Mariela's post-cooling MRI looked normal, which suggested she wouldn't have any long-term cognitive problems due to the lack of oxygen, according to Ms. Peloquin.
"Sometimes we look at it like a rebirth, " said Susan Peloquin, a UCSF neonatal intensive care nurse who specializes in hypothermia treatment and helped treat Mariela.
She moved her fingers and squirmed, her mouth opening and her tongue rooting around normal behavior for a newborn and a very good sign of Mariela's prognosis, Ms. Peloquin said.
