血小板减少如不低于20×19~9/L通常并不引起严重的出血,除非伴有血小板功能缺陷、血液凝固障碍或有引起出血的局部因素。有人在白血病患者回顾性的研究中发现,当血小板计数低于20×10~9/L时出血率显著上升。输注血小板(PT)可用作预防性的或治疗性的。预防性PT的适应症是:①血小板减少或血小板功能缺陷患者需施行手术、活检或遭受严重外伤时,②快速可逆性的严重血小板减少患者当处于有出血危险的阶段时,属于这一范畴的患者包括血小板计数 20×10~9/L而伴有下列任一种情况者:a,推测是药物引起的急性血小板减少。b,急性白血病在发病时或接受化疗时,c,恶性疾病用细胞毒药物化疗时出现的血小板减少。d,“大量”输血后出现的血小板减少。e,应用一种体外泵引起的血小板减少。这些推荐所依据的临
Thrombocytopenia, such as not less than 20 × 19 ~ 9 / L usually does not cause severe bleeding, unless accompanied by defects in platelet function, blood clotting disorders or bleeding-causing local factors. A retrospective study of leukemia was found in patients with platelet count below 20 × 10 ~ 9 / L bleeding rate increased significantly. Infusion of platelets (PT) can be used as a prophylactic or therapeutic agent. Preventive PT indications are: ① thrombocytopenia or platelet defects in patients undergoing surgery, biopsy or severe trauma, ② rapid reversible severe thrombocytopenia in patients at risk of bleeding stage, fall into this category Patients included a platelet count of 20 × 10 ~ 9 / L with any of the following: a. Speculative drug-induced acute thrombocytopenia. b, acute leukemia at the time of onset or chemotherapy, c, malignant disease with cytotoxic drug chemotherapy occurs when thrombocytopenia. d, thrombocytopenia occurred after “massive” blood transfusions. e, using an extracorporeal pump-induced thrombocytopenia. These recommendations are based on the Pro
