#469: Should 38-Week Induction For Big Babies Become A Thing?
Notes de l’épisode
This week, Blyss and Stu take a deep dive into the increasingly popular recommendation of inducing labor at 38 weeks for suspected “big babies”.
Prompted by a recent social media post from a prominent obstetric influencer, they examine two studies being used to justify earlier inductions for "big babies" and ask an important question: do the data actually support the conclusions being promoted?
Along the way, Blyss and Stu challenge listeners to look beyond headlines and social media summaries, examine how studies are designed, and consider whether interventions are being recommended based on meaningful risk reduction, or simply because they can be.
The episode emphasizes the importance of respecting nature's design, individualizing care, and helping families understand the difference between relative risk, absolute risk, and true informed choice.
