Renal perfusion in scleroderma patients assessed by microbubble-based contrast-enhanced ultrasound [PDF]

, 2012
OBJECTIVES: Renal damage is common in scleroderma. It can occur acutely or chronically. Renal reserve might already be impaired before it can be detected by laboratory findings.

Inhibition of Trophoblast-Induced Spiral Artery Remodeling Reduces Placental Perfusion in Rat Pregnancy. [PDF]

, 2010
Rats harboring the human angiotensinogen and human renin genes develop preeclamptic features in pregnancy. The preeclamptic rats exhibit a deeper trophoblast invasion associated with a reduced resistance index by uterine Doppler.

Computer-assisted ex vivo, normothermic small bowel perfusion [PDF]

, 2000
Background: In the present study, a technique for computer-assisted, normothermic, oxygenated, ex vivo, recirculating small bowel perfusion was established as a tool to investigate organ pretreatment protocols and ischemia/reperfusion phenomena.

Pleth variability index measured in the sitting position before anesthesia can predict spinal anesthesia-induced hypotension in cesarean section: An observational study

Journal of Obstetric Anaesthesia and Critical Care, 2022
Background: Hypotension induced by spinal anaesthesia during caesarean section can have devastating effects on the parturient and foetus. This study investigated the ability to predict spinal anaesthesia-induced hypotension via the perfusion index and ...

Comparison of non-invasive haemodynamic monitors of stress response to endo-tracheal intubation with perfusion index in patients undergoing elective surgery

Journal of Society of Surgeons of Nepal, 2020
Introduction: Laryngoscopy and intubation is always associated with a short term reflex sympathetic pressor response. The perfusion index is an indirect, non-invasive, and continuous measure of peripheral perfusion by pulse oximeter which can detect the ...

Impact of Ig-Therasorb (R) immunoapheresis on stability of xenogeneic ex vivo porcine liver perfusion - Value of aminotransferases and flow rates for the assessment of metabolic graft viability [PDF]

, 2000
Due to growing shortage of donor organs, the concept of extracorporeal pig liver perfusion in the treatment of acute liver failure has been rediscovered.

Quantitative Analysis of Brain CT Perfusion in Healthy Beagle Dogs: A Pilot Study

Veterinary Sciences, 2023
Brain computed tomography (CT) perfusion is a technique that allows for the fast evaluation of cerebral hemodynamics. However, quantitative studies of brain CT perfusion in veterinary medicine are lacking. The purpose of this study was to investigate the

Perfusion index as a predictor of hypotension following propofol induction - A prospective observational study

Indian Journal of Anaesthesia, 2017
Background and Aims: Hypotension during propofol induction is a common problem. Perfusion index (PI), an indicator of systemic vascular resistance, is said to be predictive of hypotension following subarachnoid block.

Renal Vascular Perfusion Index in a Canine Model [PDF]

Ultrasound in Medicine & Biology, 2009
Decreased renal perfusion plays an important role in the progression toward renal failure. In this study, a novel measure was proposed to quantify renal perfusion using canine model. Serial renal vascular images at different vascular areas including the whole vascular tree, interlobar, arcuate and interlobular vessels were captured.
