predominate, the activity of ”low-row-high-resistance“ type animals predominates, and the activities of ”high-row and low- Relatively balanced.
