剖宫产围手术期总失血量与显性失血量、隐性失血量的临床研究

Clinical study on total blood loss,dominant blood loss and recessive blood loss in perioperative period of cesarean section

目的探索剖宫产围手术期患者总失血量与显性失血量、隐性失血量之间的关系。方法收集100例剖宫产的临床病例资料,采用Gross方程计算围手术期总失血量,采用Spearman相关性检验及多元线性回归法分析围手术期失血量与危险因素。结果产妇总失血量与产妇体重、手术耗时、手术前后血红蛋白变化值、手术前后红细胞压积变化值、显性失血量、隐性失血量呈正相关(P<0.05)。结论剖宫产围手术期总失血量的评估应将患者体重、手术耗时、手术前后血红蛋白变化值、手术前后红细胞压积变化值、显性失血量、隐性失血量一并纳入。

Objective To explore the relationship among total blood loss, dominant blood loss and recessive blood loss in perioperative period of cesarean section. Methods The clinical data of 100 cases of cesarean section were collected, the total blood loss in perioperative period was calculated by Gross equation, and the Spearman correlation test and multivariate linear regression method were used to analyze the total blood loss and the risk factors. Results The total blood loss of maternal was positively correlated with maternal weight, operation time, changes of hemoglobin before and after operation,changes of hematocrit before and after operation, dominant blood loss, and recessive blood loss（P〈0.05）. Conclusion The assessment of total blood loss during perioperative period of cesarean section should include patients, weight, operation time, changes of hemoglobin before and after operation, changes of hematocrit before and after operation, dominant blood loss and recessive blood loss.
