“Given the role of calcium in muscle contractility, we speculate that calcium carbonate may play a role in decreasing labor dystocia for pregnant people undergoing induction of labor by increasing the sensitivity of the uterus to oxytocin.”
“Given that labor dystocia is the most common indication for unplanned cesarean section in the United States, we theorize that calcium carbonate may be a low-risk and promising preventive measure that may decrease the rate of cesarean section.
Anecdotally, there are attestations from clinicians of calcium carbonate being used successfully for laboring people experiencing labor dystocia. The goal of this narrative review was to provide a synopsis of pertinent literature on calcium use in ...
