METHODS: We searched all relevant medical literature, military reports, and travel industry documents on transfer of neurosurgical patients. This review was combined with a senior author's (M.J.) extensive relevant experience, to present important factors for neurosurgeons to consider during planning of aeromedical evacuation, highlighting potential preventable causes of deterioration en route.

RESULTS: Several criteria must be met for a transfer to be considered. The safe transfer of patients with craniospinal pathology requires efficient collaboration between the referring teams, the receiving units/departments, and the medical transfer service. Clear communication, qualified personnel, and appropriate transportation equipment must be available for the transfer. One must consider unique stressors during the air transfer, including the risk of hypoxia on certain types of flights. Vibration, loud noise, acceleration, and changes in barometric pressure en route may negatively affect the patient during transfer. Patient stabilization before transfer is a priority. Medical conditions that can potentially worsen in-flight should be corrected before transfer. The use of a checklist before departure is highly recommended and is included herein. The timing of transfer concerning the postoperative patient deserves special consideration.
