The least effective wrap concerning all capacities tested was made from polyurethane that contains potentially toxic and narcotic monomers. Heat and water retention did not correlate to wrap thickness.Discussion Large differences in heat and water retention capacity warrant a careful choice of the type of wrap as some might be counterproductive. Wraps containing polyurethane should not be used.Data are available upon reasonable request. Data are available to interested users for further corporate analysis.}, issn = {1359-2998}, URL = {https://fn.bmj.com/content/107/6/645}, eprint = {https://fn.bmj.com/content/107/6/645.full.pdf}, journal = {Archives of Disease in Childhood - Fetal and Neonatal Edition} }
