[1] Most commonly, a baby is delivered by making a transverse incision in the lower uterine segment, above the attachment of the urinary bladder to the uterus.

[3] Although the incision is made using a sharp scalpel, care must be taken not to injure the foetus, especially if the membranes are ruptured, or in emergencies like abruption.

While using the scissors, the surgeon should ensure that a finger is placed underneath the uterus so that the foetus in protected from unintentional injury.

Kerr published the results in 1920, proposing that this method would cause less damage to the vascularized areas of uterus than the classical operation.

He claimed that it was better than the longitudinal uterine incision in terms of chances for scar rupture and injury to vessels.
