A new study presented at the annual meeting of the American Society of Anesthesiologists suggested light meals during labor may be safe for most women. Ordinarily we would like to restrict intake to clear liquids nothing at all depending on the risk level of the woman. The main concern here is the risk of aspiration which means inhaling food particles from the stomach into the respiratory tract. Pregnant women are at increased risk for aspiration compared to non-pregnant women due to the pressure from the baby and the relaxation of the esophageal muscles. Moreover, women are often nauseous during labor, increasing risk. The highest concern comes if the patient needs to go to cesarean section. In this instance she needs to be on her back with only a slight tilt, and this increases the risk of aspiration even further. It is unfortunate that the lay reporting makes it sound like we fear that women might aspirate during normal labor. Our concern is mostly having to do with the chance that they will go to cesarean section on a full stomach.
