Changes in systemic and cerebral hemodynamics in preterm infants during early transitional circulation are complex and may differ between infants with or without intraventricular hemorrhage (IVH).
This article was published in the following journal.
Name: Pediatric research
To maintain cerebral blood flow (CBF), cerebral blood vessels dilate and contract in response to blood supply through cerebrovascular reactivity (CR).
Insufficient nitric oxide (NO) bioavailability plays an important role in endothelial dysfunction and increased NO has the potential to enhance cerebral blood flow (CBF). Dietary supplementation with ...
Background Hypercarbia increases cerebral blood flow secondary to cerebral vasodilatation, while hypocarbia can lead to vasoconstriction with a subsequent decrease in cerebral blood flow. The aim of t...
Hepatitis C viral (HCV) infection is associated with systemic inflammation and metabolic complications that might predispose patients to atherosclerosis, including cerebrovascular atherosclerosis. The...
The myogenic reactivity of the middle cerebral arteries (MCA) protects the brain by altering the diameter in response to changes in lumen pressure. Large conductance potassium (BK) channels are known ...
The investigators hypothezised that CO2-reactivity of cerebral vessels is affected by systemic non-pulsatile blood flow. Patients undergoing elective cardiac surgery with CPB were enrolled...
The etiology of Alzheimer's disease (AD), the most common type of dementia, remains largely undefined and the early diagnostic and effective treatments are still not available. In addition...
Septic encephalopathy is an important complication of sepsis. Why some patients with sepsis develop septic encephalopathy is unknown. We will investigate whether patients who develop this ...
Background: fluctuation of cerebral blood flow and oxygenation in neonates who undergo intensive care is an important risk factor for risk of neurodevelopmental impairment. Near infrared s...
Obstructive sleep apnoea (OSA) is a highly prevalent sleep-related breathing disorder associated with adverse cardiovascular outcome. Underlying mechanisms are subject of debate. A causal ...
A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.
Critical care treatment using intensive monitoring and aggressive management of perioperative hemodynamics in high risk patients,
A noninvasive technique that uses the differential absorption properties of hemoglobin and myoglobin to evaluate tissue oxygenation and indirectly can measure regional hemodynamics and blood flow. Near-infrared light (NIR) can propagate through tissues and at particular wavelengths is differentially absorbed by oxygenated vs. deoxygenated forms of hemoglobin and myoglobin. Illumination of intact tissue with NIR allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition.
An ergot derivative that has been used as a cerebral vasodilator and in peripheral vascular disease. It has been suggested to ameliorate cognitive deficits in cerebrovascular disease.
A calcium channel blockader with preferential cerebrovascular activity. It has marked cerebrovascular dilating effects and lowers blood pressure.
