Maternal comfort
Three studies examined maternal comfort using different
methods [11,12,15]. We judged that data pooling would
be inappropriate in this case, as the conversion to a common
scale was not feasible. In one study [12], a maternal
comfort score developed by the authors themselves was
used to evaluate maternal reactions to uterine contractions,
including certain behavioral and physiological
signs. The overall mean comfort score during the first
stage of labor did not differ significantly between the two
groups. Another study evaluated women's experiences
and the results suggest more women rating their experiences
positively in the study group compared to the control
group [10]. The third study used a visual-analog scale
to evaluate maternal satisfaction during labor [15], resulting
in no statistically significant difference between the
two groups.
