摘要
目的观察比较急性等容量血液稀释(ANH)和急性高容量血液稀释(AHH)对老年骨科手术患者血流动力学的影响。方法将60例拟行骨科手术的老年患者分为ANH组与AHH组,麻醉后分别予以急性等容量血液稀释和急性高容量血液稀释,观察两组不同时间点血流动力学指标收缩压(SBP)、舒张压(DBP)、中心静脉压(CVP)、心率(HR)的变化,比较两组术中出血量、输血量。结果两组术中的SBP、DBP、CVP及HR均保持稳定,各时间点对比,无统计学差异(P>0.05)。两组术中出血量比较,无统计学差异(P>0.05);ANH组的术中输血量明显少于AHH组(P<0.05)。结论两种血液稀释方法均能维持老年骨科手术患者的术中血流动力学稳定,其中急性等容量血液稀释方法在减少输血量方面明显优于急性高容量血液稀释,能够降低异体输血产生不良反应的风险。
Objective To observe and compare the effects of acute normovolemic hemodilution（ANH） and acute hypervolemic hemodilution（AHH） on hemodynamics in senile patients undergoing orthopedics surgery. Methods A total of 60 senile patients to undergo orthopedics surgery were divided into ANH group and AHH group. After anesthesia, the two groups received ANH and AHH respectively. The changes in systolic blood pressure（SBP）, diastolic blood pressure（DBP）, central venous pressure（CVP）, and heart rate（HR） and other hemodynamic indicators in the two groups were observed at different time points. Results The SBP, DBP, CVP and HR in the two groups were stable, and there was no significant difference between the two groups at the time points（P〉0.05）.There was no statistical difference in intraoperative blood loss between the two groups（P〈0.05）. The intraoperative blood transfusion in the ANH group was significantly less than that in the AHH group（P〈0.05）. Conclusion Both hemodilution methods can maintain stable hemodynamics in senile patients undergoing orthopedics surgery, but ANH method is better than AHH method, for it can reduce the amount of blood transfusion significantly and reduce adverse reaction after allogenetic blood transfusion.
