Feeding the feeble

Abstract

This chapter describes historic steps in feeding techniques and knowledge about the nutritional needs of premature infants. Devices to overcome weak sucking and swallowing were developed from 1851 to 1920: tube feeding by gavage, medicine droppers and pipettes, feeding bottles with air inlet, and beaked spoons for nasal feeding. Indwelling nasogastric tubes were in use from 1951. For alleged safety concerns, postnatal feeding was postponed until a week of starvation was reached in the 1950s and studies showed an association with neurological handicaps. The premature infant’s elevated need for energy, protein, and minerals has been known since 1919. However, nutritional practice lagged behind theoretical knowledge. Concentrated formula was developed in the 1940s, parenteral supplementation in the 1960s, and human milk fortifiers in the 1970s. In the 1990s, necrotizing enterocolitis was found to be more frequent in infants fed formula than in those fed human milk. Recently, probiotics were shown to reduce the risk of necrotizing enterocolitis. Compared to other aspects of neonatal medicine, there is little evidence on how to feed preterm infants.
