人力败血症的特点是密集和大规模的感染，没有在本地主机中设置的全身反应。目前，在十大死亡原因，在美国重症监护病房 1中，败血症的行列。在败血症，有可能重叠的两个既定的血流动力学阶段。初始阶段（高动力）被定义为大规模生产的炎性细胞因子和活性氧的巨噬细胞和中性粒细胞，影响血管通透性导致低血压，心功能，导致代谢的变化，最终导致组织坏死和器官功能衰竭。因此，最常见的原因的死亡率是急性肾损伤。第二阶段（hypodynamic）是一个消炎的过程，涉及改变单核细胞抗原提呈，减少了淋巴细胞增殖功能和细胞凋亡增加。这种状态称为免疫抑制或免疫抑制大幅增加nocosomial感染和最终死亡的风险。这些病理生理过程的机制没有得到很好的特点。因为败血症的两个阶段，可能会导致不可逆的和不可弥补的损害，它是必不可少的，以确定患者的免疫和生理状态。这是许多治疗药物失败的主要原因。同一药物在不同的败血症阶段，可能是治疗或其他有害或有没有效果 2,3。了解在各级败血症关键是有一个合适的和全面的动物模型，再现了疾病的临床过程。这一点很重要的特点败血症过程中发生的病理生理机制，控制潜在的治疗药物测试模型条件。 为了研究人类败血症研究者的病因有不同的动物模型。临床使用最广泛的的模型是盲肠结扎穿孔（CLP）。电模式，使粪便材料释放进入腹膜腔，产生一个加剧的多种微生物感染引起的免疫反应的盲肠穿孔。这种模式符合人类生存条件，是临床相关。在人类，小鼠进行液体复苏的中华第一（初）高动力的阶段，在时间的推移到第二次（晚）hypodynamic阶段。此外，细胞因子的配置文件是类似人类败血症看到那里是增加淋巴细胞凋亡（4,5检讨） 。由于涉及多个重叠的败血症机制，研究人员需要一个合适的脓毒症模型控制的严重性，以取得一致的和可重复性的结果。
