Optimizing anesthesia depth to enhance seizure quality during electroconvulsive therapy in major depressive disorder

Table 1 Effects of anesthesia depth on electroencephalography seizure parameters

Parameter	qCON 60-70	qCON 50-60	qCON 40-50	P value
EEG seizure duration	Longer	Moderate	Shorter	< 0.05
Mid-ictal amplitude	Higher	Moderate	Lower	< 0.05
Maximum heart rate	Higher	Moderate	Lower	< 0.05
Post-ictal suppression	Higher (qNOX > 60)	Moderate	Lower (qNOX < 40)	< 0.05
Complication rates	No significant change	No significant change	No significant change	> 0.05

EEG: Electroencephalography; qCON: Quantitative consciousness; qNOX: Quantitative nociceptive.
