The main hypothesized benefit of preoperative fasting is to prevent pulmonary aspiration of stomach contents while under the effects of general anesthesia. Aspiration of as little as 30–40 mL can be a significant cause of suffering and death during an operation and therefore fasting is performed to reduce the volume of stomach contents as much as possible.
Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
If left untreated, aspiration pneumonia can progress to form a lung abscess. [5] Another possible complication is an empyema, in which pus collects inside the lungs. [6] If continual aspiration occurs, the chronic inflammation can cause compensatory thickening of the insides of the lungs, resulting in bronchiectasis. [6]
The drugs can slow digestion so much that it puts patients at increased risk for the problem, called pulmonary aspiration, which can cause dangerous lung damage, infections and even death, said Dr ...
Extraglottic devices are used in the majority of operative procedures performed under general anaesthesia. [28] Compared to a cuffed tracheal tube, extraglottic devices provide less protection against aspiration but are more easily inserted and causes less laryngeal trauma. [27]
General anaesthesia (UK) or general anesthesia (US) is medically induced loss of consciousness that renders a patient unarousable even by painful stimuli. [5] It is achieved through medications, which can be injected or inhaled, often with an analgesic and neuromuscular blocking agent .
Mendelson's syndrome, named in 1946 for American obstetrician and cardiologist Curtis Lester Mendelson, is a form of chemical pneumonitis or aspiration pneumonitis caused by aspiration of stomach contents (principally gastric acid) during anaesthesia in childbirth.
Adverse effects include a transient increase in serum glucose level, and poor wound healing (controversial). Medications include dexamethasone. Butyrophenones are typically administered as a single injection at the end of surgery. Adverse effects include prolongation of the QT interval on EKG. Medications include droperidol and haloperidol.
