低温液体灌注产生亚低温的进展

低温对脑损伤的保护作用已被众多动物实验所证实,在临床方面,尤其是发现轻度和中度低温的保护作用之后,应用逐渐增多.近年来,亚低温被用于治疗新生儿缺氧性脑病、心肺复苏后脑保护、脑外伤及脑卒中等领域.目前临床及实验中所应用的低温方式主要为全身亚低温,如降温毯、冰袋等,这些方式降温效率低,不易迅速实现亚低温,而且全身低温可伴有多种并发症,如心律紊乱、凝血功能障碍等.低温液体或自体血液灌注是目前最有效的降温方式,而且局部动脉内灌注低温液体更可以快速实现局部亚低温.介入技术的进步使得快速局部动脉内低温液体灌注成为可能.我们详细回顾相关动物实验及临床应用文献,介绍低温液体灌注产生亚低温的研究进展.

Development of regional cerebral sub-hypothermia with perfusion of hypothermic liquids

The neuroprotection of induced hypothermia has been investigated intensively and confirmed in animal models and it has been used clinically in many fields since the finding of sub-hypothermia can also reduce cerebral injury. However the use of hypothermia in clinics is limited by the simultaneously induced systemic complications. Recently the sub-hypothermia induced by hypothermic regional arterial perfusion is proved to be the most effective method to reach the goal, including hypothermic normal saline with no influences on whole body temperature, cardiac rhythm and blood coagulation. According to the well development, fruitful achievement in the present status of this field, we are surely to have the inspiration for the further investigation and development of regional cerebral sub-hypothermia with perfusion of hypothermic liquids.
