摘要:

背景:研究表明异羟戊酸对于失血性休克后动物重要脏器有一定的保护作用,7.5%高渗盐对于失血性休克血流动力学的稳定作用显著。
目的:观察异羟戊酸复合7.5%高渗盐对失血性休克大鼠血流动力学的影响。
方法:将50只大鼠随机等分为5组:假手术组、休克不复苏组、异羟戊酸组、7.5%高渗盐组和7.5%高渗盐复合异羟戊酸组,除假手术组外其他4组建立失血性休克模型。假手术组麻醉置管后不予失血;休克不复苏组失血不复苏,观察60 min后处死;其他3组在失血60 min后分别在5 min和20 min内经静脉给予异羟戊酸、7.5%高渗盐溶液、异羟戊酸溶于7.5%高渗盐干预。各组经股动脉和右颈总动脉置管实时监测心率、平均动脉压和右室收缩压变化。
结果与结论:采取一定的复苏措施3 h后,与异羟戊酸组和7.5%高渗盐组相比,7.5%高渗盐复合异羟戊酸组心率最高(P < 0.05),复苏后不仅平均动脉压和右室收缩压上升平稳,作用时间持久且波动较小(P < 0.05)。实验结果证实,7.5%高渗盐复合异羟戊酸干预对于失血性休克后大鼠复苏效果优于传统的高渗盐溶液复苏以及单纯的药物复苏。

Abstract:

BACKGROUND: Studies have shown that suberoylanilide hydroxamic acid (SAHA) has protective effects in some vital organs in animals after hemorrhagic shock, and 7.5% hypertonic saline (HS) exerts significant effects on stabilizing the hemodynamics of hemorrhagic shock animals.
OBJECTIVE: To evaluate the effect of SAHA combined with HS on the hemodynamics of hemorrhagic shock rats.
METHODS: Fifty rats were randomly and equally divided into five groups: sham, shock non-resuscitation, SAHA, 7.5% HS, and 7.5% HS + SAHA. Each group contained 10 rats. Except the sham group, rats in the remaining four groups were applied to establish hemorrhagic shock models. In the sham group, rats were given anesthesia catheter, not bleeding; in the shock non-resuscitation group, the bleeding was found, but rats were not resuscitated and were killed after 60 minutes of observations; in the other three groups, rats were respectively resuscitated at 60 minutes after bleeding, through intravenous administration of SAHA within 5 minutes, 7.5% HS and SAHA + 7.5% HS within 20 minutes. Heart rate, mean arterial pressure and left ventricular systolic pressure were monitored through the femoral artery and the right common carotid artery catheter in each group.
RESULTS AND CONCLUSION: At 3 hours after resuscitation, the heart rate was the highest in the 7.5% HS + SAHA group, compared with the SAHA and 7.5% HS groups (P < 0.05). After resuscitation, the mean arterial pressure and left ventricular systolic pressure were increased, with long-lasting effect and less fluctuation (P
0.05). Experimental results show that 7.5% HS combined with SAHA has a superiority than traditional HS and simple drugs for resuscitation after hemorrhagic shock.
