text: During a C-section the time from the inciscion into the uterus and the baby coming out is within a minute or 2. The doctor will pull the head out and then they will push on your belly on the babies tush to get the rest to come out;  unless the baby is lying on its side then the doctor has to turn it a little and it may take a little longer.  During a normal C-section there is no chance for brain damage unless there is a break in the circulation of blood running thru the cord to the baby.  In an ultimate emergency like a prolasped cord ( when the cord comes out before the babies head and pinching off the blood flow)  where i have worked we have the baby out in a matter of minutes 5-10, and someone has their hand in the vagine holding the baby's head off the cord until the baby is pulled out by C-section.  So.. in most normal C-sections there is little risk for brain damage.
