A DeKalb County jury cleared two doctors and a nurse of liability for the premature delivery and death of an infant whose mother was suspected of having a cervical problem shortly before giving birth.

The treating obstetrician, along with a maternal fetal medicine specialist and his nurse-midwife, were accused of failing to perform a procedure to close the mother’s “incompetent cervix”—a condition in which certain cervical muscles are weak and there is a danger of premature birth—when an ultrasound indicated there might be a problem.
