Background Non-lethal weapons are widely used in guard duty on the border, stability maintenance and other tasks. Rational allocation of front-line rescue forces is the key to improve on-site treatment.
Objective To explore the effects of different medical rescue forces allocation strategies on the on-site treatment and evacuation of patients injured by non-lethal weapons in the plateau border region.
Methods The field support model based on agent was established by using simulation technology to simulate the medical service support process. From the two dimensions of casualty rescue and evacuation, this model was used to simulate the influence of different medical services allocation strategies on casualty rescue and evacuation under different combat casualty expectations.
Results Based on the composite brigade, when the combat casualty expectations caused by non-lethal weapons was less than 6%, the on-site deployment of 7 medical personnel and 3 evacuation units could meet the medical support requirements. When the expected personnel reduction was less than 10%, the on-site deployment of 8 medical personnel and 5 evacuation units could meet the medical support requirements.
Conclusion The increase of the number of on-site medical personnel can improve the passing rate of the treatment of the wounded, but it will put forward higher requirements for evacuation. Although the increase of evacuation unit can improve the evacuation efficiency of the wounded, it is easy to cause a high idle rate of transport capacity. Therefore, it is necessary to give full consideration to the balance between the casualty passing rate and the utilization rate of evacuation unit, and the on-site medical support force should be reasonably allocated.
