Introduction:The present study was conducted to evaluate
the effects of Hypericum Perforatum ointment on perineal pain intensity following
episiotomy among primiparous women.
Methods This triple-blind clinical trial was performed on 98
eligible primiparous women referring to selected educational hospital of Tehran University
of Medical Sciences for normal vaginal delivery. Block Randomization (in 1; 1 ratio) was
used to categorize the participants continuously into two groups: intervention (using
Hypericum Perforatum ointment) and control (using placebo ointment). Participants in each
group used ointments (about 3 grams each time) on episiotomy site, twice a day and for a
period of ten days. Our primary outcome was the pain intensity in different intervals
following episiotomy. The data were analyzed by SPSS software (version 13) using student's
t test, Mann-Whitney U test and chi-square test.
Results: We missed 14 participants during the study and
analyzed the data from 42 participants in each group. The mean of pain scores revealed no
significant differences before (mean difference=-0.33; P=0.46) and four hours (mean
difference=0.57; P=0.13) after ointments use, between the intervention and control groups,
while these differences were significant after eight hours (mean difference=2.17;
P<0.001), five days (mean difference=2.20; P<0.001) and ten days (mean
difference=2.21; P<0.001) following the intervention.
Conclusion: Using Hypericum Perforatum ointment as a
noninvasive, simple and effective topical formulation, can significantly reduce pain
intensity of episiotomy site.
