With crewed deep space exploration on the horizon, preparation for potential astronaut health crises in space missions has become vital. Administration of anaesthesia and analgesia presents many challenges owing to constraints specific to space (physiologic and ergonomic challenges associated with microgravity) and nonspecific factors (isolation and lack of supplies). Regional anaesthesia can be the safest option; however, we hypothesised that the ergonomics of microgravity would compromise ease and accuracy of nerve blocks.

超声引导神经阻滞在模拟微重力中的可行性：深空任务期间区域麻醉的概念验证研究


随着载人深空探索的临近，为太空任务中潜在的宇航员健康危机做好准备变得至关重要。由于空间限制（与微重力相关的生理和人体工程学挑战）和非特异性因素（隔离和缺乏供应），麻醉和镇痛的管理带来了许多挑战。区域麻醉可能是最安全的选择;然而，我们假设微重力的人体工程学会损害神经阻滞的易用性和准确性。
