Abstract

Background: Pregnancy induces physiological changes, commonly marked by nausea and vomiting in the first trimester, posing risks for both mother and baby. This study evaluates the effects of auriculotherapy on nausea and vomiting during the first trimester of pregnancy.

Materials and Methods: A randomized clinical trial was conducted in two primary health care centers with 56 Brazilian pregnant women who reported nausea or vomiting in the first trimester. The participants were divided into an intervention group (auriculotherapy with seeds) and a placebo group (sham auriculotherapy). The intervention was divided into three moments: pre-intervention with assessment of nausea and vomiting and application of questionnaires, and two follow-ups conducted on the fourth and seventh day of the intervention, with reassessment of nausea and vomiting.

Results: Both groups experienced a decrease in nausea and vomiting over time, with no statistically significant differences between groups in the within-group analyses at various time points. The intervention group had a greater reduction in symptoms. Within the intervention group, symptoms were more common among ferrous sulfate users and those without reported dietary disturbances. In addition, a higher incidence of nausea and vomiting was associated with the use of analgesics, morning snacks, and low intake of protein, vegetables, and fruits.

Conclusions: The intervention did not affect the between-group differences in the incidence of nausea and vomiting and vomiting effort in the first trimester of pregnancy. However, a greater reduction was observed in the intervention group.
