We compared the pungency and tolerability of three inhaled anaesthetics in a randomized, double-blind study. Eighty-one unpremedicated patients (n=27, each group) inhaled 2 MAC of isoflurane (2.3%), desflurane (12%) or sevoflurane (4%) for 60 s from an anaesthetic breathing circuit via a mask. Two blinded observers recorded coughing, complaints of burning and irritation, and how long the in…
Until 1950, there were few volatile anesthetic agents, such as diethyl ether and chloroform. It was dangerous or harmful to use them because they were explosive or caused cellular toxicity. In 1956, halothane was synthesized. Halothane is a powerful nonflammable anesthetic agent, and it quickly became widely used.
Sevoflurane is currently available in the United States from two manufacturers: Ultane (Abbott Laboratories, Inc.) and a generic product, Sevoflurane Inhalation Anesthetic (Baxter Healthcare Corp.). These products are rated therapeutically equivalent by the Food and Drug Administration, but there are some differences. Ultane is made in a single-step synthetic process and generic sevoflurane i…
Sevoflurane is produced by several manufacturers. Currently marketed sevoflurane formulations differ in their method of synthesis, impurities, containers in which they are sold, and water content. Of the various types of chemical degradation to which sevoflurane is susceptible, the most pertinent is degradation by Lewis acids (such as metal oxides and metal halides) to hydrofluoric acid and ot…
Volatile anesthetics provide myocardial protection during cardiac surgery. Sevoflurane and desflurane are both efficient agents that allow immediate extubation after off-pump coronary artery bypass grafting (OPCABG). This study compared the incidence of arrhythmias after OPCABG with the two agents.

Myocardial ischemia-reperfusion (I/R) injury significantly impacts recovery in both cardiac and noncardiac surgeries, potentially leading to severe cardiac dysfunction. Sevoflurane, a volatile anesthetic, is reputed for its protective effects against myocardial I/R injury, although evidence remains inconclusive. This systematic review and meta-analysis aim to clarify the cardioprotective eff…
Sevoflurane has been widely used in clinical anesthesia as an inhalation anesthetic. With the development of medicine, there have been several new applications in recent years, such as daytime surgery, labor analgesia, and combined nerve block for some surgeries. Moreover, as research progresses, it has been found that it not only has potential organ protection effects but can also be used …
General anesthesia is used for most major surgeries, and the most common side effects include headache, nausea, vomiting, and sore throat. Major breast surgery is associated with a high incidence of postoperative nausea and vomiting (PONV). We compared the postoperative nausea and vomiting of propofol-based total intravenous anesthesia (TIVA) and sevoflurane (SEVO) anesthesia under auditory evo…
