Introduction
In fact, seizures following craniotomy are a relatively common phenomenon, and patients need not be overly concerned. These seizures—manifesting as epileptic episodes—are directly linked to neuronal injury and result from abnormal, ectopic electrical discharges in brain cells. The instability of neuronal electrical activity is what leads to the occurrence of seizures.
Seizures: Commonly referred to in lay terms as “sheep-attack epilepsy” or “convulsions,” seizures are one of the most frequent postoperative complications following brain tumor surgery. In fact, some patients experience seizures even prior to surgery—particularly those with tumors involving cerebral cortical regions such as the frontal lobe, temporal lobe, or insula.
What to do if convulsions occur after craniotomy
In fact, convulsions following craniotomy are a relatively common and expected phenomenon; patients need not be overly anxious. These convulsions result from abnormal, ectopic neuronal discharges—directly linked to neuronal injury sustained during surgery. Unstable electrical activity generated by damaged neurons triggers the convulsive episodes. Such postoperative seizures can typically be well-controlled with antiepileptic medications—for instance, carbamazepine—under physician guidance.
Craniotomy—also known as trepanation—is a type of neurosurgical procedure involving mechanical opening of the skull to perform non-routine interventions. Due to its high inherent risk, even minor technical errors by the surgeon may lead to permanent brain injury, rendering this procedure ethically and clinically controversial. Post-craniotomy sequelae vary significantly depending on multiple factors, including the severity and location of the initial injury, as well as the patient’s postoperative recovery course. Common long-term complications include prolonged coma, hemiplegia, aphasia, and epilepsy.
During an epileptic seizure, never forcibly restrain the patient’s limbs. Instead, gently assist the patient into a supine position. If vomiting occurs, promptly turn the patient’s head to one side to prevent gastric contents from refluxing into the trachea and causing airway obstruction. Simultaneously, remove any foreign objects from the mouth and clear vomitus promptly to avoid aspiration.
