To evaluate the safety and effectiveness of P-6 acustimulation for the relief of nausea and vomiting associated with early pregnancy.


Forty-one patients were treated with a P-6 acustimulation device at the Division of Maternal-Fetal Medicine, Eastern Virginia Medical School. Pretreatment nausea severity, posttreatment nausea relief and device effectiveness were patient rated using a 1-5 scale. All neonates were evaluated for congenital abnormalities.


Pretreatment nausea severity scores for treated patients averaged 4.2, with most severe and debilitating nausea rated 5. Posttreatment device effectiveness averaged 4.2, with significant or complete relief rated 5. Device ease of use averaged 4.3, with very easy to use rated 5. No congenital abnormalities were found.


Because current pharmacologic treatments for nausea in early pregnancy are not consistent, efficacious or without unwanted side effects or increased teratogenic risks, acustimulation of P-6 in pregnancy may prove to be a significant therapeutic alternative.
