Roberto Caldeyro-Barcia studied fetal health in Uruguay during the second half of the twentieth century. Caldeyro-Barcia developed Montevideo units, which are used to quantify intrauterine pressure, or the force of contractions during labor. Intrauterine pressure is a useful measure of the progression of labor and the health of a fetus. Caldeyro-Barcia’s research on fetal health often contradicted common obstetric practices, prompting him to publically challenge practices such as induction of labor using oxytocin, forced pushing during labor, and birth position in which the woman lays on her back during labor. Caldeyro-Barcia’s methods of monitoring intrauterine pressure and development of Montevideo units furthered research in maternal and fetal health and improved the use of medical interventions during labor and delivery.
