  • but as no account has been published, (so far as I have been able to ascertain), of the inhalation of ether being used to prevent pain in surgical operations as early as March, 1842. (wikipedia.org)
  • My friends think I would be doing myself injustice, not to notify my brethren of the medical profession of my priority of the use of ether by inhalation in surgical practice. (wikipedia.org)
  • Stage III (stage of surgical anesthesia): from onset of automatic respiration to respiratory paralysis. (wikipedia.org)
  • Horace Wells was a practicing American dentist in Hartford, Connecticut who is considered a pioneer in the use of surgical anesthesia. (wikipedia.org)
  • However, Morton's interest in surgical anesthesia was not solely influenced by Horace Wells, but also Charles T. Jackson and Nathan Cooley Keep. (wikipedia.org)
  • The 20th century saw the transformation of the practices of tracheotomy, endoscopy and non-surgical tracheal intubation from rarely employed procedures to essential components of the practices of anesthesia, critical care medicine, emergency medicine, gastroenterology, pulmonology and surgery. (wikipedia.org)
  • The goal of anesthesia is to achieve the endpoints required for the given surgical procedure with the least risk to the patient. (wikipedia.org)
  • Hospital
  • In January 1845, Massachusetts General Hospital (MGH) in Boston allowed Wells to demonstrate the method of anesthesia. (wikipedia.org)
  • This hospital is equipped with some of the state of art facilities including 500 mA Siemens X ray machine, , 2D diagostic ultrasound, large and small animal 4D ultrasound color Doppler units, phaco emulsifiers, operating microscope, 9" C arm image intensifier, inhalation anesthesia machines with different vaporizers, multiparameter patient monitors, oxygenators etc. 1.

  • general
  • 3 , 4 Potential mechanisms for either cognitive disorder or neurodegeneration after general anesthesia are numerous, including N -methyl-D-aspartate-mediated excitotoxicity, oxidative stress, suppression of cholinergic signal transduction, and enhancement of protein oligomerization. (asahq.org)
  • Female patient, aged 6 years and 8 months, 25 kg, diagnosed with pulmonary alveolar proteinoisis, who underwent whole-lung lavage by sequential lobar fiberoptic bronchoscopy under general anesthesia and spontaneous ventilation. (scielo.br)
  • This report describes the WLL by sequential lobar fiberoptic bronchoscopy in a pediatric patient under general anesthesia and spontaneous ventilation. (scielo.br)
  • WLL was then indicated and performed by sequential lobar fiberoptic bronchoscopy with the patient under general anesthesia. (scielo.br)
  • General Anesthesia - Unarousable even with painful stimulus. (wikipedia.org)
  • Guedel's classification is a means of assessing of depth of general anesthesia introduced by Arthur Ernest Guedel (1883-1956) in 1937. (wikipedia.org)
  • In 1847, John Snow (1813-1858) and Francis Plomley attempted to describe various stages of general anesthesia, but Guedel in 1937 described a detailed system which was generally accepted. (wikipedia.org)
  • The introduction of neuromuscular blocking agents (such as succinylcholine and tubocurarine) changed the concept of general anesthesia as it could produce temporary paralysis (a desired feature for surgery) without deep anesthesia. (wikipedia.org)
  • Desflurane (1,2,2,2-tetrafluoroethyl difluoromethyl ether) is a highly fluorinated methyl ethyl ether used for maintenance of general anesthesia. (wikipedia.org)
  • It has the most rapid onset and offset of the volatile anesthetic drugs used for general anesthesia due to its low solubility in blood. (wikipedia.org)
  • Although there has been a great deal of debate as to who deserves the most credit for the discovery of general anesthesia, it is generally agreed that certain scientific discoveries in the late 18th and early 19th centuries were critical to the eventual introduction and development of modern anesthetic techniques. (wikipedia.org)
  • Concurrent with these developments were the significant advances in pharmacology and physiology which led to the development of general anesthesia and the control of pain. (wikipedia.org)
  • In the 20th century, the safety and efficacy of general anesthesia was improved by the routine use of tracheal intubation and other advanced airway management techniques. (wikipedia.org)
  • The first attempts at general anesthesia were probably herbal remedies administered in prehistory. (wikipedia.org)
  • secretion
  • Laryngeal reflex is lost although inflammation of the upper respiratory tract increases reflex irritability, corneal reflex disappears, secretion of tears increases (a useful sign of light anesthesia), respiration is automatic and regular, movement and deep breathing as a response to skin stimulation disappears. (wikipedia.org)
  • muscle relaxation
  • Anesthesia is also used for producing muscle relaxation, suppressing reflexes, and producing loss of consciousness for purposes other than prevention of pain perception. (ccac.ca)
  • concentration
  • For a given anesthetic agent and a given MAC concentration, the BIS values are similar during wash-in and wash-out phases of anesthesia. (biomedsearch.com)
  • This enables the agent to be available at a constant vapor pressure, negating the effects fluctuating ambient temperatures would otherwise have on its concentration imparted into the fresh gas flow of the anesthesia machine. (wikipedia.org)
  • temporary
  • The purpose of anesthesia can be distilled down to three basic goals or end points: hypnosis (a temporary loss of consciousness and with it a loss of memory. (wikipedia.org)
  • include
  • The proposed factors affecting output include: Temperature Specimen density Weight, content of water and essential oils Consistency of material in the filling chamber Storage time of the vapor Inhalation method (breathing technique) Not all those have been scientifically tested. (wikipedia.org)
  • patient
  • Anesthesia enables the painless performance of medical procedures that would cause severe or intolerable pain to an unanesthetized patient. (wikipedia.org)
  • In preparing for a medical procedure, the health care provider giving anesthesia chooses and determines the doses of one or more drugs to achieve the types and degree of anesthesia characteristics appropriate for the type of procedure and the particular patient. (wikipedia.org)
  • purpose
  • A vaporizer or vaporiser (a 'vape') is a device used to vaporize the active ingredients of plant material, commonly cannabis, tobacco, or other herbs or blends for the purpose of inhalation. (wikipedia.org)
