Twilight anesthesia is applied to various types of medical procedures and surgeries. It is a popular choice among surgeons and doctors who are performing anything from minor plastic surgeries to dental work, and procedures that do not require extensive operations or long durations in favor of less nausea and a limited recovery period after surgery.
Although it has a long terminal elimination half-life of 4 to 30 hours, plasma concentrations remain low after the typical induction dose. [33] Its advantages include “antiemetic, antipruritic, bronchodilatory, and anticonvulsant properties”, [34] which makes it suitable for patients with kidney or liver insufficiency. [35]
To induce general anesthesia, propofol is the drug used almost exclusively, having largely replaced sodium thiopental. [13]It is often administered as part of an anesthesia maintenance technique called total intravenous anesthesia, using either manually programmed infusion pumps or computer-controlled infusion pumps in a process called target controlled infusion (TCI).
Colonoscopies are performed under moderate sedation or anesthesia. You’ll be asleep, or near asleep, the whole time. The medications used will depend on a variety of factors, including where the ...
Generally, full mechanical ventilation is only used if a very deep state of general anaesthesia is to be induced for a major procedure, and/or with a profoundly ill or injured patient. That said, induction of general anaesthesia usually results in apnea and requires ventilation until the drugs wear off and spontaneous breathing starts.
Intubation (sometimes entubation) is a medical procedure involving the insertion of a tube into the body. Patients are generally anesthetized beforehand. Examples include tracheal intubation , and the balloon tamponade with a Sengstaken–Blakemore tube (a tube into the gastrointestinal tract ).
Video laryngoscopes are specialized fiberoptic laryngoscopes that use a digital video camera sensor to allow the operator to view the glottis and larynx on a video monitor. [ 13 ] [ 14 ] Other "noninvasive" devices which can be employed to assist in tracheal intubation are the laryngeal mask airway [ 15 ] (used as a conduit for endotracheal ...
Surgical airway management is often performed as a last resort in cases where orotracheal and nasotracheal intubation are impossible or contraindicated. Surgical airway management is also used when a person will need a mechanical ventilator for a longer period. Surgical methods for airway management include cricothyrotomy and tracheostomy.
