Maternal and neonatal outcomes of repeated antepartum bleeding in 493 placenta previa cases: a retrospective study
<p> To explore the effect of antepartum bleeding caused by PP on pregnancy outcomes.</p> <p> We retrospectively analyzed 493 pregnant women complicated with PP. Patients were divided into antepartum repeated bleeding and non-bleeding groups. Maternal characteristics and pregnancy outcomes were compared.</p> <p> The risk of antepartum hemorrhage was 2.038 times higher when gravidity was 5 (95% CI 1.104–3.760, <i>p</i> = .023). Pregnant women with a history of more than three intrauterine procedures had a 1.968 times higher risk of antepartum hemorrhage (95% CI 1.135–3,412, <i>p</i> = .016) compared to pregnant women without any intrauterine procedures. The risk of antepartum bleeding was found to be decreasing with the pregnancy advancing; When the placenta edge was noted to be over cervical os, the risk of antepartum bleeding was 4.385-fold than the low-lying plcaenta cases (95%CI2.454–8.372, <i>p</i> = .000). In the respect of maternal outcomes, the repeated bleeding group, the risk of emergency surgery was 7.213 times higher than elective surgery (95% CI 4.402–11.817, <i>p</i> = .000). As for the neonatal outcomes, the risk of asphyxia was 2.970 times and the risk of neonatal intensive care unit (NICU) admission was 2.542-fold higher in repeated bleeding group compared to non-bleeding group, respectively.</p> <p> Obstetricians should be aware of the increased risk of antepartum bleeding especially for ≤34 weeks and placenta edge over cervical os PP patients, they have a higher risk of antepartum bleeding. These women have higher possibility of emergency C-section and need preterm newborn resuscitation.</p>
