What is the purpose of assessing for bradycardia after a craniotomy?

Assessing for bradycardia after a craniotomy is critical because bradycardia can be an indicator of increased intracranial pressure (ICP). Following a craniotomy, changes in brain physiology and potential swelling can lead to elevated ICP, which, in turn, may affect heart rate. The brain and heart are interconnected through various physiological mechanisms, including the autonomic nervous system. Specifically, increased ICP can trigger parasympathetic responses, resulting in bradycardia. Monitoring heart rate, therefore, becomes a vital part of neurological assessments in the postoperative period. Detecting bradycardia early can alert healthcare providers to underlying complications such as rising ICP, allowing for timely interventions to prevent further neurological deterioration. This proactive monitoring is essential for patient safety and effective recovery following brain surgery.
