Results
There were 85 women randomized to ginger
(group A) and 85 women to dimenhydrinate (group B).
There were 8 women in group A and 11 women in group
B who were lost to follow up. The baseline characteristics
were similar in both groups (Table 1). After adjusting
the variation of the difference nausea score and
vomiting times before the treatment in both groups
(day 0), the mean of nausea score in day 1-7 of the
treatment were decreased in both groups (Fig. 1). The
daily mean nausea scores between both groups were
not statistically different (p > 0.05 ) (Table 2). The frequency
of vomiting times in day 1-7 of the treatment
was decreased in both groups (Fig. 2). The daily mean
vomiting times in the dimenhydrinate group in day 1-2
of the treatment were less than the ginger group with
statistical significance (p < 0.05). After day 3-7 post
treatment, the daily mean vomiting times in both
groups were not statistically different (p > 0.05). The
occurrence of drowsiness in the ginger group and
dimenhydrinate group were 5/85 (5.88%) versus 66/85
(77.64%) (p < 0.01). The occurrence of heart burn was
13/85 (15.2%) versus 9/85 (10.58%) (p = 0.403), respectively.
No other adverse effect was observed in both
groups during the one-week follow up.
