The curious birth and upbringing of the newborn incubator


Pioneering physicians took inspiration from chickens and zoos and envisioned a means to reduce mortality in premature newborns. The idea worked, they strutted their stuff before the public, and the rest is medical history.

You may be surprised to learn that, once upon a time, it was standard practice for obstetricians, not pediatricians, to care for newborns in hospital nurseries. Surprising also is that many of the scientists who pioneered neonatal medicine (well before neonatology became a pediatric subspecialty) were-that's right-obstetricians. In fact, it was a French obstetrician who developed the first incubator for newborns, the first of many technological innovations that raised the rate of survival of premature infants.

Incubating inspiration

Interest in improving the care of premature infants among mid-19th century European obstetricians arose from the knowledge that a premature baby would thrive only if kept warm. The first infant warming device was a double-walled tub, developed in Russia. The space between the walls was continuously replenished with warm water to maintain the body temperature of the premature infant placed inside the tub.1 Later that century, starvation and war led to a rapid decline in the French birth rate, prompting the French government to direct obstetricians to reduce the high mortality rate among premature infants.

Dr. Tarnier first used the device at the Paris Maternité Hospital in 1880. Within three years, he demonstrated a 50% reduction in mortality among premature infants who weighed less than 2,000 g.
