Cesarean section was not always having a baby. For that matter, it was not always having a mother, either. The operation has been done even before the time of the Romans, but got its name not from Julius Caesar, who was not born by cesarean section, but from the Latin caedere-"to cut." Gnaeus Pompeius decreed that the baby be removed from the mother by an abdominal incision after the mother had died, so that they could be buried separately.' The first recorded performance of a cesarean on a living woman took place in 1500, not by a doctor o r a midwife, but by a sow gelder named Jacob Nuffer, who knew nothing about midwifery. When his wife could not give birth, and the midwives and surgeons gave her up for lost, he did the obvious thing. She lived t o the age of 77, but we have n o record of what happened t o the baby.l From the beginning of the 17th Century, the operation was tried several times as a last resort, but the results were not always as good as Nuffer's. In 1784 Aitken wrote, after a good description of the technique, "This formidable operation, intended to save mother and child, has been performed during many centuries with various success. In Britain, it has never fully had the desired effect, all the mothers having died."* This may give a little background t o the concepts we have about this operation, and the fears engendered by the very name today. And yet recently, we have seen an incredible change in the attitude of obstetricians t o cesareans, to the extent that while as recently as 10 years ago, we obstetricians had the difficult job of explaining t o our peers why a cesarean was done, today we have the even more difficult job, often, of explaining why a cesarean was not done. Depending o n the hospital, from 10-1 5% or more of births are by cesarean today. Whether o r not this is justified is another concern. The fact is that today, not only is having a section having a baby, but often, having a baby is having a section.Technically, a cesarean birth is simple and safe. Modern anesthesia has improved to the point where anesthetic risks are virtually nil. The risks of hemorrhage have been reduced with improved surgical techniques and blood transfusion. The fears of infection have been counterbalanced by proper attention to asepsis, and to the antibiotics we have available. The classical operation, with its dangerous and weak incision into the upper segment of the uterus, has almost completely disappeared. It has been replaced with an incision into the lower uterine segment, which is strong and virtually without risk of rupturing in a subMurray W .
