Brief Summary
Use of neuromuscular blockade (NMB) may improve the surgical work space in patients scheduled for laparoscopic surgical cases (e.g. hysterectomy, ovarian cystectomy, myomectomy). Clinical studies investigating this question often use a numerical or verbal rating scale for subjective evaluation of the surgical workspace. However, no good subjective rating scale have been developed or validated. Neither have possible inter-individual differences in use of such subjective scales been described. Purpose: The aim of this study is to validate different subjective rating scales to determine which scale is most useful among surgeons.

Outcome Measures
Primary Outcomes (1)
Subjective rating scale
The subjective rating scale with best possible interobserver agreement described by kappa statistics
Evaluation of video images within a time frame of in average 5 months after surgery
Secondary Outcomes (2)
Number of correct estimates of level of NMB
Evaluation of video images within a time frame of in average 5 months after surgery
Number of correct estimates of level of NMB according to grade of surgical experience
Evaluation of video images within a time frame of in average 5 months after surgery
Study Arms (2)
Deep NMB
ACTIVE COMPARATORVideorecordings and subjective ratings of intraabdominal surgical conditions during deep neuromuscular blockade and without neuromuscular blockade
No NMB
PLACEBO COMPARATORVideorecordings and subjective ratings of intraabdominal surgical conditions during no neuromuscular blockade and during deep neuromuscular blockade.
