Effect of Lamaze breathing method on negative emotion and delivery outcome of maternal

Objective To investigate the effect of lamaze breathing method with unprotected delivery technology on maternal negative emotions and birth outcomes,thus to provide effective reference to the improvement of the quality of delivery for obstetrics and high quality nursing service. Methods A total of 460 cases of low-risk primiparas who set up a cord of medical care and delivered in our hospital were randomly divided into control group and observation group with 230 cases in each group.While the control group received routine prenatal care and pregnancy education,using the technology of traditional protection of perineum childbirth,observation group voluntarily accepted lamaze breathing since the 28th weeks and insisted on learning practice every day until the parturient with unprotected perineum delivery technology.Self rating Anxiety Scale(SAS) and self rating Depression Scale(SDS) were used to compare between the two groups of primiparas' negative emotional status and observation of the two groups were made to compare the perineal laceration,the second stage of labor time,postpartum hemorrhage and neonatal weight asphyxia. Results The primiparas in observation group got (33.20±9.53) SAS score and (31.15±6.44) SDS score within 12 h before delivery which were lower than those in the control group,(64.38±5.50) SAS score and (61.89±5.09) SDS score respectively,with statistical significance(t=42.96,56.79,P<0.001).In the observation group,the perineal integrity rate was 12.17%,second degree perineal laceration incidence was 25.65%(59/23).In the control group perineal integrity rate was 2.61%,second degree perineal laceration incidence was 39.13%(90/230).The perineal integrity rate and second degree perineal complete laceration in the observation group was significantly lower than those in the control group(χ²=14.01,9.54,P<0.05).Postpartum hemorrhage amount in the observation group was (225.12±46.12)ml lower than that(248.20±50.28)ml in the control group,and the difference was statistically significant(t=5.13,P<0.05);The observation group had 4 cases of neonatal asphyxia(1.74%),less than that 19(8.26%) in the control group,and the difference was statistically significant(χ²=10.30,P<0.05). Conclusion The lamaze breathing method in the low-risk parturient with unprotected perineum delivery of primipara technique can improve negative emotions,reduce perineal injury,reduce postpartum hemorrhage and neonatal asphyxia,and promote natural childbirth.
