Peanut ball shortens active labor by 90 minutes; no effect on pain or anxiety
Background
Managing labor pain and anxiety remains a critical challenge in obstetrics, often requiring pharmacological interventions with potential side effects. Non-pharmacological methods offer appealing alternatives, yet robust evidence, particularly from public hospital settings in regions like Honduras, is scarce. The peanut ball, a simple tool, has shown promise in some contexts for facilitating labor progression and comfort, but its efficacy in reducing specific outcomes like pain and anxiety, and its impact on labor duration, needs further rigorous evaluation in diverse populations.
Study Design
A single-blind, parallel-group randomized clinical trial was conducted in Honduras with 163 nulliparous women in active labor (cervical dilation ≥4 cm). Participants were assigned to an intervention group (n=83) receiving standard care plus intermittent peanut ball use, or a control group (n=80) receiving standard care alone. Primary outcomes were pain and anxiety, measured using Visual Analog Scales. Secondary outcomes included active labor duration and oxytocin use. The study performed pre-planned subgroup analyses (no oxytocin) and adjusted analyses.
Results
No significant differences were observed between groups for primary outcomes: pain scores (p=0.45) and anxiety levels (p=0.62) remained similar, as did overall maternal well-being. However, a notable effect was found on labor duration. The active phase was significantly shorter in the intervention group, with a mean duration of 162 minutes (SD=78), compared to 252 minutes (SD=138) in the control group. This represented a mean difference of -90.0 minutes (95% CI: -172.37-7.7; p=0.03). This reduction in active labor duration persisted in the subgroup of women who did not receive oxytocin (p=0.012) and after statistical adjustment. Interestingly, oxytocin use was higher in the intervention group (67.5% vs 38.8%; risk ratio, RR=1.74; 95% CI: 1.25-2.42; p=0.001). Cesarean birth rates and other maternal outcomes were comparable between groups.
Active labor duration was significantly shorter in the intervention group, averaging 162 minutes (SD=78) compared to 252 minutes (SD=138) in controls, a mean difference of -90.0 minutes (p=0.03).
Key Findings
- Intermittent peanut ball use did not significantly reduce labor pain (p=0.45).
- Anxiety levels were not significantly different between groups with peanut ball use (p=0.62).
- Active labor duration was 90 minutes shorter in the peanut ball group (p=0.03).
- The effect on labor duration persisted in the subgroup without oxytocin (p=0.012).
- Oxytocin use was higher in the peanut ball group (67.5% vs 38.8%; RR=1.74; p=0.001).
Why It Matters
This study provides evidence that intermittent peanut ball use can significantly shorten the active phase of labor, potentially reducing the overall time women spend in delivery. While it doesn't directly alleviate pain or anxiety, its impact on labor progression could be valuable for both patients and healthcare providers, potentially leading to fewer interventions related to prolonged labor. Clinicians might consider incorporating the peanut ball as a tool to support labor progression, especially in settings where reducing labor duration is a priority. However, it's crucial to integrate it with other pain and anxiety management strategies, as it does not address those aspects directly. The observed increase in oxytocin use in the intervention group warrants further investigation to understand its implications for labor management protocols.
