Scientific evidence supports spontaneous physiologic approaches to second-stage labor care; however, most women in US hospitals continue to receive direction from nurses and birth attendants to use prolonged Valsalva bearing-down efforts as soon as the cervix is completely dilated. Delaying maternal bearing-down efforts during second-stage labor until a woman feels an urge to push (laboring dow...

Abstract Background: Insufficient uterine activity or hypotonic uterine contraction is a common reason and the cause of abnormal labor progress that can be corrected with oxytocin. Realizing this fact that undue prolongation of labor may contribute to prenatal morbidity has resulted in using oxytocin infusion in different kinds of ineffective uterine contractions. Materials and methods: In th...

More women with complex congenital heart disease are now surviving into childbearing age. Most of these women have residual hemodynamic lesions that may impair cardiovascularadaptation to pregnancy related physiologic changes. The second and third trimesters of pregnancyare associated with significant increase in preload, and heart rate with slight decrease in afterload. Labor is associated wit...

Physiologic events in the last few weeks of pregnancy coupled with the onset of spontaneous labor are accompanied by changes in the hormonal milieu of the fetus and its mother, resulting in preparation of the fetus for neonatal transition. Rapid clearance of fetal lung fluid is a key part of these changes, and is mediated in large part by transepithelial sodium reabsorption through amiloride-se...

Pregnancy is a complex state in woman's life. It associated with anatomical and physiologic changes that greatly affect not only the mother but living fetus inside her womb. This case of 22-year-old woman at 36 5/7 weeks age gestation presented intractable tachycardia. The patient emergency room cardiorespiratory distress conjunction preterm labor.

The active phase of first stage labor is generally defined as the period between 3 cm to 4 cm to complete cervical dilatation, in the presence of regular uterine contractions. Most women will experience this portion of labor within hospital obstetric units, where care commonly features restriction to bed, electronic fetal monitoring, early treatment of "slow" labors, and few pain management opt...
