WitrynaSevoflurane is a fluorinated methyl isopropyl ether. It is sweet smelling and minimally pungent, and hence well suited to inhalational inductions. Because of its complete fluorination, sevoflurane has a very low blood solubility (among commonly used volatile anesthetics, only desflurane has a lower solubility). WitrynaSevoflurane is metabolized by cytochrome P450 2E1, to hexafluoroisopropanol (HFIP) with release of inorganic fluoride and CO2. Once formed HFIP is rapidly conjugated …

Analysis of sevoflurane degradation products in vapor phase …
WitrynaWe report an impurities and stability testing study on two different batches of three different commercial formulations of sevoflurane, the widely used fluorinated … Witryna27 cze 2012 · During one-lung ventilation, the end-expiratory sevoflurane concentration was stable at ∼1.3% but the mean (SD) presumed effect-site concentration declined initially from 58 (6.7) to 43 (4.7) μg.ml −1 (p = 0.011) before slowly recovering. A period of insufficient depth of anaesthesia is thus a risk during one-lung ventilation. WitrynaSevoflurane degradation was determined by measuring total impurities and hydrofluoric acid formation in three sevoflurane formulations stored in these vaporizers for … loan for hack reactor
