An analysis of patients with acute aortic dissection who were transported by physician-staffed helicopter

The present study aimed to determine whether or not patients with acute aortic dissection (AAD) treated by the staff of a doctor helicopter (DH) service while being transported from the scene or for interhospital transportation obtained a favorable outcome.

We retrospectively investigated all patients with AAD who were transported by DH between January 2015 and December 2019 using the registry data of the DH control room of our hospital.

One hundred five cases were enrolled in the present study. All patients were transported within 24 h from the onset. Male patients accounted for 55.2% of the study population, the average age was 71 years and the rate of Stanford A AAD was 51.4%. Regarding transportation, 61.6% of the patients underwent interhospital transportation, and 42.8% were transported to our hospital. All patients underwent drip infusion during transportation and 81.9% of the patients received drugs (e.g., depressors, pain killers and/or antiemetics). Two patients underwent tracheal intubation due to unconsciousness and profound shock with restless state, respectively. The systolic blood pressure after transportation to hospital was significantly higher in comparison to before transportation. No patients suffered cardiac arrest or showed a deterioration of vital signs. All patients were safely transported to the destination.

The present study suggests the safety of using a Dr. Heli to transport AAD patients from the scene and for interhospital transportation, even after the onset.
