Drone-Assisted Organ Transport: A Scoping Review of Clinical, Regulatory, and System Readiness. [PDF]
Clin TransplantABSTRACT Organ transport remains a critical determinant of transplant success, with delays during transfer prolonging cold ischemia time (CIT) and increasing the risk of delayed graft function or organ discard. Uncrewed aerial vehicles (UAVs) have emerged as a potential means to enhance the speed, predictability, and resilience of transplant logistics.
