Ensayo clínico controlado y aleatorizado para determinar los efectos del uso de pelotas de parto durante el trabajo de parto / Randomised controlled clinical trial to determine the effects of the use of birth balls during labour

Objetivo. Determinar los efectos del uso de la pelota de parto (PdP) durante el trabajo de parto en relación al tiempo de dilatación y expulsivo, la integridad perineal, la percepción de la intensidad del dolor y la seguridad. Método. Ensayo clínico controlado y aleatorizado. Participantes: nulíparas de 18 a 35 años, bajo riesgo, a término. Intervención: realización de movimientos sentadas sobre PdP durante el parto. Variables resultado: tiempo de dilatación y expulsivo; integridad perineal; percepción del dolor, recuerdo del dolor en el puerperio y pre-post intervención; tipo de parto; motivo de distocia; Apgar; ingreso en UCI neonatal. Análisis: comparación de grupos: t-Student para variables contínuas y Ji-cuadrado para categóricas. Significación p≤0,05. Resultados: 58 participantes (34 grupo experimental y 24 grupo control). El tiempo de dilatación y expulsivo, y la integridad perineal fue similar entre grupos. A los 4cm el grupo experimental refirió menos dolor que el grupo control; 6,9 puntos vs 8,2 (p=0,039). La diferencia en la percepción del dolor recordada en el puerperio inmediato fue de 1,48 puntos mayor en el grupo control (p=0,003). La medición del dolor en el grupo experimental antes del uso de la PdP fue de 7,45 puntos y tras la intervención de 6,07 puntos (p<0,001). En las variables relacionadas con la seguridad no hubo diferencias entre los grupos. Conclusión. El uso de pelotas de parto disminuye la percepción del dolor de parto y es segura (AU)

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 4cm. 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 (AU)
