Feeding the feeble: steps towards nourishing preterm infants.
This paper describes historic steps in feeding techniques and knowledge on the nutritional needs of premature infants. Devices to overcome weak sucking and swallowing were developed from 1851 to 1920, including tube feeding by gavage, medicine droppers and pipettes, feeding bottles with an air inlet, and beaked spoons for nasal feeding. Indwelling nastrogastric tubes were in use from 1951. For alleged safety concerns in the 1950s, postnatal feeding was postponed until a week of starvation was reached, and studies showed an association with neurological handicaps. The premature infant's elevated need for energy, protein, and minerals has been established since 1919. However, these remained controversial, and nutritional practices continued to lag 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 who were fed formula than in those who were fed human milk. Recently, probiotics were shown to reduce the risk of necrotizing enterocolitis. Nevertheless, compared with other aspects of neonatal medicine, there is still remarkably little evidence on how to feed preterm infants.
