Menorrhagia and uterine artery blood flow.
Menorrhagia is a significant problem in women of reproductive age. In half of the cases no specific aetiology is known. Vascular factors play a role but remain poorly understood. We chose to study whether any association exists between the flow impedance of uterine arteries and the amount of menstrual blood loss. The study population consisted of 60 spontaneously menstruating 35- to 49-year-old...
متن کاملUterine artery blood flow, fetal hypoxia and fetal growth.
Evolutionary trade-offs required for bipedalism and brain expansion influence the pregnancy rise in uterine artery (UtA) blood flow and, in turn, reproductive success. We consider the importance of UtA blood flow by reviewing its determinants and presenting data from 191 normotensive (normal, n = 125) or hypertensive (preeclampsia (PE) or gestational hypertension (GH), n = 29) Andean residents ...
متن کاملIncreasing maternal blood pressure with ephedrine increases uterine artery blood flow velocity during uterine contraction.
BACKGROUND During labor, ephedrine is widely used to prevent or to treat maternal arterial hypotension and restore uterine perfusion pressure to avoid intrapartum fetal asphyxia. However, the effects of ephedrine on uterine blood flow have not been studied during uterine contractions. The purpose of the study was to assess the effects of ephedrine on uterine artery velocities and resistance ind...
متن کاملUterine blood flow and uterine renin secretion.
Experiments were carried out in pregnant nephrectomized rabbits to determine the relationship between uterine blood flow and uterine renin secretion. Uterine blood flow was measured by the percentage distribution of radioactive microspheres injected into the left ventricle which lodged in uterus and placenta, and cardiac output was measured by dye dilution. In 40 animals, 24 hr after nephrectom...
متن کاملaspirin and preeclampsia prevention in patients with abnormal uterine artery blood flow
background preeclampsia is one of the leading causes of maternal mortality and morbidity. its prevalence varies between 10-25% among high-risk pregnant patients. objectives the aim of this study was to determine whether treatment with acetylsalicylic acid (asa) reduces the incidence of preeclampsia among pregnant women with abnormal uterine artery flow. patients and methods in this double-blind...
