• Understand the Clinical Presentation and Pathophysiology • Review the natural history and complications of posterior fossa tumors. • Discuss the pathophysiological progression from hydrocephalus to brainstem compression and neuroendocrine dysfunction. • Analyze Perioperative and ICU Management • Evaluate the anesthetic and surgical considerations for suboccipital craniotomy. • Examine ICU management strategies for post-operative complications including diabetes insipidus (DI), SIADH, and sepsis. • Identify and Respond to Critical Deterioration • Recognize early warning signs of neurological decline and systemic instability. • Discuss escalation protocols for GCS deterioration, fluid overload, and multiorgan failure. • Explore Diagnostic and Therapeutic Challenges • Differentiate between DI and SIADH in real-time ICU settings. • Review the role of imaging, lab monitoring, and endocrine support in managing neurocritical patients. • Reflect on System-Level Gaps and Improvements • Identify resource limitations affecting care (e.g., neuromonitoring, medication access, imaging delays). • Propose system-level solutions such as structured ICU neurosurgical pathways and early multidisciplinary involvement. • Promote Evidence-Based Practice and Quality Improvement • Apply current best practices in post-craniotomy care, including fluid and electrolyte management. • Discuss research questions and quality improvement opportunities, such as protocolized DI management and ICU early warning tools. • Foster Interdisciplinary Collaboration and Communication • Highlight the importance of coordinated care between neurosurgery, anesthesia, ICU, endocrinology, and infectious disease teams. • Encourage proactive communication with families and timely decision-making in complex ICU scenarios.
