1 Clinical Trials for Various Conditions
The proposed studies are aimed to measure Tau and P-Tau levels in pre- and postoperative blood, urine, feces and saliva, as well as to assess pre- and postoperative neurocognitive function in children (3 to 5 years old) who will have surgery under general anesthesia (single versus multiple exposures). The studies will establish a system to study biomarkers of the anesthesia/surgery-associated neurocognitive impairment in children and generate hypothesis that Tau or P-Tau serves as the biomarker of such neurocognitive impairment in children.
