Summary

Emergency electroencephalography (EEG) findings can predict patient survival. Abnormal EEG patterns correlate with lower survival rates, making EEG a valuable prognostic tool in critical care settings.

Area of Science:

Neurology
Critical Care Medicine
Clinical Neurophysiology

Background:

Emergency electroencephalography (EEG) is crucial for diagnosing neurological conditions in hospitalized patients.
Prognostic indicators are vital for guiding treatment and managing patient expectations in critical care.

Purpose of the Study:

To correlate emergency electroencephalography (EEG) findings with patient survival rates.
To evaluate the prognostic value of EEG in a tertiary hospital setting.

Main Methods:

A prospective study involving 681 inpatients undergoing emergency EEGs.
Kaplan-Meier survival analysis was used to correlate EEG findings with survival outcomes over three months.

Main Results:

Specific EEG patterns were associated with distinct survival rates: normal/mild abnormalities (75%), continuous delta/epileptiform discharges (50%), and severe abnormalities (25%).
Isoelectric EEGs indicated immediate mortality.
Hepatic encephalopathy and liver disease were common indications for EEG, particularly in male patients.

Conclusions:

Emergency EEG findings serve as a significant prognostic tool.
EEG results can effectively differentiate survival rates in critically ill patients.
