Pmn-20: A Randomized Clinical Trial of The Efficacy of Acupressure on Nausea and Vomiting of Pregnancy

Background: Considering nausea and vomiting are a common complaint of pregnancy. Most non-medication therapy and complementary and alternative medicine were preferred to reduce it in recent years. The aim of our study is to determine the effect of acupressure (on point KID21) on nausea and vomiting of pregnancy. Materials and Methods : This single blind clinical trial study was performed on 80 women with nausea and vomiting in the first trimester of pregnancy. Women were randomly divided to two groups; intervention group with the acupressure on KID21 point and the placebo group with pressure on sham acupressure for 20 minutes per day in four consecutive days. The intensity of nausea was assessed by visual analogue scale (VAS) and vomiting frequency was evaluated by counting during these four days. The results compared with each other by Chisquare, t tests, Mann-Whitney, Friedman and Sign-rank test. Results: The intensity of nausea between intervention and placebo groups was shown statistically significant differences on the fourth day (p<0.001 U=228.5) and also the intensity of vomiting on the fourth day demonstrated significant difference between two groups (p<0.001, U=380). The intensity of nausea and vomiting in the intervention group was less significantly (p<0.05). Conclusion: Acupressure with pressure on point KID21 is more effective than sham acupressure in reduction of nausea and vomiting in pregnancy, so it can be purposed to diminish intensity of pregnancy nausea and vomiting.
