Letter to the editor: "Association of hemoglobin drift and outcomes in patients with aneurysmal subarachnoid hemorrhage".

This letter commends the study by Wang et al. on the association between in-hospital hemoglobin (Hb) drift and outcomes in aneurysmal subarachnoid hemorrhage (aSAH) patients undergoing surgical clipping. The study's findings highlight the importance of vigilant Hb monitoring and timely interventions. Future research directions include exploring interventions to minimize Hb drift, such as preoperative optimization and aggressive transfusion protocols. Comparative studies and multi-center approaches could further validate these findings, enhancing the generalizability and applicability of the results. This research represents a significant advancement in neurosurgical postoperative management.
