Objective:
To determine the effects of using birth balls (BB) during the first and second stage of labour, perineal integrity, perception of pain intensity, and safety.
Method:
Randomised controlled trial.
Participants:
18 to 35 years, nulliparous, low-risk, at term.
Intervention:
Performing movements sitting on a BB during obstetric labour.
Main Outcomes:
Duration of first and second labour stages; perineal integrity; pain perception during the postpartum period and pre-post intervention, type of delivery, cause of dystocia, Apgar, neonatal ICU admission.
Analysis:
Comparison of groups: Student-t for continuous variables and chi-squared test for categorical ones. Significance if P ≤.05.
Results:
A total of 58 patients (34 experimental and 24 controls) were included. Times of first and second stage, and perineal integrity were similar between groups. At 4 cm. the experimental group referred less pain than the control group, 6.9 points vs 8.2 (P=.039). Difference in the perception of pain in the immediate postpartum period was 1.48 points higher in the control group (P=.003). The measurement of pain in the experimental group before the use of the BB was of 7.45 points, and after the intervention of 6.07 points (P<.001). In There were no differences between groups as regards safety-related variables.
Conclusion:
The use of a Birth Ball decreases obstetric labour pain perception and is safe.
