Zero-G Blood And The Many Horrors Of Space Surgery

In Expanse Season 3 Episode 11 "Fallen World", a medic described the risks of injury in microgravity. He said, "there is nothing you can do for the wounded in zero G except ease their pain. Without gravity, wounds can't drain. Blood pools and clots, tissue swells, any internal bleeding in a death sentence." I wondered if there were medical studies that supported this theory. Here's what I found.

no astronaut has ever had a major injury or needed surgery in space. If humans ever again venture past low Earth orbit and outward toward, say, Mars, someone is going to get hurt


In space, blood can splatter even more than it usually does on Earth, unconstrained by gravity. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.)
