Use of a Polyethylene Bag to Reduce Perioperative Regional and Whole-Body Heat Losses in Low-Birth-Weight Neonates

Table 3

Skin heat losses (kJ·h⁻¹·kg⁻¹) for the NW and W groups (as calculated by the mathematical model) in the incubator and at the end of the catheter placement procedure. + = convective + evaporative heat losses from the respiratory tract; BHL: whole-body heat loss; : basal metabolic heat production.
