[Drugs for intravenous induction of anesthesia: ketamine, midazolam and synopsis of current hypnotics].

Ketamine and midazolam form the endpoint of a series of articles about intravenous induction of anesthesia . Both substances can be used as single induction hypnotic drugs; however, in practice, this is unusual. Both substances, with the exception of a few very specific indications and clinical situations, are more frequently used in combination or with one of the more common alternatives propofol, barbiturates and etomidate.

[Drugs for intravenous induction of anesthesia: barbiturates].

The discovery of barbituric acid and research on its derivatives have long been of importance in advancements in modern anesthesia. Decades of clinical use of barbiturates worldwide and their abuse has led to an enormous amount of knowledge. Thiopental and methohexital are ultra-short acting derivatives of barbiturates.

[Drugs for intravenous induction of anesthesia: propofol].

In a series of articles dealing with hypnotics for induction of anesthesia, this article describes the development and current value of propofol. Its significance far exceeds that of a pure induction hypnotic (sedation in diagnostic and therapeutic procedures and on the intensive care unit). Propofol is also used for sedation in diagnostic and therapeutic procedures and on the intensive care unit.

[Etomidate for intravenous induction of anaesthesia].

The pharmacological and historical knowledge about the currently available intravenous induction hypnotics form the basis for the daily work of anesthetists. Side effects of using hypnotic induction agents must be anticipated and adequately treated. Decades of experience with using intravenous induction hypnotics have led to theoretical requirements for an ideal narcotic agent with a best possible side effect profile.
