1. Abstract
1.1. Background: Hypophosphatemia has a high incidence in very low birth weight preterm infants and may be related to inadequate intrauterine reserve, poor tolerance of enteral nutrition in the early postnatal period, and insufficient parenteral supplementation. Hypophosphatemia can be corrected by parenteral nutrition. Hypophosphatemia affects the growth and development of the child and may lead to serious sequelae.At present, there are still few reports on phosphorus supplementation for very low birth weight premature infants.
