Sodium thiopental was a core medicine in the World Health Organization's List of Essential Medicines, [4] but was supplanted by propofol. [5] [6] [7] Despite this, thiopental is listed as an acceptable alternative to propofol, depending on local availability and cost of these agents. [7]
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).
It has a faster recovery time compared to midazolam and has a reduced incidence of post-operative excitement and results in a reduction in dose required of propofol and thiopental. [ 1 ] Midazolam is effective in children in reducing anxiety associated with separation from parents and induction of anesthesia . [ 2 ]
Commonly used intravenous induction agents include propofol, sodium thiopental, etomidate, methohexital, and ketamine. Inhalational anaesthesia may be chosen when intravenous access is difficult to obtain (e.g., children), when difficulty maintaining the airway is anticipated, or when the patient prefers it.
General anesthetics that agonize them are typically used to induce a state of sedation and/or unconsciousness. Such drugs include propofol, etomidate, isoflurane, benzodiazepines (midazolam, lorazepam, diazepam), and barbiturates (sodium thiopental, methohexital). [2] [3] [4]
Amobarbital, one of the chemical compounds that can be used as a truth serum. Sedatives or hypnotics that alter higher cognitive function include ethanol, scopolamine, 3-quinuclidinyl benzilate, potent short or intermediate acting hypnotic benzodiazepines such as midazolam, flunitrazepam, and various short and ultra-short acting barbiturates, including sodium thiopental (commonly known by the ...
Thiopental is a barbiturate with one of the C=O double bonds (with the carbon being labelled 2 in the adjacent diagram) replaced with a C=S double bond, R 1 being CH 2 CH 3 (ethyl) and R3) being CH(CH 3)CH 2 CH 2 CH 3 (sec-pentyl). Thiopental is no longer available in the United States. [47]
Thiopental; Metaraminol or ephedrine, where hypotension may occur secondary to the sedating drugs. Phenylephrine – This drug is administered to those with hypotension post intubation as a result of lidocaine, midazolam, fentanyl, Propofol, and ketamine. The dosages range from 50 to 200 μg in adults.
