Space Health Alert Astronautfinds Cervical Vein Thrombosis on Space Station

BEIJING, March 6 (Xinhua) — A new study shows that an anonymous astronaut on the International Space Station has a deep vein thrombosis (DVT) in his neck veins, a blood clot in his neck vein, according tomedia reports. For privacy reasons, the astronaut’s identity and the exact time of his illness were kept secret, and personal lycins were omitted from the case study, only to know that the astronaut was on a six-month mission to the space station and only two months on the station, where deep vein thrombosis was detected.

Moore and NASA doctors agree that blood thinners are the best treatment for astronauts’ blood clots, but the astronauts have very limited drug options on the space station because the station has only a small supply of drugs.

This is the first time blood clots have been found on an astronaut’s body, and NASA has yet to develop a plan to treat the condition in a “zero gravity” environment.

Thrombosis specialist

Stephan Moll, a professor of medicine at the University of North Carolina at Chapel Hill School of Medicine and one of the experts hired by NASA to treat thrombosis, said in a statement that Moore was the only non-NASA physician to help NASA treat thrombosis.

When it was discovered that the astronauts had a thrombosis, the blood thinner Enoxaparin was very limited, and Moore helped NASA decide how to quantify the station’s inochin to effectively treat deep vein thrombosis while ensuring that astronauts did not run out of the drug in the next space cargo shipment.

Treatment process

Currently, astronauts with thrombosis have been injected with enoftoin for 40 days, and enofheparin is injected with the skin, and on the 43rd day of the astronaut’s injection of enoheparin, a batch of Apixaban drugs will be delivered to the space station via a supply ship. Apixaban is an anticoagulant oral drug used to prevent venous thrombosis and atrial fibrillation stroke.

Astronaut thrombosis treatment takes more than 90 days, during which time the astronaut sits under the guidance of a radiology team on the ground to perform an ultrasound on his neck, closely monitor thrombosis, and Mohr communicates with astronaut patients via e-mail and phone. Eventually the astronaut successfully completed a six-month mission to the space station and returned to Earth without blood clot severce.

More research is needed.

Ironically, the astronauts examined deep vein thrombosis when they performed an ultrasound on the neck to analyze how the body’s fluids were redistributed in a weightless state, but he did not have any abnormal symptoms. Without the test, researchers at the University of North Carolina said, no one would have known what would be like of a blood clot in the space environment.

Moore said there was a need for more in-depth research into the performance of blood and blood clots in space, a phenomenon that is common in the bodies of astronauts on the space station.

How to minimize the risk of deep vein thrombosis? Should the International Space Station be equipped with more drugs? All of these questions need to be answered, especially given that astronauts will carry out longer missions to the moon and Mars.
