In 1986, Vern L. Katz, Deborah J. Dotters, and William Droegemueller published “Perimortem Cesarean Delivery,” an article in which they developed the Four Minute Rule for perimortem cesarean sections. The Four Minute Rule states that if a pregnant woman’s heart stops beating, physicians should begin an operation to deliver the fetus within four minutes and aim to have the fetus delivered within five minutes of cardiac arrest. Although cardiac arrest during pregnancy is uncommon, it can happen when pregnant women experience trauma, blood clots, infection, or have preexisting heart conditions. In the article, the authors emphasize how the Four Minute Rule increased maternal and fetal survival rates and decreased cases of severe fetal brain damage. The article “Perimortem Cesarean Delivery” was the first article to present the Four Minute Rule, which has influenced international guidelines and become the standard for maternal resuscitation and fetal survival in emergency medicine, operating rooms, and many other aspects of medical practice.

Jesse Bennett, sometimes spelled Bennet, practiced medicine in the US during the late eighteenth century and performed one of the first successful cesarean operations, later called cesarean sections, in 1794. Following complications during his wife’s childbirth, Bennett made an incision through her lower abdomen and uterus to deliver their infant. Bennett’s biographers report that his operation was the first cesarean section where both the pregnant woman and the infant survived. Previously, physicians used cesarean sections to save the fetus from a pregnant woman who had already died during childbirth. Bennett successfully performed a cesarean section, a procedure used worldwide in the twenty-first century when a vaginal delivery is not possible or would pose a risk to the woman or fetus.
