Comparative study of transcutaneous electrical nerve stimulation, the aromatherapy of Lavandula and physiologic delivery without medication on the neonatal and maternal outcome of patients.

Objectives: The complications of normal vaginal delivery (NVD) are one of the issues that researchers have been discussing today and various ways to reduce these outcomes have been presented. In this study, we aimed to compare the effect of Transcutaneous Electrical Nerve Stimulation (TENS), the aromatherapy of Lavandula and physiologic delivery without medication on NVD outcomes.

Methods: This randomized clinical trial was conducted on 150 women that were candidates of NVD. The information related had been registered in the Iranian clinical trial registration system with the code IRCT20210501051151N1 (https://www.irct.ir/trial/56014). Patients were divided into three groups of Lavandula, TENS, and physiologic delivery. Postpartum pain, maternal and neonatal outcomes, and labor duration were compared in groups.

Results: Labor pain was significantly less in TENS and Lavandula than in the physiologic group, respectively (P<0.001). There was no significant difference between the groups in terms of labor duration and maternal and fetal outcomes.

Conclusion: The use of TENS and Lavandula aromatherapy are useful methods for reducing pain in patients undergoing NVD, but using TENS method is better than Lavandula method, and on the other hand, there are no differences between groups as maternal and neonatal complications.
