Safety during modern practice of anaesthesia is of great concern. Patients admitted daily for surgical procedures undergoing general anaesthesia for different types of operations are exposed to different risks, starting from the anaesthesia and ending with the surgical intervention. Aim of the study is to provide a comprehensive and evidence based data regarding the safety of the neuromuscular blocking agents used in modern anaesthesia practice, precisely Rocuronium and Pipecuronium, as well as the reversal agents such as Sugammadex, which is the sole agent in use in practice nowadays. A routine anaesthetic practice will be performed during the whole period of our study after strict patient selection criteria. Intraoperative standard monitoring as per local and international guidelines will be applied, this includes Spo2, ECG, NIBP/IBP, etCO2, BIS and Tetragaph for neuromuscular blockade monitoring. After induction of anaesthesia and prior to the administration of the muscle relaxant agent, a TOFC (Train of Four Count) will be registered as the starting point. Throughout the anaesthetic time, there will be continuous TOF monitoring. The anaesthesia will be maintained by sevoflurane. Also, the recruited samples will be divided according to the neuromuscular blockade agents administered, either Rocuronium or Pipecuronium. At the end of the surgical procedure, the time lapse between the administration of the reversal agent Sugammadex and a TOF ratio of 0.9 is registered as our primary end point. TOF measures will be performed in the postoperative period, to make sure there is no residual neuromuscular blockade in the early postoperative phase. The study will not only monitor the safety of the neuromuscular blocking agents in use, but will also monitor any signs of anaphylaxis due to their administration both intra and postoperatively.
