Objective:

To compare the time to TOFR ≥ 0.9 between acceleromyography (AMG) and electromyography (EMG) in children aged 3–24 months undergoing general anesthesia after administration of rocuronium 0.6 mg/kg.

Approach:

• Study Design: An observational analysis involving 100 pediatric patients aged 3 to 24 months undergoing elective surgery under general anesthesia, comparing neuromuscular monitoring techniques.
• Monitoring Techniques: Neuromuscular monitoring was performed using both acceleromyography (AMG) and electromyography (EMG) at either the tibial nerve (TN) or the ulnar nerve (UN) to assess the efficacy of each method.
• Data Collection: Data on TOF responses were recorded and analyzed to determine the time to TOFR ≥ 0.9, focusing on the differences between AMG and EMG.

Key Findings:

• Time to TOFR ≥ 0.9 was the primary outcome measured after administration of rocuronium 0.6 mg/kg.
• Monitoring was performed at both TN and UN to assess the efficacy of AMG versus EMG.

Interpretation:

The study aimed to establish the effectiveness of AMG compared to EMG in monitoring neuromuscular function in young pediatric patients.

Limitations:

• The study was limited to a specific age group (3 to 24 months) and may not be generalizable to older children or adults.
• Potential variability in neuromuscular response due to individual patient factors was not fully addressed.

Conclusion:

The findings contribute to understanding neuromuscular monitoring in pediatric anesthesia, particularly regarding the use of AMG and EMG.
