Measurement of cerebral blood flow during cardiopulmonary bypass with near-infrared spectroscopy

Autor: Fenella J. Kirkham, Paul M. Kirshbom, A. David Edwards, Idris Roberts, Chris E. Cooper, Martin Elliott, Penny Fallon

Publikováno v: The Journal of Thoracic and Cardiovascular Surgery. 115(1):94-102

Objective: A novel noninvasive method for repeatedly measuring cerebral blood flow during cardiopulmonary bypass by near-infrared spectroscopy is described. The reproducibility of the method is investigated and a comparison is made with an establishe

The relation between arterial oxygen tension and cerebral blood flow during cardiopulmonary bypass

Autor: M. Onoe, A Lloyd-Thomas, P. Fallon, Martin J. Elliott, Fenella J. Kirkham, Gabriel Chow, Idris Roberts, A D Edwards

Publikováno v: European Journal of Cardio-Thoracic Surgery. 11:633-639

Neurological impairment occurs in up to 25% of infants undergoing cardiopulmonary bypass with or without circulatory arrest. Potential causes include alterations in cerebral blood flow, hypoxia and embolisation. During cardiopulmonary bypass, arteria

Cerebral blood volume response to changes in carbon dioxide tension before and during cardiopulmonary bypass in children, investigated by near infrared spectroscopy

Autor: Martin Elliott, A D Edwards, Idris Roberts, Fenella J. Kirkham, A Lloyd-Thomas, Fallon P

Publikováno v: European Journal of Cardio-Thoracic Surgery. 8:130-134

Neurological impairment may occur following cardiopulmonary bypass (CPB) and the effect of CPB on cerebrovascular control may be important in the mechanism of cerebral injury. We have used near infrared spectroscopy (NIRS) to observe cerebral haemody

Cerebral hemodynamics during cardiopulmonary bypass in children using near-infrared spectroscopy

Autor: Fenella J. Kirkham, A Lloyd-Thomas, Idris Roberts, A. David Edwards, Penny Fallon, Martin J. Elliott, Richard Maynard

Publikováno v: The Annals of Thoracic Surgery. 56:1473-1477

We describe a new noninvasive method using near-infrared spectroscopy for monitoring cerebral hemodynamics during cardiopulmonary bypass in children. All patients were undergoing open heart operations for repair of congenital heart defects. Standardi

Randomized double-blind controlled trial comparing the effects of ibuprofen with indomethacin on cerebral hemodynamics in preterm infants with patent ductus arteriosus

Autor: Jayesh C Patel, P A Hamilton, Denis Azzopardi, A. David Edwards, Idris Roberts

Publikováno v: King's College London

A prospective randomized controlled trial was performed to compare the effects of ibuprofen with indomethacin on cerebral hemodynamics measured using near infrared spectroscopy in preterm infants during treatment for patent ductus arteriosus. Infants

Nitric oxide synthase inhibition and delayed cerebral injury after severe cerebral ischemia in fetal sheep

Autor: Alexander D. Edwards, Peter D. Gluckman, Carina Mallard, Chris E. Williams, Idris Roberts, K A Marks

Publikováno v: Pediatric research. 46(1)

After transient cerebral ischemia in fetal sheep, delayed disruptions in cerebral energetics are represented by a delayed increase in cortical impedance, a progressive decrease in the concentration of oxidized cytochrome oxidase as measured by near-i

The relation between pump flow rate and pulsatility on cerebral hemodynamics during pediatric cardiopulmonary bypass

Autor: A Lloyd-Thomas, Fenella J. Kirkham, Gabriel Chow, Idris Roberts, Angie Wade, A. David Edwards, Martin Elliott

Publikováno v: The Journal of thoracic and cardiovascular surgery. 114(4)

Objectives: Neurologic impairment, at least partly ischemic in origin, has been reported in up to 25% of infants undergoing cardiopulmonary bypass, with or without circulatory arrest. Controversy continues about the effect of pump flow, pulsatile or

Monitoring of cerebral hemodynamics during open-heart surgery in children using near-infrared intensity-modulated spectroscopy

Autor: Matthias Kohl-Bareis, Idris Roberts, David T. Delpy, Mark Cope, Gabriel Chow, Russell Watson

Publikováno v: Optical Tomography and Spectroscopy of Tissue: Theory, Instrumentation, Model, and Human Studies II.

Neurological impairments following cardiopulmonary bypass (CPB) during open heart surgery can result from microembolism and ischaemia. Here we present preliminary results from monitoring cerebral hemodynamics during CPB with near infrared intensity m
