Birthing balls to decrease labor pain and peanut balls to decrease length of labor: what is the evidence?

Birthing balls and peanut balls have been used for decades by nurses and midwives as a nonpharmacologic adjunct to labor management based on anecdotal evidence. This article aimed to review the evidence regarding their safety and efficacy based on randomized controlled trials. Birthing balls are round exercise balls that a laboring individual can use for sitting, rocking, and pelvic rotation. The use of the birthing balls has been thought to increase maternal comfort and mimic upright positioning to widen the pelvic outlet for those laboring without an epidural. A recent meta-analysis showed that the use of the birthing ball in labor significantly reduces maternal pain in labor by 1.7 points on a standard visual analog scale of 1 to 10 (mean difference, -1.70 points; 95% confidence interval, -2.20 to -1.20). The use of the birthing ball does not significantly affect the mode of delivery or the rate of other obstetrical complications. This suggests that its use is safe and can offer subjective improvement in maternal pain experienced during labor. The peanut ball is a peanut-shaped plastic ball placed between the knees of a person laboring in the lateral recumbent position, a position common in those laboring with an epidural. Traditionally, its use has been thought to allow for bent-knee positioning that can mimic a squatting position and facilitate frequent and optimal position changes during labor. Data regarding the effects of the peanut ball are mixed. A recent systematic review and meta-analysis found that the use of the peanut ball compared with no peanut ball is associated with a significantly decreased first stage of labor (mean difference, -87.42 minutes; 95% confidence interval, -94.49 to -80.34) and an 11% higher relative risk of vaginal delivery (relative risk, 1.11; 95% confidence interval, 1.02-1.22; n=669). The use of the peanut ball is not associated with increased incidences of obstetrical complications. As such, it is reasonable to offer to individuals in labor. There has been no reported risk of the use of either the birthing ball or the peanut ball. As such, both interventions can be offered to individuals in labor as an adjunct to labor management techniques based on moderate quality evidence.

Improving labour progression among women with epidural anesthesia following use of a birthing ball: a review of recent literature

Epidural anaesthesia is an effective form of pain relief during vaginal deliveries. However, neuraxial anaesthesia may slow the progression of labour. The assumption that epidurals lead to increased caesarean sections is also a topic of current debate. A holistic approach with the use of a birthing ball has been advocated as a potential modality to decrease labouring times and, therefore, reduce progression to caesarean section. Birthing balls aim to increase pelvic outlet opening, which facilitates labouring. Our aim is to review recent literature pertaining to birthing balls and their role in improving quality and outcomes of vaginal deliveries in patients with epidurals.IMPACT STATEMENTWhat is already known on the subject? Epidural anaesthesia may slow the progression of labour. It has been hypothesised that slowing progression of labour is associated with increased rates of vacuum and forceps delivery. Most common clinical indication for caesarean section is failure to progress during labour. Birthing Balls have been shown to quicken the progression of labour, theoretically reducing caesarean sections with those with epidurals.What do the results of the study add? Several studies have demonstrated a reduced duration of first and second stage of labour among women with epidural anaesthesia, but the existing literature is limited, and interpretation of results may be restricted by generalizability and inherent study biases. The objective of this article is to review existing literature and highlight the potential clinical utility of birthing balls in current obstetric practice.What are the implications of these findings for clinical practice and further research? Use of birthing balls has been advocated to decrease labouring time and therefore reduce progression to caesarean section. Larger studies or meta-analysis would be required to confirm potential benefits of birthing ball use.
