Intravenous anesthesia decreases S100B in humans (MD 0.34 (95% CI: 0.23-0.48, P < 0.00001)).
“Furthermore, plasma levels of S-100β protein, a marker for neural injury, were significantly lower in the intravenous anesthesia group”

Intravenous anesthesia lowers the risk of postoperative cognitive dysfunction in humans (OR 0.96 (95% CI: 0.73-1.26, P < 0.00001)).
“However, on Day 7, the incidence of POCD was significantly lower in the intravenous anesthesia group, with a combined Odds Ratio (OR) of 0.96”
