A Smartphone Video Transmission System for Verification of Transfusion.

A physician-staffed helicopter emergency medical service called a doctor helicopter (DH) in Eastern Shizuoka was equipped with a smartphone video transmission system in April 2018. We herein report on the introduction of this system for the verification of transfusion in the DH. A 51-year-old man visited a local hospital after cutting his left neck himself. He was diagnosed with jugular vein injury and underwent compressive hemostasis. As he entered profound hemorrhagic shock, he underwent tracheal intubation, massive fluid resuscitation, and administration of 3 vasopressor agents to maintain circulation. The Eastern Shizuoka DH was requested to transport this patient. After making contact with the patient, the staff of the DH started prehospital transfusion. Because this was the first case of transfusion in a prehospital setting for our hospital, we held a meeting in which we used a smartphone video transmission system to verify the condition surrounding the transfusion in the DH. By reviewing the video record, we confirmed that the transfusion was performed safely and correctly in the prehospital setting. This smartphone video transmission system was useful for verifying the activity of the staff in the DH.
