Objective:To evaluate the blood loss and blood transfusion of the acute hypervolemic hemodilution (AHH), and the acute hypervolemic hemodilution combinate controlled hypotension (CH) undergoing the corrective scoliosis surgery of intraoperative period .
在脊柱侧弯手术的麻醉中对两组患者分别行单纯急性高容血液稀释(AHH)与急性高容血液稀释联合控制性降压(CH)时,比较两组患者术中的失血量和输血量。
Using two models of wind accretion,we calculate the relations between surface carbon Abumdance of secondary stars and the orbical periods for CEMP stars and CH stars,and calculate the relations of contamination factor R with orbital periods,and estimate variation of binary separation vs.
利用KOMIYA和LIU的2个星风吸积模型计算了富碳极贫金属星(CEMP星)和CH星表面C丰度与轨道周期P终值的关系、污染因子R同轨道周期P终值的关系,以及轨道半长轴A随伴星质量M2的变化。
