Propofol pump controls nonconvulsive status epilepticus in a hepatic encephalopathy patient: A case report.

BACKGROUND

Status epilepticus is an emergent and critical condition which needs management without hesitation. Nonconvulsive status epilepticus (NCSE) tends to be less recognized, and its diagnosis is delayed in comparison with overt status epilepticus because of the absence of specific clinical signs. It is often difficult to make a diagnosis, particularly in patients with hepatic encephalopathy.

CASE SUMMARY: A 38-year-old man with a history of alcoholic liver cirrhosis presented with altered mental status; the initial diagnosis was hepatic encephalopathy. Although optimal treatment for hepatic encephalopathy was administered, the patient's mental status did not improve. A final diagnosis of NCSE was made by continuous electroencephalogram (EEG) monitoring. Treatment with levetiracetam and propofol pump was immediately started. The patient's consciousness gradually improved after discontinuation of propofol therapy, and no further epileptic discharge was observed by EEG monitoring. After 1 wk, the patient returned to full consciousness, and he was able to walk in the hospital ward without assistance. He was discharged with minimal sequela of bilateral conjunctivitis.

CONCLUSION

In cases of persistent altered mental status without reasonable diagnosis, NCSE should be considered in hepatic encephalopathy patients with persistently altered levels of consciousness, and EEG monitoring is very important. We also recommend propofol as a safe and efficient therapy for NCSE in liver cirrhosis patients.
