Relationship of the Train-of-four Fade Ratio to Clinical Signs and Symptoms of Residual Paralysis in Awake Volunteers

Background Recovery of the train-of-four (TOF) ratio to a value > 0.70 is synonymous with adequate return of neuromuscular function, but there is little information available concerning the subjective experience that accompanies residual neuromuscular block wherein the TOF ratio is in the range of 0.70 to 0.90. Methods Ten American Society of Anesthesiologists' (ASA) physical status 1 volunteers were studied. Control measurements...
