Clinical Trial Summary

Many drugs have an influence on neuromuscular transmission. In clinical practice, neuromuscular blocking agents are commonly used, but even in the absence of neuromuscular blocking agents, anesthetic drugs can influence neuromuscular transmission. Especially volatile anesthetic agents have a clinical impact on neuromuscular transmission, they have been shown to prolong and deepen the effect of neuromuscular blocking agents. But even in the absence of neuromuscular blocking agents, volatile anesthetics can impair neuromuscular transmission. One mechanism of action is the desensitization of the acetylcholine receptors by shifting them from a normal to a desensitized state. This effect can weaken neuromuscular transmission by reducing the margin of safety that normally exists at the neuromuscular junction, or can cause an apparent increase in the capacity of neuromuscular blocking agents to block transmission.

In this study, the influence of sevoflurane and propofol on the maximum force, maximum speed of contraction and relaxation will be measured at the adductor pollicis in patients having general anesthesia without the use of neuromuscular blocking agents. Maximum force and speed of contraction and relaxation will be measured before and after anesthesia by either sevoflurane or propofol. Primary outcome is the influence of either anesthetic agent on maximum muscular force and speed of contraction - relaxation, and if this influence is greater for volatile anesthetic agents than for intravenous anesthetic agents.
