Background:
Postpartum pain contributes to increased irritability and excessive stress in the mother and consequently may inhibit successful breastfeeding, reduce a mother's ability to take care of her baby, and cause an imperfect mother-baby interaction. Evidence suggests the positive effect of ginger on reduction in uterus-associated pain. The objective of this study is to investigate the effect of ginger capsules on postpartum pain.
Materials And Methods:
The present double-blinded, randomized, placebo-controlled trial was conducted in Mahdiyeh Educational Hospital, Tehran. One hundred and twenty-eight mothers having moderate-to-severe pain following vaginal delivery were included. The participants were divided into two groups (A and B). Interventions were performed every 8 h in 24 h. In the first intervention (2 h after the delivery), Group A received 500 mg of placebo capsules (containing chickpea flour) and Group B received 500 mg of Zintoma (ginger rhizome) capsules. In the second and third interventions, Group A received 250 mg placebo capsules and Group B received 250 mg Zintoma capsules. All participants received 250 mg capsules of mefenamic acid in each intervention in addition to ginger or placebo capsules. The pain severity was measured before and half an hour, an hour, and 2 h after each intervention. Statistical analysis was performed using the SPSS software version. 22. The Chi-square, Fisher's, and t tests and the GEE model were applied to assess the pain severity.
Results:
The average pain severity was not statistically significant between the groups in the beginning of the intervention (P = 0.623). The mean score of pain significantly decreased within the duration of intervention in both groups (P < 0.001); however, the pain severity was significantly lower in the intervention group as compared to the control group at any point after the intervention (P = 0.006).
Conclusion:
Ginger can be used as an effective remedy for postpartum pain relief.
