Abstract:
Objective:The objective of this study is to detect the effects of normothermic,mild hypothermic,hypothermic cardiopulmonary bypass(CPB) on somatosensory,cortical evoked potential(SCEP) and super microstructure of cortex in rabbits. Methods:Thirty new zealand white rabbits,randomly allocated into three groups;group A:normothermia CPB(36℃～37℃); group B:mild hypothermia CPB (32℃～34℃);group C:hypothermia CPB (26℃～28℃);Made the open-heart CPB model, maintaining HCT 20%～25%,the duration of CPB is 2 hours;Stimulating from ischiadic nerve,recording SSEP by the time of the end of CPB,The animals were then killed and the cortex were removed for electro microscopic examination.Results:The latency of group C is longer than group B,the latency of group B is longer than the group A,compare between each group (P
