如何根据失血量计算输血量
从来没考虑过这个问题只是看出的多了》700-800,看看血气给输
输血前一般测个血常规,根据血色素的值来指导输血,一般血色素低于7克,就可以输血了。建议你看下《输血指南》,上面都有的。
如果没有血气分析,根据占血容量比例来输? 看情况吧,出的多了,血色素不好也得输血
一般出血少于800ml。不需要输血。失血量多少就补多少 我们都是根据血气分析的结果来指导输血的 根据血气青壮年低于7g输血 in general, it depends, pt's medical conditions, natureof surgery, and pt's tolerance during the procedure, availability of blood, etc.
if patient is health, procedure is simple and no more on going bleeding, then 800 bloodcan be substituted by fluids without transfusion.normally,if pt can tolerate, give either LR or Saline 3 times of blood lost. but for major cardiopulmonary disorder,pt has on going bleeding and pt showing the signs of poor tolerance for acute blood lost and HB is less than 6 or 7. then transfusion is necessary.
