Experimental Spinal Taps On Children

While lumbar punctures—sometimes referred to as spinal taps—are often a necessary procedure, especially for neurological and spinal disorders, we can all agree that sticking a giant needle into someone’s spine is a recipe for excruciating pain. Yet, in 1896, a pediatrician named Arthur Wentworth decided to test the obvious. During an experimental spinal tap on a young girl, Wentworth noted how the patient cringed in pain during the procedure. Wentworth suspected that the operation was painful (it was believed to be painless at the time) but was not totally convinced. So he performed it again—on 29 infants and toddlers.

He eventually reached the conclusion that although temporarily painful, the procedure was very useful in helping diagnose illnesses. Wentworth’s findings received mixed reviews from his colleagues—some praised them while one critic denounced them as nothing more than “human vivisection.” Growing public indignation over the experiments later forced Wentworth to leave his teaching job at Harvard Medical School.
