It's impossible to describe the panic that comes over you when your pager goes off in the middle of the night. You heart starts to race. Your mind freezes. Your fingers go numb. You're invested. There's someone's mom, dad, kid. And now it's on you because that someone's life is now in your hands. Surgeons, we're always investing in our patients. But when your patient's a child, you're responsible. Responsible for whether or not that child survives. And that's enough to terrify anyone.
