background: we aimed to compare clinical effects of sugammadex versus combination of anticholinergic-anticholinesterase agents for reversing of nondepolarizing neuromuscular block in pediatric patients.materials and methods: a total of 60 pediatric patients  whom should be performed general anesthesia in the supine position were enrolled to this randomized double-blinded clinical trial.fentanyl...

The clinical pharmacology of neuromuscular blocking agents is described. During neuromuscular blockade, succinylcholine attaches to receptors in the motor end plate and depolarizes the neuromuscular junction, making the end plate refractory to acetylcholine. The nondepolarizing relaxants have a structure similar to that of succinylcholine and bind to the same receptors. Instead of depolarizing ...

To the Editor:—We read with interest article by Jonsson et al. suggesting that nondepolarizing neuromuscular blocking agents concentration-dependently inhibit human neuronal acetylcholine autoreceptors (nAChRs). The authors argue that the inhibition of the presynaptic 3 2 nAChR subtype plays an important role in tetanic and train-of-four fade seen during nondepolarizing neuromuscular blockade. ...

BACKGROUND Nondepolarizing neuromuscular blocking agents (NMBAs) are extensively used in the practice of anesthesia and intensive care medicine. Their primary site of action is at the postsynaptic nicotinic acetylcholine receptor (nAChR) in the neuromuscular junction, but their action on neuronal nAChRs have not been fully evaluated. Furthermore, observed adverse effects of nondepolarizing NMBA...

• 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...

Evidence has been presented to show that a second dose of suxamethonium is capable of producing a severe bradycardia in man. This response may be effectively prevented by the prior administration of certain non-depolarizing muscle relaxants namely tubocurarine, alcuronium, c-toxiferine and pancuronium in quantities of one-quarter or less of their muscle relaxant level. It is suggested that suxa...

Autonomy is defined as the capacity to think, decide, and act freely and independently on the basis of such thought and decisions. Three types of autonomy are distinguished: autonomy of thought, which embraces the wide range of human intellectual activities called "thinking for oneself"; autonomy of will, or the capacity to decide to do things on the basis of one's deliberations; and autonomy...

The antagonism of the nondepolarizing neuromuscular blockade is accomplished many times in a given day. Fortunately, the incidents of complications are low. If they do occur and are not recognized and treated properly, however, the results can be serious. In this article, the author reviews the curariform group of drugs, anticholinesterases, and anticholinergics, evaluating the antagonism of th...
