Mivacurium is a short-acting nondepolarizing muscle relaxant (NDPMR) with a benzyl-isoquinoline structure and rapid, spontaneous reversal. It is hydrolyzed by cholinesterase in plasma and its chemical structure favors histamine release, leading to cutaneous or cardiovascular symptoms, particularly when the dose is increased or when the drug is injected rapidly. Both duration of effect and reversal of mivacurium are less dose dependent than they are with intermediate-duration NDPMRs. ⋯ Neuromuscular blockade may be prolonged in patients with low plasma cholinesterase activity, particularly in individuals who are homozygous for the atypical plasma cholinesterase gene. Monitoring is therefore recommended when mivacurium is used. Provided patients have normal plasma cholinesterase activity, mivacurium is indicated for interventions that are short or of unpredictable duration when rapid reversal of neuromuscular blockade is required, or whenever anticholinesterase agents must be avoided.

Randomized Controlled Trial Clinical Trial[Effects of precurarization on oxygen arterial saturation measure with pulse oximetry and neuromuscular function].
To study changes in arterial oxygen saturation (SpO2) measured by pulse oximetry, and the effect of neuromuscular function after precurarization with different nondepolarizing muscle relaxants. ⋯ SpO2 measured by pulse oximetry is an effective method for monitoring breathing function in the precurarized patient, as it detects early changes in arterial oxygen saturation related to respiratory muscle weakness. The agent d-tubocurarine is recommended for precurarization, because of its scarce effect on neuromuscular function at the dose used in this study.

Case Reports[Electromyographic characteristics of postanesthetic tremor].
Postanesthetic tremor is a frequent complication during recovery from surgery. Its etiopathogenesis is poorly understood and its electromyographic characteristics have scarcely been studies. ⋯ None of the three patients had electromyographic signs typical of hypothermic patients with tremor. We conclude that the electromyographic signs of postanesthetic tremor should be studied further and consider it noteworthy that the recordings we made could be attributable to high levels of circulating catecholamines, leading to exacerbation of physiologic tremor manifested in the form of postanesthetic shivering.

[Inflation of the endotracheal tube cuff as an aid for blind nasotracheal intubation in patients with predicted difficult laryngoscopy].
Inflation of the tracheal tube cuff to facilitate blind nasal intubation as described by Gobarck in 1987 has been shown to be effective for increasing the rate of successful intubation from 45 to 95% in patients with no airway alterations. We aimed to assess the usefulness of this technique in patients with anatomical alterations of the airway, in whom difficult intubation was predicted. ⋯ Inflation of the tracheal tube cuff is useful for facilitating nasotracheal intubation in the awake patient.
