A pregnant woman is considered to always have a “full stomach” due to delayed gastric emptying and incompetent lower esophageal sphincter. Thus, pregnant women are at increased risk for aspiration (13;14). Therefore, prophylactic measures to prevent aspiration should be used, particularly during the third trimester. A woman with multiple gestation is at increased risk for aspiration in the mid-second trimester because of the large uterus. Maintaining a semi-seated position and avoiding excessive sedation are required to prevent aspiration. Conscious sedation should be the last possible alternative in the third trimester. These women may be best treated with general anesthesia in.
