Fiberoptic intubation under general anesthesia typically requires two skilled individuals. [38] Success rates of only 83–87% have been reported using fiberoptic techniques in the emergency department, with significant nasal bleeding occurring in up to 22% of patients.
General anaesthesia (UK) or general anesthesia (US) is a method of medically inducing loss of consciousness that renders a patient unarousable even with painful stimuli. [5] This effect is achieved by administering either intravenous or inhalational general anaesthetic medications, which often act in combination with an analgesic and ...
This procedure is used where general anesthesia must be induced before the patient has had time to fast long enough to empty the stomach; where the patient has a condition that makes aspiration more likely during induction of anesthesia, regardless of how long they have fasted (such as gastroesophageal reflux disease or advanced pregnancy); or where the patient has become unable to protect ...
During general anesthesia, the patient's muscles may be paralyzed in order to facilitate tracheal intubation or surgical exposure (abdominal and thoracic surgery can be performed only with adequate muscle relaxation).
Sometimes it’s injured during intubation (when a tube is passed down the throat during general anesthesia) or a tonsillectomy. Generally, it will heal up without treatment—sucking on ice chips ...
The technique involves the application of backward pressure on the cricoid cartilage with a force of 20–44 newtons [5] to occlude the esophagus, preventing aspiration of gastric contents during induction of anesthesia and in resuscitation of emergency victims when intubation is delayed or not possible.
a flexible device introduced through the mouth during some intubation procedures; if the stylet is in the trachea, while passing in, gives a sensation of bumps and then finally stops going in at a point, it indicates that it was gliding over tracheal rings and has stopped at one of the bronchi (the patient may even cough during this time); if ...
The first historical achievement in anesthesia occurred around 4000 BC in ancient Mesopotamia. [5] [10] [33] [34] [35] This was the advent of Ethanol(commonly known as ‘drinking alcohol’), the first general anaesthetic agent.
