When does rebleeding occur in subarachnoid hemorrhage? Revisiting rebleeding cases with a focus on blood pressure

The paradigm is the current understanding of subarachnoid hemorrhage (SAH) and its treatment, particularly focusing on the prevention and management of rebleeding. This includes established diagnostic methods (CT, CTA, DSA), treatment approaches (surgical clipping, interventional radiology), and the role of blood pressure management in influencing outcomes.

This preprint falls under the "Normal Science" classification due to its focus on refining existing knowledge within the established paradigm of SAH management. The research investigates the timing of rebleeding and its relationship with blood pressure, aiming to improve the understanding and potentially refine current treatment protocols. The study does not challenge the existing paradigm or propose radical new theories but works within the accepted framework to address specific questions and optimize current practices. While the study identifies a potential optimal blood pressure range (101-160 mmHg) before securing the culprit lesion, this finding represents a refinement of existing blood pressure management strategies, not a paradigm shift. The research contributes to the ongoing "puzzle-solving" activity characteristic of normal science within Kuhn's framework.
