Sedation for colonoscopies has become a bit controversial.At issue is the growing practice in some parts of the United States of giving patients unnecessary full anesthesia.
This is typically performed with the drug Propofol, a powerful sedative that must be administered and monitored by an anesthesiologist.
This colonoscopy anesthesia can be an expensive option if the anesthesiologist’s fee is not covered by your health insurance.
Their onset of action is rapid, and they are considered the preferred hypnotics as they do not significantly alter the various sleep stages due to their relative selectivity for the aforementioned receptor.
The representatives of this group are: Certain antihistamines with sedating properties (also known as first-generation antihistamines) are effective in treating mild forms of insomnia, although numerous undesirable side effects (such as their anticholinergic properties) make them less useful in comparison with benzodiazepines.
This group included more than three-fourths of patients with commercial insurance and two-thirds of those on Medicare.
Explanations vary for the use of full anesthesia during colonoscopies.In modern medicine they have been largely replaced by the benzodiazepines, primarily because they can induce tolerance, physical dependence and serious withdrawal symptoms.Nevertheless, certain barbiturates are still employed as anticonvulsants (phenobarbital) and to induce anesthesia (thiopental).They also have hypnotic, anticonvulsant and muscle-relaxing activities, but do not exhibit analgesic action or antipsychotic activity.The representatives of this group are: Nonbenzodiazepine “Z-drugs” sedative-hypnotics are drugs that differ in structure from benzodiazepines, but acts on a subset of the benzodiazepine receptor family known as BZ1.This type of sedation is endorsed by three gastroenterology societies for uncomplicated cases and can be administered by the gastroenterologists themselves.
