Official title
The Effect of Different Depths of Neuromuscular Blockade, Assessed by Train of Four (TOF) Monitoring, On Driving Pressure and the Development of Postoperative Critical Respiratory Events in Abdominal Surgeries
Overview
This randomized controlled study aims to evaluate the effects of deep versus moderate neuromuscular blockade on intraoperative driving pressure and the development of postoperative critical respiratory events in patients undergoing abdominal surgery under general anesthesia.
Detailed description
Patients will be randomized into two groups:
Deep neuromuscular blockade group (TOF count 0, PTC 1-2) Moderate neuromuscular blockade group (TOF count 1-2) Driving pressure (Plateau pressure - PEEP) will be recorded intraoperatively. Postoperative critical respiratory events will be assessed within 30 minutes in the post anesthesia care unit (PACU).
Interventions
- Drug Rocuronium
Rocuronium will be administered intravenously as bolus and continuous infusion to achieve target neuromuscular blockade depth according to group allocation. Neuromuscular function will be monitored using quantitative TOF monitoring.
Primary outcome measures
- Mean Intraoperative Driving Pressure [Time frame: From immediately after intubation until the end of surgery (intraoperative period)]
Secondary outcome measures (1)
- Incidende of Postoperative Critical Respiratory Events [Time frame: From immediately after extubation and until 30 minutes after arrival to PACU]
