Effect of acupressure on nausea and vomiting during pregnancy. A randomized, placebo-controlled, pilot study.

2001 Sep;46(9):835-9.

Abstract

OBJECTIVE:

To compare the antiemetic effect of acupressure at the Neiguan point (P6) in a group of healthy women with normal pregnancy and nausea and vomiting during pregnancy (NVP) with a similar group receiving acupressure at a placebo point and another, similar group not receiving any treatment.

STUDY DESIGN:

A randomized, placebo-controlled, pilot study involving 60 women.

RESULTS:

It is possible to reduce NVP significantly with acupressure at P6 as compared to acupressure at a placebo point or no treatment at all in healthy women with normal pregnancies. Relief from nausea appeared one day after starting treatment in both the P6 and placebo groups but lasted for only six days in the placebo group. The P6 group, however, experienced significantly less nausea after 14 days as compared to the other two groups.

CONCLUSION:

This study involved 60 healthy women with normal pregnancy and suffering from NVP. According to the results, in healthy women with normal pregnancy it is possible to reduce NVP significantly at P6 as compared to acupressure at a placebo point and to no treatment.

2005 Jun;35(3):593-601.

Abstract

PURPOSE:

The purpose of this study was to determine the effects of Nei-Guan(P6) acupressure on nausea and vomiting in pregnant women having hyperemesis gravidarum.

METHOD:

The research design was a randomized control-group pretest-posttest repeated measure design with counter balancing. For the experimental treatment, P6 acupressure was carried out for ten minutes. Data was collected from April 1, 2003 to April 30, 2004. The participants were 66 patients admitted with hyperemesis gravidarum. They were divided into three groups, a P6 acupressure group, placebo point group and a control group.

RESULT:

Hyperemesis gravidarum patients who received P6 acupressure during admission experienced much less nausea and vomiting than the placebo acupressure and control group (F=8.259, p=.001).

CONCLUSION:

Nei-Guan(P6) acupressure is considered an effective intervention for reducing nausea and vomiting in pregnant women having hyperemesis gravidarum. Further more Nei-Guan(P6) acupressure maybe used as an independent nursing intervention method for pregnant women with severe nausea and vomiting.
