Abstract

The risk of heavy bleeding after a miscarriage is higher in women undergoing medical management compared with surgical. According to the literature, oxytocin receptor mRNA expression in the myometrium is not well formed during early gestation. Adrenaline may be considered in miscarriage which remains refractory to uterotonics and where bleeding from the placental bed may contribute to haemorrhage, before proceeding to surgical intervention. It is used in various settings to control bleeding in gynaecological procedures. A 34-year-old woman in her third pregnancy presented at 15 + 1 weeks of gestation with an open cervical os and bulging membrane. Within three hours of admission, she passed the fetus but failed to deliver the placenta and continued to bleed. She was taken to theatre for surgical management of miscarriage. The bleeding persisted following suction evacuation and despite the standard dose of oxytocin, and misoprostol uterotonics were given. Because the source of bleeding could be the placental bed, potentially low lying at this stage, a 4.4 ml prefix combination of 12.5 μg/ml adrenaline (1:80,000) and lidocaine (20 mg/ml) was administered as an intracervical block equally at four quadrants at the level of the cervical isthmus. This arrested the bleeding immediately and controlled the bleeding until discharge. This technique has not been described previously, which we believe causes vasoconstriction of the placental bed.
