Total parenteral nutrition during pregnancy.

Parenteral hyperalimentation or total parenteral nutrition has become an established therapy for patients with a wide variety of conditions that preclude oral feeding. Because pregnancy is an infrequent event in poorly nourished women with acute or chronic illness, total parenteral nutrition has not been widely used for pregnant patients. Some obstetricians believe that total parenteral nutrition entails risks in excess of its potential benefit to pregnancy and demands skills and knowledge that are either not available or are in limited supply. Sufficient favorable clinical experience has accumulated over the past 15 years so that total parenteral nutrition can be recommended in the management of malnutrition during pregnancy. The purpose of this report is to review the authors' experience and the literature about total parenteral nutrition during pregnancy.
