摘要
目的:研究二次负压吸引对红细胞计数及形态变化的影响,探讨一次性胸腔闭式引流瓶在自体血回收中应用的可行性。方法:选择15例外伤性腹腔内出血患者为研究对象,把每例患者腹腔内血液经二次负压吸引(P2)者为实验组,一次负压吸引(P1)者为对照组,比较两组红细胞计数(RBC),血红蛋白(Hb)及平均红细胞体积(MCV)的变化,涂片染色在光镜下观察红细胞形态有无变化。结果:在相同负压(≤0.02mPa)下,实验组与对照组的红细胞计数(RBC),血红蛋白(Hb)及平均红细胞体积(MCV)进行比较,三者差异均无统计学意义(P>0.05),光镜下观察显示红细胞形态变化亦不明显。结论:自体血回收中二次负压吸引与一次负压吸引(压力≤0.02mPa)对红细胞计数及形态均无明显影响,一次性胸腔闭式引流瓶在自体血回收中应用是可行的。
Objective：To evaluate the impact of secondary negative pressure attraction on red blood cell count and morphological changes, and the feasibility of the application of one-time closed thoracic drainage bottles in autologous blood recovery.Methods：Fifteen patients of traumatic abdominal cavity bleeding were studied. The twice intra-abdominal negative pressure suction blood（P2） of each patient was the experimental group, and only one time negative pressure suction （P1） was the control group. The red blood cell count （RBC）, hemoglobin （Hb）, mean corpuscular volume （MCV） and changes in oil-immersed smear staining patterns were comparatively analyzed in each group.Results：Under the same negative pressure （≤ 0.02mPa）, the difference of the red blood cell count （RBC）, hemoglobin （Hb）, mean corpuscular volume （MCV） and changes in oil-immersed smear staining patterns of the two groups were not statistically significant （P〉0.05）. There was no obvious morphological change on red blood cells in each group, Conclusion：There is no significant adverse effect on red blood cell count and morphology in the autologous blood recovery with twice suction （pressure ≤ 0.02 mPa）. The one-time closed thoracic drainage bottle can be used for the autologous blood recovery.
