 During procedure, surgeon who was blinded to random assignment could request that unblinded anesthetist change the randomized treatment conditions called a rescue intervention, if surgeon considered surgical conditions to be unacceptable. This was to be done systematically as follows: If the participant is on standard NMB, the preferred rescue intervention should be to increase the NMB to a depth of 1-2 PTCs; for such a participant the second option if participant is also on low insufflation pressure should be the increase of insufflation pressure by 4 mmHg. If the participant is already on deep NMB, the preferred option should be if participant is also on low insufflation pressure the increase of insufflation pressure by 4 mmHg.
