Brief Summary
The depth of neuromuscular blockade (NMB) during surgery may cause a clinical dilemma between optimal surgical conditions and the risk of postoperative residual blockade. The aim of the study is to investigate if intense NMB improves surgical conditions during operation in patients scheduled for elective open upper abdominal surgery.

Outcome Measures
Primary Outcomes (1)
Surgical Rating Score
The final score for the surgical conditions of a patient defined as the average of all scores provided during the surgical procedure. (Rated on a 5 point subjective rating scale; 1: extremely poor, 2: poor, 3: acceptable, 4: good, 5: optimal)
After randomization every 30 minutes during the operation from first incision to last suture of fascial closure, up to 300 minutes
Secondary Outcomes (1)
The Surgical Rating Score During Fascial Closure
Immediatly after fascial closure
Study Arms (2)
Standard neuromuscular blockade
PLACEBO COMPARATORRocuronium 0.6 mg/kg followed by bolus rocuronium according to standard treatment decided by the attending anesthetist combined with saline infusion (placebo).
Deep neuromuscular blockade
ACTIVE COMPARATORRocuronium 0.6 mg/kg followed by rocuronium infusion with target level post tetanic count (PTC) of 0-1 combined with bolus saline (placebo) mimicking standard treatment.
