[Characteristic of medical support and health care for Shenzhou-5 and Shenzhou-6 astronauts at main landing site].

Objective: To investigate the characteristics of medical support and health care for the Shenzhou-5 and Shenzhou-6 astronauts at the main landing site, with special emphasis on the technical requirements for two astronauts during flight, in order to provide reference data for medical support in the battle field and disasters.
Methods: The data associated with accidental injuries of astronauts during the space flight collected from foreign nations and domestically were reviewed retrospectively. Based on the experience in medical support for Shenzhou-5 and Shenzhou-6 astronauts and the special environments of field operations, a scheme for first-aid and emergent treatment were drafted for a system of organization, prophylactic measurements, equipment and their effective implementation pending the test in the real situation.
Results: Two sets of high-quality intensive care unit (ICU) equipment were set up in helicopters, and an ambulance was equipped with the instruments and facilities that could be used in the first-aid and surgical operation in case accident and injuries should happen. The three sets of highly mobile ICU mentioned above could cover a vast area of both grassland and desert at the landing site to ensure that the astronauts could be rescued should accident occur, reaction to emergency would be most rapid and technique and equipment would be best. This scheme of first-aid for emergency which might occur in astronauts would seem to be a scientific, reasonable and practical system and would also meet the need in battle field.
Conclusion: The first-aid scheme for astronauts at the main landing site, and its equipment, first aid strategies as well as it execution might provide an advanced system for medical aid and emergency treatment in the battlefield, disasters, and other special occasions.
