---|---|
NO_INTERVENTION: Moderate neuromuscular block
Subjects will receive moderate neuromuscular block, aimed at 1-2 twitches train of four
|
|
EXPERIMENTAL: Deep neuromuscular block
Subjects will receive deep neuromuscular block, aimed at 1-2 twitches post tetanic count
|
Deep neuromuscular block will be achieved with high dose rocuronium to achieve a depth of 1-2 twitches post tetanic count

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Leiden Surgical Rating Scale
Time Frame: during surgery
|
During the on average 3 hour procedure, the surgical condition will be scored by the surgeon using a 5-point surgical rating scale at 15 minute intervals(1: poor ; 5: optimal) Mean and standard deviation of the average of all leiden surgical rating scale will be reported.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Postoperative Measurements and Outcomes; Pain Scores
Time Frame: During post-anesthetic care unit stay (average stay 2 hours) at 15 minute intervals
|
Postoperative measurements and outcomes of during PACU stay, all scores are reported as means and standard deviation of the average over the follow up period -mean pain scores (numeric rating scale; 0 no pain - 10 worst pain imaginable) |
During post-anesthetic care unit stay (average stay 2 hours) at 15 minute intervals
|
Intraoperative Hemodynamic Conditions
Time Frame: Perioperative measurements at 15 minute interval (on average during 3 hours)
|
Perioperative average blood pressure will be reported, mean blood pressure ranging from 65 tot 110 millimeters mercury is considered normal
|
Perioperative measurements at 15 minute interval (on average during 3 hours)
|
Postoperative Measurements and Outcomes; Sedation Levels
Time Frame: During post-anesthetic care unit stay (average stay 2 hours) at 15 minute intervals
|
Postoperative measurements and outcomes of during PACU stay, all scores are reported as means and standard deviation of the average over the follow up period -ramsay sedation levels (0 = normal alertness, eyes open, responds normal to command 1 = drowsy with open eyes, closed and opened on command 2 = drowsy with closed eyes, opened in response to light auditory stimulus 3 = eyes closed, opened in response to rubbing the shoulder or a loud auditory stimulus 4 = eyes closed and opened only briefly in response to touching the subject 5 = eyes closed, unarousable by touch, aroused by painful 6 = unarousable by pain) |
During post-anesthetic care unit stay (average stay 2 hours) at 15 minute intervals
|
Postoperative Measurements and Outcomes; Saturation
Time Frame: During post-anesthetic care unit stay (average stay 2 hours) at 15 minute intervals
|
Postoperative measurements and outcomes of during PACU stay, all scores are reported as means and standard deviation of the average over the follow up period -blood oxygen saturation in percent levels between 95-100 are considered normal |
During post-anesthetic care unit stay (average stay 2 hours) at 15 minute intervals
|
Intraoperative Nociception Level
Time Frame: Perioperative measurements at 15 minute interval (on average during 3 hours)
|
The median and full range of the average nociception level index will be reported. The nociception level index consist of Ta multiparameter nonlinear combination of heart rate, heart rate variability, amplitude of the finger photoplethysmogram, skin conductance level, fluctuations in skin conductance, and their time derivatives, derived from random forest regression. Random forest is an algorithmic modeling approach that enables combining multiple parameters of different origin and discovering their complex nonlinear interactions. Normal range is between 10-20; 0 indicates no nociceptive events (in example, pain stimuli), 100 indicates severe painful stimuli. |
