Cerebral oximetry

[Cerebral oximetry].

Dr. Frost has no relevant financial conflicts to disclose. C erebral oximetry has been studied for more than 30 years, and has been commercially available to clinicians for more than 2 decades. 1,2 However, whereas pulse oximetry has been a standard of care for decades, only recently has cerebral oximetry been extensively studied and adapted to investigate changes in oxygen delivery to the brai...

Cerebral oximetry: a replacement for pulse oximetry?

Cerebral oximetry has been around for some 3 decades but has had a somewhat checkered history regarding application and reliability. More recently several monitors have been approved in the United States and elsewhere and the technique is emerging as a useful tool for assessing not only adequate cerebral oxygenation but also tissue oxygenation and perfusion in other organs.

Cerebral Oximetry – Any Value ?

Cerebral oximetry monitoring, used with the intention of optimizing perioperative outcomes, is increasingly being used in the setting of both cardiac and non-cardiac surgery. Cerebral oximetry had its early beginnings in the 1980s with the work of Jöbsis and colleagues. By using multi-wavelength light sources in the near infrared range, these early investigations demonstrated the potential util...

Cerebral oximetry and laparoscopic surgery

Laparoscopic surgery, although enjoying ever­ increasing popularity and presenting new anaesthetic challenges, can be potentially hazardous due to the intraperitoneal insufflation of CO 2 that is required for the procedure. Laparoscopy may lead to possibly harmful cardiovascular and respiratory alterations that could possibly be harmful for the patient. Numerous studies have focused on the effe...
