In our research in addition to the standard intraoperative monitoring, which includes the assessment of ECG and saturation, the investigators would like to estimate muscle relaxation by using two different methods: a TOF-Cuff which additionally allows to measure inoperative blood pressure and TOF-Scan with different sensor. Our aim is to compare two different methods of muscle relaxation monitoring in patients who will administer muscle relaxant - mivacurium. After receiving painkillers and hypnotics, when the patient is falling asleep, the standard dose of mivacurium 0.2 mg / kg body weight will be administered. Then, painless simultaneous stimulation with TOF-Cuff and TOF-Scan devices will begin. Until intubation, measurements will be made in every 30 seconds and then every 5 minutes until extubation. Extubation will take place according to the guidelines when the TOF-Cuff measurement on the arm is greater than 0.9 - this is the value at which the patient is considered ready to start breathing on his own. The following will be documented: the initiation of drug administration, intubation, possible repeated doses of mivacurium 2 mg, antagonization, extubation, possible side effects (e.g., transient cardiac disturbances, reddening of the skin, lowering blood pressure, bronchospasm, erythema, urticaria) and technical problems.
