What is general anesthesia? ... You’re unconscious; you’re not supposed to remember; it’s nice if it doesn’t hurt; it’s good if you’re not moving around while the surgeons are operating. And if you take those first four things by themselves, they’re synonymous with death. On that long list of things that are not cool, that’s not cool. This next part is where we sort of earn our money… we keep the patient alive.
