Tissue Oxygen Index and Pulsatility Index in Orthopedic Surgery: a NIRS and TCD Pilot Trial

Completed
Conditions
Cerebral Microemboli
Registration Number
NCT02340416
Lead Sponsor
Medical University of Vienna
Brief Summary

Cerebral microemboli (ME) are frequently generated during major orthopaedic surgery. The primary objective of this study was applying novel transcranial Doppler (TCD) ultrasound software algorithm to quantify (ME load/15 minutes) and qualify (particulate vs. gaseous) ME, detected as high-intensity transient signals (HITS) in both middle cerebral arteries (MCAs) before and after orthopaedic surgery.
