The induced model was unstable.

In patients with acute PE, if IV UFH is chosen, we recommend that after an initial IV bolus (80 U/kg or 5,000 U), it is administered by continuous infusion (initially at dose of 18 U/kg/h or 1,300 U/h) with dose adjustment to achieve and maintain an APTT prolongation that corresponds to plasma heparin levels of 0.3 to 0.7 IU/mL anti-Xa activity by the amidolytic assay rather than administration as IV boluses throughout treatment, or administration without coagulation monitoring (Grade 1C).

急性PE患者，如果选择IV UFH，我们推荐初始快速注射80U/kg或者5000U，继之以18 U/kg/h 或 1，300 U/h持续静滴。根据APTT延长，或者监测血浆肝素水平在0.3'0.7IU/ml， amidolytic assay 分析抗Xa因子活性来调整UFH剂量，而不能持续静脉注射治疗，或者不监测凝血功能（1C）。
