Description
Summary:The aim of this study was to examine the association between delivery mode and severe maternal and neonatal morbidity in singleton term breech births. This nationwide population-based cohort study includes 41 319 singleton term and post-term breech births (37 + 0–42 + 6 gestational weeks) in Sweden from 1998 to 2016. Data was retrieved from the Swedish Medical Birth Register. The primary outcomes were two separate composite outcomes, maternal and neonatal severe morbidity. Secondary outcomes were separate severe maternal and neonatal morbidity outcomes. Hospitalization and out-patient visits during childhood were also analyzed in ages 0–5 years. Logistic regression was used to estimate unadjusted and adjusted odds ratios (aOR) with 95% confidence intervals (CI) of severe maternal and neonatal morbidity in women with vaginal breech birth or intrapartum cesarean section. Women with a prelabor breech cesarean section was used as the reference group. No difference between vaginal delivery and prelabor cesarean section was seen regarding maternal morbidity. Intrapartum cesarean section was associated with elevated odds for maternal morbidity (aOR 1.27, 95% CI 1.10–1.47) compared with prelabor cesarean section. A similar result was observed for vaginal delivery and intrapartum cesarean section combined (aOR 1.29, 95% CI 1.11–1.50). Vaginal delivery was associated with higher odds for composite neonatal morbidity (aOR 1.85, CI 1.54–2.21) and most separate outcomes, as well as increased number of hospital nights and out-patient visits during first year of life, compared with prelabor cesarean section. Prelabor cesarean section in breech births improved short-term neonatal health without increasing risks for severe maternal short-term complications.
