The Medrano family grew by four on October 4, 2006, at Edward Hospital in Naperville when Anissa Medrano, 30, of Elgin, delivered quadruplets.
The Medrano quadruplets were conceived naturally, without fertility drugs or treatment. The odds of having natural or spontaneous quadruplets are estimated to be 1 in 512,000, according to Don Taylor, DO, medical director of perinatology at Edward Hospital.
Obstetricians Thomas Carver, MD and Thomas Chen, MD and a team of nurses and respiratory therapists delivered the three boys and one girl by Caeserean section at the end of Anissa's 30th week of pregnancy:
- Alexander, born at 1:01 p.m., 2 lbs. 7 oz., 14½ inches
- Alessandro, born at 1:01 p.m., 2 lbs. 10 oz., 16½ inches
- Michael, born 1:02 p.m., 3 lbs. 2 oz., 16½ inches
- Ysabell, born at 1:03 p.m., 3 lbs. 4 oz., 16 inches
"They all did exceptionally well. There were no complications, all of the babies were breathing on their own, and no mechanical ventilators were used," said Bob Covert, MD, medical director, Edward Hospital NICU and one of four neonatologists from DuPage Neonatology Associates who provided the immediate early care of the quadruplets following their births. Covert was joined by Vibha Thaker, MD, Rajeev Dixit, MD and Milen Peev, MD.
In Anissa's case, according to Dr. Taylor, she ovulated three eggs. Quadruplets developed when one of the eggs split, creating a set of identical twins (Alexander and Alessandro). Anissa learned she had quadruplets at about the seventh week of her pregnancy.
"Anissa had no significant problems, she was content and happy," says Taylor, who was joined by perinatologists Lee Yang, DO and Jill Moran, MD in Anissa's care prior to delivery. "I told her if we could get her to 28 weeks, that would be good. She almost reached 31, which was great."
"To get them to 31 weeks was really significant," says Covert. "It really increased the chances of avoiding potential problems and gave us optimism they'd do well."
Anissa is a certified nursing assistant. Her husband, Jesus, 35, works in construction. Anissa doubts she'll return to work any time soon. "I'll stay at home until they're at least two years old," she says. Anissa and Jesus, have two other children.
As a Level III NICU, Edward Hospital is recognized as the region's leader in the delivery and care of multiple births. The Medrano babies are the second set of quadruplets born at Edward. The Crommets - Josie, Allison, Maggie and Sophia - were born in 2001. The only quintuplets born in DuPage County, the Hortons, were delivered and cared for at Edward in 2004. Since 2001, 21 sets of triplets have been born at Edward.
