To explore the application value of unmanned aerial vehicle (UAV) technology in regional emergency medical rescue.

A total of 400 cases of emergency medical rescue from March 2023 to December 2024 were selected as the research objects and randomly divided into drone rescue group and traditional rescue group, with 200 cases in each group. The delivery time of materials, the time of transporting the wounded and the positioning accuracy were compared between the two groups, and the changes of vital signs in the process of transporting patients between the two groups were analyzed, and the intact rate of medical materials, the success rate of rescue and the success rate of transporting patients between the two groups were counted.

The delivery time of materials in UAV rescue group was shorter than that in control group (P<0.05), the transfer time of wounded was faster than that in control group (P<0.05), and the positioning accuracy was higher than that of the control group (P<0.05). There was no significant difference in heart rate, average arterial pressure and respiratory rate among the vital signs in the unmanned aerial vehicle rescue group during transportation (P>0.05). The heart rate in the vital signs in the control group increased faster during transportation than before (P<0.05). The average arterial pressure decreased and the respiratory rate increased (P<0.05), and the heart rate and respiratory rate of unmanned aerial vehicle rescue group were slower than those of traditional rescue group (P<0.05) and the average arterial pressure was higher than that of traditional rescue group (P<0.05). The intact rate of medical materials, the success rate of rescue and the success rate of patient transport in the UAV rescue group were higher than those in the control group (P<0.05).

The application of UAV technology in regional emergency medical rescue can significantly shorten the rescue time and improve the rescue efficiency, which has broad application prospects and development potential.
