Effects of Abdominal Breathing on Anxiety, Blood Pressure, Peripheral Skin Temperature and Saturation Oxygen of Pregnant Women in Preterm Labor / 여성건강간호학회지

PURPOSE: This study was done to examine the effects of abdominal breathing on VAS-Anxiety (VAS-A), blood pressure, peripheral skin temperature and saturation oxygen in pregnant women in preterm labor. METHODS: The study design was a matched control group interrupted time series. Forty-six women matched to gestational age were assigned to either the experimental group (26) or control group (20). Data were collected between March 2007 and May 2008. For the experimental treatment the women performed abdominal breathing 30 times, which took 5 minutes, and did one set of 5-minute abdominal breathing daily for three days. Data collection was done before and after the abdominal breathing to measure VAS-A, blood pressure, peripheral skin temperature and oxygen saturation. Descriptive, chi-square, Mann-Whitney U tests were used to analyze the data with the SPSS/PC+Win 15.0 program. RESULTS: For the experimental group there were significant decreases in VAS-A (Z=-4.37, p=.00), systolic blood pressure (Z=-3.38, p=.00), and an increase in skin temperature (Z=-4.50, p=.00) and oxygen saturation (Z=-3.66, p=.00). CONCLUSION: These findings suggest that abdominal breathing in pregnant women in preterm labor results in decreases in anxiety(VAS-A) including biological evidences such as systolic blood pressure, and increases in peripheral skin temperature and oxygen saturation. Further longitudinal study is needed on the lasting effects and obstetric and neonatal outcomes following abdominal breathing.

Effects of Abdominal Breathing on Anxiety and Labor Time in Primipara Women / 여성건강간호학회지

PURPOSE: This study aimed to examine the effects abdominal breathing on anxiety and length of labor time in primipara women. METHOD: It was a quasiexperimental design with a non-equivalent comparison group, performed from October 11 to December 4, 2007. Thirty-six subjects who received pitocin and met the inclusion criteria were chosen by convenience sampling from the labor room of Y hospital located in Seoul. The intervention of abdominal breathing was 'four seconds of inhale, six seconds of exhale breathing method.' The abdominal breathing was carried out 30 times each when the uterine cervix was dilated 3~4cm and 5~6cm. Psychological anxiety was measured by VAS-A before and after the cervix dilatation to 3~4cm, and 5~6cm. RESULT: Anxiety scores of the experimental was found lower than that of the control group at 3~4cm(z=-3.05, p=.00) and 5~6cm(z=-2.04, p=.04) of cervix dilatation. However, the abdominal breathing was not effective to the length of labor from the active phase thru full dilatation, though there was 56 minutes of difference between the two groups. CONCLUSION: Carrying out the abdominal breathing 30 times at two time points was effective in decreasing anxiety level during labor. Further study is suggested to examine the effects of abdominal breathing on labor time, fetal heart rate, and uterine contraction.
