and Vomiting Definition
Nausea is the sensation of being about to vomit. Vomiting, or emesis, is the
expelling of undigested food through the mouth. in pregnant women.
Method
Seventy-five pregnant women who were in their 5th to 20th week of
gestation GESTATION, med. jur. The time
during which a female, who has conceived, carries the embryo or foetus in
her uterus. By the common consent of mankind, the term of gestation is
considered to be ten lunar months, or forty weeks, equal to nine calendar
months and a week. took part in this study. All of these women had
experienced at least one episode of nausea either with or without vomiting
in the 24 hours prior to study commencement. None of the women were taking

Hyperemesis Gravidarum Definition
Hyperemesis gravidarum means excessive vomiting during pregnancy.
Description
In pregnant women, nausea and vomiting (morning sickness) are common,
affecting up to 80% of pregnancies. (a condition characterised by

2. vomiting). There were no statistical differences between
the women for severity, length and frequency of nausea and vomiting
episodes.
The women were randomly divided into three groups: 26 in the treatment
group, 25 in the control group and 24 in the placebo group. None of the
women were made aware of which group they had been allocated to. All the
women in this study were asked to keep a diary of nausea and vomiting
episodes for the nine day duration of the intervention.
Those in the treatment group had acupressure wristbands applied to the P6
acupressure point. The wristband was 2.5 cm thick with a cloth covered
semi-sphere shaped button that was placed over the P6 point on the inner
wrist. The women in this group applied pressure to the P6 point digitally.
To ensure the instructions were correctly carried out, written materials
explaining the procedure were also provided.
Women in the placebo group wore the same acupressure wristbands as the
treatment group, but with the button on the upper wrist in the opposite
position to the P6 point. Written instructions were provided to this group
as well to ensure that the wristbands were correctly worn. The control group
did not wear wristbands.
The study's length was nine days. On days 1-3 no wristbands were worn by any
group. During days 4-6 the acupressure bands were used by the treatment and
placebo groups. These bands were taken off at night before going to sleep
and put back on before getting out of bed in the morning. If the bands
needed to be removed at any time over the-day, they had to be replaced
within 15 minutes and this had to be recorded in the diary. On days 7-9 the
wristbands were not worn at all.

through the point of sight, and is the chief line in the projection upon
which all verticals are fixed, and upon which all vanishing points are
found.

Results
There was a highly significant reduction in the frequency of nausea symptoms
between days 1-3 and days 4-6 in the treatment group. The placebo group also
showed a significant reduction in frequency of nausea symptoms in these two
time periods. The control group showed no significant difference between
days 1-3 and 4-6.
There was a significant reduction in the severity of nausea for both the
treatment and the placebo groups between days 1-3 and days 4-6. The control
group showed no difference in nausea severity for the same periods.
There was a significant reduction in the intensity of discomfort for both
the treatment and the placebo groups between days 1-3 and days 4-6, although
the reduction was greater in the treatment group. The control group showed
no difference in nausea severity for the same periods. During days 7-9,
there were no significant differences between any of the groups for
frequency or severity of nausea episodes or for intensity of discomfort.
Conclusion
The researchers concluded that:
acupressure wristbands may have both a therapeutic and a placebo effect on reducing symptoms of nausea and ensuring relief for the patients.
Limitations Of The Study
The researchers noted that women who came to the centre in which the study
took place tended to have their regular medical examinations at similar
appointment times. Thus the possibility that the women might communicate
with each other was created. In an effort to reduce any negative effects
that this may cause, the women who were allocated to the same group were
given appointments on the same day. _
