Development of a new device for improving accuracy and feasibility in neuromuscular monitoring with acceleromyography: a prospective randomized trial
- Conditions
- neuromuscular blockade monitoring during lumbar spinal surgery
- Registration Number
- JPRN-UMIN000041310
- Lead Sponsor
- Korea University Guro Hospital, Korea University College of Medicine, Seoul, Republic of Korea
- Brief Summary
The agreement between AMG and EMG in each group was assessed using the Bland Altman method. In group B, the repeatability coefficient of T1 was significantly lower during the recovery to T1 of 25% and TOF ratio of 0.9 (P????0.017 and 0.033, respectively), indicating higher precision. The mean differences of bias between AMG and EMG in TOF ratio of 0.9 were 6.839 in group NB and 3.922 in group B. The wide limits of agreement in group NB was slightly narrowed in group B but without significance.

- Primary Outcome Measures
Name Time Method The precision (i.e., variance during recovery to at least an accelomyographic TOF 0.90) between the group with brace and the group without brace compared with EMG.
- Secondary Outcome Measures
Name Time Method The difference (agreement) of the two groups (with brace and without brace) against the EMG (Bland-Altman plots).
