Can Propranolol Rescue Labor?

It has been well reported that rates of elective induction have risen nationally and internationally since the adoption of the ARRIVE trial. But as medicine is at times controversial, some studies have suggested an increase in cesarean section rates with elective induction of labor at 39 weeks. While we will briefly discuss those studies, they are not the focus of this episode. However, as induction of labor becomes more common place, there has been renewed interest in use of adjuvant medications to augment induction success. One of those medication is propranolol. Can giving a beta-blocker help with uterine contractility? The data is conflicting with recent evidence saying “No!“. In this episode, we’re going to put the evidence on trial and present both arguments: one as plaintiff, and one argument as the defense for our shared client, which is propranolol. Is propranolol guilty of its charges of being a labor stimulant? Or is it innocent of all charges? Let’s let the data decide.
