September 16, 2024 at 10:09 PM. [ Daniela Cossio] Pregnancy brain really does exist, according to one of the first detailed maps of human-brain changes before, during and after those crucial nine ...
The combined effect of the decreased serum concentrations of both carbon dioxide and bicarbonate leads to a slight overall increase in blood pH (to 7.44 compared to 7.40 in the non-pregnant state) . If an arterial blood gas (ABG) specimen is drawn on a pregnant woman, it would therefore reveal respiratory alkalosis (from the decrease in serum ...
For the first time, researchers have mapped out the very real physical changes of “pregnancy brain,” the changes that a mother’s brain undergoes while carrying a baby. There’s “so much ...
Eclampsia is the onset of seizures (convulsions) in a woman with pre-eclampsia. [ 1 ] Pre-eclampsia is a hypertensive disorder of pregnancy that presents with three main features: new onset of high blood pressure, large amounts of protein in the urine or other organ dysfunction, and edema. [ 7 ][ 8 ][ 9 ] If left untreated, pre-eclampsia can ...
Obstetrics and gynaecology. Aortocaval compression syndrome also known as Supine hypotensive syndrome is compression of the abdominal aorta and inferior vena cava by the gravid uterus when a pregnant woman lies on her back, i.e. in the supine position. It is a frequent cause of low maternal blood pressure (hypotension), which can result in loss ...
Placental insufficiency or utero-placental insufficiency is the failure of the placenta to deliver sufficient nutrients to the fetus during pregnancy, and is often a result of insufficient blood flow to the placenta. The term is also sometimes used to designate late decelerations of fetal heart rate as measured by cardiotocography or an NST ...
Cerebral autoregulation is a process in mammals that aims to maintain adequate and stable cerebral blood flow. While most systems of the body show some degree of autoregulation, [1] the brain is very sensitive to over- and underperfusion. Cerebral autoregulation plays an important role in maintaining an appropriate blood flow to that region.
Gestational hypertension or pregnancy-induced hypertension (PIH) is the development of new hypertension in a pregnant woman after 20 weeks' gestation without the presence of protein in the urine or other signs of pre-eclampsia. [1] Gestational hypertension is defined as having a blood pressure greater than 140/90 on two occasions at least 6 ...
