<qa>  What is the first step in monitoring neuromuscular blockade?Monitoring the neuromuscular blockade After induction of anesthesia and before administration of rocuronium, monitoring of neuromuscular blockade at the adductor pollicis muscle is initiated using acceleromyography TOF-Watch SX, Organon, Dublin, Ireland. After degreasing the skin, two surface electrodes are placed above the ulnar nerve near the wrist. After induction of general anesthesia, 50-Hz tetanic stimulation is applied for 5 sec and followed after 1 min by train-of-four TOF stimulation every 15 sec. If the response to TOF is stable, calibration and supramaximal stimulation are ensured by built-in calibration function CAL2. After at least 2 min of a stable baseline documentation of the response to TOF, rocuronium is administered.
