有效循环血量

有效循环血量减少降低常因大量的出血或机体内液体丢失，或者是第三间隙内有大量的液体积聚于而引起。

Uncontrolled hemorrhagic shock because of massive bleeding or fluid loss , or large amounts of fluid accumulation in the third clearance , results in the decrease of effective circulating blood volume .

【结论】放腹水后患者舒张压、平均动脉压下降，24h尿量增加，其原因可能与放腹水后血管阻力下降、体内有效循环血量增加有关。

【 Conclusion 】 The decrease of diastolic pressure 、 mean arterial blood pressure and increase of urine volume in patients after paracentesis may be related to the decreased resistance of blood vessel and the increased effective volume of blood .

提示0.75%布比卡因硬膜外麻醉行子宫切除术ANP和RAAS的变化，在维持和调节有效循环血量及外周血管阻力中发挥着重要的作用。

It is concluded that the change of the levels of ANP and RAAS in the patients undergoing hysterectomy with 0 75 % bupivacaine EA plays an important role in maintaining and regulating effective circulatory blood volume and peripheral vessels resistance .

结论在CVP监测下，实施加压快速扩容法是救治失血性休克的重要措施，可迅速恢复病人有效循环血量，维持重要器官组织细胞的灌注，提高抢救成功率。

Conclusion With the monitoring of CVP , the pressured rapid volume expansion is an effective treatment for hemorrhagic shock . With the pressured rapid volume expansion , the circulating blood volume of patients can be recovered rapidly and the perfusion of important organs , tissues and cells be maintained .

在以往的研究中，我们曾观察到家兔在有效循环血量急剧减少的下体负压条件下血压调节能力有很大个体差异。

In previous studies we have observed significant individual difference of blood pressure regulating ability in rabbits under LBNP which sharply decreased the circulatory blood volume .

液体复苏是治疗失血性休克的重要措施，旨在增加有效循环血量、改善微循环，减轻组织和器官的损伤。

Fluid resuscitation is an essential component of therapy for hemorrhagic shock . The aim of fluid resuscitation is to expend effective blood volume , increase perfusion in microcirculation , and to alleviate injuries in tissue and organ .

即强调在创伤失血性休克早期应积极快速地给予大量液体复苏，迅速恢复有效循环血量，尽可能的将血压恢复到正常水平。

The traditional guideline of treatment for hemorrhagic shock included aggressive , rapid , and large fluid infusion , which meant to restore effective circulation blood volume and maintain the blood pressure at a normal or near normal level .

凡是由一种或多种病因而引起的机体组织灌注量不足，有效的循环血量急速减少，细胞功能代谢紊乱和细胞功能受到损害的病理和生理的综合征，称为休克。

One shock is caused by a variety of causes of effective circulating blood volume , inadequate tissue perfusion , impaired cell metabolic disorder and pathological syndrome .
