急性高容量血液稀释在老年患者中的可行性与安全性

Feasibility and Security of Acute Hypervolemic Hemodilution in Old Patients

术前急性高容量血液稀释可明显减少手术失血和输血量，防止输血相关疾病，缓解血源紧张。急性高容量血液稀释使机体处于超容状态，由于老年患者心血管系统的衰老性退变，心脏贮备功能及对循环血量改变的适应能力下降，实施血液稀释则会有所顾虑。但是无心肺疾患的老年可承受急性高容量血液稀释带来的心肺负荷增加，可改善器官组织的血流量和氧供。本文从各方面综述了急性高容量血液稀释可安全应用于无心肺疾病的老年患者。

The purpose of preoperative acute hypervolemic hemodilution can obviously decrease the ca- pacities of hemorrhage and transfusion during operation. It also can avoid disease related to transfusion and solve the sparsity of hematocyte. Acute hypervolemic hemodilution makes the body to be in hypervolemic state. It is anxious that acute hypervolemic hemodilution is applied to the old patients, because of the decrepit degeneration of cardio - vascular system and the decline of cordis reserve. The old patients having no cardiop- ulmonary disease can endure augment of cardiopulmonary load for acute hypervolemic hemodilution. Acute hypervolemic hemodilution can improve oxygen-supply of organ and tissue. This article roundly expatiates the view that acute hypervolemic hemodilution can be used for the old patients without eardiopulmonary disease in security.
