Clinical characteristics and pregnancy outcomes of women with postplacental hematoma versus subchorionic hematoma
Objective To explore the clinical characteristics of women with retroplacental hematoma and subchorionic hematoma,and to compare their pregnancy outcomes to enhance the clinical understanding of such hematomas.Methods The clinical data of 160 women with intrauterine hematoma who delivered at Qilu Hospital of Shandong University from April 2021 to September 2022 and were found in the second trimester of pregnancy were collected and analyzed retrospectively.They were 20-40 years old.The gestational weeks were 12-25+2 weeks.According to the types of hematoma,they were divided into a retroplacental hematoma group and a subchorionic hematoma group,with 80 cases in each group.The clinical characteristics and pregnancy outcomes of the two groups were comprehensively compared and analyzed.t test and x2 test were used for the statistical analysis.Results The incidence of fetal distress in the retroplacental hematoma group was higher than that in subchorionic hematoma group[13.75％(11/80)vs.2.50％(2/80)],with a statistical difference(x2=6.782,P=0.009).The incidence of full-term pregnancy in the retroplacental hematoma group was lower than that in the subchorionic hematoma group[56.25％(45/80)vs.87.50％(70/80)],with a statistical difference(x2=19.324,P＜0.001).The incidence of premature delivery in the retroplacental hematoma group was higher than that in the subchorionic hematoma group[27.50％(22/80)vs.5.00％(4/80)],with a statistical difference(x2=14.879,P＜0.001).The incidences of premature rupture of membranes,abnormal placenta,and residual placenta in the postplacental hematoma group were higher than those in the subchorionic hematoma group[40.00％(32/80)vs.12.50％(10/80),37.50％(30/80)vs.12.50％(10/80),and 31.25％(25/80)vs.7.50％(6/80)],with statistical differences(x2=15.626,13.333,and 14.444;all P＜0.001).The gestational weeks of delivery in the postpartum hematoma group was shorter than that in the subchorionic hematoma group[(36.12±3.02)weeks vs.(38.12±2.89)weeks],with a statistical difference(t=4.280,P＜0.001).The newborns'body weight in the postpartum hematoma group was lower than that in the subchorionic hematoma group[(3 025.25±562.02)g vs.(3 323.21±578.25)g],with a statistical difference(t=3.096,P=0.002).The incidence of neonatal diseases(neonatal pneumonia,neonatal hyaline membrane disease,and neonatal hemolysis)in the retroplacental hematoma group was higher than that in the subchorionic hematoma group[17.91％(12/67)vs.2.70％(2/74)],with a statistical difference(x2=9.093,P=0.003).Conclusions There are significant differences between women with retroplacental hematoma and subchorionic hematoma in hematoma volume,delivery gestational weeks,and pregnancy outcomes;the former is more likely to cause adverse pregnancy outcomes,so it is necessary to be vigilant and take effective intervention measures in time to reduce the incidence of adverse pregnancy outcomes.
