【摘要】 目的探讨猴脑选择性超深低温断血流复苏的可行性。方法4至10岁健康恒河猴10只,动物随机分为3组:4血管(双侧颈总动脉及椎动脉)阻断冷灌注组4只,2血管(双侧颈总动脉)阻断冷灌注组4只,等温灌注组2只。手术前后行头颅MRI检查,手术中监测生命体征及血流动力学指标变化,术后行神经功能缺失评分。结果在10只实验猴中,2血管阻断冷灌注组4只恒河猴术中、术后血流动力学稳定,灌注60min后安全复苏并长期存活,术后头颅MRI检查未见异常,术后神经功能评分无异常;等温灌注组2只恒河猴及4血管阻断冷灌注组4只恒河猴于灌注60min后均未能安全复苏,全部死亡。结论阻断双侧颈总动脉行猴脑选择性超深低温60min后可安全复苏。更多还原

【Abstract】 Objective To study the feasibility of resuscitation after selective cerebral ultra-deep hypothermia and blood flow occlusion. Methods Ten 4-10 year-old maca mulattas were divided into 3 groups: four-vessel occlusion group, two-vessel occlusion group and identical temperature perfusion group. MRI were examinated before and after operation, the vital signs and the hemodynamical parameters were observed during the experiment, neurological deficient evaluation was performed after operation. Results In all of the ten monkeys, the hemodynamical parameters of two-vessel occulation were steady during the operation, and all of them lived after filling 60 minutes. MRI were normal after operation, and the function of neurological deficient scale was normal.The others of identical temperature perfusion group and four-vessel occlusion group were not resuscitation after filling 60 minutes and died. Conclusion Monkey could resuscitate from selective cerebral ultra-deep hypothermia and blood flow occlusion of bilateral common carotid artery in 60 minutes.更多还原
