Brief Summary
Little is known about how implementation of prone position contributes to general anesthesia-induced decrease in cerebral blood flow in infants. The investigators investigated this question in participants undergoing untethering, hypothesizing that cardiorespiratory changes during this procedure would reduce cerebral perfusion.
