Compared to older children and adults, preterm infants have an impaired capacity to regulate water and electrolyte balance. Appropriate fluid and electrolyte management is critical for optimal care of low birth weight or sick infants, as fluid overload and electrolyte abnormalities pose significant morbidity. This review highlights basic physiological principles which need to be applied when prescribing parenteral fluids and builds upon published literature to outline a rational approach to initial fluid and electrolyte management of the preterm infant.<\/jats:p>","DOI":"10.3233\/npm-190309","type":"journal-article","created":{"date-parts":[[2019,10,5]],"date-time":"2019-10-05T03:33:30Z","timestamp":1570246410000},"page":"11-19","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":33,"title":["A physiological approach to fluid and electrolyte management of the preterm infant: Review"],"prefix":"10.1177","volume":"13","author":[{"given":"J.L.","family":"Segar","sequence":"first","affiliation":[{"name":"Deparment of Pediatrics, Medical College of Wisconsin, Milwaukee, WI, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,10,3]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.1542\/peds.30.6.909"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(71)80328-1"},{"issue":"12","key":"ref003","first-page":"CD000503","author":"Bell EF","year":"2014","journal-title":"Cochrane Database Syst Rev"},{"key":"ref004","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1983.tb09852.x"},{"key":"ref005","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1982.tb09621.x"},{"key":"ref006","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2001.004275"},{"key":"ref007","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2005.06.039"},{"key":"ref008","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(05)80746-2"},{"key":"ref009","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1992.tb12205.x"},{"key":"ref010","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1987.tb10535.x"},{"key":"ref011","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1995.tb13824.x"},{"key":"ref012","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1983.tb09801.x"},{"key":"ref013","doi-asserted-by":"publisher","DOI":"10.1203\/00006450-197909000-00024"},{"key":"ref014","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1998.tb00928.x"},{"key":"ref015","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2005.11.027"},{"key":"ref016","unstructured":"Bell EF SegarJL, OhW.
