Continuous monitoring of jugular bulb venous oxygen saturation for evaluation of cerebral perfusion during carotid endarterectomy.
In this study we examined whether continuous monitoring of jugular bulb venous oxygen saturation (SjO2) is applicable for the evaluation of cerebral hypoperfusion during carotid endarterectomy (CEA). The subjects were 25 patients who underwent elective CEA under general anaesthesia. After the carotid stump pressure (SP) was measured, SjO2 and the somatosensory evoked potentials (SEP) were monit...
متن کاملInternal jugular venous oxygen tension as an index of cerebral blood flow during carotid endarterectomy.
A QUANTITATIVE relationship between arterial carbon dioxide tension (Paco2) and cerebral blood flow (CBF) measured indirectly by the nitrous oxide or 85krypton techniques has been demonstrated by many investigators in normal manl4 and in anesthetized man.5-8 We have calculated this relationship to be CBF =1.31 Paco2+ 7.3 from the data of Kety and Schmidt' 2 who studied unanesthetized healthy su...
متن کاملValidity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
متن کاملCerebral protection during carotid endarterectomy.
Cerebral Protection During Carotid Endarterectomy • Carotid endarterectomy was performed on 73 occasions using the following regimen during the operative period: (1) general anesthesia with normothermia, (2) maintaining a normal or slightly elevated arterial oxygen tension (Pao,, (3) maintaining a normal or low arterial carbon dioxide tension (Pco,), (4) maintaining systemic arterial pressure (...
متن کاملCerebral blood flow during carotid endarterectomy.
Cerebral blood flow (CBF) was measured during 28 carotid endarterectomies in 25 patients, by injection of 133Xe into the exposed internal carotid artery (ICA). Twenty-three patients had episodic cerebral or retinal ischemia and five had neurologic deficits before operation. Initial CBF values were variable. Increases of PaC02 caused CBF to increase in four of six patients, to increase slightly ...
