(Reuters Health) - Women may be able to eat more than just ice chips during labor without risking complications, according to a new review of previous research.
In fact, women who were allowed to eat before delivery had a slightly shorter labor than those who were restricted to ice chips or sips of water - although the study can’t prove that eating caused deliveries to happen sooner.
“We really don’t know how much if anything people can eat or drink in labor,” said senior author Dr. Vincenzo Berghella, of Thomas Jefferson University in Philadelphia.
Whether women can have more than water or ice chips as they labor to give birth is a common discussion among healthcare providers, he told Reuters Health.
Concerns go back decades, to a 1940s study in which women who delivered under general anesthesia were at risk of inhaling their stomach contents and choking in it, Berghella and colleagues write in Obstetrics and Gynecology.
The use of general anesthesia during delivery is far less common today, but guidelines still recommend against eating solid food during labor, they add.
For the new study, the researchers compiled data from randomized controlled trials that compared the labor outcomes of women who were allowed to eat only ice chips or water and those who were allowed to eat or drink a bit more.
For example, one study allowed women to drink a honey and date syrup. Another study allowed all types of food and drinks. A few others allowed women to drink liquids with carbohydrates.
Overall, the researchers analyzed 10 trials that included 3,982 women in labor. All were only delivering one child - not twins or triplets - and were not at risk for cesarean delivery.
The women with the less restrictive diets were not at increased risk for other complications, including vomiting or choking, during the use of general anesthesia.
And women who were allowed to eat and drink more than the traditional ice chips and water had labors that were shorter, by an average of 16 minutes, compared to women with the more restrictive diets.
“If we’re well hydrated and have adequate carbohydrate in our body, our muscles work better,” said Berghella. A woman’s uterus is largely made of muscle.
The finding is reinforced by another of his studies, which found women who received more fluid than normal delivered faster than other women.
Berghella said it’s still common practice for women with uncomplicated births to be restricted to water or ice chips during labor.
“The evidence from well-done studies is they can have more than that,” he said.
