Abstract

Abstract : Train-of-four ratios were recorded to assess the agreement between the TOF-Cuff and TOF-Watch, and residual paresis was assessed to evaluate the clinical utility of TOF-Cuff. Train-of-four ratios were evaluated using Lin concordance correlation coefficient and Bland–Altman analyses. Measured train-of-four ratios demonstrated high accuracy and precision over the entire range of train-of-four ratios. Although precision and Lin concordance correlation coefficients decreased with train-of-four ratios >0.7, none of the patients showed signs of residual paresis. Because TOF-Cuff underestimated train-of-four ratios in the recovery period, the clinical safety of train-of-four ratios >0.9 indicated by TOF-Cuff is unclear; the issue of residual paresis requires future research that rigorously evaluates outcomes.
