Pediatric anesthesia & critical care
Comparison of supramaximal currents obtained by acceleromyography and electromyography for monitoring the adductor pollicis muscle in pediatric patients
Authors' conclusion
We found that the supramaximal current was significantly lower with EMG than with AMG.
Study context
- Population
- Patients aged 2–11 years undergoing elective surgery under GA, rocuronium 0.6 mg/kganalysed
- Participants
- 25 patients
- Exposure
- Electromyography (EMG) vs acceleromyography (AMG) on opposite arms
- Outcome
- Supramaximal current set by each device's calibration
Methodological detailssimultaneous paired measurement
- Simultaneous paired measurement
Main finding
As reported in the abstract
Supramaximal current
P < 0.001
Observational data: associations, not effects.
Secondary outcomes
Time from rocuronium to TOF count of 0 · significantly shorter with EMG
P < 0.001
Baseline and final train-of-four (TOF) ratios
- Both significantly lower with EMG than with AMG
Intubation conditions
- Vocal cords abducted
- 76%
- No movement to ETT insertion
- 96%
- Ease of laryngoscopy excellent for all patients
