Research on the emergency surgery risks of medical support and coping strategies for taikonauts of Shenzhou-12 astronauts / 中华急诊医学杂志

ABSTRACT

Objective:This study aims to analyze the characteristics and basic principles of emergency surgery risks and anesthesia care of medical support at the landing site for China’s taikonauts of the Shenzhou-12, and to summarize China’s experience in medical support at the landing site for manned spaceflight, and ensure supports in special environments such as an emergency return of manned spaceflight.Methods:This study was carried out through literature research on relevant reports on the emergency surgery risks and aids of domestic and foreign astronauts at the landing sites, and summaries of the experience in medical support for taikonauts of spacecrafts from Shenzhou-5 to Shenzhou-11 at the landing sites. At the same time, according to the characteristics of Shenzhou-12 such as the long on-orbit time, the adjustment in the landing area, the optimization of the mission mode, and new search and rescue power, a series of organization, pre-arranged planning, equipment allocation, and effective anesthesia treatment plan were proposed and inspected in practice.Results:Based on the original anesthesia care plan of medical support, the first-aid carrier was adjusted and modified, the first-aid procedure was optimized, a new generation of supraglottic airway opening tool, video laryngoscope, portable ultrasound, and other devices were added, and the anesthesia care plan at the landing site for manned spaceflight was formulated to provide strong support for the medical care of taikonauts that had stayed in the outer space for a long time.Conclusions:Upon the targeted improvement and process optimization, the anesthesia care plan of medical support for taikonauts of Shenzhen-12 in the landing area fully meets the anesthesia requirement of medical support in special environments such as the emergency return of the taikonauts that have stayed in the outer space for a long time under the new orbital altitude.
