A survey of risk factors and intervention strategies for postpartum hemorrhage in elderly parturients
Objective To analyze the risk factors and intervention strategies for postpartum hemorrhage in elderly parturients.Methods 98 elderly parturients who gave birth were selected as the subjects,and the incidence of postpartum hemorrhage was counted;a self-constructed general information questionnaire was used to collect information from the patients and analyze the risk factors of postpartum hemorrhage in elderly parturients.Results Among the 98 parturients,a total of 19 cases experienced postpartum hemorrhage,accounting for 19.39%(19/98).Univariate analysis showed that there was no significant difference in the age,gestational week,number of pregnancies,pre-pregnancy body mass index(BMI),maternal type,smoking history,drinking history,gestational diabetes mellitus,and the number of fetuses between parturients with and without postpartum hemorrhage(P>0.05).Comparison of placenta previa,uterine atony,neonatal weight,mode of delivery,gestational hypertension,platelet count,history of uterine cavity surgery,psychological state,painless delivery between parturients with and without postpartum hemorrhage showed statistical difference(P<0.05).Logistic regression analyses were performed using items that were statistically different in a single factor analysis as the independent variable and whether postpartum hemorrhage occurred as the dependent variable.The results showed that cesarean section[OR=12.708;95%CI=(3.745,43.124)],neonatal weighing>4 kg[OR=14.950;95%CI=(4.627,48.306)],gestational hypertension[OR=10.212;95%CI=(3.222,32.368)],placenta previa[OR=12.708;95%CI=(3.745,43.124)],uterine atony[OR=6.817;95%CI=(2.201,21.117)],history of uterine cavity surgery[OR=6.392;95%CI=(2.144,19.053)],and platelet count<100×109/L[OR=24.391;95%CI=(5.228,113.791)],poor psychological state[OR=6.830,95%CI=(2.067,22.573)],and painless delivery[OR=3.047;95%CI=(1.047,8.867)]were the independent risk factors for the occurrence of postpartum hemorrhage in elderly parturients(P<0.05).Conclusion Cesarean section,neonatal weight>4 kg,gestational hypertension,placenta previa,uterine atony,history of uterine cavity surgery,platelet count<100×109/L,poor psychological state,and painless delivery are independent risk factors for postpartum hemorrhage in elderly parturients.
