Dexmedetomidine can also be used for procedural sedation such as during colonoscopy. [16] It can be used as an adjunct with other sedatives like benzodiazepines, opioids, and propofol to enhance sedation and help maintain hemodynamic stability by decreasing the requirement of other sedatives. [17] [18] Dexmedetomidine is also used for ...
This level, called moderate sedation/analgesia or conscious sedation, causes a drug induced depression of consciousness during which the patient responds purposefully to verbal commands, either alone or accompanied with light physical stimulation. Breathing tubes are not required for this type of anesthesia. This is twilight anesthesia. [2]
The lack of sedation also lowers the risk of the procedure since some people may have adverse reactions to sedative medications used during conventional colonoscopy. VC provides clearer, more detailed images than a conventional x-ray using a barium enema , sometimes called a lower gastrointestinal (GI) series.
A colonoscopy is typically performed under sedation. During that time, a gastroenterologist will insert a colonoscope, which is a flexible tube with a camera at the end, into the rectum, and will ...
During the procedure, the patient is often given sedation intravenously, employing agents such as fentanyl or midazolam. Although meperidine (Demerol) may be used as an alternative to fentanyl, the concern of seizures has relegated this agent to second choice for sedation behind the combination of fentanyl and midazolam.
During a colonoscopy, a doctor examines the large intestines by inserting a thin, flexible scope into the rectum and advancing it through the colon. The scope has an illuminated camera that ...
[45] [46] They are also used to lessen the sympathetic stress response, cough reflex during laryngoscopy or intubation, and supplement sedation by synergistic effects. [47] [48] The dose of sedative-hypnotic agents should be reduced due to the synergistic effects when combined with adjuvant agents. [48]
Fospropofol (INN [3]), often used as the disodium salt (trade name Lusedra [4]) is an intravenous sedative-hypnotic agent. It is currently approved for use in sedation of adult patients undergoing diagnostic or therapeutic procedures such as endoscopy .
