BACKGROUND Previous studies suggest that caudal administration of ketamine cause effective analgesia. The purpose of the current study was to compare the clinical effectiveness and plasma concentrations of S(+)-ketamine after caudal or intramuscular administration in children to distinguish between local and systemic analgesia. METHODS After induction of general anesthesia, 42 patients, aged ...

Ketamine, an anesthetic, analgesic, or sedative, is widely used for the treatment of cancer pain. Recently, ketamine has been also reported to be tumor repressor for inhibiting proliferation, invasion, and migration, and inducing apoptosis in many cancers. However, whether ketamine can induce the apoptosis of lung adenocarcinoma (LUAD) and which downstream molecular mediates its function remain...

The effect of co-administration of ketamine at the sub-effective dose with diazepam, chlordiazepoxide and clonazepam on their antinociceptive and protective efficacy against pentetrazole-induced seizures were studied in mice. Ketamine alone produces dose-dependent antinociception manifested as reduction in the number of writhing episodes evoked by acetic acid. In the writhing test, the antinoci...

Over the last couple of years, there have been numerous studies investigating the efficacy of ketamine, a non-competitive N-methyl-d-aspartic acid (NMDA) receptor antagonist as a rapid antidepressant. Most of the existing published literature describes the purported effectiveness of ketamine as a rapid antidepressant. The clinical efficacy of intravenous ketamine in the reduction of suicidal id...

T WO factors have increased interest in ketamine for postoperative analgesia. The first was the discovery of the N-Methyl-D-asparrate (NMDA) receptor and its role in central pain processing and spinal cord neural plasticity. 1 Ketamine is one of two clinically useful NMDA receptor antagonists available (the other is dextromethorphan). Ketamine binds non-competitively to the PCI, (phencyclidine)...

PURPOSE OF REVIEW Ketamine misuse and abuse is on the increase. This review focuses on recent studies on ketamine toxicity in recreational users and possible implications for the use of ketamine in chronic pain therapy. RECENT FINDINGS Urological toxicity, hepatotoxicity and cognitive deficits are all reported as adverse effects of the recreational use of ketamine. Urological toxicity and hep...

The N-methyl-D-aspartate (NMDA) receptor antagonist ketamine produces episodic memory deficits. We used functional magnetic resonance imaging to characterize the effects of ketamine on frontal and hippocampal responses to memory encoding and retrieval in healthy volunteers using a double-blind, placebo-controlled, randomized, within-subjects comparison of two doses of intravenous ketamine. Diss...

Ketamine is an anesthetic and a popular abusive drug. As an anesthetic, effects of ketamine on glutamate and GABA transmission have been well documented but little is known about its long-term effects on the dopamine system. In the present study, the effects of ketamine on dopamine were studied in vitro and in vivo. In pheochromocytoma (PC 12) cells and NGF differentiated-PC 12 cells, ketamine ...

BACKGROUND Nonconvulsive status epilepticus (NCSE) is a diagnosis that is often challenging and one that may progress to refractory NCSE. Ketamine is a noncompetitive N-methyl-d-aspartate antagonist that increasingly has been used to treat refractory status epilepticus. Current Neurocritical Care Society guidelines recommend intravenous (IV) ketamine infusion as an alternative treatment for ref...
