Fine Tuning of Neuro-muscular Blockade in Robot-assisted Prostatectomy

Assessing the routinely used protokoll for deep NM Block during robot-assisted prostatectomy in general anesthesia. The protocoll contains the repeated dosing of rocuronium according to the results of relaxometry performed with a TOFcuff relaxometer (RGB Medical, Madrid) during pneumoperitoneum. This is done by keeping the block level between 1 to 6 PTC (post tetanic counts). The scope of the study was to find out, to which percentage this protocoll permits the maintenance of block level inside of the desired range.
