peanut ball

Also: peanut-shaped ball, labor peanut ball

A peanut-shaped inflatable ball used in labor to support positions that may help the baby move lower. The evidence for its effect is limited.

In plain words

A peanut ball is a large inflatable cushion shaped like a peanut. It is placed between the mother's legs while she sits or leans on a bed or chair. The shape allows the legs to open wider than they would in a usual position. Some care teams use it to support positions that may help the baby move lower and turn. It can also make resting in labor easier for some mothers. The evidence for its effect is limited, and results from small studies are mixed. Whether one is available depends on the birth setting.

The deeper version

The peanut ball is an asymmetric inflatable used to widen the pelvic outlet and encourage fetal descent and rotation in the , often in combination with upright or semi-recumbent positions. Evidence for its effect is limited to small trials and observational work. The Cochrane review of maternal positions and mobility in the first stage (Lawrence et al., 2013) found that upright positions were associated with a shorter first stage of labor, with low to moderate quality of evidence across trials. Use with analgesia is possible, and nursing protocols specify repositioning and bladder management to maintain pelvic mobility.
