BACKGROUND
Guidelines advise for more than 20 years to use occlusive plastic wraps for temperature management during delivery room care but data on efficacy of different types of wrap are still scarce.
METHODS
A random sample of seven different types of plastic wrap was tested using prewarmed aluminium blocks.
RESULTS
The most effective wrap increased the time to cool by 2°C by one-third for the core and by 100% for the surface whereas the least effective wrap led to even faster heat loss compared with no wrap at all. 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.
背景
20 多年来，指南建议在分娩室护理期间使用密闭性塑料包裹来进行体温管理，但关于不同类型包裹的效果的数据仍然很少。
方法
使用预加热的铝块对七种不同类型的塑料包裹进行了随机抽样测试。
结果
最有效的包裹使核心温度的冷却时间延长了三分之一达到 2°C，而表面温度的冷却时间延长了 100%，而最无效的包裹与完全不包裹相比，甚至导致更快的热量损失。在所测试的所有性能中，最无效的包裹是由含有潜在有毒和麻醉单体的聚氨酯制成的。热量和水的保留与包裹厚度无关。
讨论
保温和保水能力的巨大差异需要谨慎选择包裹的类型，因为有些可能会适得其反。不应该使用含有聚氨酯的包裹。
