“The Present is the Living Total Sum of the Past” Thomas Carlyle
Cesarean Section Wars Etymology The Premier Eponym in Medicine • “Lex Regia ” In early Rome, a legal degree that abdominal delivery be performed upon the hope of saving the child. In the time of the Caesars became “Lex Caeserea.” • “Caedere” (past particle “caesus,”) the Latin word to cut. • The traditional legend of the birth of Julius Caesar. Pliny the Elder, a historian in the first century A.D., stated that the first Caesar was cut from the uterus of his mother. Other historic generals, kings and mythical figures were recorded as having been born by abdominal delivery.
Cesarean Wars • France • 1579 – Paré condemned C/S • 1581 – Rousset. First book on C/S • 1598 – Guillimeau. Child birth or Happy delivery of Women • 1668 – Mariceau against C/S. Warned against “killing the mother to save the child” • 1790 – Baudiloque recorded 31 maternal survivals in 73 C/S • 1797 – Sacombe formed anti-cesarean society
Cesarean Wars • England • 1751 – John Burton. Advocates C/S in cases where “instruments are of no value and the only means we have of saving the mother is by cesarean section.” • 1752 – William Smellie. C/S “ought to be delayed until the women expires and then immediately performed with a view of saving the child.” • 1793 – Hull-Simmons Controversy. Up to the end of the 18th century only 2 surviving mothers in 180 operations in England.

Destructive scissors and crotchets William Smellie, 1754
Case 299 Three Hundred Consultations in Midwifery Robert Lee 1863. London On the 2nd of December 1863, I was consulted to see a patient who was 38 hours in labor with a contracted pelvis, the sacrum almost reaching the symphysis pubis. At 1:30 PM the cervix was not fully dilated. Cesarean section was considered, but we decided to wait for more dilatation. 8 hours later, after more dilatation and confirmation of vertex presentation, craniotomy was attempted. The head was opened and brain escaped. For the next 4 hours every effort was made to extract the head. The bones of the head were broken up, craniotomy forceps were tried, but the head could not be brought through the brim of the pelvis. The crotchet was then passed into the mouth, but all the bones of the face came away with the remainder of the head still above the brim.
Case 299 Three Hundred Consultations in Midwifery Robert Lee 1863. London At 1:30 AM being completely exhausted, we resolved to give the patient some hours repose. In the afternoon three eminent practitioners were consulted. Two were in favor of cesarean section, after another attempt with the crotchet. The patient asked to be insensible with chloroform before another attempt was resumed. After 4 hours, “I succeeded in dragging the shattered bones of the head into the world.” A cord was tied around the neck for traction, and an attempt was made to reach the arms with the crotchet. All efforts to deliver the trunk were unsuccessful and being thoroughly exhausted, it was resolved not to persevere. Next morning the patient was in a moribund state, and died in the evening. At autopsy, the distance from the base of the sacrum to the symphysis pubis was 1 ½ inches.

The Place of Cesarean Section:Irving, 1937 Conclusions: • “In cases where there is a fair choice between pelvic delivery and Cesarean section one should consider well the increased risk to the mother, who is vastly more important than the infant, before one performs an operation which gives the baby an advantage [if it increases the risk to the mother]” • “Cesarean section in the United States is accompanied by a 5.8% mortality.”

Battle lines drawn over C-Sections By Rita Rubin, USA TODAY • “For some women, birth has become the latest battleground for reproductive rights.” • “At a growing number of hospitals, women are being forced to schedule a repeat Cesarean Section just because they already had one. Doctors and hospitals say they fear lawsuits if they allow a patient to attempt a vaginal birth after a C-Section — called a VBAC — and something goes awry.”

Cultural Selection of Cesarean Section • Change in Technology • Change in Social Conditions and Norms
Darwinian Natural Selection of Cesarean Section • Human Birth is Very Difficult • A “Tight” Squeeze • Human Birth is Integral to the Key Processes in Evolution of Homo Sapiens • Upright Posture • Brain Enlargement and Development
Evolutionary Changes in Human Birth • Enlargement of human pelvis (at it’s limit) • Internal rotation of human babies head in labor (only primate or mammal with this evolutionary mechanism) • Slower development of fetus including fetal head. Human brain at birth is less than one-fourth it’s final adult size. Other primates at birth average about one-half adult size. • Shorter gestation for fetal development
Natural Selection of Shorter Gestation • Major feature of human evolution (in utero and in childhood) is slowing of development • If human birth occurred at the same fetal development of physical characteristics, birth in humans would occur not at 9 months but at 16 to 17 months of gestation. • Human babies at 9 months are essentially “still an embryo.” • Birth at 9 months as compared to other primates is preterm as a result of evolution of upright posture and brain size.
Natural Selection Today • Due to changing medical practice • Increased Cesarean sections due to changes in technology and social values is selecting genes for smaller pelvises and larger babies • Neonatal maternal fetal medicine through natural selection is increasing preterm labor
