Obstetrical nursing, also called perinatal nursing, is a nursing specialty that works with patients who are attempting to become pregnant, are currently pregnant, or are recently delivered. Obstetrical nurses help provide prenatal care and testing, care of patients experiencing pregnancy complications, care during labor and delivery, and care of patients following delivery. Obstetrical nurses work closely with obstetricians, midwives, and nurse practitioners. They also provide supervision of patient care technicians and surgical technologists.
