Background:
IONM latency and amplitude are widely variable depending on biometric data and endotracheal-tube related factors. We designed a study trying to identify a correlation between height, weight, BMI and intraoperative latency and amplitude values
Methods:
We preliminary analyzed 21 bilateral or monolateral thyroid procedures subjected to surgery in the department of General Sugery of Ospedale di Circolo di Varese - Universita' degli studi Insubria in November 2023. For each patient we collected data regarding V1 and R1 latency and amplitude, height, weight and BMI.
Results:
The correlation using R- Pearson test between BMI and V1, R1, S1 in the right side is respectively of: r = 0.069 (p= 0.84), r = 0.266 (p=0.048), r = - 0.020 (p=0.97). The correlation using R-Pearson test between BMI and V1, R1, S1 in the left side is respectively: r= 0.44 (p=0.011), r= 0.100 (p=0.75), r = - 0.27 (p=0.649). The correlation between height and Latency in V1, R1, S1 in the right side are: r=- 0.17 (p=0.71), r= -0.29 (p=0.52), r= 0. The correlation between height and latency in V1, R1, S1 in the left side are: r= 0.19 (p=0.05), r= 0.34 p=(0.33), r=0.26 (p=0.66).
Conclusions:
The initial analysis presents a basis of possible linear correlation between the biometric data and the depolarization and latency values evaluated with IONM. The numerical increase in data could confirm this trend in the next future.
