When was ketamine first synthesized?
Ketamine’s history begins with phencyclidine, which was first synthesized in 1956 by chemists at Parke Davis Company (Maddox et al., 1965) who discovered ketamine’s unique and fascinating pharmacology. Phencyclidine was capable of causing the appearance of drunkenness in rodents, delirium in dogs, cataleptoid states in pigeons and anesthesia in monkeys (Domino and Luby, 2012). Although demonstrated to be a safe and reliable anesthetic in humans, it also caused an intense, prolonged emergence delirium that ultimately made it undesirable for human use (Greifenstein et al., 1958; Johnstone et al., 1959; Domino and Luby, 2012).
Is ketamine safe for general anesthesia?
Ketamine’s wide therapeutic range makes it one of the safest anesthetics available. General anesthesia can be induced with both IV and IM routes (Table (Table1)1) and maintained with repeated doses of 0.5–1 mg/kg (Domino et al., 1984). Good analgesia and sedation can also be achieved at subanesthetic doses (e.g., 0.2–0.8 mg/kg IV, 2–4 mg/kg IM), and infusions at subanesthetic doses (e.g., 0.5 mg/kg/h) may also provide continuous sedation and analgesia (Allen and Macias, 2005; Miller et al., 2011).
Is ketamine a CNS modulator?
Finally, given its CNS modulatory activity, ketamine should be used cautiously with other drugs that alter mood and perception, including alcohol, opioids, benzodiazepines and cannabis. Ketamine metabolism involves cytochrome P450 enzymes (Hijazi and Boulieu, 2002), and thus, concomitant use with drugs that inhibit cytochrome P450 metabolism may lead to inhibited ketamine metabolism and supratherapeutic toxicity.
Is ketamine a psychoactive substance?
The psychoactive properties associated with ketamine limit widespread clinical use. Even at subanesthetic doses (i.e., 0.1–0.4 mg/kg; Krystal et al., 1994), patients may experience perturbing dissociative symptoms. One study described ketamine at such doses producing four main psychological effects (Pomarol-Clotet et al., 2006): (1) a feeling of intoxication, comparable to the effects of other anesthetics and sedatives; (2) perceptual alterations in visual, auditory and somatosensory domains concomitant with symptoms of depersonalization or derealization; (3) referential ideas and delusions, often of misinterpretation and thought disorder; and (4) negative symptoms such as poverty of speech.
Does ketamine cause dizziness?
Adverse effects include hypersalivation, hyperreflexia and transient clonus (Corssen and Domino, 1966). Ketamine may also cause vestibular-type symptoms including dizziness, nausea and vomiting. Cardiopulmonary toxicity is rare, with effects limited to those caused by the transient sympathetic activation such as tachycardia, hypertension and palpitations (Weiner et al., 2000; Strayer and Nelson, 2008). Given ketamine’s wide therapeutic range, death by overdose is rare and usually involves other intoxicants or in the setting of trauma (Moore et al., 1997; Gill and Stajic, 2000).
Does ketamine affect the airway?
Despite the fact that a patent airway is usually maintained during exposure to ketamine, attention to airway protection remains essential, as partial obstruction and aspiration are still possible. Ketamine may increase salivary secretions (Corssen and Domino, 1966) and potentially increase the risk of laryngospasm, but this is rarely reported (Green et al., 2010). Other respiratory effects of ketamine include bronchodilation, likely through vagolytic and other neurally mediated mechanisms (Brown and Wagner, 1999). At high doses, ketamine may also directly affect airway smooth muscle, but this effect is unlikely to be of clinical importance (Brown and Wagner, 1999).
Is ketamine a sympathomimetic?
At both subanesthetic and anesthetic doses, ketamine is predominantly a sympathomimetic, producing increased arterial pressures and heart rate (Corssen and Domino, 1966) through direct stimulation of central nervous system structures (Traber et al., 1970). At higher doses (e.g., 20 mg/kg), however, ketamine also acts as direct myocardial depressant (Traber et al., 1968), and in the setting of compromised autonomic control (e.g., spinal cord transection, catecholamine depletion), these depressive effects may be unmasked. Ketamine also causes direct relaxation of vascular smooth muscle, though due to its sympathetically-mediated vasoconstriction, it has a relatively stable net effect on systemic vascular resistance (Diaz et al., 1976; Akata et al., 2001; Jung and Jung, 2012).

Ketamine arrived in France in 1970 after the 1968 publication by Lassner in ‘Les Cahiers d’Anesthésiologie’. 23 The teams of Vourc’h et al. 24 and Gauthier-Lafaye et al. 25 published the first French clinical trials. Ketamine provided potent analgesia but was less potent and of considerably shorter duration of action than PCP, particularly with regard to psychic problematic effects. The introduction of ketamine in Britain in late 1969 had been described as a ‘disaster’ from which the drug never recovered. 9 In 1970, hallucinations were considered so unpleasant that patient acceptance was much lower than with the barbiturates. 26
