Continuous administration of neuromuscular blocking agents allows to perform a controlled neuromuscular block. Neuromuscular monitoring with different stimulation modes is a necessary prerequisite for the control of a depth block. This technique of administration appears to be attractive in cases when profound relaxation of muscles is desired until the end of surgery, then rapid recovery should follow. Laparoscopic procedures are typical cases. The neuromuscular blocking agents mivacurium and atracurium fulfill the criteria for minimal accumulation in the organism, both agents allow for rapid recovery of neuromuscular function. Recovery time can be shortened by antagonizing the block.
