Explanation
Postoperative seizures may happen for several reasons:
Anesthesia and medications: Some anesthetic drugs or medications used during surgery can lower the seizure threshold. Metabolic imbalances: Changes in blood sugar, electrolytes, or oxygen levels during or after surgery can trigger seizures. Infections: Surgical site infections or meningitis can lead to seizures. Brain surgery: Patients having neurosurgery are at higher risk of seizures. Underlying conditions: Pre-existing epilepsy or brain abnormalities increase the chance of postoperative seizures. Stress and recovery: Physical stress and fatigue after surgery may also contribute.
Overall, seizures after surgery are not very common but should be reported immediately to medical staff for proper management.
