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