Analysis of the risk factors of the severe hemorrhage during labor induction of pregnant women with pregnancy-induced hy-pertension
Objective:To study the risk factors of the severe hemorrhage during labor induction of pregnant women with pregnancy-induced hypertension(PIH).Methods:The clinical data of 200 pregnant women with PIH who had been given labor induction from January 2020 to December 2022 were selected in this study.According to the situation of the hemorrhage during labor induction,these women were divided into 34 women with severe hemorrhage(Hb de-creased by 40g/L)in group A and 166 women without severe hemorrhage in group B.The risk factors of the severe hemorrhage of the women with PID during labor induction were analyzed.Results:By univariate analysis,there were no significant differences in the age,the body mass index(BMI)value,the history of delivery,the early-onset pre-eclampsia,the Hb level at admission,the history of induced labor or abortion,the gestational weeks at delivery,the mode of labor induction,the malnutrition rate,the number of deliveries and the values of systolic blood pressure and diastolic blood pressure of the women between the two groups(P>0.05).There were significant differences in the mode of delivery,the application of oxytocin during delivery,the time from induction to delivery and the weight of the newborn of the women between the two groups(P<0.05).Multivariate unconditional logistic analysis showed that the cesarean section,the reduced oxytocin used during labor,the longer time from induction to delivery,the higher neo-natal weight and the cesarean section history of the women with PIH were all the independent risk factors of their se-vere hemorrhage during induced labor(P<0.05).Conclusion:There are many independent risk factors of the severe postpartum hemorrhage of the pregnant women with PIH,so the effective interventions should focus on these risk fac-tors for the women with PIH in clinic.
