The purpose of this study was to explore the effects of abdominal breathing on relieving anxiety in women diagnosed with preterm labor. METHOD: This was a pilot study, which was based on a repeated pre-post experiment design without a control group. Seven patients with preterm labor who were admitted to Y university medical center, Seoul, Korea, participated in the experiment. They were under receiving ritodrine hydrochloride(Yutopa) as tocolytic therapy and did not have any other complications. The patients were taught abdominal breathing, which is a modified version of Mason's breathing technique. The experimental treatments were done 33 times from February 18 to June 19 in 2005. RESULT: After abdominal breathing, the average psychological anxiety level decreased significantly. The physical anxiety levels of preterm labor patients were measured by blood pressure, pulse, and skin temperature. After abdominal breathing, the average systolic and diastolic blood pressure decreased from 117.3mmHg to 107.6 mmHg (z=-3.85, p<.001) and from 67.3mmHg to 62.7 mmHg (z=-3.14, p<.005), respectively. The average pulse rate also decreased from 97.2/min to 89.8/mim (z=-4.76, p<.001). The average skin temperature increased from 94.0 to 94.9(z=-4.80. p<.001).
Abdominal breathing is effective for relieving anxiety of women diagnosed with preterm labor. This study, however, has been limited to short-term effects, and therefore further studies are required in order to examine the long-term effects of abdominal breathing.
