Higher Rate of IV Fluids Associated with Fewer Cesarean Sections

Fewer cesarean sections are possible in women who are administered with an increased rate of IV fluids, reveals study.

Pregnancy is a joy, but labor is an intensely strenuous activity. The uterine muscles need to contract every few minutes to reposition the baby through the pelvis and down the birth canal.

Even a slightly reduced level of dehydration can //seriously compromise the physiological functions. A research team from the Thomas Jefferson University found that higher rate of IV fluids not only decreased the c-section rates but also reduced the length of labor by an hour. It was also found to shorten the pushing phase.

‘IV fluids were found to help women maintain hydration at appropriate levels and reduce the likelihood of cesarean section.’

The study results were published in Acta Obstetrica et Gynecologica Scandinavica.

"The results are compelling and strongly argue for a change in practice," says Vincenzo Berghella, M.D., the Director of Maternal Fetal Medicine and Professor in the Department of Obstetrics and Gynecology at the Sidney Kimmel Medical College at Thomas Jefferson University. "We have already begun changing practice at Jefferson to give women more fluids in labor, to allow them to have the best chance of delivering vaginally."

Dr. Berghella and colleagues compiled data from seven small clinical trials that collectively included a total of 1,215 women. Of those, about half (or 593 women) received IV fluids at a rate of 250 milliliters per hour, and the other half (622 women) received fluids at the lower rate of 125 milliliters per hour. General practice in the United States is to administer IV fluids at 125 milliliters per hour during labor.

With the data pooled, the researchers could see a clear difference in outcomes for women in the two groups. Women getting the faster fluid rate (250 milliliters per hour) were less likely to get a cesarean section. The higher fluid rate also reduced the overall time of labor by an average of 64 minutes, and shortened the pushing phase by nearly 3 minutes, on average.

"We've known that it's important for women to stay well hydrated during pregnancy and labor. This study suggests that IV fluids could help women maintain hydration at appropriate levels, reduce the likelihood of c-section, and decrease length of labor," says Dr. Berghella. "Recently, we also showed that letting women eat more liberally in labor, especially in early labor, has benefits including shorter labor, and no identifiable risks."

Children Born by Cesarean Section may Become Overweight
Compared to vaginally-delivered children, Cesarean-delivered children had 40 percent greater odds of becoming overweight or obese in childhood.

Today, approximately one in three births in the United States occurs via c-section, despite an increased attention by national and international obstetric societies on safely reducing the practice. This study and others are providing evidence for changes in obstetric practice that could help safely reduce c-section rates. Drs. Ehsanipoor, Saccone, Seligman, Pierce-Williams, and Ciardulli were the co-investigators with Dr Berghella.

Study Finds Lower Chloride Use in IV Fluids for ICU Patients May Lower Risk of Kidney Injury
Restricting the amount of chloride in intravenous fluids administered to critically ill patients in an intensive care unit was found to lower risk of acute kidney injury.
