[Bathing in bed accelerates the recovery of skin temperature after ethanol-loading]

Bathing in bed (BB) is an essential nursing technique applied to patients with restricted physical abilities. The aim of this technique is to keep the functions of the skin as an external barrier and to prevent the patients from infection and decubitus. However, the effect of BB on the blood circulation of the skin has not yet been identified, and the data observed are controversial. We have evaluated the effects of BB on the blood circulation of the skin by use of thermography. BB was applied on the right side of the back (RB) in 6 healthy female subjects who exposed both sides of their back (RB and LB) at room temperature. Ethanol was applied on the 5 x 5 cm area of RB and LB after BB, and recovery of the skin temperature was observed. After BB, the average temperature of RB was significantly lower than that of LB. This shows that BB decreases temperature of the skin exposed in the air probably due to the supply of water by washcloth. Recovery of the skin temperature after the ethanol-loading was accelerated on RB. This indicates that BB facilitates the response of the blood vessels in the skin.
