骨科内固定手术后外周血象中血红蛋白值升高的研究

Study on The Variation of Hemoglobin in Patients with Orthopedic Internal Fixation Surgery

目的观察骨折内固定手术后红细胞、血红蛋白等数值变化,分析术中补液量对外周血象的影响。方法选取8例骨折内固定手术患者,检测分析患者术后24h、48h或72h红细胞、血红蛋白、白细胞、血小板等数值的变化。结果 8例骨折行复位固定术的患者术后24h,48h、72h红细胞、血红蛋白有一定波动,术中液体量对红细胞、血红蛋白有稀释作用,术后24h后红细胞、血红蛋白均明显升高。结论骨科内固定术补液量对血红蛋白有一定的稀释作用,术后血红蛋白逐渐恢复正常。

Objective To observe the change of erythrocytes and hemoglobin after fractural internal fixation surgery and analyze the effect of volume of liquid infusion on peripheral blood of patients during operation.Methods The levels of red blood cells(RBCs),hemoglobin,white blood cells and platelets at 24h,48h or 72h following operation were detected and analyzed in 8 patients.Results The number of RBCs and concentration of hemoglobin were fluctuated on 24h,48h,and 72h post-operation.The volume of infusion on operation had impact on the RBCs count and concentration of hemoglobin due to the blood dilution within 48h-72h,which increased significantly after 24h post-operation.Conclusions The volume of fluid infusion in orthopedic patients has a diluted effect on RBCs and hemoglobin but may gradually recover after operation.
