As resulting variables, length of labor, use of oxytocin, labor pain, use of analgesics, plasma beta-endorphin, serum cortisol, pulse rate, blood pressure, umbilical cord arterial blood pH, Apgar score were measured. Collecting Data were analyzed by t-test, x2 test, repeated measures of ANOVA with SPSS program.
RESULTS
As a results, the length of decerelation phase of the experimental group was significantly shorter than the control group. No significant group effects were found, but significant time effects were found for labor pain, plasma beta-endorphin, serum cortisol, pulse rate and blood pressure. There were no significant differences in other variables between two groups.
CONCLUSION
These findings indicate that aromatherapy during labor could be effective in decreasing labor length. But, any other effects of aromatherapy did not be verified.
