BACKGROUND: Hydration has been proposed as a treatment for women with preterm labour. Theoretically, hydration may reduce uterine contractility by increasing uterine blood flow and by decreasing pituitary secretion of antidiuretic hormone and oxytocin. OBJECTIVES: To evaluate the effectiveness of intravenous or oral hydration to avoid preterm birth and its consequences in women with preterm [...]

Arginine vasopressin, a hypothalamic peptide hormone, has multiple physiological functions, including body water regulation, control of blood pressure and effects on body temperature, insulin release, corticotropin release, memory and social behaviour. These functions are achieved via at least three specific G-protein-coupled vasopressin receptors. Development of specific vasopressin receptor antagonists in recent years is helping to [...]
OBJECTIVE: To investigate whether oral or intravenous hydration affects oligohydramnios in cases with normal biophysical profile scores. STUDY DESIGN: One hundred twenty-four gravidas with singleton pregnancies at or near term were identified during a 16-month period retrospectively as having oligohydramnios. A total of 50 subjects with normal biophysical profiles (8 of 10) whose labor was [...]
The discovery of four major water channels in the kidney, namely aquaporins (AQP) 1, 2, 3 and 4, has allowed a substantial increase in our understanding of renal water regulation in health and disease. This review discusses the renal aquaporin water channels in the urinary dilution and concentrating defects in cardiac failure, cirrhosis, syndrome of [...]

OBJECTIVE: To determine the effect of maternal hydration with intravenous (i.v.) isotonic fluid, i.v. hypotonic fluid, and oral water on amniotic fluid index (AFI) in women with oligohydramnios. METHODS: Patients with low AFI and gestational age over 35 weeks without maternal complications were randomized into four groups (2 L/2 h i.v. isotonic fluid, 2 L/2 [...]
