Obstetrics - It's all in the delivery

Sign up or log in to save this to your schedule and see who's attending!

During normal parturition, it has been estimated that an average force of approximately 70 kg is required to deliver a bovine fetus. Approximately 40 percent of this pressure is supplied by uterine contractions and 60 percent by the abdominal press. The force required to fracture the leg of a calf varies with its weight. When traction is applied to the dorsal surface of a limb with an obstetric chain around the pastern, a mean force of 170 kg is required to fracture the leg. The mean force that can be generated by veterinary students is close to 180 kg, with strong individuals able to apply as much as 200 kg of force. A mechanical fetal extractor can apply approximately 400 kg of force while a tractor may apply greater than 5000 kg. The obstetrician must determine if vaginal delivery is likely to be possible without endangering the dam or the fetus. Come along to see how this can be determined.
