Routine Prenatal Care: Third Trimester

The Challenge

During the third trimester (29–40 weeks or more) the fetus continues to grow and develop, with full maturation in organ function being established, maternal physiology continuing to change, and the cervix and uterus preparing for the processes of childbirth. Prenatal care during this period continues to be directed toward monitoring the progress of the pregnancy and detecting treatable complications.

• Scope of the Problem: It is during the third trimester that the uterus and fetus prepare for labor and delivery. It is also during this phase of pregnancy that complications such as pre-eclampsia, bleeding, complications of diabetes or hypertension, abnormalities of growth or amniotic fluid, and preterm labor may arise.

• Objectives of Management: To protect the health and well-being of the mother and fetus.
