Seizure Bedside Bench: What You Do, What You Never Do, What You Saw

A seizure is a population of cortical neurons firing together without the usual braking, and everything you chart follows from that. Work the bedside in the correct order — four harmful options are hidden in the list and the bench will tell you exactly what each one breaks. Then switch to the second drill, tick the features you actually observed, and watch the classification build itself from your observations rather than from the scan.

One mechanism, every finding you chart

Phases of a generalized tonic-clonic seizure A cortical activity trace that is low and irregular at baseline, becomes high amplitude and continuous during the tonic phase, breaks into decreasing bursts during the clonic phase, then falls to a suppressed flat line during the postictal period. BASELINE TONIC CLONIC POSTICTAL CORTICAL ACTIVITY
Read the trace clinicallyThe tonic block is sustained motor-cortex discharge: the chest is fixed, no air is moving, and the patient goes dusky. That cyanosis is expected and brief, and it is not a reason to force anything between clenched teeth. The clonic bursts are that same discharge being interrupted by returning inhibition, which is why the jerks slow and then stop. The flat postictal stretch is a cortex out of neurotransmitter and running an oxygen debt — drowsiness, confusion, headache and muscle soreness for minutes to hours. Incontinence follows sphincter release, and the tongue bite is lateral, because the jaw closes on a tongue caught between the molars.
