With the development of national marine strategy, the importance of developing marine medicine and marine medical support capability has been highly regarded. In this paper, the problems regarding improvement on medical support for offshore trauma are discussed. Based on the analysis of the influence of environmental factors on offshore trauma treatment, and positive experience of trauma care practiced in the United States civilian ships and navy, we analyze the problems involving risk control for offshore trauma, establishment of standardized treatment and personnel training project, improvement of mobile rescue forces, and research for rescue technique and equipment, with the purpose to propose some effective and practical suggestions.
