The most common cause of renal artery stenosis is atherosclerosis, the same condition that causes narrowing of the arteries in coronary heart disease and stroke, and the risk factors are the same as well. Cholesterol plaques build up along the walls of the renal artery and gradually cause narrowing.
Oxytocin is a commonly used uterotonic that can cause significant and even fatal hypotension, particularly when given as a bolus. The resulting hypotension can be produced by a decrease in systemic vascular resistance or cardiac output through a decrease in venous return.
Pitocin is the synthetic brand name of the labor hormone, Oxytocin. This is the hormone that causes the uterus to contract during labor, and to contract after delivery, preventing postpartum hemorrhage.isks of Pitocin include contractions that are too close together and that don't give the uterus a chance to relax and recover, which can result in fetal distress. Maternal risks of the medication are water intoxication, pulmonary edema and abnormal sodium levels.
