A Comparative Study Of Lavender Inhalation With Epidural Analgesia On Reducing Labor Pain And Intrapartum Outcomes In Primiparas

ObjectiveIn this study,we compared the effects of lavender inhalation,epidural analgesia,and lavender inhalation combined with epidural analgesia on parturition,and to understand the impact of different methods on the hospitalization of primiparas.To evaluate the effects and analyse the mechanism of different methods on primiparas.To explore the intrapartum outcomes of primiparas under different methods and analyze their causes,and to provide evidence for clinical analgesic delivery.MethodsAccording to inclusion criteria,exclusion criteria and rejection criteria,a total of 254 in-patient primiparas in Longgang District Maternal and Child Health Hospital in Shenzhen were selected in this study by cluster sampling from July to December 2018.When the uterine orifice was expanded by 3 cm,they were divided into the control group?62 cases?,the inhalation group?60 cases?,the epidural group?68 cases?,and the combined group?64 cases?according to their willings.The control group was given routine delivery care.On the basis of conventional care,when the uterine orifice was expanded by 3 cm,the inhalation group began sniffing lavender intermittently while the epidural group was given epidural analgesia,and the combined group was given lavender inhalation combined with epidural analgesia.A total of 254 primiparas were investigated by using the General Information Questionnaire,Symptom Checklist?SCL-90?,Simplified Chinese Version of Self-efficacy Questionnaire for Delivery?CBSEI-32?,and Digital Rating Scale?NRS?before they were in labor.At the time of delivery,the Digital Rating Scale?NRS?was used to assess the pain scores of the maternal uterine expansion at 4-5cm,6-7cm,and 8-10cm,and vital signs and duration of labor were measured.Postpartum records include delivery outcomes,lactation,neonatal outcomes,and hospitalization.SPSS 26.0 was used for statistical analysis.Measurement data conforming to the normal distribution were expressed as mean±standard deviation,and a one-way analysis of variance was used for comparison.LSD or Games-Howell method was used for comparison between groups.Measurement data that did not conform to the normal distribution were expressed as M(P₂₅,P₇₅),and non-parametric Kruskal-Wallis test was used for comparison.Comparison between groups used All pairwise method.Counting data was expressed by the number of cases and percentage?%?,and chi-square test was used for comparison.Bonferroni method was used for comparison between groups.The test level?=0.05,P<0.05 was considered statistically significant.Results?1?The NRS score from high to low at 4-5 cm cervix dilatation was as follows:the control group,the inhalation group,the epidural group,and the combined group.Pairwise comparison showed that there was no statistical difference in the NRS score between the epidural group and the combined group,and there were statistical differences in the NRS scores between the control group and the other groups?P<0.05?.The NRS score from high to low at 6-7 cm cervix dilatation was as follows:the control group,the epidural group,the inhalation group,and the combined group.The difference was statistically significant?P<0.05?.Pairwise comparison showed that there was no statistical difference in the NRS score between the inhalation group and the epidural group,and there were statistical differences in the NRS scores between the control group and the other groups?P<0.05?.There was no significant difference in the NRS scores between the four groups at 8-10 cm cervix dilatation?P>0.05?.?2?The body temperature,the first stage of labor,the total stage of labor,the oxytocin use rate,the rate of amniotic fluid turbidity,and the delayed incidence rate of neonatal physiological jaundice regression time in the epidural group and combined group were significantly higher than those in the control group and inhalation group,the difference was statistically significant?P<0.05?.?3?The comfort scores of the four groups of primiparas during hospitalization were the highest in the combined group and the lowest in the control group.There was no significant difference in the scores of the lavender inhalation group and the epidural group?P>0.05?.The hospitalization days and hospitalization costs of the epidural group and the combined group were significantly more than those of the control group and the inhalation group,and the differences were statistically significant?P<0.05?.Conclusion?1?The effect of epidural analgesia was fast and obvious,but the duration was short,and it would have some adverse effects on maternal and newborns.Although epidural analgesia could improve the comfort of delivery,the use of drugs increased the cost of hospitalization accordingly.?2?Lavender inhalation had a slow analgesic effect,but it last a long time and had no adverse effects on maternal and newborns.Without increasing the cost of hospitalization,the comfort of delivery was improved.?3?Although lavender inhalation combined with epidural analgesia would increase the cost of hospitalization,the synergistic effect between them can meet the need of comfort in labor better.
