摘要 目的 研究液体复苏不同水平对感染性休克犬多内脏血流量和动脉血乳酸的影响。方法  7只感染性休克犬 ,生理盐水复苏至不同肺动脉嵌顿压 (PAOP)水平 ,用血流量仪测定休克前后、不同复苏水平后肝动脉、门静脉和肠系膜上动脉血流量 ,分析动脉血乳酸。结果 犬感染性休克后肝动脉、门静脉和肠系膜上动脉血流量 (肠道血流 )分别减少 49 8%、46 1 %和 61 8% (P <0 0 0 1 ) ,肝灌注减少 47 95 % (P <0 0 0 1 ) ;复苏至PAOP为 (8 7± 0 9)mmHg时 ,肝动脉、门静脉和肠道血流量分别增加 37 9%、98 6 %和 47 5 % (P <0 0 0 1 ) ,肝灌注则增加 68 2 5 % (P <0 0 0 1 ) ;进一步复苏至PAOP为 (1 2 1± 1 4)mmHg,肝动脉、门静脉和肠道血流量分别继续增加至 65 9%、1 32 1 %和 85 0 % (P <0 0 0 1 ) ,肝灌注继续增加至 98 95 % (P <0 0 0 1 ) ;液体复苏明显降低血乳酸 (P <0 0 5)。结论 感染性休克后内脏灌注减少是不均一的 ,液体复苏后血流的增加亦是不同步的 ;液体复苏可基本恢复肝脏灌注 。
