摘要: 目的 对大量输血前后血清钙离子浓度的变化情况进行分析,探讨输血后低钙血症发生的影响因素。方法 选取本院近1年来收治的75例大量输血患者,对患者在输血治疗前后测定的血钙浓度进行观察,同时分析输血前后血清酸碱度变化,探究低钙血症变化的影响因素。结果 输血后的血清钙离子浓度显著低于输血前(P<0.05),输血后24 h有所回升,但仍低于输血前水平(P<0.05)。Logistic回归分析显示,输注悬浮红细胞(red blood concentrates,CRCs)、新鲜冰冻血浆(fresh frozen plasma,FFP)量,输血后阴离子间隙(anion gap,AG)是导致输血后低钙血症发生的重要因素,输血后AG是输血后发生重度低钙血症的主要影响因素(P<0.05)。结论 输血后低钙血症的发生与输入血制品的量有直接关系,且大量输血患者发生低钙血症的概率较高。治疗过程中需严密监测患者血钙水平及血液酸碱度的变化,有助于减少输血后低钙血症的发生。

Abstract: Objective To investigate the changes of serum calcium concentration(iCa) before and after massive transfusion,and discuss the influencing factors of the occurrence of hypocalcemia. Methods 75 cases of patients receiving massive blood transfusion in Xiangya Hospital from May 1,2015 to Apr 30,2016 were selected,collected serum calcium concentration of patients before and after massive transfusion,and analyzed changes of serum AG during massive transfusion,researched on the factors affecting the incidence of hypocalcemia. Results Student t test between groups showed that the serum calcium concentration(iCa) was significantly lower than that before the blood transfusion (P<0.05),iCa after the blood transfusion 24 hours rise again,but it was still lower than that before blood transfusion (P<0.05). Logistic regression analysis showed that the amount of blood product input and AG after blood transfusion (blood acidity after transfusion) are important factors leading to the occurrence of hypocalcemia after massive transfusion,AG after blood transfusion is main influencing factor of the severity of hypocalcemia(P< 0.05). Conclusion Hypocalcemia has direct relationships with the amount of blood products input (P<0.05),while patients receiving massive transfusion have higher probability to suffer from hypocalcemia. Monitoring the change of iCa and blood pH closely during treatment can reduce the occurrence of hypocalcemia and other complications after massive transfusion.
