Volatile anaesthetic agents share the property of being liquid at room temperature, but evaporating easily for administration by inhalation. The volatile anesthetics used in the developed world today include: Desflurane, isoflurane and sevoflurane. Other agents widely used in the past include ether, chloroform, enflurane, halothane, methoxyflurane.
Dental anesthesia (or dental anaesthesia) is the application of anesthesia to dentistry. It includes local anesthetics , sedation , and general anesthesia. Local anesthetic agents in dentistry
This seems to be especially problematic in dental anesthesia. [25] Like all the potent inhalational anaesthetic agents, it is a potent trigger for malignant hyperthermia. [5] Similarly, in common with the other potent inhalational agents, it relaxes uterine smooth muscle and this may increase blood loss during delivery or termination of ...
This is a list of local anesthetic agents. Not all of these drugs are still used in clinical practice and in research. Not all of these drugs are still used in clinical practice and in research. Some are primarily of historical interest.
General anesthetics are frequently administered as volatile liquids or gases. Inhalational anaesthetic substances are either volatile liquids or gases, and are usually delivered using an anaesthesia machine. An anaesthesia machine allows composing a mixture of oxygen, anaesthetics and ambient air, delivering it to the patient and monitoring ...
The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
It is often used together with other medications for anesthesia. [2] Common uses include during childbirth, following trauma, and as part of end-of-life care. [2] Onset of effect is typically within half a minute, and the effect lasts for about a minute. [1] Nitrous oxide was discovered between 1772 and 1793 and used for anesthesia in 1844. [3]
