The purpose of this study is to determine the effects of combined sevoflurane and nitrous oxide inhalation on mood, psychomotor performance, and the pain response in humans.
Despite theoretical benefits of intravenous agents, volatile agents remain popular. In a study comparing desflurane, isoflurane, and sevoflurane in a porcine model of intracranial hyperten...
The purpose of this study is 1) to investigate whether the use of BIS as a guide to the administration of inhaled anesthetic (sevoflurane or desflurane) compared with the use of hemodynami...
Sevoflurane is widely and frequently used in pediatric anesthesia due to its non-irritating airway properties, rapid induction and emergence. However, it is associated with emergence agita...
It is known that volatile anesthesia, such as sevoflurane, retain water and that this appears more pronounced in children. However, the mechanisms for this effect is unknown and it is not ...
Acid-sensing ion channels (ASICs) are neuronal Nachannels that are activated by extracellular acidification. Inhibiting ASICs is neuroprotective in mouse models of ischemic stroke. As inhalational ane...
The clinical manifestation of asthma in children can interfere with their daily activities. Music therapy may become one of the alternative approaches to making children feel comfortable during inhala...
Postoperative cognitive dysfunction in elderly patients has been related to neurodegenerative disorders and mortality. Sevoflurane anesthesia has been implicated in both postoperative cognitive dysfun...
Although desflurane and sevoflurane, the most commonly used inhalational anesthetics, have been linked to postoperative liver injury, their impact on liver regeneration remains unclear. We compared th...
Multiple exposures to anesthesia in children may increase the risk of developing cognitive impairment. Sevoflurane is an anesthetic that is commonly used in children during surgery. Cyclin-dependent k...
Gases or volatile liquids that vary in the rate at which they induce anesthesia; potency; the degree of circulation, respiratory, or neuromuscular depression they produce; and analgesic effects. Inhalation anesthetics have advantages over intravenous agents in that the depth of anesthesia can be changed rapidly by altering the inhaled concentration. Because of their rapid elimination, any postoperative respiratory depression is of relatively short duration. (From AMA Drug Evaluations Annual, 1994, p173)
Agents that induce various degrees of analgesia; depression of consciousness, circulation, and respiration; relaxation of skeletal muscle; reduction of reflex activity; and amnesia. There are two types of general anesthetics, inhalation and intravenous. With either type, the arterial concentration of drug required to induce anesthesia varies with the condition of the patient, the desired depth of anesthesia, and the concomitant use of other drugs. (From AMA Drug Evaluations Annual, 1994, p.173)
Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
Inhalation anesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anesthetic gas and oxygen are added so that no anesthetic escapes into the room. Closed-circuit anesthesia is used especially with explosive anesthetics to prevent fires where electrical sparking from instruments is possible.
Intravenous anesthetics that induce a state of sedation, immobility, amnesia, and marked analgesia. Subjects may experience a strong feeling of dissociation from the environment. The condition produced is similar to NEUROLEPTANALGESIA, but is brought about by the administration of a single drug. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed)
