Researchers also examined the use of resuscitation and delivery-room characteristics. As expected, the use of occlusive wrap and sodium-acetate-gel mattresses led to lower percentages of neonates with hypothermia. Of hypothermic neonates, 85% who were 28 weeks OB EGA or younger underwent positive-pressure ventilation or intubation, whereas only 76% of euthermic neonates underwent these procedures (P?=.04), suggesting an increased risk for hypothermia with these procedures.

研究者也检视使用复苏与产房的特征；一如预期，使用闭合包巾和醋酸钠凝胶床垫可以降低新生儿低温比率；低温新生儿中，85%的OB EGA不到28周，有接受正压呼吸或者插管，而只有76%的适温新生儿接受这些照护(P=。04)，表示这些照护会增加低温风险；St。
