Abstract
OBJECTIVES
We aimed to determine the feasibility of conducting a randomised controlled trial (RCT) on the use of aromatherapy during labour as a care option that could improve maternal and neonatal outcomes.
DESIGN
RCT comparing aromatherapy with standard care during labour.
SETTING
District general maternity unit in Italy.
SAMPLE
Two hundred and fifty-one women randomised to aromatherapy and 262 controls.
METHODS
Participants randomly assigned to administration of selected essential oils during labour by midwives specifically trained in their use and modes of application.
MAIN OUTCOME MEASURES
Intrapartum outcomes were the following: operative delivery, spontaneous delivery, first- and second-stage augmentation, pharmacological pain relief, artificial rupture of membranes, vaginal examinations, episiotomy, labour length, neonatal wellbeing (Apgar scores) and transfer to neonatal intensive care unit (NICU).
RESULTS
There were no significant differences for the following outcomes: caesarean section (relative risk [RR] 0.99, 95% CI: 0.70-1.41), ventouse (RR 1.5, 95% CI: 0.31-7.62), Kristeller manoeuvre (RR 0.97, 95% CI: 0.64-1.48), spontaneous vaginal delivery (RR 0.99, 95% CI: 0.75-1.3), first-stage augmentation (RR 1.01, 95% CI: 0.83-1.4) and second-stage augmentation (RR 1.18, 95% CI: 0.82-1.7). Significantly more babies born to control participants were transferred to NICU, 0 versus 6 (2%), P = 0.017. Pain perception was reduced in aromatherapy group for nulliparae. The study, however, was underpowered.
CONCLUSION
This study demonstrated that it is possible to undertake an RCT using aromatherapy as an intervention to examine a range of intrapartum outcomes, and it provides useful information for future sample size calculations.
