2023年8月8日 · Anesthetic gases (nitrous oxide, halothane, isoflurane, desflurane, sevoflurane), also known as inhaled anesthetics, are administered as primary therapy for preoperative sedation and adjunctive anesthesia maintenance to intravenous (IV) anesthetic agents (i.e., midazolam, propofol) in the perioperative setting.

2025年1月17日 · General anesthesia brings on a sleep-like state with the use of a combination of medicines. The medicines, known as anesthetics, are given before and during surgery or other medical procedures. General anesthesia usually uses a combination of medicines given through a vein and inhaled gases.

We create and implement high-quality, innovative anesthesia solutions that align with your patient, surgeon, and facility’s needs through a proven system of delivery.

An inhalational anesthetic is a chemical compound possessing general anesthetic properties that is delivered via inhalation. They are administered through a face mask, laryngeal mask airway or tracheal tube connected to an anesthetic vaporiser and an anesthetic delivery system.

2012年7月28日 · Anesthesia Gas. From the bygone days of chloroform and ether, the use of anesthesia gas has come a long way. Our current inhaled anesthetic agents are much more safe, more pleasant, and predictable. Most general anesthetics in adults are induced through the use of intravenous medications.

Workplace exposures to anesthetic gases occur in hospital-based and stand-alone operating rooms, recovery rooms, dental operatories, and veterinary facilities. Engineering, work practice, and administrative controls that help reduce these exposures in all anesthetizing locations, are identified and discussed.

2023年4月17日 · Gaseous anesthetics, used most commonly today, are a single gas nitrous oxide and volatile fluorinated liquids (isoflurane, desflurane, sevoflurane) that are administered via specific vaporizers that transform the liquids into gases that diminish and, at higher doses, eradicate patient awareness.

One minimum alveolar concentration (MAC) of a volatile anesthetic is the alveolar concentration of the gas, at 1 atmosphere, for which 50% of patients will not have a motor response to painful stimulus (ie, surgical incision). A MAC of 1.3 will eliminate motor response in 99% of patients.

2023年5月1日 · Inhalation anesthetics (nitrous oxide, halothane, isoflurane, desflurane, sevoflurane, most commonly used agents in practice today) are used for induction and maintenance of general anesthesia in the operating room. This review is a general overview of inhalation anesthetic agents.

2024年9月4日 · Anesthetic gases are volatile substances that, when inhaled, produce a state of controlled unconsciousness. They work by depressing the central nervous system, effectively blocking pain signals and sensory perception.
