Performance of a new auxiliary device based on wrist brace to improve accuracy and feasibility in neuromuscular monitoring with acceleromyography in prone-positioned patients undergoing lumbar spine surgery: a prospective randomized clinical trial
Study context
- Population
- Prone-positioned patients undergoing lumbar surgery under GA, rocuronium-induced NMB
- Participants
- 57 patients
- Comparison
- AMG with wrist brace vs without brace
- Bn = 29
- NBn = 28reference
- Primary endpoint
- Precision of AMG (repeatability coefficients of T1 and TOF ratio from nine consecutive measurements) and agreement with EMG (Bland-Altman) in prone position
Methodological detailsprospective
- Prospective
Primary result
As reported in the abstract
Repeatability coefficient of T1 · recovery to T1 of 25% and TOF ratio of 0.9
- Repeatability coefficient of T1 significantly lower in B (higher precision), recovery to T1 25%
- P = 0.017
- Repeatability coefficient of T1 significantly lower in B (higher precision), recovery to train-of-four (TOF) ratio 0.9
- 0.033
Further findings
Mean difference of bias
| Outcome | B | NB |
|---|---|---|
| Agreement between AMG and EMG at TOF ratio of 0.9 (Bland-Altman) | 3.922 (95% limits of agreement - 21.83 to 29.67) | 6.839 (95% limits of agreement - 26.54 to 40.22) |
Agreement between AMG and electromyography (EMG) at TOF ratio of 0.9 (Bland-Altman)
- Wide limits of agreement in NB slightly narrowed in B but without significance
