Interventions During or Following Birth

Pregnancy ends when the baby exits the mother’s womb. Labour is the process of childbirth, from initial contractions to the delivery of the baby. Birth of the baby can occur naturally, through the birth canal, or can occur via a Caesarean section. Additional interventions may be used during the birth process to help the mother deliver.

According to the Better Outcomes Registry & Network (BORN) for 2016, 61.3% (59.9%, 62.6%) of Simcoe Muskoka women had spontaneous onset of labour. Approximately one-quarter of women were induced (25.3% (24.1%, 26.5%)) and fewer than one in six (13.5% (12.5%, 14.4%)) had no labour. These rates were similar to Ontario as a whole, where 60.4% (60.1%, 60.6%) of women had spontaneous onset of labour in 2016.
