A comparison of a prototype electromyograph vs. a mechanomyograph and an acceleromyograph for assessment of neuromuscular blockade.

Abstract in brief

• The study compares three devices—electromyography, mechanomyography, and acceleromyography—for measuring neuromuscular blockade during anesthesia, finding electromyography closely resembles mechanomyography but is less available.
• Acceleromyography is the most commonly used in clinical practice but tends to produce higher train-of-four ratios, which can complicate interpretation of neuromuscular blockade levels.
• Overall, electromyography provides the most accurate assessment, similar to the laboratory gold standard (mechanomyography), but is less practical for widespread clinical use compared to acceleromyography.]
