This randomized controlled trial evaluated the precision of kinemyography versus electromyography for neuromuscular monitoring in children under 5 years old. In a cohort of 64 children, both methods demonstrated similar precision, with median repeatability coefficients of 0.06 at baseline. However, kinemyography showed decreased precision in non-certified use, with train-of-four ratios <0.9 occurring more frequently than with electromyography (33% vs 16%, P<0.05).
Key findings
- Median repeatability coefficients were 0.06 for both kinemyography and electromyography at baseline.
- Kinemyography precision was worse in non-certified use, with a median difference of 0.04.
- Train-of-four ratios <0.9 were more frequent in kinemyography than in electromyography (33% vs 16%, P<0.05).
- Electromyography maintained precision regardless of age or weight certification.
Why it matters
Understanding the precision of neuromuscular monitoring techniques in pediatric patients is crucial for ensuring effective anesthesia management and patient safety, particularly in populations where equipment certification is lacking.
