Key result
Cerebral venous blood gas measurements did not provide a reliable index of cerebral ischaemia during temporary carotid clamping in patients referred for carotid ligation.
Why the study?
Do jugular venous blood gas measurements reliably predict brain ischaemia during temporary carotid clamping in patients referred for carotid ligation?
Do jugular venous blood gas measurements reliably predict brain ischaemia during temporary carotid clamping in patients referred for carotid ligation?
Jugular venous blood gas measurements are not a reliable predictor of brain ischemia during carotid clamping.
No takes yet. Share an insight, caveat, or question.
Jugular venous blood gas measurements should not guide carotid ligation decisions; Level 4 data leaves open the need for validated ischaemia monitors.
Jawad et al. (2008) studied this question. Cerebral venous blood gas measurements did not provide a reliable index of cerebral ischaemia during temporary carotid clamping in patients referred for carotid ligation.
