A Letter on Suspended Animation containing experiments shewing that it may be safely employed during operations on animals

"A Letter on Suspended Animation" by Henry Hill Hickman is a scientific publication written in the early 19th century. This work delves into the concept of suspended animation, particularly its potential application in surgical operations. Hickman presents a series of experiments conducted on animals to demonstrate the feasibility and safety of performing surgeries while the subjects are in a torpid state. In this letter, Hickman addresses T. A. Knight, sharing his findings on the effects of suspension of animation using carbonic acid gas and other methods. He reports that animals subjected to these conditions exhibited minimal suffering, with wounds healing rapidly and without complications. Hickman argues that surgeries could be performed with equal safety on insensate subjects compared to conscious ones, ultimately reducing patient anxiety and pain. His observations aim to encourage further exploration into this innovative approach in surgery, asserting that it could revolutionize the treatment of conditions requiring surgical intervention.
