New research has shown that planned cesarean deliveries at the mother’s request are safe for low-risk pregnancies and may be associated with a lower risk of adverse delivery outcomes than planned vaginal deliveries, the authors report in the ‘ Canadian Medical Association Journal ‘(CMAJ). The study used data from Better Outcomes Registry & Network (BORN), the Ontario Provincial Birth Registry in Canada. The authors analyzed data from 422,210 low-risk pregnancies over 6 years (2012 to 2018).

There were 46,533 cesarean deliveries, of which 1,827 (3.9%) were planned at the mother’s request; this proportion did not vary during the years of study. Mothers who requested cesarean delivery were more likely to be white, 35 or older, conceived by IVF, give birth to their first baby, and live in a higher-income neighborhood, among others features.

“Our finding that maternal-demand cesarean delivery rates have remained stable in Ontario reassures those concerned about the possible contribution of these deliveries to increasing cesarean delivery rates,” writes Dr. Darine El- Chaâr of the Ottawa Hospital Department of Obstetrics, Gynecology and Newborn Care.

The results also showed that both maternal-requested cesarean deliveries and vaginal deliveries were safe delivery options for mother and baby, and that planned maternal-requested cesarean deliveries were associated with lower risk. of adverse delivery outcomes for both mother and baby than planned vaginal deliveries.

The authors caution that research is needed to understand the possible long-term effects of planned caesarean deliveries. “Although our study addresses concerns related to the immediate implications of planned cesarean delivery, it is necessary to explore the longer-term risks, including their impact on breastfeeding, and the child’s risk of respiratory infections and diseases,” they conclude. .
