Summary
Time is Brain in stroke care. Optimizing prehospital diagnosis in large vessel occlusion strokes is crucial for saving neurons and synapses, improving patient outcomes.
Area of Science:
- Neurology
- Emergency Medicine
- Neuroscience
Background:
- Large vessel occlusion strokes cause rapid neural circuitry loss, with 'Time is Brain' highlighting the urgency.
- Every minute of delay in treatment results in significant neuronal and synaptic loss (1.9 million neurons and 13.8 billion synapses per minute).
Purpose of the Study:
- To review existing technologies for improving prehospital stroke diagnosis.
- To identify bottlenecks in the current stroke care pathway and propose optimizations.
Main Methods:
- Review of current diagnostic protocols for large vessel occlusion strokes.
- Analysis of the 'stroke chain of survival' and identification of prehospital care limitations.
- Examination of available technologies for enhancing early stroke detection.
Main Results:
- Prehospital diagnosis represents a critical bottleneck in the stroke chain of survival.
- Emergency Medical Services are the initial point of contact for over 50% of stroke patients.
- Existing technologies offer potential solutions to improve prehospital stroke assessment.
Conclusions:
- Optimizing prehospital stroke diagnosis is essential for improving outcomes in large vessel occlusion strokes.
- Technological advancements in prehospital care can significantly enhance the 'stroke chain of survival'.
