Her mother was supposed to go home the next day.
Sheree Thein's mom, Jadeen Rivard, was hospitalized in 2014 with a partial intestinal blockage. She had her stomach pumped and after a few days she was feeling better. "There was nothing going on with her that gave us any reason for concern," Thein said.
Her mom didn't survive the night.
Thein said her mother was a victim of what's called "Dead in Bed," a phenomenon that's well-known within the medical community, but not discussed much with the general public.
The hospital could offer no answers and an autopsy was inconclusive. But the exam didn't include a toxicology report and Thein's family became convinced that if it had, it would have shown that her mother died of opioid intoxication from Dilaudid, the common but potent painkiller she was given during her hospitalization.
Experts who reviewed her medical records said the doses seemed unusually high for someone being treated for such a minor procedure. Cumulatively, they said, it could have been enough to make a patient stop breathing, especially someone like Rivard who was 80 and hadn't been on opioids before.
It usually happens in hospital wards that aren't intensive care units. Patients on painkillers, often recovering from surgery, quietly suffer respiratory failure while asleep.
Frank Overdyk, an anesthesiologist and national patient safety expert, said an estimated 3,000 to 5,000 Americans die that way every year.
