Values of the levels of serum calcium,phosphorus and D-dimer of pregnant women before delivery for predicting their u-terine inertia-induced postpartum hemorrhage
Objective:To explore the values of the levels of serum calcium,phosphorus and D-dimer of pregnant women before delivery for predicting their uterine inertia-induced postpartum hemorrhage.Methods:106 women who had delivered in hospital from October 2018 to October 2023 were collected in this study retrospectively.These women were divided in 21 cases with uterine inertia-induced postpartum hemorrhage in observation group and 85 cases without uterine inertia-induced postpartum hemorrhage in control group according to whether the uterine inertia-induced post-partum hemorrhage occurred or not.The medical records of the women in the two groups were collected.The levels of the prenatal serum calcium,phosphorus and D-dimer of the women were compared between the two groups.Multivari-ate Logistic regression analysis was used to screen the risk factors of the uterine inertia-induced postpartum hemor-rhage of the women.The values of the levels of the prenatal serum calcium,phosphorus and D-dimer of the women for predicting their uterine inertia-induced postpartum hemorrhage was analyzed.Results:The levels of the prenatal serum calcium(2.39±0.31 mmol/L)and phosphorus(1.27±0.30 mmol/L)of the women in the observation group were sig-nificantly lower than those(2.66±0.28 mmol/L and 1.53±0.35 mmol/L)of the women in the control group.The pre-natal serum D-dimer level(0.40±0.09 mg/L)of the women in the observation group was significantly higher than that(0.32±0.10 mg/L)of the women in the control group(all P＜0.05).Logistic regression analysis showed that the low serum calcium and phosphorus levels,the high D-dimer level,the advanced age,the high body mass index value and the prolonged labor duration of the women were the risk factors of their uterine inertia-induced postpartum hemorrhage(P＜0.05).The area under the curve(AUC),the sensitivity and the specificity of the combined levels of the serum calcium,phosphorus,and D-dimer of the women for predicting their uterine inertia-induced postpartum hemorrhage were 0.912,95.2％and 50.6％,respectively,and the predictive efficacy of which was significantly higher than that of the serum calcium level,the phosphorus level or the D-dimer level alone(all P＜0.05).Conclusion:The low levels of calcium and phosphorus,and the high D-dimer levels before delivery,the advanced age,the prolonged labor duration and the high body mass index value of the women are the risk factors of their uterine inertia-induced postpartum hem-orrhage.The combined detection of the serum calcium,phosphorus,and D-dimer levels of the women can effectively predicting the occurrence of their uterine inertia-induced postpartum hemorrhage.
