Assessment of Amplitude and Temporal Differences of Cerebral Oxygen Saturation in Response to Hypotension Across Multiple Cerebrovascular Territories During Shoulder Surgery

Despite limitations, such as small sample size and the exclusion of large number of events, this pilot study demonstrates that StO2 changes in response to hypotension in multiple brain regions can be measured and compared during surgery, providing insights and facilitating investigation of the selective vulnerability of brain regions. Future exploration will enhance our understanding of cerebral ischemia pathophysiology and perioperative stroke.
