Abstract
Summary
The volume of urine, providing the fluid intake is adequate, is not diminished during labor in normal pregnant women. It is, however, decreased in pre-eclampsia or eclampsia, and the forcing of fluids may produce undesirable systemic symptoms and signs.
The parenteral injection of extracts of the posterior lobe of the pituitary gland produced the following changes: 1. A decrease in the volume of urine, an increase in the chloride concentration, and an average rise in the systolic blood pressure of 15 mm. Hg. in normal pregnant, parturient or puerperal women. 2. A markedly decreased volume of urine, an increase in the chloride concentration, and an average rise in the systolic blood pressure of 49 mm. Hg. in pre-eclamptic patients.
