Las Astronauts Due to the lack of gravity in space, the lack of gravitational scarcity and the omnic ovaries live, and they reduced the place to move. But the thing is especially complicated They were sick.
As the magazine is gathering Time In a statement, the first problem is the lack of gravity, which causes and affects disorders such as spatial adaptation (SAS) syndrome 67% and 75% of astronauts in space. It is manifested with dizziness, headache and nausea.
Still complicated, astronauts are whether someone shows signs A virus or a bacterial infection. First, the symptoms are bad, for example, the nasal breasts are poorly filtered without gravity.
In addition, more infections are: Slots limited to ships Where humans are breathing the recycled air, there are much less chance of washing themselves than the earth, touching the common surfaces repeatedly.
“Two years in the Micro Gravity Environment may cause deep changes in astronauts and aggressive microorganisms,” the doctor says Leonard jam, The University of Brown and the Rode Island Hospital infected with a disease expert a Time.
The main problem is the difficult relationship between zero gravity and germs. Earth a cough or sneezing infection discharges particles At a distance of 1 to 2 meters before gravity is imposed and separated from the air.
In space, the particles float everywhere. When they are landing, no They settle in a safe and separated place. The tool panels, food preparation surfaces and tests are everywhere. Victim astronauts usually have less training to fight the pathogen.
In addition, scientists may still fail to accommodate, the immune system may fail in space: Wounds are healed very slowly; D cells that fight infections send signals with low efficiency; The bone marrow is reproduced with low performance And the cells fight with low energy.
At the same time, The pathogens are strengthened.
“What happens if someone starts Spread a streptococcus What spreads quickly? Another scene is to reactivate a hidden bacterium, such as meeloidosis, which can cause pneumonia and spread, ”says Jemal.
Wounds and blows
Astronauts also emerge Wounds and blows, They are usually mild and are treated with consultation from the earth. But what happens when the case is serious?
In 1986, a medical evacuation was carried out only when a Soviet astronaut called Vladimir Wasudin Due to prostate infection he had to leave the orbit laboratory -7, as stated in an article published Mental bundle.
In the event of a real medical emergency that requires surgery, earth evacuation This is the only way that is currently Those astronauts get comprehensive treatment.
Micro Gravity has not been carried out any surgeryAlthough robotic surgeons have been trained with animals in space. As space trips are marketed, a day may require a space operating room, and technology is being developed so that possible surgery is easy and clean.
Scientists tried Aqueous sinkA dome full of salivary solution, when placed on a wound, can retain blood and body fluids.
At present, NASA Operates in many research and development projects To overcome the risks of going to deep space pose, including the closure of dental medicine and emergency injuries without a drill that can be accessed to astronauts without proper medical or dental training.
