Peanut Ball for promoting progress in labour

Sounds a very interesting piece of equipment. We shall do some more investigation regarding the peanut ball because it appears a good addition to the kit. 


"Most experienced peanut ball users recommend either the 45 cm or 55 cm sized peanut ball. The size is measured from the floor to the tallest point on one of the larger ends. Because it will be used between the legs to open up the pelvic outlet, you don’t want it to be as large as the balls that are used for sitting and swaying. As I learned about the peanut ball, I found that many moms who did not like the peanut ball in labor felt it was too big. For this reason, I chose to purchase and use the 45 cm sized ball, which is the size used in the photos that accompany this article.
The peanut ball is most commonly used when mom needs to remain in the bed, whether because of epidural use, complications, or simply because mom is exhausted. There are two main ways in which peanut balls are used, with plenty of room for variation. The first is with mom in a semi reclined position, one leg over the ball, one leg to the side of the ball. The ball is pushed as close to mom’s hips as is comfortable. As the ball can have a tendency to slide away from the mom, a rolled up towel can be used to hold it in place. This position seems to be most commonly used to promote dilation and descent with a well-positioned baby.
The second common use is with mom in a side-lying or semi-prone position, with the peanut ball being used to lift the upper leg and open the pelvic outlet. The ball can be angled so that the leg hooks around the narrower part, or aligned with both mom’s knee and ankle resting on the ball. Mom’s comfort level is key to knowing the right placement. Most women who used this position used it to help rotate a posterior baby to a more favorable position for delivery."



The Research
There is not much research out there on the use of the peanut ball. In my search, I found one study, presented as a poster presentation at the 2011 AWHONN Convention. Tussey and Botsois (2011) randomized 200 women (uncomplicated labor with an epidural) into two groups. One group used the peanut ball in either the semi Fowler’s position (bottom photos) or the sidelying position (top photos), switching sides every 1-2 hours. The sample size was small, but the results were very promising. The first stage of labor was shorter by an average of 90 minutes, and second stage was roughly half as long (43.5 min in the control group, 21.3 min in the peanut ball group). The use of vacuum and forceps was also lower in the peanut ball group. There were no serious adverse events reported in the study. This looks very promising, and I will be watching for more studies on the peanut ball in future years.
