Pharmacodynamics of non-depolarizing neuromuscular blocking agents.
When a clinical dose of a competitive neuromuscular blocking drug is given I.V. to a patient, a period of latency is followed by a progressive onset of blockade until a maximum is reached after several minutes. Thereafter, the intensity of block declines gradually. The precise relationship between the dose of drug and the time-course of the effect is complex, being dependent upon both pharmacok...
متن کاملNeuromuscular Blocking Agents
• Neuromuscular blocking agents are used to improve conditions for tracheal intubation, to provide immobility during surgery, and to facilitate mechanical ventilation. • The main site of action of neuromuscular blocking agents (muscle relaxants) is on the nicotinic cholinergic receptor at the endplate of muscle. They also have effects at presynaptic receptors located on the nerve terminal. • Su...
متن کاملNeuromuscular blocking agents: a review.
The author provides a review of the mechanism of neuromuscular transnission, as well as the Nechanisn of action and differences between curare and succinylcholine. Effects of these two relaxants on various organs and tissues are discussed, as are their onset of action, duration, elimination, and clinical uses. In order to understand how skeletal muscle re-laxants act, the mechanism of neuromusc...
متن کاملIndications for Neuromuscular Blocking Agents
©International Anesthesia Research Society. Unauthorized Use Prohibited. Almost thirty years ago, residual neuromuscular blockade was documented in a surprisingly high proportion of patients (30%), despite an almost systematic use of anticholinesterase agents.1 Since then, even with the development of shorter-acting neuromuscular blockers, pharmacological reversal, and more widespread use of ne...
متن کاملAntagonism of non-depolarising neuromuscular block: current practice.
There is now mounting evidence that even small degrees of postoperative residual neuromuscular block increases the incidence of adverse respiratory events in the Post Anaesthesia Care Unit and may increase longer-term morbidity as well. In the absence of quantitative neuromuscular monitoring, residual block is easily missed. A very strong case can be made for the routine administration of a non...
