The purpose of this study was to investigate the effects of anxiety reduction before an operation by relaxation breathing techniques. The participants were 15 patients who would be having a myomectomy or abdominal total hysterectomy by general anesthesia and open surgery.
The intervention was to instruct the breathing techniques when an operation was decided on in the outpatient department. We submitted participants to breathing techniques that were conducted for three minutes every day from one week before hospitalization. During the term that breathing techniques were conducted, we measured STAI (State anxiety) and experience of breathing techniques. Also, we measured STAI and nervous activity (HF, LF/HF, heart rate) on the day of hospitalization.
As a result, the STAI score after the breathing techniques was significantly decreased compared with before breathing techniques from one week before hospitalization. And, HF (index of parasympathetic nervous activity) was significantly increased. Heart rate and LF/HF (index of sympathetic nervous activity) did not change. Further, the STAI score was significantly decreased on the day of hospitalization.
It was suggested that the reduction of anxiety before operation was due to the breathing techniques.
