Abstract

In case of haemorrhage, a combination of low volume fluid resuscitation and permissive hypotension is used to avoid the adverse effects of early aggressive fluid resuscitation. During this phase, occult microvascular hypoperfusion can possibly develop over time. After controlling the bleeding, it is expected that optimization of macrocirculation will result in an improvement in microcirculation. However, this is the case only without alterations in microcirculation regulation. Haemodynamic coherence must be maintained to expect the restoration of microcirculation through systemic haemodynamic-driven resuscitation. However, haemorrhagic shock, reperfusion, traumatic injury and inflammation can damage microcirculation and thus lead to a loss of haemodynamic coherence. In these cases, a systemic haemodynamic-driven resuscitation would not be effective in restoring microcirculation and tissue oxygenation. A real-time technique enabling microcirculation monitoring can create an opportunity for microcirculatory haemodynamic-driven resuscitation to become the gold standard in the future.

摘要

在出血情况下,采用小容量液体复苏和允许性低血压相结合的方法,以避免早期积极液体复苏的不良影响。在此阶段,随着时间的推移,可能会出现隐匿性微血管低灌注。控制出血后,预计大循环的优化将导致微循环的改善。然而,只有在微循环调节无改变的情况下才会如此。必须维持血流动力学的一致性,以便通过全身血流动力学驱动的复苏来恢复微循环。然而,失血性休克、再灌注、创伤性损伤和炎症会损害微循环,从而导致血流动力学一致性的丧失。在这些情况下,全身血流动力学驱动的复苏在恢复微循环和组织氧合方面将无效。一种能够进行微循环监测的实时技术可为微循环血流动力学驱动的复苏创造机会,使其在未来成为金标准。
