Aim: Perinatal negative emotions are common in parturient women, but the problems are often ignored. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) that investigated the effectiveness of aromatherapy for intrapartum anxiety (IPA) and postpartum emotional symptoms (PES).
Methods: We searched PubMed, Embase, Cochrane library, and ClinicalTrials.gov to identify suitable RCTs for analysis, and the study was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.
Results: Nine RCTs were included. The meta-analysis showed aromatherapy reduced IPA during the early to active phase (standardized mean difference [SMD]: -1.56 [-2.55, -0.61]) and during the transition phase (SMD: -3.30 [-4.97, -1.63]) when compared with controls. For the postpartum period, the meta-analyses showed a reduction of postpartum depression (PPD) at week 2 (SMD: -0.43 [-0.82, -0.03]), and a non-significant trend toward the reduction of PPD at weeks 4-6 (SMD: -0.70 [-1.40, 0.01]).
Conclusion: Our study found some evidence supporting the effectiveness of aromatherapy in reducing intrapartum anxiety and PES. We recommend the optional use of aromatherapy for intrapartum and postpartum care.
