Management of prolonged epileptic seizures and status epilepticus in palliative care patients

Abstract

Prolonged seizures and status epilepticus (SE) are relevant problems in palliative care. Timely recognition and effective early treatment with first- and second-line antiepileptic drugs (AEDs) may prevent unnecessary hospitalizations. Seizures should be recognized and addressed like any other symptom that causes discomfort or reduces quality of life. Use of alternative AED administration routes (buccal, intranasal, or subcutaneous) may offer possibilities for effective and individualized AED therapy, even during the last days of life. In hospice or home care, however, also intravenous treatment is possible via vascular access devices for long-term use. Aggressive unlimited intensive care unit (ICU) treatment of refractory SE in palliative patients is mostly not indicated. At worst, intensive care can be futile and possibly harmful: death in the ICU is often preceded by long and aggressive treatments. Metastatic cancer, old age, high severity of acute illness, overall frailty, poor functional status before hospital admission, and the presence of severe comorbidities all increase the probability of poor outcome of intensive care. When several of these factors are present, consideration of withholding intensive care may be in the patient's best interests. Anticipated outcomes influence patients' preferences. A majority of patients with a limited life expectancy because of an incurable disease would not want aggressive treatment, if the anticipated outcome was survival but with severe functional impairment. Doctors' perceptions about their patients' wishes are often incorrect, and therefore, advance care planning including seizure management should be done early in the course of the disease.This article is part of the Special Issue "Proceedings of the 7th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures".
