Surgery in space

Known physiological alterations during space travel include fluid redistribution, cardiovascular changes, and bone and muscle atrophy. In addition to common illnesses and conditions, space travellers may also develop novel pathologies that could arise from prolonged weightlessness, exposure to cosmic radiation, and trauma.

The authors note that the extreme environment of space produces several unique changes in human physiology that future practitioners of space-surgery must take into consideration.

"Manned space exploration has re-entered the public consciousness thanks to endeavours by SpaceX and Virgin Galactic, amongst others," said lead author Dr. Sandip Panesar, of the University of Pittsburgh. "I became interested in the practical aspects of performing surgery in space. My literature search revealed that potential pathology and trauma situations would differ from those on earth due to specific physiological adaptations to the extraterrestrial environment."
