People will lose weight in outer space. What if there is a wound in the human body in outer space? Will it bleed? Still can't stop bleeding? If medical surgery is performed in outer space,

Suppose all conditions remain the same except weightlessness? 1. First of all, the aerodynamics of the operating room is a big problem (I'm not just talking about power). Because blood will still flow out, blood drops and so on may fly everywhere as long as they have the initial velocity of weightlessness ... just wipe them slowly with gauze, but it is always inevitable to spray them out and throw them out of the equipment. (The same is true of body fluids. As for hemostasis, the normal coagulation mechanism of human body has nothing to do with gravity, and the hemostasis methods of surgery (ligation, electrocautery, ultrasound, etc. ) has nothing to do with gravity. Secondly, the fixation of instruments and equipment is also a problem. The instruments in the sterile area have gone outside, or the contaminated things have gone to the operating area or something. Here, I naturally assume that there is still pollution in the environment. You don't want to sterilize the operating room by directly exposing it to space. _-3. In weightlessness, the operator's operation is bound to be affected, some habitual movements can't be used, and the feedback of limbs is different from before. Even some methods of exposing the operating field can't be used. For example, during the right abdominal surgery, if you are on the earth, you can tilt the bed slightly to the left to let the intestines get out of the way. 4. I don't know if there is any research on human respiratory and circulatory physiology under weightlessness (weightlessness+anesthesia) ... well, let's be optimistic. 1, long operation time may cause pressure ulcers due to long-term compression, such as prone to shoulder, hip and heel when lying on your back. If there is weightlessness, this risk will be reduced. Hey, can you tie it lightly when repairing it? . ) 2. For operations that require multiple positions, it may be easier to change positions. Ok, for the surgical trip in outer space, those who have the money (courage) come and sign up. ...
