The invention relates to a method (400) performed by an anesthetizing monitoring unit (110) configured to determine an anesthetized patient state, the method comprising disabling (410) an input port (111) of the anesthetizing monitoring unit (110), transmitting (420) a stimuli signal (S) using an output port (112) of the anesthetizing monitoring unit (110), enabling (430) the input port (111) of the anesthetizing monitoring unit (110) with a delay (ΔΤ) relative to the transmission of the stimuli signal (S), receiving (440) an evoked electromyography, EMG, response signal (S) in response to the transmitted stimuli signal (S), determine (450) an anesthetized patient state by determining a neuromuscular function value using properties of the stimuli signal (S) and the response signal (S). The invention further relates to an anesthetizing monitoring unit (110) and an anesthetizing monitoring system (100).
