摘要(Abstract):
目的探讨亚低温对急性脑梗死(ACI)并发脑心综合征(CCS)大鼠血清皮质酮(CORT)变化的影响及意义。方法将实验大鼠随机分为亚低温组、常温组及假手术组,亚低温组及常温组采用线栓法栓塞大鼠右侧大脑中动脉,术后连续监测标准Ⅱ导联心电图2h,统计各组脑心综合征的发病率,检测术后2h、24h、48h血清皮质酮的水平。结果亚低温组较常温组脑心综合征发病率低(P<0.05);常温组及亚低温组各时间点皮质酮水平均较假手术组增高,差异有统计学意义(P<0.05),常温组各时间点皮质酮水平均较亚低温组高,但只在2h点差别有统计学意义(P<0.05)。结论亚低温可能通过稳定应激激素的水平降低急性脑梗死大鼠并发脑心综合征的发病率。
