Deliberately Lowering Blood Pressure with Sodium Nitroprusside
The goal of hyptensive anesthesia is the safe reduction of intraoperative blood loss, thus reducing transfusion risks. Previous hypotensive technics had a narrow margin of safety in that cardiac output was usually reduced in proportion to the degree of induced hypotension. This is in contrast to the results of our study, in which Sodium Nitroprusside was used as the sole hypotensive agent. Ni...
متن کاملBlood pressure, sodium intake, and sodium related hormones in the Yanomamo Indians, a "no-salt" culture.
The Yanomamo Indians are an unacculturated tribe inhabiting the tropical equatorial rain forest of northern Brazil and southern Venezuela who do not use salt in their diet. The group therefore presented an unusual opportunity to study the hormonal regulation of sodium metabolism in a culture with life-long extreme restriction of dietary sodium, with parallel observations on blood pressure. Bloo...
متن کاملData Dredging
Suppose there is a given data set and there are a huge number of hypotheses [1] about this data set [2]. If the data is totally random, then say all the hypotheses are actually false. However, owing to the sheer number of hypotheses on a limited data set, it is possible to see some very highly correlated [3] data that are statistically significant [4]. In such cases, data dredging is said to ha...

متن کاملDietary sodium and blood pressure.
The importance of dietary sodium chloride in the regulation of blood pressure has received much attention over the past few years. This area of research and knowledge has been controversial for several reasons. The major reason for controversy is that the science of the relationship is difficult to ascertain. Population science is limited by the narrow range of dietary sodium intake by most pop...
