title: Restriction of oral intake during labor: whither are we bound?
abstract: In 1946, Dr Curtis Mendelson suggested that aspiration during general anesthesia for delivery was avoidable by restricting oral intake during labor. This suggestion proved influential, and restriction of oral intake in labor became the norm. These limitations may contribute to fear and feelings of intimidation among parturients. Modern obstetrics, especially in the setting of advances in obstetric anesthesia, does not mirror the clinical landscape of Mendelson; hence, one is left to question if his findings remain relevant or if they should inform current recommendations. The use of general anesthesia at time of cesarean delivery has seen a remarkable decline with increased use of effective neuraxial analgesia as the standard of care in modern obstetric anesthesia. While the American College of Obstetricians and Gynecologists now endorses clear liquids during labor, current recommendations continue to suggest that solid food intake should be avoided. Recent evidence from a systematic review involving 3130 women in active labor suggests that oral intake should not be restricted in women at low risk of complications, given there were no identified benefits or harms of a liberal diet. Aspiration and other adverse maternal outcomes may be unrelated to oral intake in labor and as such, qualitative measures such as patient satisfaction should be paramount. It is time to reassess the impact of oral intake restriction during labor given the minimal risk of aspiration during labor in the setting of modern obstetric anesthesia practices.
