In a bench-top setting, pad surface temperatures were measured before, during and after a 12-h period of phototherapy (10 different LED light box-pad combinations). A prospective, cohort study of well babies at >34 weeks' gestation receiving phototherapy was then conducted to determine changes in pad and body temperatures during a 90-min phototherapy period. <b><i>Results:<\/i><\/b> In the bench-top study, the mean (95% CI) pad temperature was 21.8\u00b0C (21.5-22.1) before lights, 27.0\u00b0C (26.5-27.5) after 12 h of lights, and 22.1\u00b0C (21.9-22.4) 8 h after turning off the lights (<i>F<\/i> = 366.1, <i>p<\/i> < 0.0005). The magnitude of change in pad temperature with phototherapy was linearly correlated with irradiance (<i>r<\/i> = 0.89, <i>p<\/i> < 0.0005). The pad plastic covering absorbed 13% of blue light from fibres. In the clinical study, the warmest pad temperature during phototherapy was 38.9\u00b0C. Axillary temperature increased by a mean (95% CI) of 0.3\u00b0C (0.1-0.5), <i>p<\/i> < 0.019, and exceeded 37.5\u00b0C in 4 babies. <b><i>Conclusions:<\/i><\/b> LED fibreoptic phototherapy pads are heated by high-intensity blue light. The thermal environment and temperature of babies should be monitored closely during LED fibreoptic phototherapy. A temperature probe placed between the skin and the pad will not accurately reflect the core temperature during fibreoptic phototherapy.<\/jats:p>","DOI":"10.1159\/000464318","type":"journal-article","created":{"date-parts":[[2017,4,26]],"date-time":"2017-04-26T21:06:48Z","timestamp":1493240808000},"page":"103-109","source":"Crossref","is-referenced-by-count":5,"title":["Heating of Newborn Infants due to Blue Light-Emitting Diode Fibreoptic Phototherapy Pads"],"prefix":"10.1159","volume":"112","author":[{"given":"Pei Ling","family":"Ng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tony","family":"Carlisle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marleesa","family":"Ly","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott Adam","family":"Morris","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2017,4,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.114.1.297"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1996.tb14034.x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD002060"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2011-1494"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1177\/000992289703600614"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1038\/sj.jp.7211789"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1055\/s-2002-36839"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD007969.pub2"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1055\/s-2000-10008"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2009.161158"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1203\/00006450-199310000-00026"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1203\/00006450-198208000-00018"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2011-3235"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1007\/s12098-013-1209-2"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/464318","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/464318","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/464318","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:33:07Z","timestamp":1745429587000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000464318"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":14,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2017,8,2]]}},"URL":"https:\/\/doi.org\/10.1159\/000464318","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
