A rapid, sensitive and specific liquid chromatography coupled to tandem mass spectrometry method was developed for the simultaneous quantification pig plasma of ketamine and its two principal metabolites, norketamine and dehydronorketamine. Three extraction procoles were assessed including acetonitrile precipitation, Oase™ microplate extraction, and liquid-liquid extraction. Oase™ microplate extraction induced no significant matrix effect, important signal/noise ratio and good recoveries, ranging from 82 to 87% for the considered compounds...

The over-the-counter antitussive dextromethorphan (DM) may have rapid antidepressant actions based on its overlapping pharmacology with ketamine, which has shown fast antidepressant effects but whose widespread use remains limited by problematic side effects. We have previously shown that DM produces antidepressant-like effects in the forced swim test (FST) and tail suspension test (TST) that are mediated in part through α-amino-3-hydroxy-5-methyl-4-isoxazole propionic (AMPA) and sigma-1 receptors, two protein targets associated with a faster onset of antidepressant efficacy...

Anesthesia for mice is commonly performed through the injection of parenteral agents via the intraperitoneal (IP) route. Variability in anesthetic sensitivities has been noted in mice resulting in inconsistencies in anesthetic depth and/or mortality. Anesthetic protocols that improve consistency and safety are needed. The objectives of this study were to assess the effects of intraperitoneal (IP) ketamine (95 mg/kg) and xylazine (7 mg/kg) alone or combined with lidocaine at 4, 8, or 16 mg/kg on time to loss (LRR) and return (RRR) of righting reflex, duration of immobilization and loss of pedal withdrawal response (PWR), body weight and histopathology in CD-1 mice...

Recording an accurate body temperature is important to assess an animal's health status. We compared temperature data from sedated cynomolgus macaques (Macaca fascicularis) to evaluate differences between rectal, infrared (inguinal and chest), and implanted telemetry techniques with the objective of demonstrating the diagnostic equivalence of the infrared device with other approaches. Infrared thermometer readings are instantaneous and require no contact with the animal. Body temperature data were obtained from 205 (137 male, 68 female) cynomolgus macaques under ketamine (10 mg/kg IM) sedation over a 3-mo period during scheduled physical examinations...

There is currently no available information regarding the veterinary management of Sunda clouded leopards (Neofelis diardi), either in captivity or in the wild. In this study, 12 Sunda clouded leopards were anesthetized between January 2008 and February 2014 for medical exams, and/or GPS-collaring. Seven wild-caught individuals were kept in captivity and 5 free-ranging animals were captured by cage traps. Two anesthesia combinations were used: medetomidine-ketamine (M-K) or tiletamine-zolazepam (T-Z). Atipamezole (0...

Gray short-tailed opossums are used in a wide variety of research in the areas of developmental biology, oncology, immunology, and comparative biology. Despite many frequent experimental manipulations of these animals under anesthesia, few studies to date have characterized the effects of anesthesia in this species. Our aim was to identify safe and effective injectable anesthetic combinations using ketamine and xylazine or ketamine and dexmedetomidine at doses of 40 mg/kg to 100 mg/kg for ketamine, 5 mg/kg to 10 mg/kg for xylazine, and 0...

BACKGROUND: Neuropathic pain is a chronic pain condition, which is resistant to therapy. Ascorbate was released because of the activation of glutaminergic neurons. Due to the important role of N-methyl-D-aspartate (NMDA) receptors in the pathophysiology of neuropathic pain, this study investigated the analgesic efficacy of ascorbic acid (AA) in neuropathic pain condition and the role of NMDA receptors in this effect. METHODS: For this purpose, adult male rats were randomly allocated to experimental groups (n=8 in each group)...

BackgroundN-methyl-D-aspartate receptor activation has been implicated in the pathobiology of inflammatory, nociceptive and neuropathic pain, opioid tolerance, opioid-induced hyperalgesia, and central sensitization. Some of those mechanisms underlie sickle cell disease(SCD)-associated pain.MethodsWe conducted an exploratory cohort study of SCD patients who during vaso-occlusive episodes (VOEs) received subanesthetic doses of the N-methyl-D-aspartate receptor antagonist, ketamine, as an adjunct to opioids. We sought to identify predictors of changes in pain scores and of the percentage of ketamine infusions associated with meaningful changes (≥20% reduction) in pain and opioid consumption...

See Huang and Liston (doi:10.1093/awx166) for a scientific commentary on this article.Human depression is associated with glutamatergic dysfunction and alterations in resting state network activity. However, the indirect nature of human in vivo glutamate and activity assessments obscures mechanistic details. Using the chronic social defeat mouse model of depression, we determine how mesoscale glutamatergic networks are altered after chronic stress, and in response to the rapid acting antidepressant, ketamine...

Chronic ketamine use leads to cognitive and affective deficits including depression. Here, we examined sex differences and neural bases of depression in chronic ketamine users. Compared to non-drug using healthy controls (HC), ketamine-using females but not males showed increased depression score as assessed by the Center of Epidemiological Studies Depression Scale (CES-D). We evaluated resting state functional connectivity (rsFC) of the subgenual anterior cingulate cortex (sgACC), a prefrontal structure consistently implicated in the pathogenesis of depression...

We investigated the incidence of post-intubation hypotension (PIH) in hemodynamically stable patients with STEMI requiring rapid sequences intubation (RSI) and medicated with ketamine or midazolam as induction agent. STEMI patients admitted between 1st January 2009 and 1st January 2017 who did not receive any type of inotropic support before the endotracheal intubation (ETI) was reviewed. PIH was defined as a reduction greater than 20% or a drop of systolic blood pressure (SBP) below 90 mmHg within 10 min from the administration of the induction agent [ketamine (1 mg/kg) or midazolam (0...

Eunice Yuen, Steven Swanson, Jeffrey M Witkin
The forced swim test (FST) is a commonly used preclinical animal behavioural model for prediction of antidepressant activity in humans. While the FST may qualitatively predict efficacy, less is known about the quantitative translation of FST data to human efficacious doses. Assessing quantitative translation allows better predictions of human efficacious doses and a higher chance of success in the drug development process. Dose-response and time-course FST experiments were carried out on mice using four marketed antidepressants (citalopram, desipramine, bupropion, desvenlafaxine) in addition to ketamine, all with varying mechanisms of action...

BACKGROUND: Stress is a prevailing risk factor for mood-related illnesses, wherein women represent the majority of those affected by major depression. Despite the growing literature suggesting that affective disorders can arise after a traumatic event is vicariously experienced, this relationship remains understudied in female subjects at the preclinical level. Thus, the objective of the current investigation was to examine whether exposure to emotional and/or psychological stress (ES) mediates depression-related outcomes in female mice...

INTRODUCTION: Anesthesia induction is often accompanied by a period of hemodynamic instability, which could be a significant problem in patients with compromised ventricular function. The aim of this study is to compare the hemodynamic responses to etomidate versus a combination of ketamine and propofol (ketofol) for anesthetic induction in patients with left ventricular dysfunction undergoing coronary artery bypass graft (CABG) surgery. MATERIAL AND METHODS: In a double-blind randomized clinical study, a total of 84 patients with ischemic left ventricular dysfunction (EF < 40%) were randomly assigned to two groups (A and B)...

Memantine and ketamine are clinically useful NMDA receptor (NMDAR) open channel blockers that inhibit NMDARs with similar potency and kinetics, but display vastly different clinical profiles. This discrepancy has been hypothesized to result from inhibition by memantine and ketamine of overlapping but distinct NMDAR subpopulations. For example, memantine but not ketamine may inhibit extrasynaptic NMDARs more effectively than synaptic NMDARs. However, the basis for preferential NMDAR inhibition depending on subcellular location has not been systematically investigated...

Todd Morrison, Chris Carender, Brendan Kilbane, Raymond W Liu
Effective treatment of pediatric both bone forearm fractures consists of timely restoration of anatomic alignment with manipulation and immobilization, often accomplished with the aid of procedural sedation in the emergency department setting. The current lack of consensus regarding a safe and optimal regimen may result in inadequate sedation, compromised quality of reduction, or patient harm. The current study was conducted to answer the following questions for pediatric both bone forearm fractures treated with closed reduction with either ketamine or propofol procedural sedation: (1) Is there a difference in the rate of unacceptable alignment 4 weeks after reduction? (2) Is there a difference in the rates of major sedation-related complications? Medical records, data on procedural sedation, and radiographs of 74 skeletally immature patients with diaphyseal or distal metaphyseal both bone forearm fractures treated with manipulation were reviewed (ketamine sedation, 26; propofol sedation, 48)...
