In 1839, he discovered, conceived, and promoted the practice of "phreno-magnetism", but relinquished his claims as mistaken by mid-1843. He was also involved in a number of scandals and rivalries, including a claim that he originated inhalation anesthesia for surgery before William T. G. Morton, who is generally credited with the discovery.
In January 1845, Massachusetts General Hospital (MGH) in Boston allowed Wells to demonstrate the method of anesthesia. Unfortunately, the patient did not respond to the dose of nitrous oxide given, which resulted in Wells’ endless contempt. Wells continued with extensive self-experimentation, such as repeated inhalation, with various chemicals.
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]
However, the agent may bind to a receptor with a weak interaction. A physical interaction such as swelling of nerve cell membranes from gas solution in the lipid bilayer may be operative. Notably, the gases hydrogen, helium, and neon have not been found to have anaesthetic properties at any pressure. Helium at high pressures produces nervous ...
Sevoflurane is an inhaled anesthetic that is often used to induce and maintain anesthesia in children for surgery. [17] During the process of awakening from the medication, it has been associated with a high incidence (>30%) of agitation and delirium in preschool children undergoing minor noninvasive surgery.

Until 1913, oral and maxillofacial surgery was performed by mask inhalation anesthesia, topical application of local anesthetics to the mucosa, rectal anesthesia, or intravenous anesthesia. While otherwise effective, these techniques did not protect the airway from obstruction and also exposed patients to the risk of pulmonary aspiration of ...
