Key result
Frontal EMG measured by Patient State Index monitor showed a strong positive correlation with Train of Four values during the extubation phase of general anesthesia (r=0.74).
Why the study?
The study aimed to examine the correlation between frontal EMG from PSI monitoring and TOF values to evaluate both muscle strength and anesthetic depth with a single monitoring technique.
Does frontal EMG measured by Patient State Index monitor correlate with Train of Four values during the extubation phase of general anesthesia?
Observational (n=100)

Effect estimate: r=0.74
Frontal EMG and PSI monitoring show a strong positive correlation with TOF during extubation, suggesting potential for evaluating both muscle strength and anesthetic depth with a single monitoring technique.
May inform extubation decisions via PSI EMG; hypothesis-generating and requires prospective validation before adoption.

Taş et al. (2023) conducted an observational in General anesthesia (n=100). Frontal EMG (Patient State Index monitoring) vs. Train of Four (TOF) monitoring was evaluated on Correlation between TOF and PSI (r=0.74). Frontal EMG measured by Patient State Index monitor showed a strong positive correlation with Train of Four values during the extubation phase of general anesthesia (r=0.74).
