危急重症抢救时常会遇到建立静脉通道较困难或较费时及根本不可能的情况,丧失了用药最佳时 机,导致抢救失败。第14版Nelson儿科学记载,建立静脉通道需8分钟,尽管有报告成功率达66％,但1岁以下婴幼儿的成功率不到30％。心跳停止后建立静脉通道更困难。因此人们在寻找更快速、简便且行之有效的给药途径方面做了大量工作,现介绍如下。 骨内输注 骨髓腔内充满网状的海绵状静脉窦,骨内插管输注入骨髓内的药物和液体能迅速弥散入静脉窦,然后经过滋养静脉和导静脉通向全身循环。试验证
Severe emergency rescue often encounter the establishment of venous access is more difficult or time-consuming and simply impossible, the best time to lose medication, leading to rescue failure. According to the 14th edition of Nelson’s Science, it takes 8 minutes to establish a venous access and less than 30% of infants below the age of 1 have a success rate of 66%, despite reports of success. It is more difficult to establish a venous access after a heartbeat has stopped. As a result, a great deal of work has been done to find faster, easier and more effective routes of administration. Intramedullary infusion of bone marrow cavity filled with reticular cavernous sinus, intraosseous infusion of bone marrow into the drug and liquid can quickly dispersed into the sinus, and then through the nourishing veins and leading to the systemic circulation of the venous.
