Combined with a laparotomy, the procedure results in a Caesarean section that removes the fetus, thereby abolishing the aortocaval compression caused by the pregnant uterus. [1] This improves the mother's chances of return of spontaneous circulation , and may potentially also deliver a viable neonate . [ 1 ]
Osmolality of blood increases with dehydration and decreases with overhydration. In normal people, increased osmolality in the blood will stimulate secretion of antidiuretic hormone (ADH). This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma. A low serum osmolality will suppress the ...
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [1] This may be due to either a loss of both salt and water or a decrease in blood volume.
Hypovolemic shock results from depletion of intravascular volume, whether by extracellular fluid loss or blood loss. The body compensates with increased sympathetic tone resulting in increased heart rate, increased cardiac contractility, and peripheral vasoconstriction.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
A discredited study that set off a flurry of interest in using an antimalarial drug to treat COVID-19 has now been formally withdrawn. A scientific journal on Tuesday retracted the March 2020 ...
An analysis of a sample of comments carried out by market research firm OneCliq found the vast majority - four-fifths - contained criticism of the healthcare system.
A Lindbergh perfusion pump, c. 1935, an early device for simulating natural perfusion. Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, [1] usually referring to the delivery of blood to a capillary bed in tissue.
