休克指数在失血性休克中的监测意义

Value of Shock Index on the Survey in Hemorrhagic Shock

目的:探讨休克指数(SI)在家兔失血性休克监测中的重要意义。方法:以Wiggers改良法复制失血性休克家兔模型,并回输自身血液进行复苏,用生物学检测系统检测家兔心率(HR)、平均动脉压(MAP)、统计失血量(BV)、计算休克指数(SI)、记录造模前,造模后和复苏后的上述指标,当复苏后血压稳定终止试验。结果:心率(HR)、平均动脉压(MAP)、休克指数(SI)与失血量的相关性分别为0.792、0.835、0.951,P<0.05,有统计学意义。结论:休克指数与家兔失血性休克的失血量明显相关,可能更有助于家兔失血性休克状态的评价。

Objective：To assess the value of shock index（SI） on the survey in rabbits with hemorrhagic shock.Methods：The models of hemorrhagic shock in rabbits were produced by improved Wiggers method.The blood rabbits have lost will be feedback as a therapy.The mean arterial pressure（MAP）,heart rate（HR） were measured before bleeding and at different time points after hemorrhagic shock.The shock index and bleeding volume were calculated.Result：Statistically significant correlation were found between bleeding volume and HR,MAP,SI（r=0.792,0.835and 0.951 respectively）.Conclusions：SI seems to correlated better with bleeding volume than HR and MAP,it appears therefore to be a more reliable estimator of hemorrhagic shock.
