在降低倒母亲死亡率的防治措施中,及时补偿分娩时的失血起着很大的作用。但是众所周知,在大失血时常因靜脉痙攣或因产妇浮腫和肥胖找不到明显的靜脉而不能及时輸血,且常因企圖寻找靜脉而貽誤宝貴的时机,以致产妇可能死亡。在这种情况下,如不作靜脉切开輸血,那只有将血液注入骨髓內才能及时。經骨髓也和一般靜脉输血一样,可注入任何量的血液。 In the prevention and treatment measures to reduce the mortality rate of unwanted mothers, timely compensation for blood loss during labor plays a significant role. But it is well-known that maternal deaths can occur as a result of venous spasms or the inability to find transmissible blood transfusions due to puffy and obese males in periods of major blood loss, and the often-missed timing of attempting to find veins. In this case, if not for venous transfusion, that only the blood into the bone marrow can be timely. Bone marrow, like normal venous transfusions, can be filled with any amount of blood.
