A few observations on Dr. Auvard's baby bed warmer

Currently, the number of stillbirths and premature babies is increasing. On average, it is 36 per 1000 births. In France, from 1840 to 1880, it increased from 32.57 per 1,000 births to 45.35 per 1,000. The desire for rational measures to save the lives of premature babies is very natural and gives tangible results. So, in the Maternit in Paris, since the introduction of the auvard hot water bottle, the mortality rate of premature babies has been reduced from 66% to 38%. The auvard hot-water bed is actually a Tarnier hot-water bottle, modified by Dr. Auvard.
