Background: Our study evaluated changes in cerebral arterial oxygen saturation (rSO 2)
during cardiopulmonary bypass (CPB) that were caused by changes in arterial carbon …

Background: Insufflation of carbon dioxide (CO2) to the operative field has been used to
prevent major organ injury attributed to air embolisms in cardiac surgery. However, it may be …

In patients with cerebrovascular disease, hypercarbia may cause redistribution of regional
cerebral blood flow from marginally perfused to well-perfused regions (intracerebral steal) …

BACKGROUND: The purpose of this multicenter pilot study was to:(1) determine the
frequency of regional cerebral oxygen saturation (rScO 2) desaturations during cardiac …

Objective: In this study, the hypothesis that cardiopulmonary bypass (CPB) alters the
cerebral blood flow (CBF) vasoconstrictive response to hyperoxia was tested. Design: A …

A significant number of patients suffer transient neuropsychological dysfunction after
coronary artery bypass graft (CABG) surgery. Recent studies have implicated reduced levels …

Methods In 35 consecutive patients undergoing elective off-pump coronary artery bypass
grafting, cerebral oxygen saturation was measured by near infrared spectroscopy. A 20 …

Objectives Norepinephrine is used to increase mean arterial pressure during
cardiopulmonary bypass. However, it has been suggested that norepinephrine could …

Objective: To determine the effects of hemodilution, PaCO2, PaO2, arterial pressure, and
temperature on cerebral oxygenation during mild hypothermic cardiopulmonary bypass …

We read with great interest the report of Leyvi et al 1 entitled “Assessment of Cerebral
Oxygen Balance During Deep Hypothermic Circulatory Arrest by Continuous Jugular Bulb …
