The median maternal age was 30 years (range 17\u201341) and 50% were primigravidae. Seven pregnancies were complicated by polyhydramnios and four deliveries were complicated by shoulder dystocia.

Six women (6\/26; 23%) had a pre\u2010labour intrauterine fetal death and nine women (9\/26; 35%) had an intrapartum fetal death. Median neonatal survival time was 55 min (range 10 min to 8 days).
