Abstract:Objective To investigate the effect of delivery ball combined with free body position assisted delivery on the delivery process, labor pain, and psychological state of primiparous women.Methods The study was conducted on 85 maternal data samples, with a collection time limit of January 2022 to January 2023, and ensuring that all selected mothers were primiparous. After enrollment, due to research needs, two groups need to be set up, and the mothers were divided into two groups using the random number table method as the grouping principle. One group of 42 cases was determined as the control group with traditional or semi lying positions; another group of 43 cases were designated as the observation group with delivery balls in combination with free body position. Both groups were observed until 7 days postpartum. Compare the 2 hour postpartum bleeding volume and duration of labor, mental health score and pain level score, quality of life score, self-efficacy score, maternal and neonatal outcomes between the two groups.Results The postpartum bleeding volume of the observation group was at a lower level within 2 hours, while the first, second, third, and total stages of labor were shorter in the observation group. After intervention, the SAS, SDS, and VAS scores of the two groups of postpartum women showed a decreasing trend compared with before intervention, and the observation group was at a lower level. After intervention, the scores of subjective symptoms, psychological state, physiological state, daily life state, and social activity state of the postpartum women in the observation group were all at a higher level. After intervention, the OE-16, EE-16, and total scores of the two groups of postpartum women showed an upward trend compared with before intervention, and the observation group was at a higher level. The total incidence of cesarean section, postpartum hemorrhage, postpartum depression and the total incidence of neonatal fetal distress, neonatal asphyxia, and meconium aspiration in the observation group after intervention was at a lower level, P<0.05, indicating a significant difference in the calculated data.Conclusion Delivery ball combined with free position assisted delivery can shorten the delivery process of primiparous women, reduce postpartum bleeding, improve their psychological state, reduce pain level, improve their quality of life and self-efficacy, and improve maternal and neonatal outcomes.
