Effects of Multi-Mechanism Complementary Therapy on Pain and Anxiety During Labor Latency in Primiparous Women.

Objective: Evaluate the efficacy of single and mixed complementary therapies, with different analgesic mechanisms, in relieving pain and anxiety during the late labor period. Design and method: In this study, 145 primiparous women with 2-3 cm dilation of the cervix were randomly assigned to one of five groups: control group (psychological comfort), comprehensive group, aroma group, auricular acupuncture group, and music group. The groups were distributed equally (1:1:1:1 ratio), and pain and anxiety scores were assessed at 30, 60, and 120 minutes post-intervention in each group. Outcomes and measures: Compared to the control group, all intervention groups showed lower pain scores. The comprehensive group had the largest reduction in pain scores at 30, 60, and 120 minutes post-intervention. The auricular point, aroma, and music groups also demonstrated significant reductions in pain scores at different time points. Only the comprehensive group had a statistically significant reduction in anxiety at 30 minutes post-intervention compared to the control group. However, at 60 and 120 minutes post-intervention, all intervention groups showed lower anxiety scores compared to the control group. Conclusion: The optimal effects of each therapy varied in terms of timing and duration. Combination therapy showed a greater effect size than single complementary therapy.
