Incidence of Postoperative Residual Curarization

Upon arrival of the spontaneously breathing patient in the Post-Anesthesia Care Unit, a researcher will evaluate the TOFR to detect any residual neuromuscular block using the acceleromyographic method at the level of thumb adductor.2 TOFR measurements will be performed 30 seconds apart. If the difference between the two measurements will be ≤ 0.1, the average value will be considered for the purposes of the analysis. In case of a difference \> 0.1, a third measurement will be taken and the average of the two closest results will be considered. If a residual block is detected sugammadex will be administered (2 mg/kg in the case of at least 2 contraction responses to TOF stimulation or 4 mg/kg in the case of no contraction response) to restore normal neuromuscular function , assessed by subsequent TOFR measurement.
