Obstetrical nursing, also called perinatal nursing, is a nursing specialty that works with patients who are attempting to become pregnant, are currently pregnant, or have 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. Obstetrical nurses perform postoperative care on a surgical unit, stress test evaluations, cardiac monitoring, vascular monitoring, and health assessments. Obstetrical nurses are required to possess specialized skills such as electronic fetal monitoring, non stress tests, neonatal  resuscitation, and medication administration by continuous intravenous drip. Obstetrical nurses work in many different environments such as medical offices, prenatal clinics, labor & delivery units, antepartum units, postpartum units, operating theatres, and clinical research.
