Can Acceleromyography Detect Low Levels of Residual Paralysis?
Why the study?
Does acceleromyography accurately detect residual paralysis compared to mechanomyography in patients recovering from neuromuscular block?
Population
60 patients recovering from neuromuscular block
Comparison
Acceleromyography vs Simultaneous mechanomyography

Implication
May support acceleromyographic TOF 1.0 to exclude residual paralysis; leaves open need for prospective validation against mechanomyography.
Structured PICO
Does acceleromyography accurately detect residual paralysis compared to mechanomyography in patients recovering from neuromuscular block?
P
Population
60 patients recovering from neuromuscular block
I
Intervention
Acceleromyography (Group A: calibrated TOF-Watch S; Group B: uncalibrated, manually set at 50 mA, with and without normalization)
C
Comparator
Simultaneous mechanomyography
O
Outcome
Agreement between mechanomyography and acceleromyography and negative predictive values for detecting residual paralysis (mechanomyographic TOF < 0.9)surrogate
Acceleromyography requires a train-of-four recovery ratio of 1.0 to reliably exclude residual neuromuscular paralysis.
