A peanut ball is an inflatable, hourglass-shaped device used during labor to support various positions. It helps laboring individuals maintain an open pelvic alignment, particularly when mobility is limited.
Understanding the Peanut Ball
A peanut ball is distinct from a traditional round birthing ball due to its unique hourglass shape, with two larger ends and a narrower middle section. Made from durable, inflatable material, these balls come in various sizes to accommodate different heights. This design allows it to be placed between the legs, supporting and separating them even when lying down.
Mechanism of Action During Labor
The peanut ball facilitates changes in pelvic dimensions. When positioned between the legs, particularly in side-lying or semi-reclined positions, it helps open the pelvis, creating more space for the baby to descend. The ball also encourages optimal fetal positioning by promoting rotation and flexion. This mechanical advantage is especially beneficial for individuals with an epidural or fatigue, as it allows passive positional changes while remaining in bed.
Peanut Ball and Labor Onset: Clarifying the Role
A peanut ball does not medically induce labor or initiate contractions. Its role focuses on enhancing the natural progression of labor once contractions have begun. The peanut ball assists by optimizing pelvic space and fetal alignment, potentially making existing labor more efficient. It serves as a supportive tool to facilitate the birthing process rather than to start it.
Impact on Labor Progression
Using a peanut ball can positively influence labor duration and outcomes. Studies suggest it shortens the first stage of labor by 29 to 90 minutes, and the second stage by 11 to 23 minutes. The peanut ball has also been associated with reduced medical interventions, including lower cesarean section rates. One study showed a significant decrease in C-section rates, with 10% for peanut ball users compared to 21% for non-users with epidurals. It may also contribute to increased maternal comfort and satisfaction during labor.
Practical Application of the Peanut Ball
The peanut ball can be used in several positions. A common method involves lying on one’s side with the ball between the knees, which helps open the top of the pelvis. Another effective position is semi-reclined, with one leg draped over the ball while the other remains bent, promoting continued labor progress. For individuals experiencing back labor, an all-fours position with ball support can be helpful. It is recommended to use the peanut ball under the guidance of healthcare professionals, who can advise on the most suitable positions and ball size, with regular changes every 20 to 60 minutes to maintain circulation and promote labor progression.
