The geriatric patient after trauma is a very fragile patient category. Any kind of movement impacts greatly, and remedial general pain relief can give risky side effects. We intend to give staff earlier in the care chain a tool to be able to give the patient a topical pain relief, by being able to mark with artificial intelligence in ultrasound images where the block should be applied. This would increase the safety, well-being and security for this vulnerable group of patients.
