We will compare usual care (neostigmine) with sugammadex for reversal of a moderate rocuronium-induced neuromuscular blockade and assess the effect on diaphragmatic EMG activity of sugammadex versus neostigmine.

| Main Objective: Comparison of the effect on diaphragmatic EMG activity of sugammadex versus neostigmine. To assess diaphragmatic activity, a transesophageal EMG recorder can be used, like the NAVA catheter (“Neurally Adjusted Ventilatory Assist”). Recent reports use the EMG signal obtained via a NAVA catheter during the weaning process as a marker for weaning failure. The reports link electromyographic activity of the diaphragm (Edi)-derived indices to the rapid shallow breathing index, a commonly used parameter to assess weaning outcome. We propose a double blind randomised trial in healthy volunteers, to assess the different effects of sugammadex and neostigmine on the central respiratory drive, neuromechanical coupling and diaphragm strength. ;Secondary Objective: Assessment of the effect of neostigmine and sugammadex on the central respiratory drive and neuroventilatory efficiency, including diaphragmatic fatigue.;Primary end point(s): At the end of surgery when spontaneous breathing is resumed, good diaphragmatic function is essential. When faced with a certain degree of residual neuromuscular block (RNMB, or PostOperative Residual Curarization, PORC) anaesthetists nowadays have the option to choose between an acetylcholinesterase inhibitor (AchEI, e.g. neostigmine) or a selective relaxant binding agent (SRBA, sugammadex). Sugammadex can only be used with the steroidal neuromuscular blocking agents (NMBAs), like vecuronium and rocuronium. A sugammadex dosage of 2 mg/kg is recommended in case of spontaneous recovery up to at least the reappearance of the second twitch of the train-of-four (TOF, T2) following a rocuronium induced blockade. The use of neostigmine 70µg/kg on reappearance of the second TOF response, was described by Kirkegaard and colleagues. Our hypothesis is that by making nicotinergic acetylcholine receptors fee from rocuronium in the diaphragmatic neuromuscular junctions, instead of increasing the amount of acetylcholine, sugammadex will result | — |
