After desflurane, Sevoflurane is the volatile anesthetic with the fastest onset .sevoflurane buy online
While its offset may be faster than agents other than desflurane in a few circumstances,
its offset is more often similar to that of the much older agent isoflurane.
While sevoflurane is only half as soluble as isoflurane in blood, the tissue blood partition coefficients of isoflurane and sevoflurane are quite similar.
Medical uses of Sevoflurane.
It is one of the most commonly used volatile anesthetic agents, particularly for outpatient anesthesia, across all ages, as well as in veterinary medicine.
Together with desflurane, sevoflurane is replacing isoflurane and halothane in modern anesthesia practice.
It is often administered in a mixture of nitrous oxide and oxygen.
Sevoflurane has an excellent safety record, but is under review for potential hepatotoxicity, and may accelerate Alzheimer’s.
There were rare reports involving adults with symptoms similar to halothane hepatotoxicity.
Sevoflurane is the preferred agent for mask induction due to its lesser irritation to mucous membranes.
it was discovered by Ross Terrell and independently by Bernard M Regan.
A detailed report of its development and properties appeared in 1975 in a paper authored by Richard Wallin, Bernard Regan, Martha Napoli and Ivan Stern.
The rights for sevoflurane worldwide were held by AbbVie. It is now available as a generic drug.
During the process of waking up from the medication, it has been known to cause agitation and delirium.
Adverse effects of Sevoflurane
Studies examining a current significant health concern, anesthetic-induced neurotoxicity
(including with sevoflurane, and especially with children and infants) are “fraught with confounders,
Concern regarding the safety of anaesthesia is especially acute with regard to children and infants,
where preclinical evidence from relevant animal models suggest that common clinically important agents,
including sevoflurane, may be neurotoxic to the developing brain,
and so cause neurobehavioural abnormalities in the long term; two large-scale clinical studies
(PANDA and GAS) were ongoing as of 2010, in hope of supplying “significant [further] information”
In 2021, researchers at Massachusetts General Hospital published in Communications Biology research that sevoflurane
may accelerate existing Alzheimer’s or existing tau protein to spread:
“These data demonstrate anesthesia-associated tau spreading and its consequences.
According to Neuroscience News, “Their previous work showed that it can cause a change (specifically, phosphorylation, or the addition of phosphate)
to tau that leads to cognitive impairment in mice.
Other researchers have also found that it and certain other anesthetics may affect cognitive function.”
