Method： If the HCG levels during the late pregnancy were related to the delivery mechanism was studied by using the β -HCG changes of 100 women pregnant for 36 weeks, 37 weeks, 38 weeks, 39 weeks, 40 weeks, and 41 weeks, and also the [3 -HCG changes when their uterine orifice was opened for 3cm near the time of labor as the clinical data. All these cases were found to suffer no clinical complications. Result： The difference in HCG changes during the late pregnancy was of no statistical significance （P〉0.05）. Conclusion： The β-HCG levels change during the late pregnancy is not significantly correlated with the labor onset time, and the labor onset time is unpredictable with the monitoring of the HCG levels change during the late pregnancy.展开更多

OBJECTIVE： To determine whether breathing exercises for pregnant women during the second stage of labor have beneficial effects on maternal pain, duration of labor, and the first-minute Appearance, Pulse, Grimace, Activity and Respiration （APGAR） scores. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： This randomized clinical trial involved 250 pregnant women, who were randomly divided into two groups： intervention group （IG; n = 125） and control group （CG; n = 125）. IG received one session breathing exercise training and performed breathing exercises during the second stage of labor versus the CG that did not receive any breathing exercise training. MAIN OUTCOME MEASURES： The effects of breathing exercises on maternal pain were determined by Visual Analogue Scale （VAS）, duration of the second stage of labor, and the first-minute APGAR scores. RESULTS： The mean age of the participants was （23.2 _＋ 4.2） （range： 18 to 42） years. Both IG and CG had similar baseline characteristics in terms of age, education level, occupation, and smoking （P 〉 0.05）. The mean VAS scores of IG and CG were （88.2 ＋_ 6.3） and （90.5 ＋_ 7.0）, respectively （P 〈 0.001）. The duration of the second stage of labor was （369.6 ＋ 92.0） s for IG and （440.7 ＋ 142.5） s for CG （P 〈 0.001 ）. The mean first-minute APGAR scores were （8.84 ＋ 0.50） for IG and （8.73 ＋ 0.89） for CG （P 〉 0.05）. CONCLUSION： Based on this study, breathing exercises with deep inhalation and exhalation in pregnant women are effective in reducing the perception of labor pain and shortening the duration of the second stage of delivery. Therefore, we recommend breathing exercises as an effective modality for labor pain management and shortening the duration of labor.
