She was admitted to the hospital and received two steroid shots. Doctors later said the shots might have sped up Addyson's lung development and contributed to her survival.
After a few days in the hospital, McCall was discharged June 24 with a prescription for Procardia, a blood pressure medication. But she soon learned she was allergic to the medicine.
She was again admitted into the hospital June 27. Doctors placed her in a high-risk pregnancy birthing suite because of the issues around her high blood pressure.
“That's when we were told, ‘You're going to be here for the rest of your pregnancy. We don't expect anything to happen until about 33 weeks.'”
The next day was the first day of her third trimester. That morning, she had a few ultrasounds and was maintaining a steady blood pressure. A few hours later, she went into labor.
Had McCall not been in the hospital when she experienced the placental abruption, doctors suspect she and Addyson would not have made survived.
Twelve minutes passed between the time the abruption occurred and when Addyson was born.
Doctors had to work fast against the risk of losing the baby and possibly Roseanna.
Roseanna had lost a lot of blood, and the placenta was no longer supplying Addyson with oxygen, food and life support, said Dr. Anne Wlodaver, a neonatologist at The Children's Hospital who was one of the several medical staff assisting with the delivery.
“When we got the baby, we got a little limp body with no life in her, and she was extremely white, constricted, a little heart rate, but that's about it,” she said.
The newborn brain can tolerate a lack of oxygen for only about three minutes. Wlodaver assigned roles to her team, and five people went to work attaching an emergency umbilical cord to get baby Addyson's heart rate up.
“If (she) had been born some other places, there may not be a baby,” she said.
Addyson McCall weighed one pound, eight ounces when she was born. She remains in the neonatal intensive care unit at The Children's Hospital.
Doctors have said, based on the tests they've run, her brain development is fine, and Addyson doesn't appear to have been affected by the rushed delivery.
