严重创伤病人常有低体温,但这种低温是机体的一种不利的生理反应抑或保护性的生理反应,还不清楚。缺血性损伤后液体复苏产生的主要后果之一即形成具有缺血-再灌注损伤模型特征的水肿。本文旨在研究区域低温对猫缺血-再灌注损伤的肠模型毛细血管通透性改变的影响。实验采用成年猫,麻醉下剖腹将一段长15～20cm自体灌注的回肠分离,并分别在动脉、静脉和淋巴管内插管以测定淋巴流量(Q_1)、淋巴(C_1)和血浆(C_p)蛋白质浓
Severe trauma patients often have hypothermia, but the cold is an adverse physiological reaction or protective physiological response is unclear. One of the major consequences of fluid resuscitation after ischemic injury is the formation of an edema that is characteristic of an ischemia-reperfusion injury model. The aim of this study was to investigate the effect of regional hypothermia on changes of capillary permeability in intestinal models of ischemia-reperfusion injury in cats. In this study, adult cats were anesthetized and a section of autologous ileum of 15-20 cm in length was dissected under anesthesia. Intrathecal arterial, venous and lymphatic vessels were inserted to determine the contents of lymphatic flow (Q_1), lymphocytes (C_1) and plasma protein (C_p)
