近年来在颌面外科做正颌手术时多采用输自家血的方法。一般在术前采400ml血贮存备用。但采血后什么时间为手术最佳时期尚无报道,作者就此问题作了血液生理学方面的研究。对象及方法以在红十字会血站献血的8名健康女性成人为研究对象。分别在采血前、采血后第1、3、5、7、14、21、30天做下列项目的血液学检查。结果末梢血的血液学变化:①红细胞数:采血后第2天明显减少,14天开始增加,21天再度减少,呈最低水平,30天恢复原水平。②血色素(Hb):同红细胞。③血细胞比容(Hct):采血第2天明显减少,30天恢复正常。④网状红细胞比例:采血第3天明显上升,14天以
In recent years, orthognathic surgery in maxillofacial surgery to use more blood transfusion method. Preoperative mining 400ml blood reserve. However, after blood sampling for the best period of surgery has not been reported, the author made a blood physiology research on this issue. Subjects and Methods Eight healthy female adults who donated blood at the Red Cross blood bank were included as study subjects. Blood samples were collected on the 1st, 3rd, 5th, 7th, 14th, 21st and 30th day before blood sampling. Results Hematological changes of peripheral blood: ① erythrocyte number: blood 2 days after significantly reduced, 14 days began to increase again reduced 21 days, was the lowest level, 30 days to restore the original level. ② hemoglobin (Hb): the same red blood cells. ③ hematocrit (Hct): Blood 2 days significantly reduced, 30 days returned to normal. ④ reticulocyte ratio: Blood 3 days increased significantly, 14 days
