Experiments were performed with the mannequin either naked or wrapped in a flexible, plastic bag (with the head exposed) used to prevent excessive body water loss at delivery and during the following hours About 30% of the model's total surface was wetted with water. Our results demonstrated that body position does not modify dry and evaporative heat losses, whatever the experimental conditions. The plastic bag acts rapidly and reduces total heat loss by 30% to 34%, primarily through a reduction in evaporative water loss (between 5.4 and <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/mp3248-math-0006.png\" xlink:title=\"urn:x-wiley:00942405:media:mp3248:mp3248-math-0006\"\/>). When the bag is present, the uncovered surface of the head accounts for about 50% of the total heat loss. This simple and inexpensive solution can be used to prevent thermal stress and dehydration in very small premature neonates.<\/jats:p>","DOI":"10.1118\/1.2163248","type":"journal-article","created":{"date-parts":[[2006,3,3]],"date-time":"2006-03-03T23:07:51Z","timestamp":1141427271000},"page":"637-644","source":"Crossref","is-referenced-by-count":20,"title":["Effect of posture on the thermal efficiency of a plastic bag wrapping in neonate: Assessment using a thermal \u201csweating\u201d mannequin"],"prefix":"10.1002","volume":"33","author":[{"given":"Khalid","family":"Belghazi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Tourneux","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elmountacer Billah","family":"Elabbassi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurent","family":"Ghyselen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephane","family":"Delanaud","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Pierre","family":"Libert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,2,15]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"91","volume-title":"Temperature Regulation and Energy Metabolism in the Newborn","author":"Swyer P.
