Fig. 2. Residual paralysis rate. Partial paralysis rate (percent) according to the delay between the administration of muscle relaxant and the arrival in the postanesthesia care unit (PACU). Partial paralysis was defined as a train-of-four (TOF) ratio less than 0.7 or less than 0.9. n = number of patients. *Significantly different from TOF < 0.9.
