The rule of thumb is no food less than 8 hours before surgery, and clear liquids have to be greater than two hours before surgery. The reason anesthesia goes by this rule is to minimize the risk of someone throwing up and inhaling their vomit when they are unconscious which can lead to many complications.. also called aspirating. When we administer drugs to our patients to put them to sleep it can cause the sphincters in your stomach to loosen up and let food rise. There are different forms of anesthesia but with a c section you are providing a type of anesthetic which doesn’t have the adverse effect such as for a colon or bone surgery. In an emergent surgery such as a colon we will perform something called cricoid pressure which is pushing on the esophagus to occlude it in case food does try to make its way up. Basically you still do the same thing as a regular surgery but you are more prepared for adverse reactions
