Two-year-old Zion Gastelum died of brain damage following dental treatment under general anesthetic at an Arizona clinic a year ago. Now, details have emerged of a lawsuit that alleges staff repeatedly muted the alarm on his heart rate monitor, and says an oxygen tank was either empty or faulty.
Gastelum was put under general anesthetic at Kool Smiles clinic in Yuma, Arizona, on Dec. 16, 2017. He never regained consciousness and died four days later from brain damage caused by lack of oxygen.
